Transparent Plain LDPE Heat Shrink Film, Packaging Type : Roll

The Benefits of LDPE HEAT Shrink Film

• Film shrink is allows manufacturers to wrap their packaging tightly around the product.
• Waste Reduction. 
• Reduces shipping cost .
• Tailor made sizes and Thicknesses. 
• Different Types of Wraps.

Polyethylene is the mostly used material for shrink film applications. LDPE (low density polyethylene) is the widely consumed type of material for secondary and tertiary packaging due to its advantages and specific properties.

Film shrink is what allows manufacturers to wrap their packaging tightly around the product. They place the polyethylene (PE) material loosely around the item or items and apply heat. The PE shrinks around it for a tight fit that conforms to the item. Different types of shrink material vary in characteristics of durability, stretchability and thickness, allowing users to find the right one for their work.

There are many benefits of LDPE shrink wrap for packaging. It has a low melting point and great durability and thickness, making it particularly useful for wrapping materials, including heavier items and food products. It has approval from the Food and Drug Administration (FDA), so it’s commonly used in wrapping certain food items. It also doesn’t have many of the drawbacks that come with alternative shrink-wrapping materials such as polyvinyl chloride (PVC) and polyolefin (POF).

The manufacturing process of LDPE film allows the shrink potential around a product to be between 40% and 60% in the machine direction, or length of the film, and 5% to 15% in the transverse direction, or width of the film. Shrinkage occurs when the film absorbs energy, typically through the form of heat energy, causing the molecule chains to return to a more natural arrangement. The film casts to the product, creating a tight unitized pack.

Shrinking the film to the product provides additional shipping, palletizing and handling benefits compared to unitizing and packaging products within a corrugated box.

Shrink bundling products in LDPE film can minimize the overall size and weight of a package, resulting in lower shipping costs
