30mm（short neck） PET Preform

          The 30mm Short Neck PET Preform is a lightweight packaging solution developed from the traditional standard neck design. By reducing the neck height, it significantly decreases PET material consumption while maintaining excellent sealing performance and functionality. It is widely used for mineral water, purified water, drinking water and other packaging applications.

                       Key Advantages of Short Neck PET Preforms

1.Lightweight Design & Reduced Production Costs
By reducing the neck height and optimizing the structure, the preform uses less PET material while maintaining strength and sealing performance, resulting in lower weight and improved material efficiency. Less PET resin is required for each preform, helping reduce material costs.

2.Environmentally Friendly
The Short Neck PET Preform follows a lightweight packaging philosophy by reducing plastic consumption without compromising performance. Lower material usage helps conserve resources and reduce carbon emissions throughout the production and logistics process. This sustainable approach supports environmental protection goals and aligns with the growing global demand for eco-friendly packaging solutions.

3.Filling Line Compatibility
By adopting the same outer and inner diameters as the 30mm standard  neck finish, it ensures stable compatibility with existing blow-molding equipment and filling lines with minimal impact, thereby eliminating the need for extensive adjustments to production machinery.
