Embodiment 1

[0033] A tactile primerless BOPP pre-coated base film, the film is composed of an upper surface layer, an adhesive layer, a middle core layer and an EVA composite layer.

[0034] The upper surface layer is the tactile layer, which is composed of thermoplastic polyester polyurethane elastomer rubber (TPU) 25%, special anti-scratch additive 3% and homopolypropylene 72%. Among them, the special anti-scratch additive is compounded by copolymerized polypropylene, 10-20% of fast-migrating smooth agent and 10-20% of anti-scratch agent. The fast-migrating slip agent is erucamide and fat A compound mixture of amide, wherein the mass ratio of erucamide is 20-40%; the anti-scratch agent is a compound mixture of silicon dioxide and low molecular weight siloxane, wherein the mass ratio of silicon dioxide is 40wt%, The mass ratio of low molecular weight siloxane is 60wt%.

[0035] The tie layer is composed of 100% maleic anhydride grafted polypropylene.

[0036] The middle core layer is c...

Abstract

The invention discloses a tactility-type non-primer BOPP pre-coating basement membrane and a preparation method thereof. The membrane is composed of a top surface layer, a bonding layer, a middle core layer and a bottom surface layer in sequence from top to bottom, the top surface layer is a tactility layer, the bonding layer is made from maleic anhydride grafted polypropylene, the middle core layer is a polypropylene layer, and the bottom surface layer is an EVA composite layer. According to the membrane, tactility resin, a special scuffing-resistant additive are subjected to directly participate in co-extruding two-way stretching film formation of polypropylene, subsequent coating processing is excluded, the equipment input of a coater is reduced, solvent evaporation in a coating process is avoided at the same time, and advantage of energy consumption and pollution reducing is provided. The tactility-type non-primer BOPP pre-coating basement membrane has the advantages that the haze is even, the light transmission, tensile strength and elongation at a break all meet national standard requirements; the tactility surface has the property of velvet-like hand feeling, and the surface scuffing-resistant performance is good when the basement membrane is produced or used.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to a tactile-type primerless BOPP pre-coated base film and a preparation method thereof. technical background [0002] Tactile film is a matte film with special tactile properties on the surface. It is generally used in the packaging of high-end luxury goods through paper-plastic composite. The tactile properties of the tactile film include silk-like velvet feel and scratch resistance during production or use. [0003] The surface of ordinary plastic film is relatively hard, giving people a very stiff touch. There is a layer of special material on the surface of the tactile film, so it has its special surface properties. At present, the tactile film is mainly realized by coating, which belongs to the follow-up processing of BOPP products, and the investment in equipment is high, and there are problems such as solvent pollution and energy consumption in the coating process.
