Core Product Positioning: Your exclusive starting point for packaging
We offer PET preforms specially designed for edible oil, alcoholic beverages and high-end liquid foods. Taking the standard diameter of 27mm (outer diameter 27mm/ inner diameter 22mm) as the core starting point, it is made of food-grade PET material and formed in one piece through precision injection molding process. We are not only a preform supplier, but also your partner in packaging solutions. Through in-depth customization of specifications and colors, we help you shape a unique brand image and ensure that your products are perfect from the production line to the shelves.
Why Choose Our PET preforms? Interpretation of the Four Core Values
Precise and rigorous bottle mouth design
Precise dimensions: The core diameter is 27mm, with strict tolerance control to ensure perfect compatibility with mainstream filling equipment, capping machines, and anti-theft caps.
Sealing guarantee: The optimized inner diameter design of 22mm provides a solid foundation for the inner plug or sealing valve, which is the first key to achieving long-term preservation of the product and preventing leakage and seepage.
Strong versatility: This specification is one of the widely accepted standards in the industry, facilitating your purchase of matching cover types and making supply chain management more efficient.
Safe and outstanding PET material
Food-grade safety: Made from 100% food-contact grade PET raw materials, it complies with relevant national standards, is odorless and non-toxic, and ensures the purity and original aroma of the contents.
Outstanding performance: It features excellent transparency, impact resistance and chemical stability. Lightweight bottles can reduce logistics costs, while high barrier properties can effectively protect the flavor of oil and wine and extend their shelf life.
