Title:
ADHESIVE TAPE DEVICE EASY TO PEEL OFF AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/155800
Kind Code:
A1
Abstract:
An adhesive tape device easy to peel off and a manufacturing method therefor. The adhesive tape device comprises an adhesive tape substrate having a substrate length and a substrate width. One side of the tape substrate is coated with an adhesive layer. One side and/or both sides and/or middle region of the adhesive layer along the substrate length is coated with a liquid material that can form a film after drying to form one or more non-adhesive regions. The region of the adhesive layer that is not coated with the liquid material that can form a film after drying forms an adhesive region. After the adhesive tape device is stuck to a packaging box/bag, because one or both sides of the adhesive tape are non-adhesive, the adhesive tape can be easily peeled off from the packaging box/bag, the packaging paper box/bag can be opened without using a tool, and the adhesive tape does not have any residue on the packaging box, thus facilitating paper box recycling. When the paper box is discarded, the classification of the paper box and plastic adhesive tape is also facilitated, thus reducing environmental pollution. Moreover, the manufacturing costs of the adhesive tape device are low, no additional equipment is required, the efficiency is high, and industrial mass production can be achieved.
