When people buy some items, especially some fine, fragile items, the box will have a layer of air cushion film to buffer. Many people prefer boring when squeezing air bubbles on the cushion film to release the pressure. So how to air-cushion film extrusion it?

 (1) Raw material selection Air cushion film extrusion is the main raw material of low-density polyethylene, high-density polyethylene, linear polyethylene, if the air cushion film requires a color, the resin should be added to the amount of coloring agent. Anti-static bubble film from low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) to add anti-static agent by blowing bubbles.

(2) Equipment selection As the air cushion film extrusion raw materials are mainly low-density polyethylene, high-density polyethylene, linear polyethylene, extrusion molding only PE material extrusion with a general-purpose extruder can be. Molding mold structure should be based on extrusion film production mode decision. Air-cushion film molding can be blow molding, can also choose flat film forming method, extrusion molding flat film production process is relatively simple.

(3) low-density polyethylene bubble film, high-density polyethylene bubble film, linear polyethylene bubble film quality standards should be consistent with

ISO9001: 2008,

ROHS

SGS quality certification
