What are the tips for choosing packaging materials for acrylic cream bottles and cosmetic containers

Cosmetics generally rely on packaging to achieve good sales. Plastics and glass are the main cosmetic container packaging materials in the current market. As for who will lead the trend in the future cosmetic packaging market, there are divergent opinions. With the continuous development of packaging materials, there are more and more packaging forms of modern cosmetics. Therefore, in order to better advertise products, it is more and more important to choose packaging materials suitable for various types of cosmetics.

General cosmetics are mostly in the form of liquids, creams or creams, and do not have a distinctive appearance. It must pass the exquisite and unique packaging design to show its own characteristics. Therefore, cosmetics generally rely on packaging to achieve good sales. Plastic and glass are currently the main cosmetic packaging and container materials, and most of them are plastic.

Although there are many types of cosmetics with different functions, in terms of their external shape and suitability for packaging, there are mainly the following categories: solid cosmetics, solid granular (powder) cosmetics, liquid and emulsion cosmetics, cream cosmetics Wait. According to different forms, the packaging forms are different.

Cosmetics need to be used for a long time, so they must include the ability to isolate light, moisture, temperature, etc. For foundations, the requirements for isolating moisture are higher. If the moisture is too much, the powder will become viscous and not suitable for use. Some cosmetics will change color in places with strong light. In this case, the ability of light isolation needs to be strengthened. Therefore, transparent cosmetic packaging is not suitable, and it is necessary to add packaging materials that can block light. Material to achieve the purpose of isolating light.

Our YAKIN packaging is one of China’s leading manufacturers and suppliers of plastic bottles, cosmetic bottles, cosmetic scrapers, and acrylic bottles. Cosmetic containers and packaging have a certain degree of sealing performance. After various environmental changes, they can There will be no leakage and deterioration during long-term use. Like temperature changes, there will be a strong sense of vibration during transportation, or impact when it is lost. In this case, it is necessary to use some materials with relatively high hardness to prevent the cosmetic packaging from deforming, thereby ensuring the performance of the seal.

The following is a brief description of how our YAKIN packaging improves the gas barrier performance of PET bottles of cosmetic packaging bottles from the following three main aspects:

PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields. From mold processing to machinery and equipment, they are very picky, easy to get started, but difficult to do. Next, we, China YAKIN packaging, will improve the gas barrier properties of PET bottles for cosmetic packaging bottles from the following three main aspects:

1. The strength and elasticity of PET are significantly higher than other raw materials, and it is suitable as a cosmetic plastic container with thin wall, light weight and high strength. PET bottles have been used in my country for many years and are developing rapidly. In recent years, it has become the country's main liquid and solid packaging container. In the application of pharmaceutical packaging, the weight of a PET bottle is only about 1/10 of that of a glass bottle when the filling volume is the same; for a packaging bottle of the same diameter, the capacity of a PET bottle is 1.5 times that of a glass bottle. PET raw materials can also be used to make transparent or opaque brown bottles, with various colors and exquisite appearance.

2. Due to the light weight, good storage performance, and the technical trend of emphasizing the functions of heat resistance and pressure resistance, the PET bottles of cosmetic packaging bottles have become the mainstream of cosmetic packaging today. Many beverages that require high temperature sterilization to be filled, such as flavored water, juice, dairy products, sports drinks, etc., are also packaged in PET bottles one after another. PET bottles have become the main packaging materials for cosmetic containers. Due to its low environmental pollution and energy consumption, PET bottles are gradually replacing traditional packaging materials in today's rising environmental awareness. With its heat-resistant and pressure-resistant functions, it has replaced various PVC bottles, aluminum cans, iron cans, glass bottles, etc., and has become a packaging material with growth potential.

3. There are four main ways to improve the gas barrier performance of PET bottles: processing by multi-layer co-extrusion technology to make it have a multi-layer composite structure; surface coating treatment; adding some gas trapping agents; and other materials with barrier properties Blended. Among them, the multi-layer co-extrusion technology is a method that has been successfully used, but the improvement of barrier performance is small, and it is difficult to recycle, and the cost is high. Surface coating is an emerging technology used to improve the gas barrier performance of PET bottles. A very thin gas barrier film can be obtained, which can effectively prevent gas molecules from passing through the PET bottle wall and at the same time solve the problem of recycling.

Some coating materials currently used have been tested in practice. Among them, diamond carbon film (DLC) and silicon oxide materials are very popular materials in the industry. Silicon oxide coating is used to improve the gas barrier properties of PET film earlier than diamond carbon film. In the early 1980s, silicon oxide coatings began to be obtained through physical vapor deposition and chemical vapor deposition. However, the silicon oxide film is brittle and requires relatively complicated processing in order to obtain long-lasting mechanical strength on the PET surface. In recent years, some products with diamond carbon film (amorphous hydrocarbon) coated on the surface of PET have appeared on the market, and the gas barrier properties of PET bottles have been greatly improved.
