Fit type breathable elastic adhesive film

Abstract

The invention discloses a bonding type breathable elastic adhesive film, which comprises an adhesive film main body, the adhesive film main body includes a base film and a surface film attached to the base film, the surface film is an elastic film and the surface film The elasticity is greater than that of the base film, and the base film can be broken after being stretched to a certain extent to cause cracks in the main body of the adhesive film, and the main body of the adhesive film has a gas-permeable state where the cracks exist. After the present invention is stretched to a certain extent, the base film can be broken and the surface film attached to the base film can be broken accordingly, so that the main body of the adhesive film can produce cracks and have a breathable function, and the surface film can be maintained without breaking. Elasticity, and then it can retain the elasticity of the main body of the film. After the main body of the film is pasted on the elastic fabric, it will have breathable performance after being stretched after the first wearing, etc., and it will not disappear in subsequent use, which can effectively guarantee clothing, bags Excellent air permeability, improved wearing comfort, and more convenient processing and use.

Description

technical field [0001] The invention relates to an elastic adhesive film. Background technique [0002] Elastic adhesive films are often used in clothing, luggage, etc. These elastic adhesive films can enhance the elasticity of fabrics, etc., and some elastic adhesive films have hot-melt adhesive properties, which can be used to paste fabrics such as fabrics, thereby reducing the amount of stitching. processing. Existing elastic adhesive films are usually TPU hot-melt adhesive films. These elastic adhesive films are usually airtight. If it is blocked and loses air permeability, it will affect the air permeability of corresponding clothing, bags, etc., especially for elastic underwear, which is widely used in elastic film, which will seriously affect the comfort of wearing. If the melting temperature is too low, it will affect the adhesion between the elastic film and the fabric. Contents of the invention [0003] In order to solve the above problems, the object of the p...
