  • Detail

The air check valve of inflatable packaging bag is composed of upper and lower air valve films and a number of heat-resistant printing sandwiched in the middle. It is characterized in that the air valve composed of upper air valve film and lower air valve film is clamped between the upper and lower films with appropriate length and arranged in a way that spans the entire inflatable packaging bag. On the, this machine is the best choice! Safety measures shall be taken at the pressurizing end of the lower air valve membrane, and the shape heat seal shall be set at the air valve, which greatly improves the working efficiency and serves as the air inlet and air stop mechanism of each air chamber. The shape of the shaped thermal printing point is a circle or other shape. A heat-resistant printing is arranged between the upper and lower air valve membranes, which is just located at the air inlet and is also arranged in a way that spans the entire inflatable packaging bag 1. The upper air valve film and the lower air valve film are films made of plastics or plastics. The designed air check valve of the inflatable packaging bag will not have any problems such as being unable to align when stamping the heat sealing line of the air chamber, which can improve the manufacturing speed, improve the product qualification rate, and greatly reduce the manufacturing cost
