Blown Stretch Film vs Cast Stretch Film Explained

Video Transcript

Hey everyone. Ricky Chu from Chu’s Packaging Supplies. Today I want to talk about the differences between blown stretch film and cast stretch film. Both are used to wrap pallets, but each has its own characteristics. I have two rolls here, side by side. This one is blown. This one is cast. As you can see, if you look closely, the blown is a little milkier and more translucent in color and a lot stickier.

I don’t know if you can hear that.

Cast stretch film over here. It’s much more clear, more crystal-like and a lot quieter when you unwrap it.

Both are very durable, but blown stretch film is much more puncture resistant. So if you have uneven pallets, or you have sharp objects like metal or wood then blown stretch film is the way to go. One thing to keep in mind though, is because of the process to produce blown stretch film it is slightly more expensive than the cast film.
