Abstract

The invention discloses a colored protective film which comprises an anti-scrape protecting layer, a tensile buffer layer, a colored transmitting layer and a matrix film. The colored transmitting layer covers one face of the matrix film, the tensile buffer layer covers one face of the colored transmitting layer, and the anti-scrape protecting layer covers the surface of the tensile buffer layer. The colored protective film has a certain shading property, and can protect some photosensitive objects. Compared with a common white protective film, the colored protective film is brighter in color,and is more attractive, and packaging and propagandizing of a product are facilitated.

Description

technical field [0001] The invention relates to a protective film, in particular to a colored protective film. Background technique [0002] At present, the appearance of many commodities will be covered with a protective film. By sticking the protective film on the surface of the article, the article will not be stained with dirt, and will not be easily scratched. [0003] Most of the existing protective films are made of plastic film, which is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging, and used as a coating layer. 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., the...
