As a classic sealing component in the packaging field, ordinary screw caps focus on ultimate sealing, structural reliability, and cost-effectiveness. With mature technology and extensive adaptability, they are still the mainstream choice today, as follows:
Core performance: Reliable sealing, ensuring quality
High sealing freshness lock
By tightly interlocking with the bottle body through threads and using built-in sealing pads (such as PE pads, silicone pads), it can effectively block air, moisture, dust, and microbial invasion, especially suitable for carbonated beverages, fruit juices, and other categories that require high sealing performance, extending the warranty period of the contents.
Anti leakage and pressure resistance
The threaded interlocking structure is stable and can withstand vibration, inversion, and stacking pressure during transportation, greatly reducing the risk of liquid leakage. It is suitable for long-distance transportation needs of various liquid products such as mineral water and edible oil.
Durable and damage resistant material
Food grade PP or PE raw materials are selected, which have good toughness and impact resistance, can withstand collisions and compressions during filling and handling, are not easily deformed or cracked, and reduce the supply chain damage rate.





Scenario adaptation: Compatible with all categories, efficient production
Wide adaptability range: covering mainstream calibers such as 28mm, 38mm, 55mm, etc., it can be used for almost all packaging scenarios such as mineral water, carbonated beverages, fruit juice, alcohol, sauces, daily chemical products, etc., with strong compatibility.
Compatible with high-speed production: adopting standardized thread design, it can seamlessly adapt to mainstream automatic capping equipment in the industry, with fast capping speed and high stability, which can meet the production needs of tens of thousands of bottles per hour and ensure production line efficiency.
Easy to use and operate: The operation logic of unscrewing and tightening is intuitive, without the need for learning costs, suitable for users of all ages, especially for daily use scenarios such as home and catering, and the opening and closing times are not limited, and can be repeatedly sealed.




Cost and safety: economical and practical, compliant and reassuring
Outstanding cost economy: simple structure, mature production technology, low raw material consumption, both mold cost and single piece production cost are lower than complex structures such as flip covers and sports covers, which can effectively control the total packaging cost and adapt to mid to low end and mass consumer categories.
Safety and compliance guarantee: Using 100% new food grade raw materials, free of harmful substances such as BPA and plasticizers, certified by authoritative authorities such as FDA and SGS, it can directly come into contact with food and beverages and meets global food packaging safety standards.
Mature and stable supply chain: As a standardized component, there are numerous manufacturers with a wide coverage of the supply chain. The procurement of raw materials, production delivery, and after-sales maintenance are convenient, and the inventory turnover rate is high, which can quickly respond to order demands.
