What are flat poly bags used for? Flat poly bags are open-top polyethylene bags used for packaging, storing, and protecting products across industries including food service, cosmetics, retail, and manufacturing. They can be sealed using heat sealers, twist ties, staples, or tape. What mil thickness do I need for sample packaging? For cosmetic samples, tea packets, and lightweight items, 2 mil thickness provides adequate protection while keeping costs economical. Heavier items or products with sharp edges may require 3-4 mil bags for added puncture resistance. Are LDPE bags food safe? Yes, when manufactured from virgin LDPE resin that meets FDA/USDA specifications (like these bags), they are compliant for direct food contact. This makes them suitable for tea, spices, baked goods, and other dry or semi-moist food products.
