Material Properties
Low-density polyethylene at 4 mil gauge provides superior strength while maintaining the flexibility required for bakery and food service operations. The material offers excellent chemical resistance to most acids and bases at room temperature, making it suitable for diverse food products. LDPE's inherent moisture barrier properties protect bread and baked goods from humidity while preventing drying. At this thickness, the bags resist puncture from crusty bread surfaces and maintain integrity during high-volume packaging operations.
