Glass for packaging

Amorphous PET is transparent with light transmittance ranging from 80% up to 92%, haze of roughly 0.3-1.3% and a refractive index of about 1.575. Glass Polymers are specially designed to mimic thick glass for packaging cosmetics and healthcare products. 

Household and industrial chemical containers are increasingly being made of plastics. HDPE has almost completely replaced glass for packaging household liquids. However, for solvents and flammable liquids, a plastic is required with higher barrier properties than conventional HDPE.
