Spraying with a spray bottle not only gives people a good experience in drug use, but also controls the amount of drug sprayed evenly, which brings great convenience to people. In recent years, with the development of China's economy and the improvement of people's living standards, China's spray industry has been vigorously developed, and the demand for spray bottle packaging in medicinal and cosmetic products has grown rapidly. Some insiders said that with the continuous advancement of technology, the market space for spray bottle packaging needs to be opened up.
It is understood that the current spray bottle packaging is limited to the cosmetics and pharmaceutical fields, and is used less in other fields. For example, in the field of pesticides with large demand, spray bottle packaging has not yet developed a reasonable product. At the same time of market vacancies, there are also huge market opportunities. In the future development, spray bottle packaging can excavate a wide range of fields such as pesticides, injecting new vitality and vitality into the development of 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 "take quality as the yardstick" and open up a broader market. So what are the quality of spray bottle packaging?
During the interview, the relevant technical personnel said that the most important thing in the spray bottle packaging is the quality of the nozzle. The quality of the nozzle directly determines the spray effect. However, from the current point of view, the quality of many nozzles on the market is worrying, and the nozzles often break down. After the nozzle is broken, things in the spray bottle, such as medicines, cannot be used, which causes great trouble for people.
For spray bottle manufacturers, in order to improve product quality and user experience, it is first necessary to start from the nozzle and control the quality of the nozzle. The author has learned that the spray nozzle of the plastic bottle is made of polyvinyl chloride. From the performance point of view, the polyvinyl chloride material has many advantages, but the flowability of the polyvinyl chloride melt is poor, and the shrinkage rate is seen from the molding. It is relatively low and molding is not very easy. Spray plastic bottles are prone to defects such as insufficient pouring and shrinkage during molding. The molding temperature is easy to decompose hydrogen chloride when the temperature is high. The injection speed is too fast, which will cause shrinkage. Therefore, it should be carefully controlled during molding. The molding temperature and retention 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 the large diameter nozzle should be selected.
