Plastic pallet covers, often abbreviated as PPCs, are substantial, gusseted poly bags implemented for safeguarding pallets during storage and transportation. These versatile covers are frequently employed in diverse settings such as warehouses, storage areas, dockyards, and even home environments. Crucial for protecting palletized items from dust, moisture, and other environmental elements during transit and handling, plastic pallet covers serve as a cost-effective alternative to bulky, expensive pallet cover tarps. Available in a range of sizes and styles to meet varied storage and organizational requirements, these covers also help in minimizing damage from water, dust, and abrasion while allowing for branding or item labeling. Crafted from strong yet lightweight plastic, they offer efficient protection without significantly increasing shipment weight or volume. Ideally suited for temporary storage and shipping, plastic pallet covers stand out due to their user-friendliness, availability in both flat and gusseted forms, and customizable options to keep products secure and well-organized.
It is crucial to note that plastic pallet covers are intended for short-term use, offering a protective layer for goods but not designed to substitute for more durable options like pallet tarps or other sturdy storage containers. In the subsequent chapter, we will delve into the proper application of plastic pallet covers.
Employing pallet covers is straightforward; simply drape them over boxes on a pallet to secure items for temporary storage, whether inside or out. Moreover, thermal pallet covers can help control the pallet's temperature, maintaining warmth or coolness during storage and transit, especially beneficial for temperature-sensitive cargo.
Plastic pallet covers act as a reliable shield against contaminants such as dust, moisture, and spills. While disposable options are available, reusable covers often provide superior long-term value due to their durability and repeated usability. They are frequently used alongside shrink or stretch wrap to enhance protection for palletized goods.
Plastic pallet covers come with numerous advantages, some of which are highlighted below:
Although plastic pallet covers offer many benefits, there are certain drawbacks to consider:
Plastic pallet covers, also known as poly pallet covers or pallet wrap sheets, are essential materials handling solutions designed to safeguard goods during storage and transportation. In high-traffic warehouse environments, plastic pallet covers protect valuable inventory from dust, dirt, moisture, grease, and various environmental contaminants. Their robust construction helps ensure product integrity, maintain clean storage conditions, and extend the lifespan of goods. Below, we explore the most common industrial and commercial applications of plastic pallet covers:
Plastic pallet covers are highly effective for organizing merchandise on pallets within distribution centers, fulfillment facilities, and storage warehouses. By using color-coded or labeled plastic pallet covers, businesses can easily differentiate between product categories, sort seasonal stock, and streamline inventory control. This organization not only improves workflow efficiency but also reduces picking errors, saving valuable time during order processing and shipment preparation. Additionally, when used with stretch wrap or pallet bands, plastic pallet covers help consolidate multiple items, keeping product loads secure and intact throughout handling and logistics operations.
Serving as a critical barrier, plastic pallet covers provide a cost-effective solution for shielding goods from a range of environmental hazards, including moisture infiltration, UV radiation, wind, and rain during shipping or outdoor storage. These protective pallet covers prevent dust accumulation, dirt exposure, and potential contamination, ensuring that sensitive or high-value merchandise—such as electronics, pharmaceuticals, or food products—remains undamaged. For companies shipping goods via freight, bulk transport, or export containers, using heavy-duty and moisture-resistant plastic pallet covers is essential for maintaining product quality, meeting compliance regulations, and reducing risk of returns due to damage.
Custom-printed plastic pallet covers create opportunities for companies to enhance their brand visibility, improve product identification, and communicate critical handling instructions directly on the packaging. Available in a variety of sizes, colors, and thicknesses, these branded pallet covers can feature a company’s logo, contact information, barcodes, and compliance markings. Not only do custom pallet covers help distinguish products from competitors, but they also improve transparency and traceability as goods move through complex supply chains. This branding advantage is especially valuable for contract manufacturers, logistics providers, and distributors aiming to reinforce professional image and enhance customer satisfaction during the entire shipping process.
Gaylord containers, large corrugated boxes designed for bulk shipping, often require gusseted poly pallet covers for both internal lining and external protection. These gusseted plastic covers fit over stacked boxes or irregular loads, shielding goods from dust, spills, and moisture during transport or storage. By using plastic pallet covers with Gaylord containers, companies handling raw materials, recyclables, or bulk commodities can achieve maximum durability, efficiency, and cost savings. For industries such as agriculture, automotive, and manufacturing, these heavy-duty pallet covers simplify logistics by keeping shipments organized, secure, and compliant with shipping regulations.
In summary, plastic pallet covers are indispensable components for maintaining product safety, optimizing inventory management, and supporting supply chain efficiency. Whether you operate in manufacturing, warehousing, distribution, or retail, investing in high-quality plastic pallet covers can dramatically enhance protection, organization, and branding throughout your logistics operations.
There are various types of plastic pallet covers, each tailored to different products and their specific protection needs. Generally, plastic pallet covers are categorized into tarps, wraps, or covers. Below, we will explore these different types in more detail.
Shrink wrap, as the name suggests, shrinks to create a tight, protective seal around a package. This ensures that the items inside are safeguarded from external contaminants such as moisture, dust, and air. Additionally, because shrink wrap is transparent and largely waterproof, it allows for easy identification of goods while offering a degree of protection from environmental elements.
Unlike stretch wrap, which is stretched around the pallet, shrink wrap uses heat to shrink the plastic tightly around the merchandise. When heated, shrink wrap contracts, forming an airtight seal around the containers. However, determining the precise amount of shrink wrap needed to cover a pallet can be time-consuming and requires some experience.
Shrink-wrapping a pallet helps protect it from spills and dirt, and it makes metal items more resistant to rust. Additionally, this wrapping method secures the goods on the pallet, minimizing the risk of items shifting, falling off, or being stolen.
While shrink wrap offers many benefits, there are two key factors that might make you reconsider its use:
Stretch wrapping is a type of plastic wrap used for covering pallets, involving the wrapping of plastic material around boxes on a pallet by either a person or a machine. Stretch wrap can be categorized into blown stretch wrap and cast stretch wrap, depending on the production method. Blown stretch wrap is made by melting plastic, passing it through a die to form a thin-walled tube, then inflating it with air as it exits the die, resulting in layers of plastic wrap.
Blown stretch wrap creates a more durable film compared to cast stretch wrap, but it tends to be more opaque because the plastic crystallizes during the process, reducing the visibility of the wrapped items. Additionally, the thickness of blown stretch wrap can be less uniform due to the extra processing required. It is also more costly to produce, making it less commonly used than cast stretch wrap.
Cast stretch wrap is made by passing a heated resin through cold rollers to create a clear, translucent film. In this process, plastic is melted in a heated screw barrel and then extruded horizontally through a flat die. The thickness of the wrap is controlled by a slit in the die as the material exits. As the wrap emerges from the die, it is cooled by wrapping around a chilled roller to solidify.
A plastic pallet tarp cover is used to safeguard a package. Such pallet coverings can range from clear, throwaway covers to reusable, thermal covers and are often constructed of porous polyethylene. Such coverings are produced in various sizes in order to always protect a pallet’s contents. Most plastic pallet tarp covers also include an ultraviolet (UV) coating to shield perishable items like food from the sun.
Clear plastic pallet covers are suitable for use with pallets of goods stored both indoors and outdoors. They shield boxes from environmental elements such as dust and humidity, as well as other contaminants. Additionally, their transparency provides a clear view of the shipment’s contents, making it easy to identify items without removing the cover.
However, transparent pallet covers may not offer adequate UV protection for perishable items. Their clear nature can also make products more vulnerable to temperature fluctuations. Therefore, clear plastic pallet covers are most appropriate for short-term shipments involving perishable goods.
Black plastic tarps are effective at deterring theft by obscuring the contents of shipments. If the items are not visible, potential thieves are less likely to target the shipment. Moreover, many black pallet covers are treated with a UV coating to protect against direct sunlight. These covers also safeguard shipments from dirt, dust, and humidity, and offer resistance to minor spills and leaks.
Black poly materials are ideal for situations where shipments need to be concealed or require UV protection from the sun. Black plastic pallet covers come in a wide variety of thicknesses, allowing for customization based on specific needs. Additionally, these covers can be provided in rolls with perforations for easy and convenient dispensing.
Thermal plastic pallet covers are helpful for some products that need a controlled temperature. Thermal pallet covers can be useful for both heating and cooling applications, such as keeping a shipment chilly in the summer or warm in the winter. In addition, the items they cover are less likely to be stolen since thermal plastic pallets are opaque.
Pallet top sheets are plastic liners designed with perforated strips for easy dispensing and tearing from rolls. Like other plastic pallet covers, they protect products from contaminants such as dust, dirt, moisture, and grease commonly found in warehouses. However, pallet top sheets are specifically intended to cover individual layers of a pallet rather than the entire load. They not only shield shipments from external contaminants but also prevent leaks from cartons situated between layers. Pallet top sheets can be used on their own or in combination with other plastic pallet covers for added protection.
Pallet-size shrink bags are recommended for use with large machinery, heavy or irregular loads, and for outdoor protection. This type of shrink wrap comes as a gusseted bag on a perforated roll, allowing for easy peel-off. Designed to cover an entire pallet, these bags are heated with a heat gun to tightly secure the contents and provide a more secure enclosure.
Clear pallet-size shrink bags offer both transparency and durability for covering large pallet loads. While their transparency allows for easy visibility of the items, it also increases UV exposure, which can be a drawback if the items are transported or stored outside. These shrink bags are available in rolls of 25 and are made from thick 4 mil plastic, providing strength and stability to secure large loads effectively.
Gusseted black UVI (ultraviolet-inhibiting) pallet covers come on rolls and are pre-cut and perforated for easy dispensing. These covers help keep goods clean, dust-free, and protected from light. They are often used to cover machinery or to line Gaylord containers, safeguarding the contents from moisture and contamination. The black opaque film is particularly effective for outdoor storage, as it conceals the pallet’s contents, which helps deter theft and protects light-sensitive items. Made from durable polyethylene, these covers offer cost-effective protection, with pleated sides that accommodate the width of most standard pallets.
Vented pallet wrap is designed to let moisture and condensation escape, making it ideal for frozen or cold storage applications. This type of wrap is lighter than traditional stretch film, which helps reduce shipping costs. Additionally, the vents facilitate easier handling during use, enhancing overall efficiency.
Pallet cover bags ensure that bin and box contents remain secure and protected from moisture, dirt, and abrasion. Made from durable and transparent materials, these bags are built to last and provide easy visibility for inspecting the contents. They are available in various sizes and gauge thicknesses to meet different protective requirements.
Poly tarps feature loosely-woven polyethylene strips laminated to polyethylene sheets. In addition to protecting items from airborne contaminants, poly tarps are waterproof and offer excellent protection from precipitation. This material also resists stretching which increases its durability. When UV-coated, poly tarps may provide protection from the sun for years. Poly tarps are available in various colors; clear poly tarps are also available. Poly tarps also come in numerous mil thicknesses.
Poly top sheets are designed to offer additional protection for individual layers of boxes stacked on a pallet. They help maintain the integrity of stored goods by shielding them from mud, dust, moisture, bacteria, and fungi. These top sheets comply with FDA guidelines for covering food items and are available in various sizes to fit different box dimensions. Standard sizes range from 60" x 60" to 75" x 75", and they come in a variety of thicknesses to suit different needs.
Pallets come in various sizes and shapes, which can make selecting the right pallet wrapping options challenging. It’s important to choose a plastic pallet cover that fits snugly over the pallet and its contents. To ensure you select the correct size, measure the shipment carefully. Use the following formula to determine the size of the pallet cover required:
Start by measuring the pallet's width (W), depth (D) (or length), and height (H). Then, increase the width by approximately four inches. To calculate the height needed for the pallet cover, divide the adjusted width by two and add it to the measured height. An example of this measurement formula is provided below.
W: 46 inches + 4 inches = 50 inches
D: 49 inches
H: 50 inches + 25 inches (half the width) = 75 inches
The additional four inches added to the width can be adjusted based on how snugly the cover needs to fit. For a tighter fit, you might use a two-inch addition instead of four inches.
For example, if the pallet measures 46 inches wide, 49 inches deep, and 50 inches long, the required dimensions for the pallet cover would be 50 inches x 49 inches x 75 inches.
While there are no strict guidelines for pallet wrapping, the following sequence is commonly used:
When using plastic pallet covers to protect boxes on pallets, the following steps are typically followed:
Plastic pallet covers are versatile and offer excellent ventilation for goods. They are also cost-effective for packaging and shipping pallets of products. Below are some industrial applications for plastic pallet covers:
Plastic pallet covers come in thicknesses ranging from 1 mil to 4 mils. Covers rated at 1 mil are typically used for short-term protection of palletized goods. Thicker covers, such as those rated at 4 mils, provide enhanced protection and are often used as reusable covers for frequent handling of palletized items. For loads without sharp edges that don’t require high resistance to tears and punctures, 1 mil clear pallet covers are ideal. Covers with a thickness of 1.5 mils offer good dust and moisture protection while being cost-effective. A 2 mil thickness is slightly sturdier, suitable for most warehouse tasks, and provides protection against moisture, paint, dust, and is resistant to tearing. For use as container liners or for covering machinery, 3 mil polypropylene covers are highly effective. The thickest option, 4 mil covers, offer excellent tear resistance and are recommended for loads with sharp or potentially hazardous edges.
Plastic tarps and covers, though serving similar functions, differ in several aspects such as their application, material weight, thickness, and durability. Tarps are typically reusable, made from thick, heavy-duty plastic designed for repeated use, unlike shrink wrap, which is intended for single use and removed once a shipment reaches its destination.
Lightweight plastic covers are thin and designed for single-use shipments or minimal warehouse protection. They offer sufficient coverage for short-haul deliveries and help keep loads secure. In warehouses, lightweight plastic pallet covers protect against dirt, dust, and debris, providing minimal water resistance and shielding products during movement.
Historically, tarps, or tarpaulins, were made from materials like canvas, burlap, and cotton. With the advent of plastic fabrics, tarps have become more resilient, reliable, and durable. Canvas tarps have largely been replaced by vinyl and plastic tarps due to the higher cost of canvas, although they are still used in military and heavy industrial applications.
Modern tarps are made from various materials, including:
Polyethylene: Polyethylene tarps are made of a thermoplastic polymer that is resistant to moisture, UV radiation, and mildew. High density (HDPE) or low density (LDPE) polyethylene are used to make them, which can be light duty or heavy duty.
Light duty poly tarps are lighter in weight, have a low poly coating, and lower mesh count. They are not as resilient or strong as heavy poly tarps and are designed for short term use.
High duty poly tarps are heavier, have a thicker poly coating, and high mesh count. They are long lasting and made of high quality materials.
Polyvinyl Chloride (PVC): PVC tarps are made of a vinyl coated polyester fabric that is resistant to tearing, abrasion, and UV radiation and are used for heavy duty applications. They are exceptionally durable, can withstand extreme weather conditions, have high strength, and are used for harsh stressful applications.
When compared to other forms of plastic pallet covers, PVC pallet covers are thicker and resistant to mildew, grease, and acids. They are designed and configured to face the most hazardous and high duty purposes.
While plastic pollution is a significant environmental issue, many plastics used in plastic pallet covers are recyclable and can be repurposed at the end of their useful life. These plastics are categorized as post-consumer recycled content (PCR) and post-industrial recycled content (PIR), both of which are used to manufacture new plastic pallet covers.
The plastic pallet cover industry is committed to minimizing environmental impact by focusing on recycling and ensuring that their products are not disposed of in landfills. Their ongoing efforts are aimed at promoting the sustainability of their products and reducing waste.
Pallet covers come in a variety of sizes and thicknesses and can be custom-made to fit any specific application.
Plastic Pallet Covers Thickness: Available in thicknesses from 1 mil to 4 mil, plastic pallet covers offer varying levels of protection. 1 mil covers are suitable for temporary protection, while 4 mil covers provide excellent tear resistance and can be reused multiple times to cover and uncover palletized items.
Custom Printing on Plastic Pallet Covers: Plastic pallet covers can be custom printed with logos or any other required information to meet user specifications.
The primary differences between pallet covers and pallet tarps are the materials used, the durability, and the cost.
Materials Used in Covers & Tarps: Pallet covers are often made from low-density polyethylene (LDPE), which is a more affordable option. In contrast, pallet tarps are typically made from durable woven polyester, which offers a longer lifespan.
Durability: Factors such as UV exposure, moisture, and extreme temperatures can impact the durability of both woven polyester and LDPE. Adding UV blockers to LDPE can extend its lifespan. Generally, plastic pallet covers can provide effective dust protection for several years when used in controlled environments.
Cost: Plastic pallet covers are cost-effective as they are reusable and can last nearly as long as woven polyester tarps when used correctly.
Choosing Between Clear and Black UVI Pallet Covers: Black UV-resistant pallet covers are ideal for products that will be stored outside for extended periods and need protection from sunlight. For other uses, clear or standard black pallet covers may be sufficient.
Water-Resistance: Like all polyethylene bags, these plastic pallet cover bags are water-resistant but not waterproof. They can protect products during quick transport but should not be used to leave items outside overnight if they can be damaged by water.
Reasons for Using Pallet Top Sheets: Plastic pallet covers and pallet shrink bags are used to protect the contents of an entire pallet. Pallet top sheets can be used alone or in conjunction with pallet covers or bags. They serve several purposes, including separating stacked layers on a pallet. For example, if a pallet is stacked with boxes of ink pens on top of boxes of paper, a top sheet can prevent ink from leaking onto the paper below. Additionally, top sheets provide temporary protection from moisture, dust, dirt, and grease when the pallet is stored.
Plastic pallet covers are ideal for a lot of uses. They are available in a wide selection and variety and can aid in safely storing goods for work or play. Plastic pallet covers require a considerable initial investment, but their ability to protect expensive items from damage and their potential for reuse more than justify this cost.
