Self Seal Polypropylene Bags

Self-sealing PP bags feature a convenient closure system that allows the bag to be securely sealed without the need for additional equipment such as tape or heat sealers. The closure system typically consists of a strip of adhesive located along the top of the bag. Once the bag is filled with the product, the adhesive strip is pressed firmly against the bag to create a tight seal.
