Cold seal technology
Cold sealing technology does not rely on heat but instead uses special adhesives or interlayer materials to achieve a seal. This method is suitable for heat-sensitive products.
Ultrasonic sealing
Ultrasonic sealing uses the heat generated by high-frequency vibrations to melt plastic film and achieve a seal. This method does not require an external heating source and has a fast sealing speed.
Heat sealing technology
Heat sealing is a method of melting the contact surface of plastic film or laminated material by heating, and then rapidly cooling to form a seal. This technology applies to a variety of plastic materials, such as PE, PP, PET, etc.
