Prominent rise of milk powder flexible packaging or will become a new trend in the industry

At present, the market for milk powder packaging mainly consists of metal cans and plastic flexible bags. Metal cans have good tightness 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 to some products. The same quality of canned milk powder, the market price is generally more than 30% more expensive than bagged milk powder. Therefore, with the intensification of competition in the dairy industry, due to cost factors, metal cans are gradually replaced by lightweight plastic packaging.

In other milk powder packaging, the packaging cost of the aluminum-containing foil structure is relatively high, but the shelf life is longer, and generally can reach one and a half to two years. The cost of packaging aluminum-plated structure is relatively low, but the shelf life is relatively short, generally not more than a year and a half. For the BOPP structure, since the heat resistance of the BOPP material is not good, it is generally not suitable for use on automatic packaging machines, and is mainly used for making prefabricated bags for manual packaging.

Due to the safety of product quality, the national milk powder for infants and young children must be packaged with aluminum foil, and other products such as adult milk powder can be packaged with aluminum plating. At present, many milk powder factories have changed most of their milk powder packaging into aluminum-plated structures, leaving only infant milk powder packaging unchanged, and some multinational dairy companies, including Nestlé, have implemented this.

However, there are also researches in the industry that will adopt non-pollution organic polymer materials instead of metal aluminum foils to outsource the packaging. In addition, high-barrier aluminizing materials also have a large development market and will replace aluminum foils. Due to the high production cost of metal irrigation packaging, the gas tightness is low. And the materials used are non-renewable resources that pollute the atmosphere and rivers during production. Organic polymer materials are more environmentally friendly, packaging products are less hazardous, and production costs are lower.

Rolled milk packaging suddenly rises

As we all know, the packaging of milk powder from the 20 to 30 years ago to the box to the current tin packaging several times easy to install, in addition to catering to the people's shopping psychology, but also for practical considerations, keep milk sealed storage is to prevent milk powder moisture Or the most effective means of causing nutrient loss through pollution.

Bar packaging, that is, independent packaging, we are not unfamiliar, is widely used in condiments, solid beverages and other products, has been welcomed by the majority of consumers with its easy to carry, clean and sanitary features. Infant formula milk powder is packed in strips, which is lighter and easier to carry compared to large packages. It does not cause parents to carry young children to travel; it is also more tightly sealed. When used, there is no need to weigh cups, one at a time, and there are no more. The risk of secondary pollution.

The advantages of strip packaging are obvious, but for milk powder manufacturers, the use of strip packaging is not an overnight one. First of all, the increase in packaging costs, this is the barrier for most companies to use strip packaging; Second, the high-speed strip packaging makes existing single large packaging packaging production line facing the pressure of speed; Finally, the production date, batch number, shelf life, etc. The information in the packaging must be identified on the strip packaging to ensure the quality of the individual packaged product is monitored and traced.

Bar packaging infant formula milk powder will surely rise with its safety and convenience, change the infant milk formula industry sector, and lead the new trend of milk powder industry.
