Permeability of the polymer package and storage life of the packed milk products

One of the principle tasks of a package is products preserving from negative factors of environment. Packaging materials that fulfill the function are often called barrier. Major part of milk products possesses ability to adsorb heavy metals, various organic compound and as a result they can become unsuitable for consumption. For milk products a negative factor is considered to be presence of oxygen in the package volume. Quality of the products can be deteriorated also after moisture penetration or removal. These factors acquire special meaning when we store high fat products, for example, oils as well as products that intensively adsorb moisture and have large specific area - milk powders and dry baby food mixtures.
