Other Characteristics of PETG:
Durable material with excellent gloss and clarity, making for very clear bottles. PETG is popularly used to house shampoos, soaps, pharmaceutical products and detergents and has good impact strength and gas barrier qualities. PETG has good chemical reistance to acids, alkalis and solvents. The chemical resistance is fair, and as always, be sure to test your product for compatibility with PETG.

PETG for Laboratories:
PETG is a good material for laboratory use because of its clarity and gas and moisture barrier. Clarity ensures that your products will be visible to the naked eye, and many PETG containers could be labeled for a wide range of laboratory products. PETG could be used for many applications, such as water testing because of the good moisture barrier this plastic can provide. PETG can be sterilized by gamma irradiation.
Recycling:
PETG can be identified easily by locating its recycling code symbol. PETG is denoted by the familiar triangular shaped arrows with the number 1 in the center. For more information regarding PETG recycling see the Plastic Container Recycling Page
