The combination of POF shrink film and cosmetic aseptic packaging design

The combination of POF shrink film and aseptic packaging design of cosmetics: In the process of cosmetics use, it is known that using a cotton swab instead of fingers to take the cream is clean and saves the amount. In order to be more convenient and hygienic to use, more and more cosmetics are doing their homework on packaging, such as vacuuming, compression pumps, aseptic chambers... Under these extremely design appearances, the tightness of the packaging needs to be investigated. They are Isn't it really sterile?　　Vacuum packaging cannot guarantee sterility　　 Nowadays, there are more and more cosmetics in vacuum packaging, but can vacuum packaging really be sterile? Pof shrink film manufacturer-plastic bag learned that the purpose of vacuuming is only to delay product deterioration. When the finished cosmetic product is filled into the bottle, the gas will be pumped out through the machine, making the bacteria lose the breeding ground for survival. But whether there are bacteria in it depends on the production process of the cosmetics and the preservation conditions during use. The process of making cosmetics is not a vacuum environment, so only by purchasing formal and qualified cosmetics can we guarantee hygiene and safety. To avoid the growth of bacteria during use, preservatives are added to the raw materials at the beginning, but they will still deteriorate if they are not stored properly.　　 POF heat shrinkable film manufacturers say that cosmetics contaminated by bacteria are as terrible as expired cosmetics, which can cause acne in the least, and cause suppuration and infection, especially for sensitive skin. If the cosmetics start to turn yellow or the smell becomes pungent, it means that the product has deteriorated and can no longer be used. The 　　 sterile cabin design is more conducive to bacteria prevention. 　　pof shrink film The author visited the market and found that most of the seemingly sealed packages are not vacuumed. The shrink film manufacturer said that to judge whether it is a vacuum bottle, just look at the pores at the bottom of the bottle, if there is one, then it is, if there is no, then it is not. After covering the air holes at the bottom of the bottle, the bottle pump cannot be squeezed. Most air-tight packages are evacuated after production, not really evacuated. The consumer's common spray is designed to pressurize the bottle with nitrogen, not a vacuum.　　 In addition, the 'compression pump' is not the basis for judging whether it is vacuum, the key is whether there are pores at the bottom of the bottle. If there is no air hole, it is a general compression pump design, in order to squeeze the liquid out by pressure. Another 'sterile cabin' design, which claims to be safer than vacuum, is the hose and special bottle cap design. With this design, the body of the hose can be seen to shrink gradually after use. When it is used for squeezing, because it will not pump air down, it will not allow the emulsion to flow back and prevent contamination.　　 also pay attention to preservation of cosmetics. 　　The bottle can itself is not a vacuum design and cannot be changed, but if you adopt a proper preservation method, you can effectively extend the use time of the cosmetics. Shrink film manufacturers recommend that high-activity skin care products such as vitamin C, amino acids, protein, and vitamins should be placed in a dark place as much as possible. If they are 'stocked　　 If you want to save the remaining capsule care products, you can use a vacuum compression bag to pack all the capsules, and then use a vacuum pump to drain the air, which can effectively extend the use time. It is worth mentioning that many people like to put skin care products in damp bathrooms. This is a very serious mistake. Except for the general cleaning products with no nutritional value, the skin care products containing unsaturated fatty acids will be caused by heat, Moisture makes the active ingredients lose their proper function.
