The thermoforming process involves heating materials to a specific temperature, then applying force to the heated sheet. The pressure pushes it into cavities to take particular forms. Plastics are just one material used in these processes. Here are the most common types of thermoforming plastic in California.
PET Plastics
Polyethylene terephthalate, or PET, is one of the most commonly used thermoformed plastics. It’s used to create packaging, bottle production, and synthetic fibers. Once it is molded into the desired shape, it must dry. Once PET products are completed, they offer excellent resistance and exceptional barriers from outside elements.
Polypropylene
Polypropylene, or PP, is a standard resin. It is translucent in its unpigmented state, resulting from crystallites larger than the wavelengths of light that interfere with light transmission. There are four types of PP.
HIPS Plastics
High-impact polystyrene, or HIPS, is used for rigid or foamed plastics. Since it has a brittle, clear composure, it’s ideal for use as protective packaging, such as food and drink packaging. You have probably seen it used in clamshell containers and trays. HIPS is an economical option that’s easy to form.
PETG Plastics
Polyethylene terephthalate-glycol modified provides excellent impact strength, sound clarity, and decent resistance to alkalis and acids. PETG is easily thermoformed and can be sealed using heat or radio frequency without turning cloudy. It’s often desired in the auto industry and healthcare applications because it is tough, clear, and stable.
