Facial mask shaped packaging bag

Material: aluminum foil bag is the best choice

Nowadays, many female companions pay special attention to beauty and skin care. Women who are busy in daily life and work often use facial mask for skin care, which can provide sufficient nutrients for facial skin and make skin more healthy and energetic. With the increasing demand for facial mask, many manufacturers are increasing the production of facial mask. In order to further make the storage time of facial mask longer and facilitate the transportation and sale of goods, these manufacturers pay special attention to the choice of facial mask packaging materials. So what kind of material is better for facial mask bags.

Careful people will find that many facial mask packages will use aluminum foil packaging materials. Now many manufacturers will also customize aluminum foil packaging bags to package and sell facial mask. The stability of aluminum foil material is relatively good, and many substances are usually added to facial mask. If the stability of packaging materials is not high, they will react with these substances over time, which will lead to the deterioration of facial mask. Therefore, the selected packaging materials must have high stability, and aluminum foil bags are the best choice. Due to the higher stability of aluminum foil, the packaging bag made of this material can avoid the chemical reaction between the facial mask and the material.

Nowadays, many facial mask are transported by long-distance transportation before they can be delivered to the place of sale. In the long-term transportation process, many changes have taken place in the external temperature and light notes. In order to strengthen the storage time of facial mask, it is necessary to choose aluminum foil bags to pack facial mask. Since the packaging bag made of aluminum foil will not be affected by the surrounding temperature and humidity, which can ensure that the facial mask is safer in the process of transportation and will not deteriorate due to the change of the external environment, the use of aluminum foil packaging bag for facial mask packaging has gradually been recognized by users and aluminum foil bag manufacturers.

Most of the materials of facial mask packaging bags are aluminum foil or aluminum plating. The physical characteristics and requirements of facial mask bags are: in addition to excellent function reflection, the most intuitive thing on aluminum foil packaging bags is the performance of texture and the guarantee of the shelf life of facial mask. 12-36 months is the shelf life requirement of a few facial mask. The facial mask packaging bag has the ability of sealing and high barrier to meet the demand of such a long shelf life.

The material structure and requirements of facial mask packaging bags depend on the consumption characteristics of facial mask and its shelf life requirements. At present, the secondary structures of a few facial mask packaging bags are pet/vmpet/pe, pet/al/pet/pe, pet/al/pe, bopp/vmpet/pe, mat-opp/al/pe, bopp/al/pe, mat-opp/vmpet/pe, etc.

The above is the analysis of some achievements we encountered in the consumption of facial mask packaging bags. If it is to indicate the information, we will take pet/al/pe general materials as an example.

1、 Flatness of bag end face

1. Knife cut threading

Generally speaking, aluminum foil bags are relatively less silk, presenting this scene is nothing more than that the cutting knife is not leveled, or there may be a gap in the cutting knife.

2. Aluminum particles on end face

If the cutting knife is uneven and the blade is not flat, the end face of the incision will show aluminum foil one by one, and the scene will be clearer when it is erected in a whole bag. At this time, take the cutting knife to polish and level it or replace it with a new one.

3. Shaped bag incision

In order to express its characteristics, more and more packaging bags are shaped, and facial mask packaging bags are no exception. In many cases, profiled die-cutting knives are more likely to show aluminum particles (uneven cutting). We should deal with this phenomenon: first, improve the material of the die-cutting knife to make the blade of the knife more tough and sharp; Second, the template base of the cutter should be flat and the blade should be flat.

2、 Smoothness of bag surface

1. There is indentation on the bag surface

This kind of scene is usually caused by foreign matters on the guide roller or the transmission roller. Timely clearing of guide rollers and transmission parts, especially the parts passed by the composite film, is the key to avoiding this scene.

2. There are strip marks on the bag surface

A few of such scenes are due to the fact that the position of the tripod is not flat, or the guide roller is uneven.

3. Scratch on the bag surface

This kind of scene is mainly caused by slipping in the transmission part, or there may be sharp objects against it. It is necessary to find the end point of the scratch and stop the ineffective disposal before the scratch can be eliminated.

3、 Finished bag edge banding

1. Edge banding wrinkle

The PE layer in the facial mask bag of pet/al/pe is generally the common PE data of facial mask, which is characterized by high temperature heat sealing. In the process of heat sealing, if the temperature is too high, there will be wrinkles, and if the temperature is too high, there will be virtual sealing. Therefore, in the process of consumption, the temperature of each heat sealing knife is different at different speed points. It is necessary to record and compare the data to obtain the best comparison table of speed and temperature. In addition, the appropriate temperature range is marked on the PE raw material, so that the captain can better control the edge banding temperature. Part of the heat sealing knife, if uneven, will show edge wrinkles. In the process of heat sealing, not only the hot knife will affect the edge sealing, but also the cooling knife is very important. If the temperature of the cooling knife is not low enough, there will also be edge banding wrinkles. Compared with PET fabric, mat-opp is easier to show sealing wrinkles.

2. Edge sealing and virtual sealing scene

There are two major elements in presenting the virtual sealing Imagination: first, there are sundries between PE and PE during heat sealing. To deal with this problem, on the one hand, it is necessary to ensure that the bag making material and the bag making machine are clean, on the other hand, the width of the loss edge of bag making should not be too large. Second, the heat is uneven during heat sealing. This time, if the heat sealing knife is uneven, maybe the screw is not locked, and the thickness of the material can also lead to this phenomenon. Therefore, the thickness uniformity of materials is very important.

3. Edge banding bubble scene

Generally speaking, the edge sealing bubbles of aluminum foil bags are caused by the high temperature transition of the heat sealing knife. But on the other hand, it can be caused by the uneven pressure of the heat sealing knife or too much.

4. Uneven edge banding

The aluminum foil is scratched and walks with the composite roll film, which is easy to stay on the edge of the heat sealing knife, forming a hard object and causing depression; In addition, PE particles adhere to the cooling knife, causing edge banding pits.
