A Clean Canvas for Your Branding
Because the seal runs down the back rather than the sides, the front and back panels stay fully open for artwork with no visible seam interrupting your design. This makes the back seal bag a favorite for brands that want maximum shelf-facing graphics on a budget-friendly flexible format.
Who Uses This Format
- Snack food brands running high-speed form-fill-seal packaging lines.
- Coffee and tea roasters needing a barrier film with a clean face.
- Candy and confection makers printing bold full-panel graphics.
- Bulk goods sellers packaging grains, pet treats, or dried foods.
Material and Format Options
Choose BOPP film for a glossy retail look, PET/PE laminate for stronger barrier protection, or kraft paper film for a natural, eco-forward appearance. Matte, gloss, and metallic finishes are all available, with optional zippers or tear notches for consumer convenience.
