Flat bottom bags are the professional choice for heavy pet products. Whether you are packing dog food or cat litter, the flat base distributes weight evenly and keeps the bag standing upright. No tipping, no sagging, no mess.

OEM printing means we produce bags to your exact specifications. Send us your brand design and we handle the rest – color matching, layout, print positioning. The result is packaging that looks like it came from a major brand, even if you are just starting out.

The zipper ziplock closure is reinforced for heavy products. Dog food and cat litter are dense and abrasive, so the zipper needs to hold up under real-world conditions. We test every zipper batch for seal strength and durability.

For brands that need a different format, we also have flat bottom cat litter bags with aluminum-foil laminate and standard plastic cat food bags in smaller sizes.

Customization:

• Flat bottom design – stable base for heavy products
• OEM printing – your brand design, exact colors
• Zipper ziplock – reinforced for pet food and litter weight
• Sizes from 1kg to 20kg
• Matte or gloss finish
• Tear notch and hang hole options
