The performance requirements of Plastic bottle caps mainly include the following aspects:
Sealing performance: Plastic bottle caps must have good sealing performance to prevent liquid leakage. This usually involves requirements for the tightness, pressure resistance and durability of the cap.
Leak-proof performance: Leak-proof performance is also one of the important properties of Plastic bottle caps. The bottle cap is required to effectively prevent the leakage of liquid and gas during normal storage and use.
Impact resistance: Plastic bottle caps need to have certain impact resistance to ensure that they can withstand a certain amount of external pressure and impact during transportation and storage, and are not easily deformed or broken.
Aging resistance: Plastic bottle caps should have good aging resistance to ensure that during long-term use, their performance will not be significantly reduced due to factors such as ultraviolet rays and temperature changes.
Chemical resistance: Plastic bottle caps that need to be exposed to chemical substances need to be chemically resistant to ensure that they will not be corroded by chemicals or produce harmful substances during use.
Food safety: Since Plastic bottle caps may be in direct contact with food, they must comply with relevant food safety standards, such as non-toxic, no odor, etc.
High temperature resistance: Some plastic materials can maintain their performance under certain high temperatures, which is very important for containers that require high temperature sterilization.
Wear resistance: The bottle cap should have a certain degree of wear resistance to cope with daily opening and closing actions and prevent excessive wear.
Pressure resistance: In some application scenarios, Plastic bottle caps need to withstand a certain amount of external pressure, which requires the bottle cap to have a certain pressure resistance.
Appearance quality: The appearance quality of the bottle cap is also part of the performance requirements, including surface smoothness, color uniformity, etc., which all affect the overall quality and brand image of the product.
The above are some of the main aspects of the performance requirements for Plastic bottle caps.
