Dairy Packaging Materials Selection Tips

Dairy products are rich in nutrients and are easily digested and absorbed by the body. It is an ideal food. With the improvement of people’s living standards and the deepening of their understanding of dairy products, especially in recent years, with the development of science and technology, the types of dairy products have gradually increased, the shelf life is longer, and they are more convenient to carry or drink, and are deeply loved by the public. .

But to choose the appropriate barrier properties of packaging materials, resulting in shortened milk powder shelf life. This requires suppliers to use aluminum foil and WMPET when producing milk powder. Attention should be paid to the selection of aluminum foil alloy grades. Because the aluminum foil alloy grades are different, it is related to whether the aluminum foil is broken after forming the bag, and the number of pinholes in the aluminum foil must be controlled. High quality aluminum foil must be used. When WMPET is to consider the strength and barrier properties of aluminum plating, it must pay attention to the scratching problem in the compounding process. A little scratch can damage the performance of the material.

Thirdly, the quality of the inner layer of ingredients in the formula of the inner layer of milk powder is also the key to the quality of milk powder. In addition to considering the heat sealing performance and mechanical strength, the inner layer material must also control the precipitation of the inner layer of the film additive to the pollution of the quality of the milk powder and cause the excessive static electricity to cause the powdered milk to adsorb on the inner layer of the film, resulting in failure to pour out.

China's production and manufacturing processes for foods and the management of endangering food safety will become more and more stringent. This requires dairy product manufacturers to further improve food safety awareness and purchase packing materials from packaging companies that have high integrity and good quality control measures.
