In recent years, with the improvement of people's living standards and the world's leading food companies continuously entering the Chinese market, China's dairy industry has shown a vigorous development trend, in which the consumption of high-quality, highly nutritious milk powder is increasing. At present, the milk powder packaging on the market is mainly in the form of metal cans and milk powder packaging bags. Metal cans have good sealing and long shelf life, but their production and transportation costs are relatively high. Therefore, only a few large well-known dairy companies apply this type of packaging on some products. The market price of canned milk powder of the same quality is generally more than 30% more expensive than bagged milk powder. Corresponding to this, dry compound milk powder packaging bags, which have a tendency to replace iron cans, have gradually gained a higher and higher market share.
Among them, the cost of milk powder packaging bags with aluminum foil structure is relatively high, but the shelf life is longer, generally reaching one and a half to two years. The cost of milk powder packaging bags with aluminum structure is relatively low, but the shelf life is relatively short, generally not more than one and a half years. As for the BOPP structure, due to the poor heat resistance of the BOPP material itself, it is generally not suitable for use on automatic packaging machines. It is mainly used to make pre-made bags for manual packaging. When the milk powder needs to be transported for a long distance or the packaging material is easy to squeeze and rub during the storage and transportation process, if you choose this type of packaging, the performance of the material compounded with aluminum foil is crucial. The commonly used milk powder packaging bag composite design is PET / AL / CPP, PET / AL / PA / CPP, PET / NY / AL / NY / CPP, etc.
For packaging material manufacturers, they all know that milk powder packaging bags are mainly to improve the design and provide more convenience; improve the structure of composite materials to meet more stringent requirements. The future development trend is the development of multi-layer composite airtight plastics, functional plastics, and biodegradable plastics.
Strip packaging, which is independent packaging, is not new to us. It is widely used in condiments, solid beverages and other products. It has always been popular among consumers because of its convenient portability and cleanliness. Infant formula milk powder is packed in strips. Compared with large packaging, it is light and easy to carry, and it will not burden parents to take young children to travel. Its sealing is also stronger. When using, there is no need to weigh the measuring cup, one at a time, there is not much The risk of secondary pollution.
The advantages of strip packaging are obvious, but for milk powder manufacturers, it is not easy to use strip milk packaging bags. First, the increase in packaging costs, which is a roadblock for most companies to use strip packaging; second, the high-speed strip packaging makes the existing single large packaging packaging production line face pressure to speed up; finally, the production date, batch number, shelf life, etc. The information in the packaging must be marked on the strip packaging to ensure the monitoring and traceability of the quality of the individually packaged products.
In general, the strip-shaped infant formula milk powder will surely emerge with its safety and convenience, change the infant formula milk powder industry landscape, and lead the new trend of the milk powder industry.
