  • Publication number: 20090131618
    Abstract: A pre-stretched film roll of a mono orientated linear low density polyethylene (LLDPE) is stretched between 30% and 320% from it's original length depending on the final product that is required. Stretching is in the machine direction (MD) at a controlled rate in two stages. Differentially rewinding the film entraps air between the layers of the roll and creates soft overlapping edges around the roll to produce a spongy, soft roll that prevents and resists drop damage due to its shock absorbent characteristic.
