How to choose cosmetic packaging materials reasonably?

Cosmetics generally rely on packaging to achieve good sales. Plastic and glass are the most important cosmetic packaging materials on the current market. With the continuous development of packaging materials, there are more and more packaging forms of modern cosmetics. Therefore, in order to better promote products, it is increasingly important to choose packaging materials suitable for various types of cosmetics.

Cosmetic packaging materials can generally be divided into two parts: main packaging materials and auxiliary packaging materials.

The main packaging materials usually refer to glass bottles, plastic bottles, plastic hoses, etc. that are in direct contact with the product.

Auxiliary packaging materials usually refer to packaging materials that are not in direct contact with the product, such as paper labels, plastic labels, paper color boxes, plastic color boxes, corrugated boxes, etc.

Whether it is the main packaging material or the auxiliary packaging material, it must meet the three basic requirements of packaging in the circulation process, namely protecting products, facilitating storage and transportation, and promoting sales. Moreover, with the continuous development of modern society, cosmetic packaging, on the premise of meeting its basic functions, must also bear responsibilities such as improving product taste, representing brand culture, and enhancing product value. In particular, high-end cosmetics have particularly prominent requirements in this regard. . In addition, during the entire process from filling to consumer use of cosmetics, the main packaging materials are in direct contact with the cosmetics, so the quality of the packaging will directly affect consumers' judgment of product quality.

So, what aspects should be considered when choosing cosmetic packaging materials?

Selection of main packaging materials

When selecting the main packaging materials for cosmetics, attention should be paid to meeting the following performance requirements.

1. Certain mechanical properties

Packaging materials should be able to effectively protect products, so they must have a certain degree of strength, toughness and elasticity to adapt to the influence of static and dynamic factors such as pressure, impact, vibration and so on. For cosmetic packaging materials, specific issues need to be analyzed in detail. For example, the overall impact resistance of mirror box products must reach a certain standard to prevent consumers from accidentally dropping them during use, resulting in cracking or even damage. In particular, the buckle of the mirror box is more susceptible to damage. Broken by impact. For lipstick tubes with gold-plated surfaces, the surface of the lipstick tube requires a certain hardness. Appropriately increasing the intensity of light during the production process can improve the surface hardness of the lipstick tube.

2. Barrier performance

According to the different packaging requirements of cosmetics, packaging materials should have certain barrier properties against moisture, light, aromatic gases, etc. For example, products such as scrubs and foundations have relatively high requirements for the water barrier properties of packaging materials. This is mainly because these products have low water content and have strict requirements on water loss. Therefore, five-layer tubes or composite tubes with good barrier properties should be used. Packaging materials, single-layer tubes are not suitable for packaging. There are also some cosmetic ingredients that are very sensitive to light. They will produce obvious discoloration when exposed to incandescent light sources or ultraviolet light, which greatly affects the sense of the product. Therefore, transparent packaging cannot be used and color masterbatch must be added to the packaging material to achieve the desired effect. The purpose of blocking light.

3. Compatibility

Packaging materials should not cause unacceptable changes in cosmetics or packaging after storage in high temperature and high humidity environments. Cosmetics are always in contact with the packaging, and will experience changes in temperature and humidity in the environment during transportation and use. As a result, the volatile components contained in the cosmetics themselves may react chemically with the packaging materials at high temperatures, causing the appearance of the packaging materials to change. , physical properties and chemical properties change. For example, after PET bottles come into contact with cosmetics, they are prone to bending and deformation at a temperature of 50 degrees; when a hose with poor corona comes into contact with cosmetics, it will affect the sealing performance of the sealing part, causing product leakage; plastic hoses After the thread part comes into contact with cosmetics, it is easy to crack. If the material at the thread is a mixture of HDPE and LDPE, then increasing the ratio of LDPE and reducing the ratio of HDPE will help to improve the cracking phenomenon.

4.Sealing performance

Packaging materials should be able to ensure a certain sealing performance and prevent product leakage during various environmental changes. The environmental changes referred to here mainly include vibrations generated during transportation, impacts caused by falling, material deformation caused by changes in temperature and humidity, etc. For example, dust-proof plastic gaskets often used in bottles are in direct contact with the product. If softer materials are used, they are easily deformed, thus affecting the sealing performance. Therefore, it is best to use harder materials, such as PP, PET-G, etc., for the key structures of the seal.

5. Economic performance and cost requirements

While ensuring packaging quality, economic performance and cost requirements must also be considered. This requires comparative testing of the performance of different materials, and then selecting appropriate and economical packaging materials based on past experience. Of course, excessive packaging must also be avoided, as using appropriate packaging materials can save a lot of costs and achieve the safest protection of the product at a lower cost.

Selection of auxiliary packaging materials

When selecting auxiliary packaging materials for cosmetics, attention should be paid to meeting the following performance requirements.

1. Certain mechanical properties

Auxiliary packaging should be able to effectively protect finished product packaging or unassembled parts. Therefore, color boxes and corrugated boxes for packaging cosmetics must have certain mechanical properties such as strength, toughness and elasticity to adapt to the influence of static and dynamic factors such as impact and vibration during product logistics. In addition, there is another factor that cannot be ignored, and that is the placement of the products inside the package. As a corrugated carton for transportation packaging, there should not be too big a gap inside, so as to prevent the cosmetics from being greatly displaced during transportation and causing the appearance of the product. scratches, thereby affecting its sales.

2. Certain environmental tolerance

Decorations on labels and main packaging materials are generally bonded to the main packaging material with adhesives. The environmental tolerance here mainly refers to the adhesive's tolerance to temperature and humidity. Because the finished product package must go through the transportation process before it reaches the consumer, and the transportation environment is diverse, including high temperature and high humidity, low temperature and dryness, and may also experience strong sunlight, which has a negative impact on the adhesive. Adhesives have put forward higher environmental tolerance requirements, especially for imported and exported cosmetics. More attention must be paid to the reasonable selection of adhesives, and it is best to conduct corresponding testing before actual transportation.

3. Economic performance and cost requirements

Like the selection of main packaging materials, when selecting auxiliary packaging materials, while ensuring packaging quality, economic performance and cost requirements must also be considered. This also requires comparative testing of the performance of different materials, and then selecting based on past experience. Suitable and economical packaging materials.

The reasonable selection of cosmetic packaging materials is related to the safety performance of the overall product, which directly affects product quality and consumers' evaluation of the brand. Therefore, we must pay full attention to it and continuously accumulate experience. The selection of cosmetic packaging materials is a comprehensive evaluation process. Changes in product composition, type, transportation, storage environment and other factors will have an impact on the selection of packaging materials. Therefore, it must be combined with the actual situation in order to select the appropriate product. Packaging Materials.
