SOS bags for takeaway food are intended for quick packing and customer handoff where food must move from a service counter to off-site consumption. At Lanfon Hwakon, we develop SOS bags for takeaway food for packaged meals, snacks, bakery products, deli items, café foods, and other suitable takeaway applications. The self-opening structure allows the bag to stand during order assembly, helping staff place several items into the package without continuously holding the bag open. Width, gusset, height, paper appearance, and printing can be customized according to order volume and product dimensions. We consider how SOS bags for takeaway food are stored behind the counter, opened during peak periods, filled with mixed items, handed to customers, and carried during transport. This makes the specification particularly focused on takeaway workflow, packing speed, and convenient order organization.
