Abstract

The invention discloses a high-strength damp-proof plastic film comprising an outer high-strength plastic film layer, a middle damp-proof layer and an inner plastic film layer from outside to inside. Edges of the outer high-strength plastic film layer and the inner plastic film layer are sealed so that the middle damp-proof layer is sandwiched between the two. Multiple pores, with the diameter ranging from 20 micrometers to 30 micrometers, are distributed on the inner plastic film layer. The outer high-strength plastic film layer comprises an outer film, an inner film and a mesh reinforcing layer between the outer film and the inner film, and the inner film is in contact with the middle damp-proof layer. The plastic film is simple and reasonable in structure, has a drying and damp-proofing function and has high strength and good performance.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a high-strength moisture-proof plastic film. Background technique [0002] The market demand for plastic films from all walks of life in China continues to rise. From the perspective of the application fields of plastic films in China, the packaging industry has the largest consumption, the most varieties, and the most widely used, and its consumption accounts for about 2 / 3. The existing plastic film for packaging has the following disadvantages: 1. It has low strength and cannot fully meet the needs of the packaging industry; 2. It has a single function and has no dry and moisture-proof function. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-strength moisture-proof plastic film, which has a simple and reasonable structure, has the function of drying and moisture-proof, and also has high strength and g...
