The functional characteristics of cosmetics packaging

Flexible packaging of cosmetics function mainly reflects in the following three aspects. （ 1) To prevent the volatilization of built-in objects. Non-woven products containing leaching liquid of wet cloth more contain moisture, such as ethanol, barrier property to film requirement, non-woven leaching liquid content too much, function when using drip; Too little, as a wet cloth, lack of satisfaction. Pillow packaging can be selected to K - wet cloth OPP/K - PET for blocking layer Modified PET/PE. As another example, odour bag, for example, to use period, fragrance waft, a cloth or paper, and in the process of circulation, in order to prevent these volatile fragrance, it is necessary to use the barrier property of thin film coating. And sales, can see on the smell of the built-in bags, transparent film, can use high barrier property of EVOH film at this time. （ 2) Within resistant property. With non-woven fabric containing leaching lotion, latex products, such products use of alcohol or water transparent packaging materials of high barrier property, because it can also cause the ageing of the built-in objects, and there is a need for shading; And give priority to use aluminum foil blocking layer shading performance of composite film packaging, such as the use of PET/AL/CPP packaging toner, emulsion of non-woven fabrics. On the design of packaging film, should make full attention and guarantee the lining of the built-in objects in direct contact, usually in the form of PE or CPP, because it will happen or take off a layer, therefore need to use the heat sealing good, good corrosion resistance of modified PE, such as modified PET/AL/PE. （ 3) Moisture resistance. Such as powder bath agent or washing fabrics, when used in bath or more than the pool that wash a face moisture. Products when packing, pay attention to prevent moisture absorption, built-in metamorphism, want to have better moisture resistance than usual, such products can use aluminum foil composite film, such as PET/AL/CPP for packaging.
