Importance of packaging of infant milk powder

In the process of processing, storage and handling, infant formula milk powder will have some unfavorable effects on nutrients in varying degrees. Packaging separates infant formula from the surrounding environment, thereby eliminating the effects of environmental factors (oxygen, humidity, light, temperature and microorganisms) on the milk powder, and avoiding physical and chemical changes in the nutrient contents. To ensure that the milk powder is in product circulation links with stable quality, extend shelf-life and storage-life of milk powder.

Stable and beautiful packaging can increase the value of infant milk powder to consumers with a sense of hygiene, nutrition, taste and sense of security. Thereby enhancing the value of the milk powder, effectively promote the sale of milk powder.

Nitrogen, accounting for 78% of the volume of air, exists in air as an elemental substance and is inexhaustible and inexhaustible. It is a colorless, non-toxic and tasteless inert gas.

Filling some nitrogen in the bags or cans that filled milk powder, segregated the milk powder direct contact from the oxygen in air, to prevent the oxygen and infant milk powder direct contact caused by with oxidation, fading, corruption and a variety of mold, bacteria, thus ensuring the freshness of infant milk powder, extending the storage period of infant milk powder.

Moreover, since the special physical properties of nitrogen is different from the preservative treatment of chemical, no residue remains. Because the two atoms of nitrogen are combined by three bonds, the structure of the nitrogen molecule is very stable, that is, the nitrogen molecule is not required electrons and not loosed electrons. Only under certain circumstances can the covalent bond be broken. Therefore, nitrogen is very stable under room temperature, it can be said that it is not active, so infant milk powder in nitrogen gas is not perishable, it will have a longer shelf-life and storage-life.

Milk powder is a kind of for young and old rich food, milk powder packing also increased as the dairy industry in the market competition by the cost factors, low-cost milk powder bags began to more and more widely applied.  

The quality requirements of milk powder for packaging and materials are mainly based on functional requirements, including safety factors such as oxygen barrier, moisture resistance, light protection, sealing, odor (solvent residue), and its printing and machinery properties, such as physical properties, heat sealing properties, surface slip, printing quality, etc.
