The five layer co extrusion blown film unit is mainly suitable for resins with gas barrier properties such as HDPE, MHDPE LDPE LLDPE MLLDPE PA EVOH, etc. The produced film is mainly used as packaging materials for heavy packaging, high-end food bags, vacuum packaging bags, liquid packaging bags, etc., to achieve the packaging purpose of fragrance preservation, anti-corrosion, airtightness, and extended shelf life.
The adjustment range of the five layer material formula is more flexible, with stronger puncture resistance, higher tensile ratio, more uniform thickness, higher yield, and more advantageous film cost-effectiveness. By using multi-layer co extrusion plane overlay die heads, IBC internal cooling system, upward rotation traction, and automatic winding technology, the products have good barrier performance and heat sealing performance。
