PET in its most stable state is a colorless, semi-crystalline resin. However it is intrinsically slow to crystallize compared to other semicrystalline polymers. Depending on processing conditions it can be formed into either amorphous or crystalline articles. Its amenability to drawing makes PET useful in fibre and film applications. Like most aromatic polymers, it has better barrier properties tha… WebWe know that thermoforming is about quality and speed. Whether through deep-drawing, sealing, or heat sealing – our PET films add value. We have the packaging film that fits …
