Abstract
A safety adhesive tape having a base layer, a hard resin layer, an adhesive layer, and an anti-sticking layer, the base layer being a plastic film, the hard resin layer being coated on the top side of the base layer, the adhesive layer being coated on the bottom side of the base layer for sticking, the anti-sticking layer being a stripping film covered on one side of the hard resin layer opposite to the base layer. The hard resin layer changes the structural property of the adhesive tape, enabling the adhesive tape to be easily pulled apart with the hands, or cut with a cutter.
