What Are Co-Extruded Polypropylene Bags?
Co-extruded polypropylene bags are made using a multi-layer extrusion process that fuses multiple layers of polypropylene film together. This creates a bag that's thinner, clearer, and stronger than single-layer polypropylene—while maintaining FDA compliance for food safety.
Why Choose Co-Extruded Bags Over Standard Polypropylene?
- Thinner gauge, same strength: Reduces material costs without sacrificing durability
- Superior optical clarity: Displays product attractively for retail applications
- Better seal integrity: Multi-layer construction improves heat sealing performance
- Moisture and grease resistance: Ideal for baked goods, frozen foods, and oily products
Common Applications for Co-Extruded Polypropylene Bags
- Bakery packaging: Cookies, brownies, muffins, bread loaves
- Frozen food storage: Maintains product integrity at sub-zero temperatures
- Microwave-safe reheating: Safe for consumer use in microwave ovens
- Retail food displays: Clear bags showcase products on store shelves
- Produce packaging: Vegetables, fruits, and other fresh foods
Available Formats
Side Gusset Co-Extruded Bags
Side gusseted bags expand to accommodate bulkier products while standing upright for display. Perfect for coffee, nuts, granola, and other dry goods.
Bottom Gusset Co-Extruded Bags
Bottom gusseted bags provide a flat base that allows the bag to stand independently—ideal for retail merchandising and point-of-sale displays.

Co-Extruded Polypropylene Bags: Frequently Asked Questions
What are co-extruded polypropylene bags?Co-extruded polypropylene bags are bags made by fusing several layers of polypropylene film together in a single extrusion process, which produces a bag that is thinner, clearer, and stronger than single-layer polypropylene. Prism Pak stocks them in side gusset, bottom gusset, and wicketed formats for food packaging. Are co-extruded polypropylene bags food safe?Yes. Prism Pak co-extruded polypropylene bags meet FDA requirements for direct food contact under 21 CFR 177.1520 and contain no harmful plasticizers. They are approved for dry foods such as bakery and snacks, fatty and oily foods such as pastries and fried items, frozen foods, and microwave reheating. Can co-extruded polypropylene bags go in the freezer and the microwave?Yes, both. The co-extruded film is freezer-safe at sub-zero temperatures and microwave-safe for consumer reheating, so one bag covers frozen storage and reheat. That is why food processors and frozen-food packers use it in place of separate freezer and reheat packaging. What is the difference between co-extruded and standard polypropylene bags?Co-extruded bags use multiple bonded film layers instead of one, so they deliver comparable strength at a thinner gauge. Compared with standard polypropylene, that means lower material cost per bag plus better optical clarity, stronger heat seals, and improved resistance to moisture and grease. What are wicketed co-extruded polypropylene bags used for?Wicketed co-extruded bags come pre-loaded on a metal wicket so an operator or machine can fill and tear off one bag at a time. They are used in high-volume bagging operations — bakeries, produce packers, and food processors — and work with both automated packaging equipment and manual dispensers. Who uses co-extruded polypropylene bags?Wholesale bakeries, food processors, produce packers, and retail food operations are the primary users. Typical contents include cookies, brownies, muffins, and bread loaves; coffee, nuts, and granola in side gusset styles; frozen meat, seafood, and vegetables; and fresh produce for retail display.
