A variety of bags, with a wide range of options can be made on our equipment. Depending on your needs you can select the type that suits your product and customer best.
The typical machine is loaded with a flat roll of plastic film, which has artwork applied to the exterior or interior of the film. The film approaches the back of a long cylindrical tube, which is called the forming tube. When the center of the plastic is near the tube, the outer edges of the film form flaps that wrap around the conical forming tube. The film is pulled downward around the outside of the tube and a vertical heat-sealing bar clamps onto the edges of the film, bonding the film by melting the seam edges together.
The feeding of material and cutting of the bag can be determined either by bag length, or by indexing to an eyespot, which is detected by a visual sensor.
