Protective Plastic Bottle End Caps

protective plastic bottle end caps

Plastic bottle end caps are also known as plastic bottle caps, plastic caps, plastic bottle cap sealer, plastic cap seal, plastic flip top cap, plastic end cap, plastic caps for bottles, screw cap plastic bottle, plastic screw cap, plastic spout cap, cap case plastic, inner plastic cap, plastic bottle safety cap, valve caps plastic, plastic lock cap, plastic bottle with twist cap etc.

Plastic bottle caps are a common packaging form for bottle packaging, especially in the field of beverages. They can be divided into carbonated beverage bottle caps and non-carbonated beverage bottle caps according to their uses. Generally, polyolefin is used as the main raw material, which is processed by injection molding, hot pressing or other processes. Plastic anti-theft bottle caps are not only required to be easy for consumers to open, but also need to avoid leakage problems caused by poor sealing performance.

Plastic cap seal is a closure for the top opening of a bottle. A cap is sometimes colourfully decorated with the logo of the brand of contents. Plastic caps are used for plastic bottles; plastic caps are commonly made from PE or PP. Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic from the bottle.

Plastic screw cap is a mechanical device which is screwed on and off of a "finish" on a container. Either continuous threads or lugs are used. It must be engineered to be cost-effective, to provide an effective seal (and barrier), to be compatible with the contents, to be easily opened by the consumer, often to be reclosable, and to comply with product, package, and environmental laws and regulations.

Performance of plastic lock cap:

1. There is an annular leak-proof ring on the inner wall of the top of the bottle cap;

2. The lower end of the bottle cap is connected to an anti-theft ring through the tensile reinforcement;

3. At the same time, there are several sheet-like gyratory tension wings evenly distributed on the inner wall of the anti-theft ring

The bottle cap designed in this way has the characteristics of firm sealing, good leak-proof and anti-theft performance, safe and convenient use, can effectively prevent the liquid in the bottle from being polluted by bacteria, and can ensure that various beverage packages meet the national health standards and other characteristics.

The sealing performance of plastic bottle safety cap  is the main factor affecting packaging leakage and product deterioration. By reasonably controlling the sealing performance, it can ensure its good opening performance and avoid leakage.
