Why is the mask packed in an aluminum foil bag?


Usually the mask will be packed in an aluminum foil bag, because its surface is generally opaque. And it is multi-layered, which makes the aluminum foil bag have good shading performance. If there is a photosensitive substance in the mask, it will be well protected.


At the same time, the aluminum foil bag also has strong heat preservation. Due to its good oil resistance and softness. Various physical or chemical reactions between mask raw materials and packaging can be avoided to a large extent. It can effectively guarantee the safety of the mask during transportation and storage.


Since the mask package basically contains aluminum plating or pure aluminum, the presence of composite aluminum plating or pure aluminum is not conducive to the volatilization of solvents, because the barrier properties of these two materials are stronger than other general materials. Therefore, it is unfavorable for the volatilization of solvents. Although it is clearly stipulated in GB/T10004-2008 "Dry Extrusion Compounding of Plastic Composite Films and Bags for Packaging". However, this standard does not apply to plastic films and packaging bags made of paper or aluminum foil composite plastic materials.

Mask bags generally use aluminum foil because it has a good light-proof function. It can prolong the shelf life of the mask. But the aluminum foil of the mask pack can be divided into plated aluminum and pure aluminum. Customers with high requirements will choose the commonly used pure aluminum. The mask is in direct contact with human skin. The mask originally contains medicinal ingredients, so its packaging requires good airtightness and high barrier properties. The mask bags on the market are generally marked with a shelf life, usually 12 months, and some even 36 months, so the mask bags are generally made of pure aluminum or covered with aluminum. The mask is composed of more than two layers and more than two layers of materials.


From the analysis of raw materials, general mask bags are mainly divided into aluminum-plated bags and pure aluminum bags. The aluminized bag is made by uniformly coating high-purity gold and aluminum on the plastic film under high-temperature vacuum. For pure aluminum bags. The combination of aluminum foil and plastic film, a downstream product of the aluminum industry chain, can improve the barrier properties, sealing properties, fragrance retention and shielding properties of plastics. In other words, pure aluminum mask bags are more suitable for the current market requirements for mask bags.


Made of composite materials. In fact, it can be seen that the composite structure is basically made of aluminum-plated or pure aluminum material. The aluminum-plated metal has a good texture, silvery white, reflective light, and has a strong decorative effect. Pure aluminum has the property of being softer than aluminum. Stronger texture and better performance. So more and more mask bags are made of pure aluminum.


Why do masks always choose aluminum foil bag packaging? Because its surface is generally opaque and made of multiple layers, the aluminum foil bag has good shading performance. If there is photosensitive material in the mask, it will be well protected. At the same time, aluminum foil packaging also has strong insulation. Due to its good oil resistance and softness, various physical or chemical reactions between the raw material of the mask and the packaging can be avoided to a large extent, and the safety of the mask during transportation and storage can be effectively guaranteed.
