Problems solved by technology

[0002] Ordinary BOPE optical film has the advantages of high light transmission, high strength, and good flatness. However, with the development of society, ordinary BOPE optical film can no longer meet the needs of consumers.
If the existing BOPE film wants to achieve a better heat sealing effect, it needs to use composite heat sealing materials in the later stage, which increases the cost

Abstract

The invention relates to a biaxially-oriented BOPE film and a preparation method thereof. The biaxially-oriented BOPE film comprises a surface layer I, a core layer and a surface layer II, wherein thecore layer is located between the surface layer I and the surface layer II; the surface layer I is composed of a heat sealing material and an anti-sticking agent; the surface layer II is composed ofpolyethylene and an anti-sticking agent; and the core layer is made of polyethylene and an antistatic agent. Raw materials for the three layers are respectively subjected to extrusion, strip casting,longitudinal stretching, transverse stretching, traction, corona treatment and rolling after melt plastification so as to obtain a product, namely the biaxially-oriented BOPE film. According to the film, the novel heat-sealing material is used on the surface layer I, so the heat-sealing temperature of the film is reduced to a very low temperature, the secondary composite processing of downstream customers is reduced, and wasting is reduced. According to a detection result, the product has heat sealing performance at 92 DEG C; the heat sealing strength of the film can reach 8.9 N / mm at 95 DEG C; and the film is very suitable for printing and compounding through corona treatment.
