1881 bottle preforms (usually 28mm PCO standard caliber) are the mainstream choice in the field of beverage packaging, and their advantages are mainly reflected in the four core dimensions of adaptability, production efficiency, cost control, and safety and environmental protection, as follows:
Super adaptability: covering multiple scenarios and category requirements
Compatibility of filling methods
It can meet the hot filling needs of fruit juice, tea drinks, etc., as well as adapt to cold filling/room temperature filling scenarios of mineral water, carbonated drinks, etc., without the need to change bottle preform types to switch product lines.
Widely applicable categories
It can be blown into bottles with various capacities ranging from 200ml to 5L, suitable for almost all mainstream beverages such as carbonated soft drinks, fruit juices, sports drinks, mineral water, and even used for some food packaging.
Bottle cap and equipment compatibility
Adopting standardized 1881 sealing specifications, it can adapt to various bottle cap types such as plastic caps and sports caps of the same standard, and is compatible with mainstream high-speed blow molding machines and filling production lines in the industry, without the need for additional equipment modification.
Efficient production characteristics: suitable for large-scale manufacturing
Adapting to high-speed production: Designed specifically for industrial mass production, it can match the operating rhythm of high-speed bottle blowing equipment, and with stable molding performance, it can significantly improve production line output and meet the large-scale supply needs of the beverage industry.
High molding flexibility: supports blowing multiple bottle designs and offers multiple weight specifications ranging from 12g to 53.5g, which can be flexibly adjusted according to bottle capacity and usage. It also supports color customization (such as transparent, light blue, etc.) to meet the packaging needs of different brands.
Convenient storage and transportation: As prefabricated components, they are easy to produce and store centrally, and their lightweight design reduces transportation weight and cost. Coupled with standardized packaging (such as pallets and woven bags), they can reduce losses during transportation.
Cost and quality balance: reduce costs while maintaining performance
Lightweight and material saving: Compared with traditional specifications such as PCO 1810, the neck height of 1881 preform is shorter (standard 17mm), reducing the amount of PET material while ensuring strength, directly reducing raw material costs, and reducing the weight of the final product.
Reliable core performance: PET material combines high transparency and toughness, which can enhance the attractiveness of product shelves; For carbonated beverage scenarios, it can withstand up to 4 atmospheres of CO ₂ pressure to avoid air leakage issues, while also having good barrier properties to extend the shelf life of the contents.
Safety compliance and environmental protection: in line with industry trends
Food grade safety assurance: Made from 100% new PET material, BPA free, and certified by international food safety standards such as FDA and REACH, it meets the hygiene standards of food packaging in multiple countries and can directly come into contact with beverages.
Green and recyclable: PET material has good recyclability, which meets global environmental policies and brand sustainability needs, and helps reduce the impact of packaging waste on the environment.
