It is understood that the spray bottle packaging is Sprayer Bottles currently limited to cosmetics and pharmaceuticals, and is less used in other areas. For example, in the field of pesticides with relatively high demand, reasonable products have not been developed for spray bottle packaging. At the same time when the market is vacant, there are actually huge market opportunities. In the future development, spray bottle packaging can tap into broad fields such as pesticides, injecting new vitality and vitality into the industry. But for the development of every industry, quality is an eternal topic. For the development of spray bottle packaging, quality is also crucial. Enterprises need to "use quality as the criterion" to develop a broader market. So from what aspects can the quality of spray bottle packaging start?During the interview, the relevant technicians said that the most important thing in the spray bottle packaging is the quality of the nozzle, which directly determines the spray effect.
But from the current point of view, the quality of many nozzles on the market is worrying, and the nozzles often break down. After the spray head breaks down, the contents of the spray bottle, such as medicines, cannot be used, which causes great trouble to people.For spray bottle manufacturers, in order to improve product quality and user experience, they must first start with the nozzle and control the quality of the nozzle. The author learned that the spray head of the plastic spray bottle is made of polyvinyl chloride. From the performance point of view, the polyvinyl chloride material has many advantages, but from the perspective of molding, the flow of the polyvinyl chloride melt is poor, and the shrinkage rate Relatively low, molding is not easy. Spray plastic bottles are prone to defects such as insufficient pouring and shrinkage during molding. Hydrogen chloride is easily decomposed when the molding temperature is relatively high.
Shrinking when the injection speed is too fast ... Therefore, you should pay attention to control when molding. The molding temperature and residence time, the pouring system should be thick and short, the feed port section should be larger, the cooling time should not be too fast, and choose a large-diameter nozzle.In addition, the spray nozzles of plastic bottles have relatively high requirements on the accuracy of the structure and dimensions of plastic parts. To obtain qualified plastic parts, in addition to rationally selecting raw materials for plastic parts, enterprises should also consider the structural manufacturability of plastic parts, because the structural manufacturability of plastic parts has a direct relationship with the design of molds.
Only plastic parts The design meets the requirements of the molding process in order to design a reasonable mold structure, which can prevent defects such as bubbles, shrinkage, depressions and cracks during molding. Not only that, it can also improve the production efficiency of spray plastic bottles. Relevant technicians emphasized that when designing the plastic parts of the spray head of the spray plastic bottle, the surface of the part should be free of defects and burrs, and the phenomenon of insufficient pouring should not occur.With the continuous development of the market, the use scenarios of spray bottle packaging will become more and more diverse. In addition to the cosmetics and pharmaceutical markets, many daily cleaners have also begun to use spray bottle packaging. Therefore, it is very important to improve the quality of spray bottle packaging. In the design and production of spray bottles, in addition to ensuring the quality of the spray head, other aspects are also worth noting. For example, the use period of spray plastic bottles is generally longer. During repeated use, the surface of plastic bottles is prone to breed some bacteria, which affects the health of users.
