Stretch film is one of the most preferred methods for packaging different types of products and goods. But do you know the difference between cast, blown and pre-stretch film?
At PACKIN, we will explain what these three types of stretch film are and how they can be used. We hope our professional advice will be useful for your business.
Cast Stretch Film
Cast stretch film is a transparent stretch film that allows the packaged products to remain clearly visible. It stretches easily and has natural cling on both sides, allowing it to adhere both to the products and to itself.
However, its easy stretchability comes at the expense of strength, and it can tear more easily. Considering its advantages and disadvantages, cast stretch film is significantly cheaper than blown stretch film and is used on a much larger scale.
Blown Stretch Film
This type of stretch film is much stronger than the others. It is resistant to punctures and tearing, which makes it especially suitable for transporting loads with sharp edges.
Blown stretch film can stretch and recover its length, which ensures much stronger packaging for the products. One disadvantage is that it is not completely transparent, making it more difficult to see the packaged goods.
Because of its higher density and strength, the price of blown stretch film is naturally higher.
Pre-Stretch Film
Pre-stretch film is positioned between cast and blown film in terms of properties. It is thinner than traditional blown film, but still offers very high strength.
It stretches relatively easily and recovers its length after stretching. With pre-stretch film, packaging is fast and easy.
One of its main advantages is the lower cost per package, which can help your business save significant packaging costs.
