3025 and 2925 PET preforms belong to standardized prefabricated parts with a diameter of 30mm. With precise scene adaptability, lightweight cost advantages, and stable production performance, they are widely used in the field of small and medium-sized beverage packaging. The core advantages are concentrated in the following four dimensions:

Scene focused adaptation: precise coverage of small and medium-sized capacity requirements

Core category highly matched

Designed specifically for mainstream small and medium-sized packaging of 300-1500ml, widely compatible with basic beverages such as mineral water, carbonated drinks, functional drinks, and can also be used for flavored drinks such as fruit juice and low alcohol beverages. The 2925 specification is particularly common in special demand scenarios such as nitrogen water.

Flexible and compatible filling scenarios

The basic model is compatible with cold filling and room temperature filling processes, and after process optimization, it can meet some medium temperature filling needs. It can achieve multi category production line reuse without changing bottle preform types, and is suitable for flexible production needs of small and medium-sized brands.

Clear and controllable capacity gradient

By combining multiple weight specifications ranging from 12.5g to 28g, a complete capacity coverage system is formed - for example, 12.5g 2925 preforms can be adapted to 300-530ml portable packs, and 28g 3025 preforms can support 500-1500ml household shared packs, accurately matching different consumption scenarios.

Structural design advantages: Balancing performance and cost

Significant lightweight and material saving characteristics: adopting an optimized neck structure design, the single weight of 2925 preforms can be as low as 2.4-2.5g, while the basic version of 3025 preforms weighs about 3.9g. Compared with traditional large-diameter preforms, it significantly reduces PET material consumption, directly reducing raw material costs and transportation weight.

Double reliability of sealing and molding: Standardized 30mm caliber with precision thread design, compatible with screw caps, sealing caps, etc. of the same specifications, tightly bite and anti vibration, effectively blocking air intrusion; At the same time, strict control of the process ratio (≤ 45) is in line with the flowability characteristics of PET materials, resulting in strong molding stability.

Appearance and texture adaptation requirements: Made from food grade PET raw materials, the surface of the bottle preform is smooth and flawless. After blowing, the transparency and glossiness are excellent, which can intuitively display the color of the beverage. It combines the texture of glass and the anti drop properties of plastic, enhancing the attractiveness of the shelf.

Production efficiency optimization: adapting to scale and flexible manufacturing

Efficient adaptation to mainstream equipment: Produced using mature injection molding technology, with high weight and dimensional accuracy, it can be matched with medium and high-speed bottle blowing production lines with a bottle blowing success rate of over 99%, significantly reducing the scrap rate.

Controllable full chain cost: Lightweight design not only reduces raw material consumption, but also lowers storage and transportation costs - standardized stacked packaging can increase storage density, lightweight characteristics reduce logistics energy consumption, and with a mature supply chain system, achieve cost optimization from production to delivery.

Flexible and fast customization response: Supports multi color customization such as transparent and light blue, and can adjust the weight and bottle shape adaptation parameters according to brand needs. The mold opening cycle is short and the cost is controllable, and customized production delivery can be completed within 4-6 weeks, quickly responding to the market's new product iteration needs.

Outstanding green and recyclable properties: PET material has excellent recyclability, and the preform can be produced with recycled PET (PET) material, which is in line with global environmental policy trends; At the same time, lightweight design reduces the carbon footprint throughout the entire lifecycle, helping brands achieve sustainable development goals.

Mature and stable supply chain: As a standardized specification, its production supply chain covers a wide range, with convenient raw material procurement, mold matching, and after-sales maintenance, and is suitable for export needs in multiple regions. It is particularly popular in emerging markets such as the Middle East and Africa.
