The thermoforming packaging machines can soften the thermoplastic rigid plastic sheet of polyvinyl chloride or polydichloroethylene or the like, and can form the plastic sheet into a container for accommodating the material by vacuum blistering or punch punching, and then Cool the setting and load the material.
After heat sealing with a layer of aluminum foil or cellophane coated with adhesive and composite materials, the package can be finished by cutting. Packaging machines that can perform this series of work (some without cutting) are generally referred to as thermoformed packaging machines.
Such packaging machines are generally designed to package tablets, capsules, and injections. The packaged product is in the form of a blister, so there is also a name for the blister pack, which is transparent and visible, and is very convenient for storing, carrying and taking medicines.
The packaging method has now been developed to be able to package any material in any form, and the thermoformed containers are not in the form of small blister, but can also be used in packaging foods, daily necessities and electrical components. The package has the advantages of light weight, good sealing, ‘adaptive, transparent, easy to sell and consume, so the thermoforming packaging machines have developed rapidly in recent years.
