At Andex, we use PETG, RPET, and PVC materials. PETG (or polyethylene terephthalate), features excellent clarity, durability, and resistance to acids. It's fairly easy to thermoform using PETG. RPET (or recycled polyethylene terephthalate), as it's name implies, is a highly efficient, greener option. With RPET, you still get a strong thermoforming material, making it a great alternative to PETG and PVC. Finally, PVC (or polyvinyl chloride), is the third most used thermoplastic, is quite flexible, and has the ability to form tightly.
