Three-Side Seal Paper Bags

Three-Side Seal Paper Bags

Three-side seal paper bags are pouch-style packages sealed on the sides and bottom with an opening at the top. 

Their core advantages are strong sealing performance and stable structure, making them suitable for the sealed storage and transportation of various products such as food and daily necessities. 

Made from pure wood pulp or bamboo pulp base paper, they are produced through printing, cutting, and heat-sealing (or cold-sealing) processes, with the sealed edges typically reinforced by heat-sealing for enhanced durability. 

The top features a pre-designed opening, which can be customized with tear notches or easy-tear lines as needed. Some food-grade models meet GB 4806 food contact safety standards, making them a widely used sealed paper bag in the packaging industry that offers both protection and practicality.
