Introduction of cosmetic mask packaging bag

The rise of cosmetic mask packaging bags

    The rise of the attention economy has brought the whole people into the “face-seeing era”. There are many types of skin care products, which are highly sought after by women. Among them, facial mask products are easy to use and cost-effective, and gradually become the most widely used product in cosmetics, and even many men use facial masks. People use the mask to cover the face for a short time to temporarily isolate the outside air and pollution, increase the temperature of the skin, expand the pores of the skin, promote sweat gland secretion and metabolism, increase the oxygen content of the skin, and help the skin eliminate epidermal cell metabolism The products and accumulated oils and fats, the moisture and nutrients in the mask penetrate into the stratum corneum of the epidermis, the skin becomes soft, and the skin is naturally bright and elastic. Therefore, facial mask packaging has become an important category in flexible packaging, and more and more companies specialize in making facial mask bags and films. The mask is composed of membrane materials and essences. The essences mainly include water, moisturizers, preservatives, viscosity modifiers, efficacy or plant extracts, soothing ingredients, stabilizers, flavors and pigments, etc. It is rich in amino acids, collagen, vitamins and biologically extracted active substances.

Material requirements for the packaging bag of the mask


    Therefore, the packaging material of the mask must have:

a. Excellent oxygen and moisture resistance;

b. Good fragrance retention;

c. Excellent leakage resistance;

d. Excellent acid and alkali resistance.

     Therefore, aluminum foil bags and aluminum-plastic bags with good stability, barrier properties and puncture resistance have become the best choice for facial mask packaging. Common facial mask packaging bag structure: PET/AL/PE, PET/AL/PET/PE, PET/VMPET/PE, BOPP/VMPET/PE, BOPP/AL/PE, MAT-OPP/VMPET/PE, MAT-OPP/ AL/PE.


A. Aluminum foil selection on the mask packaging bag
    From the perspective of the main material structure, aluminized film and pure aluminum film are basically used in the packaging structure. Compared with aluminum plating, pure aluminum has a good metallic texture, silvery white, and has anti-gloss properties; aluminum has soft characteristics, and products with different composite materials and thicknesses can be customized according to requirements, which meets the pursuit of high-end products for heavy textures and makes high-end masks Get a more intuitive manifestation from the packaging.
    Because of this, the basic functional requirements of facial mask packaging bags from the very beginning to the high-end requirements of performance and texture rising simultaneously have contributed to the transformation of facial mask bags from aluminum-plated bags to pure aluminum bags.
     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 neglect this point.
    Analyzing from the raw material itself, general facial mask packaging bags are mainly divided into two types: aluminized bags and pure aluminum bags. The aluminum-plated bag is to coat high-purity metal aluminum evenly on the plastic film under high-temperature vacuum. The pure aluminum bag is formed by the extension of pure metal aluminum sheet, and is compounded with the plastic film, which can improve the plastic’s barrier properties, sealing properties, fragrance retention, shielding and other functions. In other words, pure aluminum facial mask bags are more suitable for the market requirements of mask packaging bags.
B. Selection of PE on the mask packaging bag
    The heat-sealing layer of the mask packaging bag basically chooses PE. Both the surface layer and the core layer are produced by more advanced large-scale thin film production lines, with little difference in quality and relatively stable quality. However, the production of PE film is very different, and it is uneven. One is the process equipment and the other is the choice of raw materials that determines the quality and stability of the PE film. Although there are many manufacturers, it is still difficult for soft package manufacturers to choose suitable PE products. For example, the sealing edge of the facial mask packaging bag is wrinkled, emptied, bubbled, and uneven; or the surface of the bag is not flat; it is not easy to open when packaging, it is not easy to tear after packaging, and even leaks and other quality problems frequently occur. Regardless of the factors of printing and compounding process, it can be said that the quality stability of PE film is the decisive factor of product quality. Numerous quality cases have concluded that a good PE film must have the following elements:
1. Less small molecule precipitates, less slip agent and anti-blocking agent. Too much will cause weak composite and poor opening.
2. The heat shrinkage rate of the film should be low, too high will cause the sealing edge to wrinkle and the bag surface is not flat.
3. The unsealing temperature should be low, the heat-sealing strength should be high and there should be a certain degree of stain resistance, so that the bag will not appear false sealing and leakage.
4. It must have straight-line and easy-to-tear performance, and the bag’s tearing mouth is flat and easy to tear so that customers have a better experience.
    In response to the above requirements, Shanghai Duxia Industry and Trade has developed a special polyethylene cast film for the segmented market of facial mask bags through equipment transformation, raw material screening and process formula optimization.
1. The aluminum foil composite bag does not require transparency and haze, so we use physical embossing to make the surface of the film have micro bumps, so that there is an air gap between the films. The film can be opened well with little or no slip agent opening agent. At the same time, the special texture structure and the micro-stretch orientation of the film enhance the straight-line tearability. At the same time, the influence of precipitates on the composite strength is reduced.
2. The formula design of high-carbon PE raw material and metallocene PE ensures the anti-fouling and sealing performance of the bag.
3. The film goes through several cold and hot rollers alternately to eliminate the stress, which greatly improves the dimensional stability. Coupled with the inherent advantages of low thickness deviation and high flatness of the casting process, the quality of the special PE film is unattainable by the traditional blown film process.
Factory production requirements for facial mask packaging bags:
     All GMP standard factory buildings require a laminar flow environment. The laminar flow is divided into one million, one hundred thousand and ten thousand. This level parameter refers to how many particles (ash layer, bacterial spores, etc.) are in 1 cubic meter of space in this environment ), the smaller the number of stages means the cleaner the environment. For example, 10,000-level laminar flow means that there are only 10,000 particles in 1 cubic meter of air in this environment. Generally, the processing of facial masks uses million-level laminar flow or 100,000 level. Laminar flow.
The development trend of cosmetic packaging
     The packaging of cosmetics needs to be protective, functional and decorative. The trinity is the future development direction of cosmetics packaging.

    ◆ Fresh-keeping cosmetics will occupy a considerable market. In order to meet the needs of customers, manufacturers produce products without preservatives. Manufacturers fill them in extremely small containers, and customers can use them up at once. For example, many brands of essences use this packaging method. The price of this kind of cosmetics is too high to become a mainstream product in the market, but it is a sign of the future fashionable and luxurious lifestyle, so there will be a stable consumer group.

     ◆ Development and design of green packaging materials. Many cosmetic manufacturers have begun to pay attention to environmental protection issues, and they have also added environmental protection considerations to the selection of cosmetic packaging materials, considering whether these materials can be recycled, which is in line with the increasingly important environmental awareness.

    ◆ Multi-layer plastic composite technology. It can make multiple layers of different types of plastics compound together and form them at one time. You can choose any imaginable color and design all kinds of containers. With the multi-layer molding technology, on the one hand, plastic packaging can completely isolate light and air and avoid oxidation of skin care products. On the other hand, by mixing different kinds of substances, it can obtain wonderful visual effects and unique feel in appearance, which improves Flexibility of the hose.

    ◆ Vacuum packaging is quietly emerging. Vacuum packaging can protect skin care products that contain fat, rosin oil, and vitamins. It has the advantages of strong protection and high elasticity recovery. Another important development direction of vacuum packaging is to highlight functionality, which is very important for less complicated containers.
