Talking about some knowledge of facial mask packaging bags

- Oct 02, 2020-

It is self-evident how important the mask packaging bag is to the mask. Compared with the fancy decoration on the surface, the storage and protection functions of the packaging bag are actually more important. But in fact, many people have ignored this point. To a large extent, this is because they do not understand the packaging itself.

First, let's learn about the relevant knowledge of aluminum foil bags. Aluminum foil bags are divided into aluminum-plated bags and pure aluminum bags. The aluminum-plated bag is to coat high-purity metal aluminum evenly on the plastic film under the high-temperature vacuum state. The pure aluminum bag is made of pure metal aluminum, which is combined with plastic to improve the plastic's barrier properties, sealing properties, fragrance retention, and shielding properties.

Aluminum foil bags and aluminum-plated bags can be distinguished in the following ways:

1. Watch:

Because the brightness of aluminum foil is not as bright as that of aluminum plating, the reflectivity of aluminum foil is not as good as that of aluminum-plated film. Aluminum-plated bags can illuminate the shadows of people, except for the matte film. The appearance of aluminized matting film is very similar to that of aluminum foil. You can block the mouth of the bag and look inside the bag through strong light. The inside of the aluminum foil bag does not transmit light.

2. Feel:

The aluminum foil bag feels thick and firm, harder and heavier. The aluminum foil bag feels lighter and softer than the aluminum foil bag.

3. Folding:

The aluminum foil bag is easy to fold to produce dead fold marks, and the aluminum-plated bag will not fold into dead fold marks, and it will rebound quickly.

4. Twisting:

After the aluminum foil bag is twisted, the coalescence is not easy to rebound, and the aluminum layer will break. After the aluminum-plated bag is twisted, the kinks will bounce away quickly, and the aluminum layer will not have obvious cracks.

5. Burning:

The fire point of aluminum foil is not easy to burn, the aluminum layer will be rolled back, and the aluminum foil packaging will leave gray aluminum slag after burning. When the aluminized film is fired, different plastic films can be burnt, and there is no residue of aluminum slag.

Mask packaging driven by function

Initially, the use of aluminum foil bags in facial mask packaging was mainly driven by functional requirements. The back of the mask usually has the words "Avoid direct sunlight, place it at room temperature and in a ventilated and dry place", which also reflects that in order to maintain the activity and effect of the mask, the mask packaging must achieve the following basic functions, 1. shading; 2 . Barrier property; 3 moisture resistance; 4 cooling property.

In general, aluminum foil bags can basically meet the above requirements. However, in a specific aspect, pure aluminum bags have greater advantages than aluminum-plated bags. For example, pure aluminum bags have complete light-shielding properties, while aluminum-plated bags have only certain light-shielding properties; in terms of barrier properties and cooling properties, pure aluminum bags Aluminum bags also have obvious advantages. In addition, aluminum foil bags also have multiple characteristics:

1 Strong air barrier performance, anti-oxidation, waterproof and moisture-proof.

2 Strong mechanical properties, high blast resistance, strong puncture resistance and tear resistance.

3 High temperature resistance (121℃), low temperature resistance (-50℃), oil resistance and good fragrance retention performance.

4 Non-toxic and tasteless, in line with food and drug packaging hygiene standards.

5 Good heat sealing performance, flexibility, and high barrier performance.

Not surprisingly, structural changes from aluminum-plated bags to pure aluminum bags have recently begun to appear on the market. The fierce competition in the mask market has spread to the packaging industry.

Structural transformation driven by high-end

Nowadays, high-end facial masks have become a trend. The four-layer product structure of PET+white kraft paper+AL+PE, in addition to excellent performance reflection, is the most intuitive reflection of texture. Relative to aluminum plating, pure aluminum + white kraft paper has a good metallic texture, silver-white, with anti-gloss properties; aluminum is soft.

Shanghai Yifu Packaging Co., Ltd. can customize packaging products of different composite materials and thicknesses according to customer requirements, in line with the pursuit of heavy texture for high-end products, and make high-end facial masks unique in packaging.

From the initial basic functional requirements of the mask bag to the high-end requirements of performance and texture synchronization, it is the transformation from aluminized bag to pure aluminum + paper bag, which is a structural transformation requirement of the mask packaging industry in the new era.
