The SOS handbag (Self-Opening-Self-Locking) is an eco-friendly bag type that does not require glue and is self-locking through its paper structure. It is widely used in high-end gifts, baking, seafood gift boxes, etc., where quick opening and prevention of spillage are required. White kraft paper, due to its double-sided whiteness, high tensile strength, and excellent printing properties, has become the mainstream material for SOS bags.
The extra-large white kraft paper SOS handbag is made from 150-250g high-gloss white kraft paper as the base material. It features the SOS (Self-Opening-Sack) self-opening structure design, which combines strong load-bearing capacity (≥5kg), high stiffness, food-grade safety and environmental-friendly degradability. It is widely used for high-end gifts, seafood gift boxes, large baking items and cross-border independent website packaging. "White kraft paper" emphasizes the material - different from traditional yellow kraft paper, white kraft paper is bleached or pulped to whiten, and it has high tensile strength, food-grade safety and good printing adaptability.
