According to Internet survey data, pet cosmetic bottles have been widely used in hot-filled carbonated cosmetics, health care products, fruit juices and other cosmetics. Netizens also praised and forwarded the praised pet cosmetic bottle. Many cosmetic processing factories also use this new type of pet cosmetic bottle to replace the old plastic packaging bottle. Cosmetic packaging material packaging briefly summarizes how to improve the heat resistance of hot-filled pet cosmetic bottles.
.Application of special mold design
The heat resistance of the hot-filled pet cosmetic bottle can be realized by adjusting the mold design. By adjusting the different positions of the shaping mold, the pressure in the bottle can be converted and output. For example, move the rectangular concave block on the pet cosmetic bottle mold to reduce the negative pressure generated after the pet bottle absorbs liquid and cool; adjust the mold design to set a concave shape on the neck or waist of the bottle to prevent the bottle from overheating and becoming an oval shape or design at the bottom of the bottle The petal shape counteracts the gas pressure that the bottle may experience.
.Increase the temperature of mold making
Improving the heat resistance of hot-filled pet cosmetic bottles can also be achieved by increasing the molding temperature. Some manufacturers will use the high temperature of the hot oil machine to increase the mold temperature so as to eliminate the internal stress generated by the preform during stretching. The existence of this kind of internal stress may cause the plastic mold to deform during forming, and the heating and elimination will help to improve the crystallinity of the plastic itself, thereby helping the pet cosmetic bottle to improve the ability of high temperature hydrothermal resistance.
.Improve the production process
Different production processes have a great influence on the heat resistance of hot-filled pet cosmetic bottles. In order to improve the high temperature and hydrothermal resistance of the bottle, it is necessary to start with improving the processing details. For example, for hot-filled pet cosmetic bottles with more complicated shapes, pay attention to increasing the blowing pressure during processing, so as to prevent the bottle from being poorly formed and resistant due to insufficient capacity. Thermal difference.
Now hot-filled pet cosmetic bottles are very popular in the market, and there are a large number of consultants everywhere asking where pet cosmetic bottles are available. Some manufacturers make hot-filled pet cosmetic bottles with better heat resistance. That is because they have improved the production process and raised the mold temperature during processing. At the same time, they have adjusted the molds where pressure may occur.
