One of the most common applications of PET preform mould is in the beverage industry. Preforms are used to create bottles for a wide range of beverages, including water, soft drinks, and alcoholic drinks. The lightweight and shatterproof nature of PET makes it an ideal material for these applications.

PET preforms are also widely used in food packaging. They are used to create containers for products such as salad dressings, condiments, and edible oils. The material's barrier properties help to preserve the freshness and flavor of the contents.

In the cosmetics and personal care industry, PET preforms are used to create bottles for products like shampoos, lotions, and perfumes. The material's clarity allows for the product to be visible, which is often a desirable feature in these markets.

PET preforms are also finding applications in pharmaceutical packaging. They are used to create bottles for medications and supplements, taking advantage of PET's resistance to chemicals and its ability to maintain a tamper-evident seal.

For industrial and household chemicals, PET preforms are used to create sturdy and durable containers. The material's resistance to chemicals makes it suitable for products like cleaning solutions and automotive fluids.
