Can Plastic Water Cups Be Produced in Double Layers?

There are many kinds of water cups on the market, stainless steel water cup, glass water cup, plastic water cup, etc.? Both the stainless steel water cup and the glass water cup can be made into a double-layer structure, which can provide a temperature insulation effect. The hot water is installed inside, and the hands are not particularly hot, so it is convenient to carry.

Why do the plastic cups on the market basically have a single layer, can they be double-layered? Can it also function as heat insulation?

The plastic cup can be double-layered and can also play a role in heat insulation. The reason why plastic cups on the market are basically single-layer is because many raw materials for processing plastic cups cannot withstand high temperatures above 60°C. The plastic water cups made of these materials are filled with cold water or cold drinks daily, and do not need to function as heat insulation. Once filled with boiled water, the water cup is easily deformed and releases the harmful substance BPA. If the plastic cup can be directly filled with boiling water, only Tritan material can be used to achieve no deformation and no release of harmful substances BPA.

The double-layer plastic water cup is made of Tritan raw materials and adopts advanced ultrasonic technology. The double-layer structure is firm and the temperature insulation effect is very obvious.
