Square Bottom Kraft Paper Bag – 220‑540mm Wide, 80‑140gsm, Reusable Adhesive Seal

The square bottom kraft paper bag is a premium packaging solution designed for businesses that need large capacity, strong load‑bearing, and a professional retail presence. Unlike flat bags that collapse when filled, the square bottom design allows the bag to stand upright on its own - making it ideal for retail display, grocery packaging, gift presentation, and e‑commerce shipping.

Constructed from high‑quality kraft paper (80‑140gsm), this bag offers exceptional toughness and tear resistance, capable of holding heavy items without breaking or deforming. The generous size range - finished width 220‑540mm, height 400‑770mm, and bottom gusset 70‑200mm - accommodates everything from small gifts to bulky retail items.

The two‑way centrifugal paper adhesive strip is a standout feature: it allows the bag to be sealed and re‑opened multiple times without losing adhesion, making it perfect for products that need occasional access. The built‑in easy‑tear strip enables customers to open the bag effortlessly - no scissors required. The bag is 100% recyclable, biodegradable, and plastic‑free, helping your brand meet sustainability goals.

Ideal for retail shopping, grocery takeout, gift packaging, boutique merchandise, and e‑commerce shipping.
