This equipment primarily serves applications requiring precise sealing, such as commemorative coin sleeves, collectible folders, and card packaging.
Suitable raw materials include PET (polyethylene terephthalate), PETG (amorphous copolyester), GAG (three-layer co-extruded sheet), and PVC (polyvinyl chloride). These materials, due to their high transparency and toughness, are commonly used in high-end packaging.
For example, commemorative coin sleeves require a seamless seal achieved through a high-frequency welding machine, protecting the coin surface from scratches and enhancing the overall aesthetics.
Furthermore, the equipment supports customized molds, adaptable to sleeves or collectible folders of different sizes, meeting diverse production needs.
