Abstract

The invention discloses a matte forming film, a preparation method thereof and a matte packaging material. The matte forming film comprises a matte layer, a core layer and a corona layer which are sequentially arranged, the weight ratio of the matte layer to the core layer to the corona layer is (0.8-1.2): (6-8): (1.5-2.2), and the matte layer, the core layer and the corona layer are prepared through a co-extrusion process. The matte packaging material comprises a plastic base material layer, a gloss oil layer and a matte forming film. According to the matte forming film, the preparation method of the matte forming film and the matte packaging material, the matte forming film can enable the packaging material to present a high-grade matte effect, cracking or appearance change does not occur during secondary forming, and the matte forming film is good in tensile strength, good in light transmission, long in corona retention time and capable of being well adhered to printing ink and glue. The matte forming film can replace matte ink to cover the surface of a pattern, can be used as a wear-resistant protective layer while providing a three-dimensional and matte high-grade effect, andprovides protection for a gloss oil pattern and a plastic base material layer.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a matte forming film, a preparation method thereof and a matte packaging material. Background technique [0002] With the improvement of people's material living standards, the requirements for the hygiene and convenience of various food and daily necessities are getting higher and higher. Plastic packaging has been favored because of its light weight, low cost, various packaging forms, convenient use, and high safety factor. More and more brands and consumers favor. However, the competition in the plastic packaging market is becoming increasingly fierce, and product changes are changing with each passing day. In order to seize the market or stand out from the competition of products of the same category, various brands have adopted more novel packaging forms or appearance designs to gain higher attention and loyalty. [0003] Rather than attracting attention through b...
