What is an airless bottle?
The contents of the airless bottle can be completely isolated from the air, so as to prevent the product from being oxidized and deteriorated due to contact with the air, and to breed bacteria, and to improve the product grade with its high-tech concept. The airless bottle prevailing on the market is made up of a cylinder into an ellipsoidal container plus a piston placed at the bottom.
The Development History Of Airless Bottles
Plastic Bottle Airless Packaging technology originated in the 1940s. Since polyester and polyethylene plastic films were successfully applied to commodity packaging in 1950, airless packaging technology has developed rapidly. The development of airless packaging in my country was in the early 1980s. Although it was later than developed countries in Europe, with the rapid development of airless packaging in my country, airless packaging technology is also continuously improving.
Airless packaging technology was first used in food packaging, and then gradually introduced into the pharmaceutical packaging and cosmetic packaging industries. In the initial stage, the airless packaging technology of cosmetics is basically mastered by foreign-funded enterprises. In the late 1990s, my country's airless packaging of cosmetics began to enter a period of rapid development, and related domestic companies also sprung up like mushrooms after rain. The following mainly explains the technology, classification and development of airless bottles in the cosmetics packaging industry.
Classification And Working Principle Of Airless Bottles
Taking cosmetics packaging as an example, the selection of Airless Bottles basically includes five elements: product compatibility, integrity of sealing, integrity of barrier, appearance appreciation, and physical properties in circulation. The integrity of the seal (that is, the airtightness of the package) is particularly important, because the active ingredients in most cosmetics are extremely volatile compounds, and many natural ingredients are easily discolored and deteriorated once exposed to air. High-end brands choose airless packaging for more than aesthetic considerations. Many high-end skin care brands have very advanced formulas and have specific requirements for airless packaging, so they need to be optimally protected.
The airless bottle body needs to be evacuated, the liquid distribution volume is uniform, and the internal space decreases with the reduction of the material body, which isolates the entry of external air, and the packaging appearance is beautiful. Consumers can distribute the products in the package at any position and angle, realizing a 360º all-round application without dead ends.
In practical applications, the airless pump and bottle system can be divided into three categories:
1. Piston airless system
This system is the most widely used one in the existing airless bottle body. A piston is installed inside the bottle body, and a closed space is formed between the bottle body and the press head. The material is stored in this space. By pressing the vairless pump to press the head, Promote the airless state in the space, and use the external atmospheric pressure to push the piston to move, so as to distribute the material through the airless pump outlet hole.
The key point of this technology is the cooperation between the piston and the wall of the bottle: the cooperation between the piston and the bottle wall should not be too tight or too loose. If it is too tight, the piston will not be able to move and the liquid cannot be pumped out. Therefore, it is limited to changes in packaging shape, and very regular packaging forms such as round or oval are common.
2. Tube type airless system
This system is based on the evolution of ordinary tubes, replacing the original cover with an airless pump. By pressing the airless pump button, an airless state is generated inside the tube, and the outer wall of the tube is compressed by atmospheric pressure to make the inner shrinkage deformed, so that the discharge body is distributed through the outlet hole of the airless pump. Because the hose wall is made of multi-layer materials and has a certain strength, the suction and sealing requirements of the airless pump are relatively high.
3. Inner bottle airless system
This system can be said to be a combination of the above two, with both a hard exterior and a soft interior. The liner material can be PE, aluminum bag, and other craft forms. The way it distributes the discharge body is similar to a tube-type airless system.
Different routes lead to the same goal, and the existence of different airless system structures must have its merits. Of course, every structure can't cover everything, and can adapt to infinitely changing use environments. Before determining the system structure of the vacuum bottle, it is necessary to do a good job in the preliminary research work, such as the viscosity of the material, the use environment, the compatibility with the material, and so on.
Material Classification of Airless Bottles
There is no specific procedure for the selection of raw materials for airless pumps and bottles. Mainly in the packaging development stage, the selection of materials is carried out according to the relevant requirements put forward by customers for products. For now, the plastic raw materials commonly used in airless bottles are as follows:
● Highly transparent materials (PMMA, AS, MS, MABS, PET, PETG, etc.);
● Semi-permeable material (PP, LDPE, LLDPE, silica gel, etc.);
● Solid color material (ABS, HDPE, rubber, etc.).
With the advancement of science and technology and the improvement of people's living standards, all walks of life attach great importance to green environmental protection, and the airless packaging industry is no exception. In recent years, recyclable PP vacuum bottles have developed very maturely. Biodegradable raw materials such as PET are also hot. This kind of raw material has good chemical resistance, but it is very sensitive to molds and molding processes, especially for products with thick walls, and it is difficult to form.
For the detection of airless bottles, the main focus is on three points: Airless Test, Ejection, and Number of Pumps.
The Development Trend Of Airless Bottles
At present, airless packaging dominates the entire cosmetic packaging market, and the airless packaging market is clearly led by vacuum bottles. Today's airless systems can deliver high-end and enhanced value to brands.
In addition to airless bottles tending to be green (there are two ways here: one chooses more environmentally friendly raw materials; the other chooses to reduce the number of parts that make up the whole product and minimize the weight of the package), there are some other new products on the market. development trend.
In terms of multi-purpose, double-layer bottles, double-headed bottles and other cosmetics and airless pump skin care products are emerging rapidly; in terms of appearance and shape, more concise and generous design will become the mainstream, and now the most cylindrical products on the market, Secondly, there are not many elliptical and square products, and there are not many strange-shaped products. It shows that consumers still agree with simple and generous products. Of course, in order for brand companies to cater to the needs of the brand, that's another matter.
In terms of packaging texture, the single-layer airless bottle is gradually turned into a double-layer bottle design to highlight the layered and high-end sense of packaging. In order to attract more consumers and win the attention of more consumers, rich and varied secondary processing technology will become the first choice. A well-coordinated package will exude a unique charm. The secondary processing technology will also usher in another technological revolution and innovation!
