Another article to seriously look at, seriously remember the article, cosmetic packaging material knowledge seems to never finish learning, you see, with the type of division, right, there are lipstick tubes, lotion bottles, powder cases, dozens of cosmetic packaging material types need to familiarize themselves with the memorization, and different materials, process combinations, and will extend the new knowledge, so in the cosmetic packaging material industry, or to continue to learn in order to make progress ah.

Speaking of vacuum flasks, I've had previous experience inCosmetic packaging knowledge: vacuum bottle introductionThis article has done a brief introduction to thatThe contents of the vacuum bottle can be completely isolated from the air, to avoid product oxidation and deterioration due to contact with air, breeding bacteria, and with its high-tech concept to enhance the product grade. Vacuum bottle prevailing in the market is composed of a cylinder into an ellipsoid container plus a placement of the bottom of the piston. Its design principle is to use the contraction force of the spring, and do not let the air into the bottle, resulting in a vacuum state, and the use of atmospheric pressure to promote the bottom of the bottle piston forward.?However, due to the spring force and atmospheric pressure can not give enough power, so the piston can not be too tight with the bottle wall, otherwise the piston will not be able to rise forward due to excessive resistance; on the contrary, if you want to make the piston easy to move forward and prone to leakage, so the vacuum bottle on the professionalism of the manufacturer's requirements are very high.

Vacuum Packaging Technology

Vacuum packaging technology is a new concept with absolute advantages. This packaging technology has helped many new brands and formulations come to market. Once vacuum packaging is assembled, from filling to consumer use, there is very little air that can enter the container and contaminate or break down the contents. This is the advantage of vacuum packaging?-?It provides a safe packaging vessel for products to avoid contact with air, reducing the occurrence of highly probable changes and oxidation, especially the urgent need to protect the delicate natural ingredients, in order to avoid the addition of preservatives in the call, vacuum packaging for the extension of the shelf life of the product is even more important.

Vacuum-packed products are different from the common straw-type standard pumps or spray pumps, vacuum packaging is the use of the principle of separation of the inner chamber, the contents of the extrusion discharge. When the inner membrane sheet moves upward to the inside of the bottle, forming a pressure, at this time the contents are present in close proximity to the bottle.100percent vacuum. The other type of vacuum is the use of a flexible vacuum bag, placed inside a rigid container, and both are used in almost the same concept. The former is widely used and is an important selling point for brands because it uses fewer resources and can be recognized as a?"Green."

Vacuum packaging also provides precise dosage control. Once the outlet holes and specific vacuum pressure have been set, the dosage is precise and quantitative, regardless of the shape of the supporting indenter. Therefore, the dosage can be adjusted from a few microliters to a few milliliters by changing a certain component, depending on the needs of the product.

Product freshness and hygiene are key values that advocate vacuum packaging, and once the contents have been removed, there is no way to put them back into the original vacuum package. As the design principle is to ensure that each use is fresh, safe and worry-free, the internal mechanism of our products, with no spring rust to worry about, will not contaminate the contents.

Consumers recognize the value of vacuum products. Compared with the general standard pumps, sprays, straws, and other packaging components, vacuum packaging, the use of smooth, fixed dosage, high-grade appearance, so that it occupies a large market for luxury products.
