Description

Anti-deformation foam adhesive tape structure

Technical Field

The application relates to the technical field of gum, especially, relate to a shape bubble cotton tape structure of preapring for an unfavorable turn of events.

Background

The foam adhesive tape is manufactured by coating a solvent type (or hot melt type) pressure-sensitive adhesive on one surface or two surfaces of EVA (ethylene vinyl acetate) or PE (polyethylene) foam which is taken as a base material and then compounding a release film, and has the functions of sealing and shock absorption.

At present, the foam adhesive tape is widely applied to the fields of electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories and the like, and when the foam adhesive tape is used, the release film is torn off, and the foam adhesive tape is attached to the surface of the product.

But because the cotton material of bubble itself is softer, easy the deformation, so bubble cotton sticky tape keeps ride comfort and certain hardness very necessary when attached, especially to the bubble cotton sticky tape that attached size is great, the frame size is narrower, the individual layer can not support the hardness of whole bubble cotton sticky tape from the type membrane to bubble cotton sticky tape warp very easily when attached, leads to bad conditions such as crooked fold, has reduced laminating quality.

SUMMERY OF THE UTILITY MODEL
