Product Description
1. Basic concept of product
Stretch wrap or stretch film is a highly stretchable plastic film that is wrapped around items. The elastic recovery keeps the items tightly bound.It is frequently used to unitize pallet loads but also may be used for bundling smaller items.
Types of stretch film include bundling stretch film, hand stretch film, extended core stretch film, machine stretch film and static dissipative film.
2.Materials
The most common stretch wrap material is linear low-density polyethylene or LLDPE.
3. Advantage
1) Protects the packed items from abrasion & scratches
2) Even thickness, excellent clarity
3) Ease of removal
4) Saving cost and handling time
5) Ensuring stability of palletized goods during transportation
6) Environmental protection, non-toxic
7) Great ideals for protecting goods from moisture ,rust and dirt
