At present, disposable snack boxes on the market are mostly made of polystyrene raw materials extracted from petroleum and foaming agents, which are heated and foamed.
Polystyrene is an extremely widely used polymer material, with low toxicity, high melting point, strong plasticity, and easy production. It has become the material of choice for disposable snack boxes.
Plastic tumblers are made of food grade PP or TRITAN plastics. They are FDA certified and BPA free. Plastic tumblers are much lighter, and much cheaper, but they do not have a good temperature retention performance. We have single wall plastic tumblers and double wall plastic tumblers from 10oz to 30oz.
