Made entirely of paper with no plastic, these bags feature a specialized paper valve and are compatible with fully automated powder filling production lines, ensuring efficient filling and smooth discharge. Crafted from high-tensile kraft paper, they are resistant to creasing and bursting, while allowing air to pass through without letting powder escape, thereby preventing powder expansion issues. Recyclable and pollution-free, these bags meet environmental regulations and are widely used for packaging edible flour, starch, food additives, and fine eco-friendly powders, ensuring the highest level of cleanliness.
