Stretch Wrap
Blown stretch wrap films are typically used for heavier irregular loads (most commonly pallet wrapping) and applications requiring stretch film with excellent puncture and tear resistance.
Additives are used to provide excellent cling and load stabalisation characteristics, as a result, blown stretch films can be noisy as reels are unwound.
The main difference between the core sizes is: Extended core means that the core is longer and provides better grip whilst wrapping the pallet. Standard cores mean that the core appears slightly from the roll, but not as much as the extended. Please see the individual products for their measurements and images.
A quick indicator to identify blown film is that it is sticky on both sides.
