How cast stretch film is made?

Cast stretch film is a highly elastic plastic film used to wrap products for transportation and storage. It is frequently used in a commercial context to combine pallet loads but also may be used for bundling smaller items together. Cast stretch film comes in varying colours and can be used in numerous applications.

What is cast stretch film made of?

The most common cast stretch wrap material is linear low-density polyethylene. This material offers enhanced stretch film characteristics, particularly when it comes to elasticity and puncture resistance.

How is cast stretch film made?

Cast stretch film, or cast stretch wrap as it is also known, is created by feeding a sheet of heated resin along chilled rollers. As the molten resin comes in contact with the cooling drum, it solidifies. The resulting layer of plastic film is then cut and rolled into reams of cast stretch film. This process allows the film to be made in multiple layers, with cling on only one side. The end product is a strong, flexible film wrap that has a clear, glossy finish.

What are the benefits of using cast stretch film?

There are a number of benefits associated with cast stretch film. These include:

  • The clear, glossy finish ensures you are able to identify the product without having to unwarp it.
  • It also allows RFID and other scanning technology to be used through the packaging.
  • The optional one-sided-cling film is great where you don’t want one pallet to stick to the one next to it.
  • The cooling process is quick and can be produced in an hour with a lower cost in comparison to blown stretch film.
  • It is also easier to stretch and control the gauge to ensure consistent thickness control.
  • Cast stretch film can be made stronger by adding tough layers to the inside.
  • Cast film also unwinds much more quietly than blown film
