Are our glass cosmetic jars recyclable?
Manufacturing glass bottles is a glass container processed on the basis of glass, which is widely used in the field of daily chemicals. It is very popular among users because of its high transparency and good hand feeling. Different glass materials directly determine the grade of the product. For example, in the fragrance market, the main material of perfume bottles is crystal white glass, while the more common daily chemical glass in the market is mostly high white.
1. Material Definition
name: glass
Main components: Na2O·CaO·6SiO2
Glass is formed by the fusion of silica and other chemicals (mainly produced from soda ash, limestone, and quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling, causing it to crystallize. 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 a random structure.
2. Material properties
It has good see-through and light transmission performance, a simple manufacturing process, a free and changeable shape, high hardness, heat resistance, cleanliness, easy cleaning, low tensile strength, and can be used repeatedly.
3. Material category-glass bottle for cosmetic
Glass is divided into ordinary white material, high white material, ultra-white material, and crystal white material. Different material colors can directly affect the transparency and brittleness of glass products. The better the raw materials, the better the quality of glass products produced. Color prices also vary. The most common white material glass bottle uses more recycled materials (commonly known as broken glass) in the product ingredients, and the formula price of high white material and crystal white material is much higher than that of common white material. The high white material glass needs to choose fine material and quartz sand with fewer impurities and high density, and crystal white material is basically made of quartz stone as the main material and silica as the auxiliary material.
4. Manufacturing process - glass bottle blowing
Using quartz sand, soda ash, feldspar, and limestone as raw materials, the molding of glass products need to incorporate some auxiliary materials, including clarifying agents, fluxes, opacifiers, colorants, decolorizing agents, oxidizing agents and reducing agents, etc. After mixing, After high-temperature melting and homogenization, it is processed and formed, and then obtained by annealing.
5. Processing method
The main processing methods of glass are various, including manual blowing, mechanical blowing, extrusion molding, drawing method, etc. Among them, high-white glass is basically produced by rank-line machines in China, while crystal white glass is mostly produced by artificial machines.
6. Application of cosmetic glass packaging materials
Glass containers for cosmetics are mainly made of high white materials, and high-end products also use crystal white materials, such as perfume bottles. Glass is further processed to form containers such as cream bottles, essences, toners, and essential oil bottles.
7. Sustainable development
After the glass products are consumed by the market, they can be recycled, reprocessed, and then reused.
