Eight-side seal bags

Flat-bottom bags for strong shelf presentation

Flat-bottom bags give a box-like shape, wide front panel and stable base for premium coffee, snacks, pet food and dry goods.

01Flat-bottom display applications

Coffee and tea

Premium shelf packs with valve, zipper or aroma barrier depending on product needs.

Snacks and dry goods

Stable retail packs for nuts, granola, cereals and pantry products.

Pet food and treats

Stronger shelf presence for pet treats and heavier dry products.

02Material, structure and finish options to confirm

Panels, gussets and zipper

Plan front, back, side and bottom panels together. Zipper, valve, window and matte finish all need to respect folded areas.

Artwork across five panels

Flat-bottom bags need careful dieline control because artwork crosses front, back, side gussets and bottom areas.
