1810 preform (usually 28mm PCO standard caliber, also known as "long neck" preform), as a classic packaging preform, still occupies an important position in the beverage packaging field in many parts of the world due to its mature and reliable performance, wide adaptability to various scenarios, and stable sealing characteristics. Its core advantages are as follows:

Solid and reliable performance: suitable for high demand filling scenarios

Super pressure resistant sealing

The neck design (about 21mm in height) is thicker, with longer internal threads and tight bite, which can effectively withstand the internal pressure of carbonated drinks and other carbonated drinks (suitable for high CO₂ content scenarios), greatly reducing the risk of air leakage. The sealing reliability has been verified by the market for decades.

Stable and controllable molding

Using mature production processes, the weight of the preform is uniform and the wall thickness is consistent. Combined with the high toughness of PET material, the molding effect is stable during the blowing process, which can reduce the scrap rate caused by defects in prefabricated parts and ensure the quality of mass production.

Compatible with hot and cold scenarios

The basic version can adapt to cold filling needs such as mineral water and carbonated beverages, while the specialized version that has undergone crystallization treatment can also meet hot filling scenarios such as fruit juice and tea beverages. There is no need to frequently change bottle preform types to flexibly switch product lines.

Wide range of adaptability: compatible with devices and multi category requirements

Strong equipment compatibility: As a classic standard that has been used for more than 20 years, 1810 bottle preforms can adapt to the vast majority of mainstream blow molding machines and filling production lines worldwide, especially suitable for small and medium-sized factories with mature equipment, and can be put into operation without additional equipment modification, reducing upgrade costs.

Comprehensive category coverage: It can be blown into various capacity bottle types ranging from hundreds of milliliters to several liters, widely used in carbonated soft drinks, mineral water, fruit juice, sports drinks and other beverages, and even extended to some food and daily chemical packaging scenarios, with flexible adaptability.

Flexible bottle cap adaptation: Adopting standardized 1810 sealing specifications, it can be matched with various types of same standard bottle caps such as plastic caps and sports caps, and supports customized bottle cap designs to meet the packaging needs of different brands.

Deep market foundation: adapted to specific demand scenarios

Mature and convenient supply chain: As a traditional mainstream specification, the production supply chain of 1810 bottle preforms covers the world, making raw material procurement, production delivery, and after-sales maintenance more convenient. It can also provide diversified weight options (12g to 64.5g, etc.) to meet the needs of different capacity bottle types.

Regional demand adaptation: In markets such as Africa and South America where packaging costs are less sensitive and performance stability is more emphasized, 1810 bottle preforms are still widely used due to their mature and reliable characteristics, especially favored by small and medium-sized beverage enterprises.
