Instant Snap-Open Filling. Classic Self-Standing Sacks.
Classic self-opening unhandled paper sacks with a square block bottom for grocery, bakery, and takeaway.
Custom SOS Paper Bags (Self-Opening Sacks) are the quintessential unhandled flat-bottom paper bags used across bakeries, grocery stores, pharmacies, coffee roasters, and food delivery services worldwide. Engineered with an automatic self-opening design, a light flick of the wrist opens the bag completely, allowing high-speed order filling in fast-paced retail and kitchen environments.
Constructed from heavy-duty 60 GSM to 120 GSM unbleached natural kraft paper or white bleached paper, these sacks feature deep side gussets and a rigid square block bottom base. This flat base enables the bag to stand upright independently on packing tables. The unhandled top rim can be folded down or sealed with a custom tamper-evident sticker.
