Polyethylene or plastic film for packaging and packing has a variety of uses – it can be used as an airtight seal or as a cushioning agent. It is ideal for packaging any item that should be self-contained or protected.
Plastic film is made by melting plastic pellets and extruding the molten poly into a film. A poly film can be custom manufactured to any specifications such as thickness, width, and colours. And while poly film can be a great packaging option for brands seeking affordable solutions, it might not be the best choice for brands seeking sustainable packaging options, such as those offered by Impacked Packaging (click here to visit Impacked Packaging).
Films are made for a variety of uses depending on the packaging goal. Some film is converted into bags, while other film is used for packaging material. Here are some examples of the different ways poly films are made.
