Food-Grade Plastic Bag Standards: Safety, Regulations & Buying Guide
"Can this bag be used for food?" is one of the most frequently asked questions in plastic bag procurement. For food service operators, food processors, supermarkets, and market vendors, using bags that don't meet food safety standards can endanger consumer health and expose your business to legal liability.
What Makes a Plastic Bag "Food-Grade"?
Food-grade means the plastic product's raw materials, additives, and manufacturing environment comply with food contact safety standards. Requirements include food-grade resin, approved additives, hygienic manufacturing, and no harmful substance migration under normal use.
