Breakable adhesive tape and production method thereof

Номер: CN0101275058B
Автор: YANG YIYANG, YIYANG YANG
Принадлежит:

The present invention provides a breakable adhesive tape, characterized in that the adhesive tape breaks in the length direction for each customization distance along its width direction. The adhesive tape has advantages that the adhesive tape automatically breaks without using cutter or other cutting tool, when achieving customization length, the usage is very simple, and the fracture of the adhesive tape after broken is leveling, and the size is very accurate. In addition, the distance between automatic fractures is set according to customer requirement, that is the customization distance. Preferably, the adhesive tape has a easier tearing mean, partial and completely having no adhesive near the fracture part broken along the width direction. Thus, the usage of the adhesive tape is convenient and saving on one hand, the further peeling of the release paper and the plastic layer is more convenient and saving labour in the application of the two sides tape, and having no phenomenon ofcolloid ...
