Antibacterial and anti-sticking master batch for BOPP film and preparation method of antibacterial and anti-sticking master batch

The invention discloses an antibacterial anti-sticking master batch for a BOPP (biaxially-oriented polypropylene) film and a preparation method of the antibacterial anti-sticking master batch, and the preparation method comprises the following steps: uniformly mixing a dispersing agent and a compound anti-sticking agent to obtain a mixture A; uniformly mixing the dispersing agent and the compound antibacterial agent to obtain a mixture B; putting the mixture A and the mixture B into a high-speed stirrer, stirring for 10-15 minutes under the conditions that the temperature is controlled to be 98-105 DEG C and the stirring speed is controlled to be 240-280 r/min, then adding homo-polypropylene, a compatilizer, an antioxidant and a nucleating agent, continuously stirring for 12-16 minutes, then putting into a double-screw extruder, heating to 160-190 DEG C, extruding, granulating and drying by the double-screw extruder to obtain the antibacterial and anti-sticking master batch for the BOPP film.
