Product Introduction

Product Details

A 7-layer blown film machine is a device used in the manufacturing process of plastic films typically used in packaging or wrapping materials. It is called a 7-layer machine because it has seven separate layers of plastic material that are blown and fused together to produce a single film. The machine works by melting the plastic pellets and then extruding them through a die head. The extruded plastic is then blown up like a bubble and slowly cooled with air to produce a thin, uniform plastic film.

The cylinder and the screw stems of the above extruders are made of high quality alloy steel with optimum hardness and strong

corrosion resistance which after precision accomplishment and nitrogen treatment.The auxiliary machine has a platform working table for making operation easy.The coiling unit adopts torque motor to keep proper tension and make rolling even regular and roll-changing easy.

Use:

It is used to blowing various of LDPE thermal shrinking film and HDPE film rolls which are applied extensively to food, Medicine,

beer bottle, material bottle, box, case, cloth reel, floor, glass, all sizes of trays, pottery, tissue, etc.
