As a core prefabricated component in the field of large capacity packaging, 55mm PET preforms dominate in scenarios such as bottled water and large bottled beverages due to their ultra wide diameter structure and performance characteristics suitable for heavy-duty packaging. Their core advantages are concentrated in the following four dimensions:

Accurate adaptation to high-capacity scenarios: covering core requirements of heavy-duty packaging

Core application highly focused

Designed specifically for 3-5 gallon (approximately 11.4-18.9L) bottled water, and can be blown into 5-7L large bottled mineral water and functional beverages, accurately matching the needs of large capacity drinking water scenarios such as home, office, and commercial use.

Flexible matching of weight and capacity

Provides multiple weight options ranging from 180g to 800g, such as 700g, which can accurately adapt to 20L standard bottled water. Differentiated weight design meets the structural strength requirements of different capacity packaging.

Strong adaptability to filling and use

The ultra wide caliber design facilitates rapid filling of large capacity water bodies, and is also compatible with the insertion tube water intake structure of commercial water dispensers, balancing production efficiency and terminal use convenience. It is a standard configuration in the bottled water packaging industry.

Excellent structural and material performance: ensuring the reliability of heavy-duty packaging

High strength impact resistance: Made from 100% new PET raw materials, the material has both high toughness and compressive strength. After blowing, it can withstand the weight and pressure of stacked water in barrels and the impact during transportation, greatly reducing the risk of rupture.

Tighter sealing protection: adopting a standardized threaded neck design, it can adapt to various sealing bottle caps such as press type and spiral type, with tight bite and anti vibration, effectively blocking air and dust intrusion. Combined with the low water absorption characteristics of PET material, it extends the shelf life of water bodies.

Stable molding quality: The eccentricity is strictly controlled during the production process, and the surface of the preform is smooth and scratch free. The success rate of bottle blowing can reach 99.7% -99.8%, and the scrap rate is extremely low, ensuring consistent quality in large-scale production.

Production and Cost Efficiency Optimization: Adapting to Large Scale Manufacturing

Adapting to efficient production lines: Adopting mature hot runner mold production technology, with high weight and dimensional accuracy, it can match the high-speed bottle blowing and filling production lines in the bottled water industry. With a fast delivery cycle of 7-30 days, it meets the needs of large-scale supply.

Controllable full chain cost: Lightweight preform design reduces weight costs during storage and transportation, standardized production processes reduce raw material loss, and a mature supply chain system enables factory direct supply pricing, enhancing cost competitiveness.

Flexible customization response: Supports multi color customization such as transparent, blue, pink, etc., and can develop exclusive molds according to brand needs. The mold opening cost is low, the efficiency is high, and it quickly adapts to the differentiated packaging needs of the brand.
