Title:
ANTIMICROBIAL HEAT-SHRINKABLE PLASTIC FILM AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH03126741
Kind Code:
A
Abstract:
PURPOSE:To obtain an antimicrobial heat-shrinkable film obtained by melting and kneading an ionomer, amide-based lubricant, silica-based blocking preventing agent and inorganic antimicrobial agent at the formation of film by means of blown-film extrusion followed by forming into tube-like film and biaxially orientating the film. CONSTITUTION:The objective heat-shrinkable plastic film obtained by uniformly blending (A) 100 pts.wt. ionomer, especially zinc ion type ionomer with (B) <=8 pts.wt. amide-based lubricant, (C) <=4 pts.wt. silica-based blocking preventing agent and (D) <=1 pts.wt. inorganic antimicrobial agent having a structure in which an antimicrobial metal ion is added to zeolite, and melting and kneading the blend for film formation by inflation method to form the blend into a tube- like film and biaxially orientating the film, capable of preserving freshness and close-packaging without drip occurrence of meat and having extremely high antimicrobial properties.
