What is the performance of cosmetic plastic packaging?

Cosmetic plastic packaging has diverse properties. Common cosmetic packaging forms mainly include plastic bottles, hoses, glass bottles, and soft plastic packaging bags. The following is a detailed analysis of its performance:

一、Basic physical properties

1. Portability: Plastic packaging is relatively light and easy to store, transport and carry, which is an important advantage for cosmetics.

2. Plasticity: Plastic materials have good processing properties and can be made into packaging containers of various sizes, shapes and specifications to meet the packaging needs of different cosmetics.

3. Sealing: Plastic packaging usually has good sealing, which can effectively prevent air, moisture and impurities from entering the inside of the packaging and protect the quality of cosmetics.

二、chemical stability

1. Chemical resistance: Different types of plastics have different tolerances to cosmetic ingredients. For example, ABS (acrylonitrile-butadiene-styrene copolymer) has good chemical resistance and is suitable for most cosmetics, while PE (polyethylene) also has good resistance to most cosmetic ingredients, but may Reacts with certain volatile ingredients.

2. Stability: Stabilizers, antioxidants and other additives may be added to plastic packaging during the production process to improve its chemical stability. However, after long-term exposure to cosmetics, migration of small molecular substances into the packaging contents may still occur.

三、Optical properties

1. Transparency: Some plastic packaging such as PET (polyethylene terephthalate) has good transparency, which can clearly display the color and texture of cosmetics and enhance the appeal of the product.

2. Glossiness: Some high-end cosmetic plastic packaging also has high gloss, such as PCTG (polyethylene terephthalate-1,4-cyclohexanedimethanol) and other materials, which can give the packaging a high-end and elegant look. appearance.

四、Environmental performance

1. Recyclability: As environmental awareness increases, more and more cosmetic plastic packaging begins to use recyclable materials. For example, plastic materials such as PET have high recycling value and can effectively reduce environmental pollution.

2. Biodegradability: Some new plastic materials such as PLA (polylactic acid) have good biodegradability and can gradually decompose in the natural environment, reducing the negative impact on the environment.

五、Other properties

1. Printing performance: The surface of plastic packaging is easy to color and print, and can easily print various patterns, text, barcodes and other information to improve product recognition and aesthetics.

2. Protective properties: Some plastic packaging also has good protective properties, such as light blocking, oxygen blocking and other properties, which can further protect the quality and stability of cosmetics.

To sum up, cosmetic plastic packaging performs well in terms of portability, plasticity, sealing, chemical stability, optical properties, environmental performance and other properties. At present, there are some methods for reusing plastic bottles, such as making them into various exquisite handicrafts. As long as cosmetic plastic packaging manufacturers dig into it, there can still be solutions. 

In modern society, the continuous emergence of new packaging materials and technologies provides abundant resources for diversified cosmetic packaging. Glass, plastic, and metal are currently the main cosmetic packaging materials used. Glass has become the main material for high-end cosmetics due to its special bright effect and satisfactory weight, which exudes a sense of natural sophistication. For high-end cosmetics or cosmetics that are easy to evaporate and lose fragrance, such as perfume, etc., glass is generally used Glass bottles for packaging.
