Material modification improves toughness: By adding toughening agents to PET plastic, its impact resistance can be effectively improved. If thermoplastic elastomer is added, it can form an island structure with PET. When impacted, the elastomer particles can cause silver streaks and shear bands, absorb impact energy, thereby enhancing the toughness of plastic bottles and reducing the risk of collisions during transportation and storage. And the chance of rupture.
Optimize bottle structure design: A reasonable pet plastic bottle structure can significantly improve impact resistance. For example, use a design with thicker bottle walls, especially at the bottom and shoulders, which are prone to impact. Reinforcing ribs can also be designed to be evenly distributed on the surface of the bottle to enhance the overall strength. For example, some beverage bottles are designed with annular reinforcing ribs around the bottle body, which effectively improves the bottle's impact resistance.
Improve the design of bottle mouth and cap: pet plastic bottle bottle mouth and bottle cap are places prone to breakage. Optimize the shape and thickness of the bottle mouth so that it fits closely with the bottle cap and has certain impact resistance. At the same time, choose the appropriate cap material and sealing method to ensure that the cap will not fall off or cause the bottle mouth to break when impacted. For example, using a screw-on bottle cap and adding a sealing gasket can enhance sealing and impact resistance.
Surface treatment to enhance hardness: Surface treatment of pet plastic bottles, such as coating treatment. Coat the bottle surface with a layer of coating with high hardness and good wear resistance, such as nano-ceramic coating. This not only increases the surface hardness of the bottle, but also resists external impact to a certain extent and protects the bottle from damage.
Choose appropriate packaging materials: Use appropriate packaging materials to protect plastic bottles during transportation and storage. For example, use foam plastic, bubble wrap and other cushioning materials to wrap the pet plastic bottle. These cushioning materials can act as a buffer when subjected to impact, reducing the impact of the impact on plastic bottles.
Standardize transportation and storage operations: It is also important to establish reasonable transportation and storage practices. During transportation, avoid rough loading and unloading and handle with care. When storing, place pet plastic bottles on stable shelves to avoid stacking them too high and causing the bottom bottle to burst due to pressure. At the same time, the temperature and humidity of the storage environment are controlled to prevent environmental factors from affecting the performance of plastic bottles.
Conduct impact resistance testing: During the production process, pet plastic bottles are subjected to strict impact resistance testing. Test the impact resistance of pet plastic bottles by simulating impact scenarios during transportation and storage, such as drop tests, collision tests, etc. Based on the test results, the production process and design are adjusted in a timely manner to continuously optimize the impact resistance of plastic bottles to meet actual use needs.
