Adhesive label for flexible objects e.g. plastics tube - is combination of flexible film, pref. such as polyethylene and elastomer type of adhesive

摘要

An adhesive label for sticking on flexible things such as plastic tubes. It is a combination of a flexible film with a stretch factor of 150% and an elasticity module of 140, with an adhesive with viscosity 500/1800 centipoises at 170-180 deg.C and softening at about 100 deg.C. The adhesive is a fusible type of elastomer. It can adhere sufficiently to hold the label perfectly at the base of a deformation of the object. The adhesive flows very slightly and is spread at 27/30 g approximately per square meter. The film is pref. plasticised polyvinyl chloride, elastic polyethelene, or amorphous polypropylene.
