The difference between special-shaped bag packaging machines - full punch special-shaped bag packaging machines and clamp and pull special-shaped bag packaging machines
Full punch special-shaped bag packaging machines and clamp and pull special-shaped bag packaging machines mainly differ in working principle, scope of application, and packaging effect:
1.Difference in working principle
•Full punch special-shaped bag packaging machine: It forms special-shaped bags by one-time injection molding, which is usually suitable for soft materials such as plastics. This machine injects molten plastic material into the molding mold, forms a bag of a predetermined shape after cooling, and then performs filling, sealing and other steps.
•Clamp and pull special-shaped bag packaging machine: It is more used for prefabricated film materials, clamps and stretches the film through mechanical action to form a special-shaped bag shape, and then fills and seals the material. It is suitable for a variety of film materials, including but not limited to PE, PET, composite film, etc.
2.Difference in scope of application:
•Full punch special-shaped bag packaging machine is more suitable for producing special-shaped packaging bags with a single material and fixed shape, and is suitable for mass production of the same type of products, such as some special-shaped snack packaging.
•The clamp-pull special-shaped bag packaging machine is more flexible and can adapt to the needs of different materials and size changes. It is easy to quickly change molds or adjust, and is suitable for small-batch production scenarios with diversified products.
3.Packaging effect and cost:
•The edges of the packaging bags produced by the full-punch special-shaped bag packaging machine are usually smoother and the overall appearance texture is better, but the initial equipment investment and production cost are relatively high.
•Although the clamp-pull special-shaped bag packaging machine may not be as precise as the full-punch in processing complex shapes, it is more economical and efficient in adapting to variable designs and rapid shape change, especially suitable for situations where product forms need to be adjusted frequently.
In summary, the type of special-shaped bag packaging machine to choose depends on the specific product needs, production scale and cost considerations. I hope this information can help you better understand the difference between the two machines and make a suitable choice.
