The preform is an intermediate product, which is then blown into a bottle. The neck finish, weight, color and shape of the preforms are different, and they are specially designed to meet the needs of customers in different markets.
Preforms can be made of PET, and PP materials, so they are called PET preforms and PP preforms. They are produced by Kerui using high-precision injection molding technology.

The weight of the preform depends on the required volume of the final container. The preform can be single-layer or multi-layer. Because a special coating is embedded in multiple layers, the preform can extend the shelf life of the beverage.
