Problems solved by technology

However, why there is no CPP matting film supply market, our investigation found that
Regarding CPP matting film, one is that there is no CPP matting film production technology, and the other is that the matting masterbatch for CPP has not been developed, and of course there will be no CPP matting film

Embodiment Construction

[0015] 1. An all-polymer CPP matting film, prepared by casting A, B, and C three-layer raw materials, wherein A layer is the matting surface layer, B layer is the core layer, and C layer is the bottom layer. It is characterized in that : The weight ratio of the raw material components of each layer is: A layer: 100% all-polymer matting masterbatch; B layer: polypropylene 97~98%, antistatic agent 2.0~3.0%; C layer: polypropylene 95~ 97%, anti-adhesive agent 3.0~5.0%, the thickness of each layer is: A layer: 5~6μm; B layer: 10~25μm; C layer: 4~5μm.

[0016] In this embodiment, the composition of the all-polymer matting masterbatch includes: polypropylene 25-35%; random polypropylene-ethylene copolymer 30-40%; linear low-density polyethylene 30-45%. The antistatic agent is AY088 antistatic agent, and the anti-adhesive agent is AB801 anti-adhesive agent.

[0017] Among them: AB801 anti-adhesive agent and AY088 antistatic agent are common models in this industry, and the products ...

Abstract

The invention relates to a polypropylene matt film, particularly to a matt film, namely a CPP (cast polypropylene) matt film, prepared from mixture type matt master batch completely consisting of high polymers by using a casting method. The CPP matt film is prepared from there layers of raw materials by using the casting method, wherein the layer A is a matt surface layer, the layer B is a core layer, and the layer C is a bottom layer; and the matt film is characterized in that each layer comprises the following compositions in percentage by weight: the layer A: 100% of all-polymer master matt materials; the layer B: 97-98% of polypropylene, and 2.0-3.0% of antistatic agents; and the layer C: 95-97% of polypropylene, and 3.0-5.0% of caking inhibiters. The all-polymer matt master batch comprises the following compositions in percentage by weight: 25-35% of polypropylene, 30-40% of random polypropylene-ethylene copolymer, and 30-45% of linear low-density polyethylene. The CPP matt film provided by the invention not only has the matt performance of the existing BOPP (biaxially-oriented polypropylene) matt film, but also has the advantages of good flexibility, puncture resistance, good tear-resistant performance, and the like as compared with the BOPP matt film.

Description

technical field [0001] The invention relates to a polypropylene matting film, in particular to a matting film made of a mixture-type matting masterbatch entirely composed of high molecular polymers through a casting method——CPP matting film. Background technique [0002] The advent of BOPP matting film has brought a powerful impact on people's traditional aesthetics. Those plastic film products or other printed materials that are printed colorfully and sparkle brightly and dazzlingly give people an unreal feeling. Commonly known as "dazzling", but after the surface of these printed matter is covered with a layer of matting film, the printed pattern becomes soft, quiet, elegant, and the color is reproduced vividly, highlighting the beauty of natural luster. In addition, the matting film surface has a very comfortable feeling The hand feel makes the packaged objects more noble and strongly attracts the attention of viewers or consumers. [0003] The BOPP matting film is made ...
