JEEPINE Dairy Bottle Cap Production Solution
1. Introduction to Dairy Bottle Caps
Plastic caps for dairy bottles are essential accessories that interface directly with the product. They provide critical functions such as gas barrier performance, moisture resistance, and contamination prevention. On one hand, they prevent the contents from leaking out; on the other, they block foreign particles from entering, ensuring product quality and safety

3. Cap Manufacturing Process
The JEEPINE dairy cap machine is a fully automatic compression-molding system featuring high-speed rotary molds. It produces plastic caps for water, pharmaceutical, daily-chemical, and alcoholic beverage bottles. The process is as follows:
Heat and melt PE/PP pellets, then extrude a metered flow via the screw
A cutting disk slices the molten material and distributes it evenly to each cavity
High-speed rotary compression in the mold forms the cap, which is cooled and ejected
4. Key Advantages
High Stability: Integrated turntable + dual-pump hydraulics + PID control enable low-pressure clamping and high-pressure forming for stable operation
High Productivity: Advanced feed system + multi-cavity rotary compression + vacuum-assisted ejection increase throughput
Energy Saving: Low-temperature polymer melting reduces heating and cooling energy consumption
Material Efficiency: Intelligent temperature control + precise cutting ensure consistent weight and minimize waste
Intelligent Safety: Real-time monitoring, alarms, self-diagnosis, and protection functions
Hygiene & Cleanliness: Integrated cap forming, blowing, filling, and capping with inline transfer reduces manual contact

JeePine provides diversified cap solutions covering a wide range of industries such as food, beverage and pharmaceuticals:
Aerated cap
Such as 2622 CSD CAP for carbonated beverages.
Static water cap
Such as 2622 WATER/CAF CAP, for purified water or mineral water.
Pharmaceutical caps
e.g. 28mm caps for pharmaceutical products.
Special application caps
e.g. white wine inner cap, toothpaste cap, etc.
Each solution specifies in detail the cap raw material (HDPE), bottle mouth size (e.g., 26mm, 28mm, etc.), sealing structure (inner stopper + outer stopper), weight (e.g., ranging from 1.1g to 6.9g), and application areas (e.g., carbonated beverages, water, fruit juices, dairy products, etc.), which allows for lightweighting, diversification, customization, and the development of new cap styles to ensure that we meet the various needs of our customers.
