Thermoforming plastic sheet is a widely used packaging material. The plastic sheet is heated to a flexible molding temperature, formed into a specific shape in a mold, and trimmed to produce a usable product. When it comes to thinner gauges and certain material types, the sheet is heated in an oven to a high enough temperature so that it can be stretched onto the mold and cooled to its final shape. Its simplified version is vacuum forming, which is used in mass production.

There are many kinds of plastics available for thermoforming, mainly Acrylic, ABS, Nylon, PLA, Polybenzimidazole, Polyethylene Terephthalate, Polycarbonate, Polyether sulfone, Polyoxymethylene, Polyether ether ketone, Polyetherimide, Polyethylene, Polyphenylene oxide, Polyphenylene sulfide, Polypropylene, Polystyrene, Polyvinyl chloride, Polyvinylidene fluoride, Polytetrafluoroethylene (Teflon).

DESU Technology mainly supplies PET(Polyethylene Terephthalate), PP(Polypropylene), PS(Polystyrene) thermoformed plastic sheets.
