Development trend of mask bags
It is self-evident that mask bags are important to mask. Compared with the fancy decorative function of the surface, the storage and protection functions of the packaging bag are actually more important. However, in fact, many people ignore this point. To a large extent, it is because they do not understand the packaging bag itself.
First of all, let's learn something about aluminum foil bags. Aluminum foil bags are divided into aluminum bags and pure aluminum bags. Aluminum bag is a high-temperature vacuum state, the high-purity metal aluminum evenly coated on the plastic film. The pure aluminum bag is made of pure metal aluminum. When combined with plastic, it can improve the barrier, sealing, fragrance retention and shielding properties of the plastic.
1、 Distinguish between aluminum foil bag and aluminized bag
1. View: because the brightness of aluminum foil is not as bright as that of aluminum plating, the reflective property of aluminum foil is not as good as that of aluminum plated film. Aluminum coated bag can give out human shadow, except for those with aluminum coating on extinction film. The appearance of aluminum coating on the extinction film is similar to that of aluminum foil. You can block the opening of the bag and look inside the bag through the strong light. The inside of the aluminum foil bag is not transparent, and the transparent one is the aluminized bag.
2. Handle: the handle of aluminum foil bag is thick and straight, hard and heavy, and the handle of aluminum plated bag is lighter and softer than that of aluminum foil bag.
3. Folding: the aluminum foil bag is easy to fold out the dead fold mark. The aluminum plated bag will not fold into the dead fold dead mark, and it will rebound quickly.
4. Twisting: after twisting the aluminum foil bag, the coalescence is not easy to rebound, and the aluminum layer will break. After twisting the aluminum coated bag, the kink will pop up quickly, and the aluminum layer will not have obvious cracks.
5. Burning: the aluminum foil is not easy to burn with the fire point, and the aluminum layer will roll back. After burning, the aluminum foil packaging will leave gray aluminum slag. When the aluminized film is burned, there is no residual aluminum slag.
Two, function driven mask packaging
In the beginning, the use of aluminum foil bags on mask packaging was mainly driven by functional demand drivers. On the back of the mask, there is usually such a word "avoid direct sunlight, placed at room temperature and ventilated dry place", which is also reflected in order to maintain the activity and effect of the mask.
Three, mask packaging must meet the following basic functions:
1. Shading; 2. Barrier; 3. Moisture resistance; 4. Cooling
Generally speaking, the aluminum foil bag can basically meet the above requirements. But in a specific aspect, the pure aluminum bag has more advantages than the aluminized bag. For example, the pure aluminum bag has complete lightproof property, while the aluminized bag has only certain shading property; in terms of barrier and cooling performance, pure aluminum bag also has obvious advantages.
4、 Aluminum foil bags also have a variety of characteristics:
1. Strong air barrier, oxidation proof, waterproof and moisture-proof.
2. Strong mechanical properties, high explosion resistance, puncture resistance and tear resistance.
3. It has good resistance to high temperature (121 ℃), low temperature (- 50 ℃), oil resistance and aroma retention.
4. It is non-toxic and tasteless, and meets the hygienic standards of food and drug packaging.
5. Good heat sealing performance, flexibility and high barrier performance.
No wonder, the recent market began to appear in the aluminum bag to pure aluminum bag structure change. The white hot competition in the mask market has spread to the packaging industry.
5、 Structural transformation driven by high end
Today, high-end mask has become a trend, in addition to outstanding performance reflection on the aluminum foil bag, the most intuitive is the embodiment of texture. Relative aluminum plating, pure aluminum has good metal quality, silver white, reflective properties, aluminum metal characteristics are soft, world packaging can be customized according to the requirements of different composite material and thickness of products, in line with high-end products for heavy weight pursuit, so that high-end mask from the packaging is reflected.
From the beginning of the basic functional requirements to the high-end requirements of performance and texture, the mask bag is the transformation from aluminized bags to pure aluminum bags. It belongs to the structural transformation requirements of the packaging industry in the new era.
