Introduction to 2925 Bottle Cap

I. Product Structural Design Features and Core Advantages

1.1 Core Structural Design Highlights

The 2925 cap adopts the industry-mature composite sealing structure of "olive-shaped inner plug + outer plug double sealing + three-section thread". The core advantage of this structural design is that it can achieve full-dimensional sealing of the bottleneck without adding an additional inner liner. It not only avoids the quality risk of inner liner detachment, but also simplifies the production process, while fully meeting the sealing pressure requirement of the national standard for non-carbonated beverage caps.

The tamper-evident band is the core mandatory structure of the product, adopting a bridge-connected design. The connecting bridge will break accurately when opening, and cannot be restored after breaking. It can not only effectively prevent the product from being opened twice and ensure beverage safety, but also allow consumers to intuitively identify whether the product has been opened. It is an important design for anti-counterfeiting and anti-tampering of food packaging, fully complying with the core requirements of the national standard for food packaging safety.

The 72 knurl lines on the outer side of the cap body are the optimal design quantity in the industry. The tooth spacing is uniform and the depth is moderate, which can not only effectively improve the friction between the hand and the cap body, allowing different groups such as the elderly and children to open it easily, but also not reduce the strength of the cap body due to too many tooth lines, achieving a dual balance between "opening convenience" and "product structural strength".

1.2 Material Selection and Hygiene Compliance Requirements

The core production raw material of the 2925 cap is food-grade high-density polyethylene (HDPE), which is an environmentally friendly food-grade plastic belonging to the polyolefin category. The selection of this material fully complies with the mandatory requirement of "taking polyolefin as the main raw material" in the GB/T17876-2010 national standard. No recycled materials or reclaimed materials are added, ensuring the food contact safety of the product from the source.

Both raw materials and finished products must meet dual national hygiene standards: first, the raw materials must comply with GB9687 "Hygienic Standard for Polyethylene Molded Products for Food Packaging"; second, the raw material additives must strictly follow GB9685 "Hygienic Standard for the Use of Additives in Food Containers and Packaging Materials"; before leaving the factory, the finished products must complete all-item testing in accordance with GB/T5009.60, and the content of harmful substances such as heavy metals and volatile substances must meet the food-grade qualified standard, without any hygiene and safety hazards.

II. Product Application Scenarios and Market Adaptability Characteristics (Supplemented with Complete Non-technical Core Content)

2.1 Core Applicable Categories and Packaging Matching

The 2925 cap is a "special cap for non-carbonated beverages", corely adapting to the packaging scenarios of various room-temperature and cold-filled bottled beverages, specifically including: bottled water categories such as drinking purified water, natural mineral water, and distilled water; non-carbonated beverage categories such as fruit juice drinks, fruit-flavored drinks, sugar-free tea drinks, and herbal plant drinks; it can also adapt to the packaging needs of some food-grade bottled products such as condiments and oral liquids.

In terms of packaging bottle type matching, this cap is only suitable for lightweight PET material packaging bottles, especially lightweight thin-walled PET bottles treated with nitrogen, which is the mainstream choice of bottled water enterprises. It is not suitable for hard packaging bottles such as glass bottles and metal bottles, nor can it be adapted to beverage production lines with hot-filling process, which is also the core application boundary of the product.

The Jeepine Cap Compression Machine CCM-YSZG54 produced by Guangzhou Jeepine intelligent Compression Molding Machine Co.,Ltd can produce 2925 caps at a speed of 100,000 pieces per hour. This cap can not only adapt to high-speed filling production lines of thousands of pieces per minute, meeting the efficiency requirements of large-scale industrial production of beverage enterprises, but also balance the aesthetics and practicality of product packaging, becoming the preferred product for beverage enterprises' packaging upgrade.

In addition to the Chinese market, the specifications of this cap are also consistent with the general standards of overseas bottled water markets such as Southeast Asia and the Middle East. Some export-oriented beverage enterprises also take it as a core packaging supporting product, with certain international market adaptability. It is a general-purpose product that meets the needs of both Chinese and overseas markets.

III. Production Process, Inspection Specifications and Storage/Transportation Requirements

3.1 Mainstream Production Processes and Production Control

There are two mainstream production processes for the 2925 cap: compression molding process and injection molding process. Both processes comply with the requirement of "formed by injection molding, hot pressing or other processes" in the national standard, without process compliance issues. Among them, compression molding is the industry-recommended process. The finished cap has higher density, more stable dimensional accuracy, and no shrinkage or bubble defects on the appearance, making it the preferred process for leading beverage brands; the injection molding process has high production efficiency, suitable for small and medium-sized batch orders, and the finished product quality also meets the national standard requirements.

The core control points in the production process are divided into two aspects: first, raw material control. All raw materials must provide food-grade test reports, and the use of non-food-grade raw materials and recycled materials is strictly prohibited; second, process parameter control. Strictly control the molding temperature, pressure, and cooling time to avoid dimensional exceeding, structural defects and other quality problems caused by parameter deviations, ensuring the consistency and compliance of each batch of products.

3.2 Finished Product Inspection Rules

▶ Batch Formation Rule: Products continuously produced with the same batch of raw materials, the same production equipment, and the same production process are regarded as one inspection batch, and the maximum output of a single batch shall not exceed 1.2 million pieces.

▶ Inspection Classification and Mandatory Inspection Items

Factory Inspection: It is a mandatory item for each batch. The core tests include appearance quality (full molding, no impurities, no material shortage, intact tamper-evident band), dimensional accuracy, and printing pattern adhesion. All items must be qualified before leaving the factory.

Type Inspection: When raw materials are replaced, production processes are adjusted, production is resumed after suspension for more than 6 months, or quality problems are reported in the market, a full-item type inspection must be performed, including all national standard indicators such as physical and mechanical properties and hygiene performance.

▶ Sampling and Judgment Standard: Strictly implement the double sampling plan in GB/T2828.1. 315/630 pieces are sampled for appearance, and 100 pieces are sampled for sealing performance. If any item is unqualified, the batch is judged unqualified. If any item of hygiene performance fails to meet the standard, the entire batch of products is prohibited from leaving the factory and being sold.

3.3 Packaging, Transportation and Storage Specifications

Product packaging must be completed in a clean, dust-free, and sterile workshop environment. The finished products are subpackaged in food-grade transparent sealed bags and then put into corrugated cartons. There are no sharp debris in the cartons to avoid scratching the surface of the caps during transportation. The outer side of the packaging carton must clearly mark the product name, specification (2925), quantity, manufacturer, production date, shelf life and other information, and paste storage and transportation graphic marks such as moisture-proof, sun-proof, and handle with care in accordance with GB/T191, facilitating warehouse and transportation control.

For the transportation link, clean, dry, and odorless transportation vehicles shall be selected to avoid sun exposure, rain, high-temperature exposure, and low-temperature freezing. Mixed transportation with toxic, harmful, and odorous items is strictly prohibited to prevent product contamination. For the storage link, the products shall be stored in a clean and ventilated warehouse at 18℃-38℃. There is no water accumulation, mildew, or odor in the warehouse. If the storage environment temperature is lower than 18℃, the caps shall be preheated to room temperature 24 hours in advance before use to avoid material embrittlement and opening difficulties caused by low temperature. The standard storage shelf life of the product is 12 months.
