Abstract

The invention discloses a preparation method of a packaging adhesive tape, wherein the packaging adhesive tape sequentially comprises a release layer, a substrate layer and an adhesive layer from outside to inside, and the preparation method comprises the following steps: 1) carrying out double-sided corona treatment on the surface of the substrate layer; 2) coating the release layer on the surface of one side of the base material layer subjected to corona treatment in the step 1) in a thermal crosslinking or UV crosslinking manner; 3) coating the other side of the base material layer in the step 2) with an adhesive and drying; 4) curing the semi-finished product dried in the step 3); and 5) cutting and coloring the cured semi-finished product in the step 4) to obtain the packaging adhesive tape. When the adhesive tape is used in an automatic laminating device, the adhesive surfaces of two rolls of adhesive tapes are laminated with each other when medical supply wastes pass through an input port of the automatic laminating device, the medical supply wastes are packaged in the adhesive tapes, and the bonding strength, the adhesive force and the soaking impermeability of the adhesive tapes are generated during laminating, and leakage and diffusion of medical supply wastes are avoided.

Description

technical field [0001] The invention relates to a medical packaging tape, in particular to a preparation method of the packaging tape. Background technique [0002] Medical supplies waste is directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in medical treatment, prevention, health care and other related activities. It is highly infectious, biologically toxic and corrosive. Including cotton balls, cotton swabs, drainage tampons, gauze and other various dressings contaminated by the patient's blood, body fluids and excrement. The above-mentioned wastes are usually directly discarded into medical waste packaging bags. During the discarding process, it is usually necessary to keep the packaging bag open all the time. Even if a flip-top trash can is used, the medical waste packaging bag will be kept open when discarding. Increased the risk of leakage and spread of medical waste. Therefore, it is necessary to adopt a ...
