PE Wrapping Film Production Line
Knowledge Need to Know
1.PE wrapping film is divided into two kinds according to different application which is manual and machine use. Thickness of manual use is 15μ-20μ; machine use is 20μ-30μ
2.There are three kinds of wrapping film according to different packing method: manual stretching film, damping stretching film and pre-stretching film.
3.PE wrapping film is developed from single layer to double layers, three layers according to market needs.
4.At present the tape casting method is used to manufacture LLDPE stretching film because the film produced by tape casting method has advantages as even thickness, high transparent etc which is able to fulfill high magnification stretch requirements of customers.
5.High quality wrapping film has the features of high transparent, high longitudinal stretching magnification, high yield point, high horizontal tearing strength and good anti pierce performance.
