Shrink film is widely used around the world, it helps packing products more conveniently. This makes it possible to pack larger quantities of products and deliver more products per time, and it reduces shipping costs for the suppliers.

Shrink film can be made of several types of materials. The most common ones on the market today are polyvinyl chloride (PVC), polyolefin (POF), and polyethylene (PE).

As for PE, there are 3 different forms which include Low-Density Polyethylene (LDPE), Linear Low-Density Polyethylene (LLDPE), and High-Density Polyethylene (HDPE).

For shrink film application, LDPE would be the best choice, as it has higher strength and more durability for heavier items.

Key Benefits of LDPE shrink film

There are many benefits of LDPE shrink film for packaging. It has a low melting point and great durability, making it particularly useful for wrapping your final products, such as water bottles and food products.

LDPE shrink film is also printable and can have excellent graphics added while still maintaining the image and the strength required. It also does not have many of the drawbacks of alternative shrink wrap materials such as PVC and POF.

Therefore, using LDPE to produce shrink film is one of the most popular ways among shrink film producers today.

Further advantages of LDPE shrink films:
  1. Good visibility of the film, making it easy to recognize the product inside.
  2. Protecting the environment since LDPE shrink film is 100% recyclable.
  3. LDPE film can easily be blended with various chemical additives or other film materials to enhance the original properties.
