Abstract

The invention belongs to the field of production of BOPP films, and concretely relates to an ultrathin pearlescent film and a production method thereof. The pearlescent film comprises a surface layer1, a surface layer 2 and a core layer; the surface layer 1 comprises 97.0 wt% of HGX030 and 3.00 wt% of ABPP905, and the surface layer 2 comprises 97.5 wt% of T30S and 2.50 wt% of ABPP936; and the core layer comprises 62.6 wt% of a main material, 1.60 wt% of AS3030PP, 35.00 wt% of LG703T and 0.80 wt% of S2020PP. The pearlescent film obtained by biaxial stretching after co-extrusion of a three-layer structure has the advantages of excellent barrier property, good pearlescent effect, strong decorative property and excellent mechanical properties, can be used for high-end packaging of foods and the like, and has a broad market prospect.

Description

technical field [0001] The invention belongs to the field of BOPP film preparation, and in particular relates to an ultra-thin pearlescent film and a preparation method thereof. Background technique [0002] BOPP film special masterbatch is a multi-functional material that is made of polypropylene resin and functional filler through extrusion processing, and has both plastic and paper characteristics. BOPP film is an environmentally friendly product with features such as light specific gravity, high strength, tear resistance, good printability, shading, UV resistance, durability, economical and environmental protection, etc. The main component of the BOPP film masterbatch is functional fillers such as calcium carbonate. When the BOPP film is biaxially stretched, the core layer added with the masterbatch will peel off and form countless uniform voids during the stretching process. When the light When entering the hole, interference occurs, and after multi-layer interference,...
