Abstract

The invention discloses a label film, belonging to the technical field of films. The label film comprises the following raw materials by weight: 35-45 parts of polyethylene, 25-35 parts of polymethacrylate, 10-15 parts of acrylate, 5-15 parts of color master batch, 1-3 parts of an antioxidant, 0.4-1 part of a leveling agent, and 0.6-1.5 parts of a wetting dispersant. Meanwhile, the invention also discloses a method for preparing the label film by using an extrusion casting machine. According to the invention, the prominent defects of a single-component label film are effectively overcome; meanwhile, the label film is prepared by combining an extrusion casting machine, so surface crystal points of a product can be further reduced, and meanwhile, the glossiness of the product is improved; and the preparation method is simple in process, easy to operate and beneficial to industrial popularization.

Description

technical field [0001] The invention relates to the field of film technology, and more specifically relates to a label film and a preparation method thereof. Background technique [0002] With the rapid development of the economy, the label printing industry has made great progress. At present, there are various label films on the market. PE, PP, PVC and other synthetic materials are commonly used. The film materials are mainly white, matte and transparent. Widely used in food, daily chemical, washing products, medicine, cosmetics, home appliances, supermarkets, logistics and other industries. [0003] Labels can be used in a wide variety of labeling applications and end-use areas. For example, in beverage labels, food labels, home and personal care labels and marking industrial products. The surface of the item to be labeled can be plastic, rubber, glass, metal, ceramic, wood, fabric or paper based. Items to be labeled can be plastic items, glass containers or metal con...
