Problems solved by technology

According to this method, the production of BOPA matting film needs to be divided into two steps. First, the ordinary BOPA film is produced, and then the matting material is applied to the surface of the BOPA film with a coating machine to achieve the purpose of matting. However, the production process of this method is cumbersome and the output is low. Increased investment cost and production cost
Moreover, if the amount of matting material applied to the surface of the film is insufficient, the desired matting effect cannot be obtained.

Abstract

The invention provides a BOPA matt film, which has a three-layer structure consisting of a surface layer, a core layer and a matt layer, wherein the surface layer comprises 0 to 1 weight percent of antiblocking agent, 0 to 1 weight percent of slipping agent and the balance of nylon-6 resin; the core layer is nylon-6 resin; the matt layer comprises 98.5 to 100 weight percent of matt material and 0 to 1.5 weight percent of slipping agent; and the three-layer structure of the BOPA matt film is formed by extrusion and bidirectional drawing. The invention also provides a method for manufacturing the BOPA matt film.

Description

Technical field: [0001] The invention relates to a matting film and a manufacturing method thereof, in particular to a biaxially stretched nylon matting film (BOPA matting film for short) and a manufacturing method thereof. Background technique: [0002] BOPA matting film is a fashionable and high-grade composite and packaging material, which can give people a soft, comfortable and hazy visual effect. After being stimulated by sunlight and screens for a long time, people can eliminate eye fatigue when watching books, pictures, color-printed pictures and packaging compounded with matting film. Moreover, BOPA matting film can be used in food packaging (biscuits, dried fruits, tea, cakes, etc.) after compounding to create an image of a natural product. Corona matting film is suitable for printing, lamination, low-temperature bronzing, etc. It is laminated with paper or other substrates after being glued on the glossy surface. It is usually used for surface lamination of books...
