PET longitudinal stretch film machine

Stretch film is developed from single-layer to two-layer and three-layer, and now the stretch film produced by casting method is the main one, and the early stretch film is mostly blown film, which is because the production of casting line has the advantages of uniformity in thickness, transparency, etc., and it can be applied to the requirements of high rate pre-stretching. Stretch film produced by casting method has high transparency, high elongation, puncture strength and tear strength.

Stretch film has a wide range of applications, is widely used in hardware, minerals, chemicals, pharmaceuticals, food, machinery and other products on the whole set of packaging. With good heat sealing performance and excellent transparency, cast film is one of the main packaging composite substrates, used in the production of high temperature cooking film, vacuum aluminised film, etc. MDO one-way stretch film production line PET PPPEPA cast film production line:Among them, there are two kinds of longitudinal stretching machines, vertical and horizontal. Horizontal structure is easy to expand and easy to lead film, more suitable for pilot and small-scale production. Vertical structure covers a small area, more suitable for laboratory use.
