Kraft Paper Air Bubble Envelop Bag Making Machine is the independent innovation product of our company by many years research and development. This machine is specially for making air bubble envelop bag ，suitable for kraft paper , pearlescent film, or aluminized film, co-extrusion film and bubble film and so on. The machine is controller by Delta PLC，Man-machine interface, Servo traction. Unwinding speed is uniform and synchronous，and use photoelectric correction(EPC). It has the function of easy operation, automatic counting and segmenting, automatic stopping when missing printing marks, automatic stopping when lack of raw materials, movable cutting knife and so on. It operates stable, products comes smooth and nice-look, reliable sealing and adhesion. It is the best and reliable equipment for making kinds of compounded air bubble envelop bags.
A Kraft paper air bubble envelop bag making machine is a specialized piece of equipment designed to produce packaging solutions that combine the natural and eco-friendly properties of Kraft paper with the protective cushioning of air bubble film. These bags are used for packaging delicate and fragile items while minimizing the use of traditional plastic materials. The machine is capable of automatically creating Kraft paper air bubble envelop bags, offering a sustainable and effective packaging solution
