Amorphous polyester sheet (PETG)
GPET, also known as PETG, is an amorphous PET resin modified with cyclohexanedimethanol. Its melting point is low, only 180°C to 200°C. When PETG sheet has the characteristics of APET sheet, its biggest feature is outstanding heat sealing performance, easy operation during sealing and reliable heat sealing quality. Compared with APET, PETG does not crystallize at very high molding temperatures. For vacuum molding, it is even possible to obtain clear outlines of complex geometric shapes, but it is more expensive.
PETG has the same chemical stability as APET.
Excellent punching and cutting properties, the punching force required is approximately 10% less than APET. For heat sealing of PETG coated paperboard, the sealing temperature range is 180~250℃ and the sealing time is 1.2~3s; for the heat sealing of coated cover film, it is 170~200℃ and the sealing time is 0.7~2s. PETG or PETG / APET / PETG full plastic covers can be heat sealed. Bonding is the same as APET. Welding is the same as APET, PETG can also be welded by high frequency.
PETG products have high transparency, good gloss, and glass texture. It is a new transparent engineering plastic with excellent impact strength, strong toughness, good heat resistance, good weather resistance, excellent chemical resistance, strong tinting power, and easy molding. It has the advantages of good processing and hygiene (in compliance with FDA), does not contain bisphenol A, and belongs to a new generation of environmentally friendly plastics.
