Rookie in the packaging industry – Plastic Airless Bottle

A vacuum flask refers to a container that can isolate gas from the outside temperature or a container that isolates external bacteria. Its contents can be completely isolated from the air to prevent the product from oxidizing and deteriorating due to contact with the air, and breeding bacteria, and it uses its high-tech concept to upgrade the product level. The vacuum bottle in the market is composed of a cylinder into an ellipsoid container and a piston placed at the bottom. Its design principle is to use the contraction force of the spring to prevent air from entering the bottle, resulting in a vacuum state, and to use atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough force, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to move forward due to excessive resistance; on the contrary, if the piston is to move forward easily and it is prone to material leakage, Therefore, airless bottles have very high requirements for the professionalism of manufacturers.

Introduction of airless bottle of cosmetic packaging material knowledge

The introduction of the airless bottle conforms to the latest development trend of skin care products and can effectively protect the freshness of the product. However, due to the complicated structure of the vacuum bottle and the high cost, the use of vacuum bottle packaging is limited to a limited number of categories of products, which cannot be fully deployed on the market to meet the needs of different grades of skin care products.

While attaching importance to the protection and decoration of cosmetic packaging materials, manufacturers began to focus on the development of the functionality of skin care product packaging, making the concept of “fresh”, “natural” and “preservative-free” worthy of the name.

Vacuum packaging technology is a new concept with absolute advantages. This packaging technology has helped many new brands and new formulas go on the market smoothly. Once the vacuum packaging is assembled, from filling the packaging to the consumer’s use process, almost minimal air can enter the container, contaminate or decompose the contents. This is the advantage of vacuum packaging-it provides a safe packaging empty for products, avoids contact with air, reduces the most likely change and oxidation, especially the delicate natural ingredients that need to be protected, when avoiding the addition of preservatives Among the calls, vacuum packaging is more important for extending the shelf life of products.
