What are the basic knowledge of cosmetic glass materials - Maypak

Glass Containers processed on the basis of glass are widely used in the field of cosmetics and daily chemicals. They are very popular among users because of their high transparency and good hand feeling. However, there are several types of glass materials, and the choice of material is often linked to the product grade. For example, in the fragrance market, the main material of Perfume Bottles is crystal white glass, while the more common cosmetic and daily chemical glass in the market is made of high white glass. Most of the material materials.

1. Material Definition

Name: Glass

Main ingredients: Na2O CaO 6SiO2

Glass is formed by melting silicon dioxide and other chemicals together (mainly produced from: soda ash, limestone, quartz). It forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with an irregular structure.

2. Material Properties

a. Perspective, light transmission performance is good

b. Simple manufacturing process

c. The shape is free and changeable

d. High hardness

e. Heat-resistant, clean and easy to clean

f. Low tensile strength

g. Can be used repeatedly

3. Material category

Glass is divided into ordinary white material, high white material, super white material and crystal white material. Different material colors can directly affect the transparency and brittleness of glass products. The better the raw material is, the better the quality of glass products is. Prices also vary. The most common plain white material glass bottles use a lot of recycled materials (commonly known as broken glass) in the production ingredients, and the formula price of high white material and crystal white material is far higher than that of ordinary white material. High white material glass needs to choose fine material and quartz sand with less impurities and high density, while crystal white material is basically processed with quartz stone as the main material and silicon dioxide as the auxiliary material.

4. Manufacturing Process

In addition to the raw materials such as quartz sand, soda ash, feldspar and limestone, the forming of glass products also needs to add auxiliary materials such as clarifying agent, flux, opacifying agent, coloring agent, decolorizing agent, oxidizing agent and reducing agent. It is formed after melting and homogenizing, and then annealed.

5. Processing Method

The main processing methods of glass are various, including artificial blowing, mechanical blowing, extrusion molding, drawing and so on. Among them, the high-white material glass is basically produced by row machines in China, while the crystal white material is mostly produced by manual machines.

6. Application of Cosmetic Glass Packaging Materials

Glass containers for cosmetics are generally made of high-white materials, and high-end products also use crystal white materials, such as perfume bottles. Through deep processing, glass can be formed into packaging containers such as cream bottles, essence bottles, toner bottles, lotion bottles, foundation bottles, and essential oil bottles.

7. Sustainable Development

After the glass products are consumed by the market, they can be recycled and reprocessed, and then reused. They are green and environmentally friendly products.
