Stretch films are produced by either the cast coextrusion or the blown mono or coextrusion process. Over 85% of pallet stretch film volume in Europe is produced by the cast process. The advantages of cast over blown film for pallet stretch wrap include its superior appearance—high clarity and gloss, enhanced stiffness, low noise on unwind and superior gauge control. Blown films are generally less transparent and less glossy than cast films but, gauge for gauge, have superior puncture resistance and good force-to-load holding power. Stretch films, both cast and blown, are commonly produced using linear low density polyethylene resins: C4 (butene copolymers), C6 (hexene copolymers) C8 (octene copolymers) and metallocene hexene linear resins.
We have a large selection of pallet wrap available in stock.
Length, weight, pricing and packaging
The roll length of machine stretch films varies depending on the film thickness. Usual roll lengths are 1500 m, 1570 m, 1600 m, up to 3000 m. Thanks to the control we have on the manufacturing process, Pack-Bridge can always guarantee the quality and the measurement of the rolls: if you order 300 m rolls, you will receive exactly as promised, not 275 m rolls, as is often the case within the market. We always provide all specs of the film including weight, length, thickness etc.
