What are the characteristics of biaxially stretched pe film?

2020-08-10

The biaxially oriented PE film is a newly developed PE film. It is a film produced with a special LLDPE raw material, similar to the BOPP production line, using a flat film biaxial orientation stepwise stretching process. BOPE film has the characteristics of high transparency, stronger mechanical strength and one-way easy tearing. Compared with traditional PE film, the puncture resistance performance has been improved. Especially in the application of low-temperature frozen packaging products, it can significantly reduce the transportation and display process. Rate of broken packets in The product also has more outstanding thickness uniformity, heat sealability, good moisture resistance, good longitudinal and transverse tensile strength, and has the advantages of moisture resistance and foldability.
The characteristics of biaxially stretched pe film are: high transparency, high gloss, few crystal points, high stiffness, high tensile strength, high heat sealing strength, high puncture resistance, excellent low temperature impact strength and pinhole resistance , Wear resistance, excellent low temperature flexibility, long wetting tension retention time, good printing performance, good thickness uniformity, accurate overprinting, water bath, density: 0.924-0.929g/cm3.
Biaxially oriented pe film replaces blown or cast CPE film with half the thickness of BOPE and BOPA or BOPET dry composite to achieve the same heat sealing strength and close stiffness. At the same time, replacing blow-molded or cast CPE film with BOPA and other dry composites with half thickness of BOPE for frozen packaging at -18°C can greatly reduce the rate of bag breakage.
Biaxially oriented pe film replaces blown and cast PE film and BOPA or BOPET and aluminum foil and other dry or extruded composite bags, or single-layer melt-sealed bags, or coating, or composite PE films, etc. Kind of packaging for food or daily necessities. OPE film can be used to replace traditional polyethylene film to reduce the amount of plastic, and it can also replace other polymers such as biaxially oriented nylon (BOPA) for packaging toughness. The biaxially oriented polyethylene (BOPE) film can also be directly used for the packaging printing layer. It is matched with the traditional polyethylene heat-seal layer to realize a full polyethylene packaging structure, which is more conducive to recycling and a more sustainable and environmentally friendly solution.
