SOS (Square Bottom Square) refers to the "square bottom straight cylinder" structure, which is different from ordinary handbags. Its bottom is flat, stable when standing, and has a high volume ratio. It is particularly suitable for holding items such as gift boxes, baked goods, clothing or electronic products that need to be protected from tipping over and easily stackable. White kraft paper also combines high white paper printing performance with the environmental attributes of natural fibers. White kraft paper has become the first choice for high-end customization due to its high whiteness, strong stiffness and food-grade safety.
The core competitiveness of the large SOS white kraft paper tote bag lies in the "large capacity × high appearance level × strong environmental protection" combination - it is not an ordinary shopping bag, but a brand premium tool: it wins consumer trust by having verifiable environmental protection attributes, reduces transportation waste by having precise dimensions, and enhances visual memory through high-quality printing.
