BOPE is the abbreviation of Biaxially Oriented Polyethylene, that is, biaxially oriented polyethylene film. It is made of special LLDPE and HDPE raw materials, which are stretched longitudinally and then transversely. Compared with production by blow molding (IPE) or casting method (CPE) polyethylene film.
There is a significant improvement in physical properties. BOPE film has high transparency, stronger mechanical strength and one-way easy tearing.
Compared with traditional PE film, the puncture resistance is improved, especially in the application of low-temperature frozen packaging products. In terms of performance, it can significantly reduce the rate of package breakage during transportation and display.
At the same time, the product has more outstanding thickness uniformity, heat sealing performance, good moisture resistance, good longitudinal and transverse tensile strength, and has the advantages of moisture resistance and foldability.
Biaxially oriented polyethylene film (bope film) is processed and formed by flat film biaxial stretching process, with large stretching ratio and high production efficiency. The film has excellent mechanical strength, optical properties, heat sealability, water resistance, water resistance and breathability It is an ideal packaging material and is widely used in the packaging of food, fruits and vegetables, baby products, etc., and occupies a very important position in the market.
Its advantages are as follows:
1. Replacing blown or cast CPE film with half thickness BOPE and dry compounding with BOPA or BOPET can achieve the same heat sealing strength and similar stiffness.
2. Using half-thickness BOPE instead of blow molding or cast CPE film and BOPA dry compounding for freezing packaging at -18°C can greatly reduce the bag breakage rate.
Its application is: instead of blow molding and casting PE film and BOPA or BOPET and aluminum foil dry or extrusion compound bag making, or single-layer fusion sealing bag making, or coating, or compound PE film, etc., used for various Packaging for food or daily necessities, etc.
