One kind of tissue Gusseted Gusseted method and apparatus for sealing bags

Gusseted Gusseted method and apparatus of the present invention discloses a tissue sealed bags, which method is based on airflow Gusseted promote ways to promote the film bag folded inward bags. The apparatus includes Gusseted Gusseted block; provided may be formed blown film bags and bags it bent inward toward the air flow duct and the blow hole and blow hole communicating on the Chajiao block the airflow and a source connected to a gas pipeline. The present invention utilizes the airflow-driven approach to replace the traditional triangle Chajiao plate, when required Chajiao, use of air which can form an invisible gas Chajiao, and eventually formed a smooth film without the knuckle and no dead marks folding curve. Compared with the prior art, the present invention can greatly improve the stability of the bag during sealing, thus reducing the reject rate seal.
