Abstract

The invention relates to a non-sticking yogurt cover film. The non-sticking yogurt cover film comprises five layers of structures which are the ink layer, the polyester layer, a sticking later, a polyethylene layer and a coating in sequence from top to bottom. The thickness of the coating is 3-5 [mu]m, a plurality of concave particles and convex particles are arranged on the surface of the inner side of the coating, and the concave particles and the convex particles are arranged at intervals. According to the non-sticking yogurt cover film, the structure is simple, the design is compact, the polyester layer and the polyethylene layer are composited into a main body, and using of a copper foil layer is reduced, sanitary and convenient effects are achieved, the piercing effect is good, the concave-convex sense of the inner layer is improved through arrangement of the concave particles and the convex particles on the surface of the inner side of the coating, surface tensile force is removed, and yogurt is prevented from being accumulated on the surface.

Description

technical field [0001] The invention relates to a non-stick yoghurt cover film, which belongs to the technical field of packaging bags. Background technique [0002] Yogurt is the most common healthy food in our life, and its sweet and sour taste is also loved by many people. However, every time the yogurt with a cup lid on the market is torn off, a layer of yogurt will stick to it. In order to avoid waste, licking after uncovering has also become a term of ridicule. Contents of the invention [0003] The purpose of the present invention is to solve the problem that a layer of yogurt is easy to stick to the yogurt cover film after it is uncovered, and provides a non-stick yogurt cover film with a simple structure. The design of the inner coating surface removes the surface tension, making the yogurt It is not easy to stick to the cup lid. [0004] The present invention adopts the following technical scheme: a non-stick yogurt cover film, comprising five layers from top t...
