Problems solved by technology

In recent years, due to the impact of the international environment, the price of BOPET has risen to about 30,000 yuan / ton, and the delivery time is long, which greatly increases the cost of manufacturers. Therefore, it is urgent to develop a new type of transfer film to replace BOPET film
[0003] In recent years, matte film (usually called matte film in the BOPP industry) has been widely used in printing and lamination due to its high haze and low gloss. Because of its rigidity and thermal shrinkage rate, it is not as good as BOPET film, so it is still not suitable for leather transfer. Difficult to apply

Abstract

The invention relates to a matte BOPP (Biaxially-oriented Polypropylene) film for leather transferring and a preparation method thereof. The matte BOPP film consists of an inner surface layer, a core layer and an outer surface layer, and is prepared by coextrusion and two-way stretching of the inner surface layer, the core layer and the outer surface, wherein the inner surface layer comprises the following components in percentage by weight: 97.5-98.5% of polypropylene and 1.5-2.5% of adhesive; the core layer comprises the following components in percentage by weight: 98.0-98.4% of polypropylene, 1.0-1.2% of antistatic agent and 0.4-1.0% of slipping agent; the outer surface layer adopts a delustering material which comprises the following components in percentage by weight: 54-56% of polyethylene, 43.7-45.7% of high-density polyethylene and 0.3% of antioxidant. The matte BOPP film and the preparation method have the advantages that the selection and matching of the materials are reasonable, the selected polypropylene material is good in processing performance and high in mechanical strength; the prepared BOPP film is large in elastic modulus and low in heat shrinkage rate; the performance indexes such as haze and glossiness of the outer surface layer are excellent.

Description

technical field [0001] The invention relates to a matte leather transfer BOPP film and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] The transfer film is usually made of gravure coating, vacuum aluminum plating and back-coating hot-sol on the PET film. The aluminum layer and color can be transferred to paper, leather, textiles and other substrates by heating and pressure. Changing the appearance and quality of the base material plays a role in improving the product grade. Leather companies usually use BOPET film as a transfer film, mainly because of its high rigidity and low thermal shrinkage. In recent years, due to the impact of the international environment, the price of BOPET has risen to about 30,000 yuan / ton, and the delivery time is long, which greatly increases the cost of manufacturers. Therefore, it is urgent to develop a new type of transfer film to replace BOPET film. [0003] In recent years, mat...
