is to heat and soften thermoplastic rigid plastic sheets such as polyvinyl chloride and polyvinyl chloride, and then use vacuum suction and punching to form the plastic sheet into a container for the material, and then cool and shape it, then load it. materials. A layer of aluminum foil coated with an adhesive and cellophane, composite materials, etc. are then heat sealed together, and then cut to complete the packaging. This series of working packaging machines is called thermoforming packaging machines.
Thermoformed Packaging's packaging method has now been developed to package any material in any form. Thermoformed containers are not just small blister-shaped, but larger trays, cups, bowls, and used to package food, daily necessities, and electrical components. Wait. This kind of packaging has the advantages of light weight, good sealability, strong adaptability, transparency and visibility, and no additional buffer material for packing, which is convenient for sales and consumption, so it has developed rapidly in recent years. In line with this, thermoforming packaging machines have also developed rapidly in recent years.
