In the current Chinese aerosol market, binary packaging is increasingly sought after by the market. In fact, packaging technology has been maturely used abroad for 30 to 40 years, but we are only late. Today we will briefly introduce some basic understanding of binary packaging.
Binary packaging English name Bag-on-Valve, English abbreviation BOV.
Binary packaging relies on the development of modern technology in the market to promote the progress of aerosol applications in the cosmetic, pharmaceutical and food industries. At the same time, many small fire extinguishers are also using binary packaging. Binary aerosols can be applied to liquids and viscous products with a wide range of applications. For example, our commonly used hair dyes, styrofoam after shaving, deodorant, insect repellent, sunscreen spray, hair removal spray and so on.
Advantages of binary packaging
1. Easy to use, making consumers happy to use;
2. It can spray at any angle and;
3. The ejection rate can reach more than 99%;
4. The service life of oxygen-sensitive products and sterile products can be longer;
5. It can reduce the addition of preservatives;
6. Environmentally friendly propellant, reduce or eliminate the flammability of the product;
7. The spray state can be uniform and controllable;
How Binary Packaging Works
Binary packaging is an aerosol composed of a valve and aerosol canister bonded with a bag. The material liquid is filled in the pouch, and the propellant is filled between the pouch and the inner wall of the jar. When the valve is opened, the propellant squeezes the bag to squeeze the material out, and can form atomization, emulsion, gel and other states.
1. Binary packaging valve: Binary packaging valve can be male valve or female valve.
2. Binary valve bag: It is an aluminum composite bag approved by the Food and Drug Administration (it can be three or four layers according to different requirements of the product). According to different products, it can be applied to aerosols of various sizes.
3. Propellant: Because the propellant of the binary package is separated from the product, environmentally friendly propellants, such as compressed air, nitrogen, etc., can be used instead of combustible propellants.
4. According to different products, nozzles can be selected.
5. Binary packaging aerosol cans: both aluminum cans and tinplate cans can be used (aluminum cans are more recommended here). Jars of various shapes can be used.
6. Outer cover: various aerosol standard cover types can be used.
Binary aerosol filling process
The filling order of binary packaging is different from our ordinary one-way aerosol. The filling order of our general aerosol is the filling first, then the gas, while the binary packaging is just the opposite, the gas first, then the gas The specific steps are as follows:
Binary aerosol filling process
The pressure design of the binary packaging, the stability of the air tightness, the degree of opening of the bag during filling, and the corrosiveness of individual materials to aluminum materials are the keys to the stability of the finished binary packaging.
Binary packaging filling equipment
Due to the difference in filling sequence and structure, the dual packaging filling equipment is different in structure from the one yuan aerosol filling machine. The design concept is also different. Take the automatic binary packaging and filling equipment as an example. According to the different filling process, the binary packaging aerosol filling machine consists of a bottle unscrambler worktable, a binary packaging sealing inflator, a binary packaging liquid filling machine, It is composed of weighing machine, water bath leak detector, nozzle buckle machine, outer cover machine, online coding, conveyor belt, and PLC control program. It has the advantages of fast speed, convenient operation, accurate measurement, good sealing air tightness, and adjustable inflation pressure.
