What Are Co-Extruded Polypropylene Bags?

Co-extruded (co-ex) polypropylene bags are manufactured using a specialized process that bonds multiple layers of polypropylene film together. This creates a bag that's significantly stronger and more durable than single-layer poly bags, while using less material overall.

The result? A thinner, clearer bag with superior puncture resistance, better seal strength, and excellent moisture and grease barriers—ideal for demanding food packaging applications.

Frequently Asked Questions

Are co-extruded bags better than regular poly bags?

Yes, for most applications. Co-ex bags are stronger, clearer, and more puncture-resistant than standard single-layer polypropylene bags, while using less material. They're especially superior for food applications requiring freezer or microwave safety.

Can I heat-seal these bags?

Absolutely. Co-extruded polypropylene bags seal extremely well with standard impulse sealers or continuous heat sealers, creating strong, reliable closures.

What's the difference between side gusset and bottom gusset?

Side gusset bags expand on the sides and lay flat when empty, ideal for stackable items. Bottom gusset bags expand at the bottom for a stable base, better for heavier or bulkier products.

Are these bags recyclable?

Polypropylene (#5 plastic) is recyclable where facilities accept it. Check with your local recycling program for specifics.
