Abstract

The invention discloses a red plastic film. The red plastic film comprises the following components in percentage by weight: 60 to 70 percent of high density polyethylene, 16 to 25 percent of linear polyethylene, 10 to 12 percent of red master batch and 5 to 7 percent of open agent master batch. The red plastic film obtained by proportioning the raw materials has high surface tension, and the surface tension of the film reaches 36 to 43 dynes per centimeters.

Description

technical field [0001] The invention relates to a red plastic film, in particular to a red plastic film capable of increasing surface tension. Background technique [0002] Red plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as a lamination layer. [0003] Plastic packaging and plastic packaging products account for an increasing share in the market, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging , quick-frozen food packaging, cooking food packaging, fast food packaging, etc., these products have brought great convenience to people's lives. [0004] An important index to measure the plastic film is the surface tension. The surface tension of the plastic film depends on the surface free energy of the plastic film, and the surf...
