The most basic process for making cosmetic packaging is glass packaging manufacturing. The raw materials for making glass are generally quartz sand, sodium carbonate, and limestone. Mix these raw materials in a certain proportion, melt them in a high-temperature furnace, and then use a fiberglass machine to adsorb the melted glass onto the fibers. After rapid cooling, form glass tubes or discs. 1. Forming The glass tubes are cut, heated, and blown into different shapes of glass bottles, such as circular, square, trapezoidal, etc. 2. Cutting Cut the glass tube or disc into the desired length and use a cutting tool for cutting. 3. Heating Put the cut glass tube or disc into a special heating furnace and heat it to a certain temperature to soften the glass. This can make the bottle easier to shape during blowing, while also reducing the probability of producing bubbles and burning points. 4. Blow molding After heating, a certain amount of gas is blown into the interior of a glass tube or disc through a glass blowing tube, causing it to expand into the shape of the bottle body. When blowing, different shapes of glass bottles require different blowing tools. Then use a machine to modify the shape of the bottle to increase its aesthetics.  

Silk-screen printing refers to the method of obtaining graphics through scraping and printing using screen hollowed out boards and printing materials. During the printing process, the ink on the printing plate leaks from the through-hole of the layout to the substrate under the pressure of the scraper, forming the same image and text as the original manuscript. It originated in China and has a history of over 2000 years. At present, there are semi-automatic screen printing machines and fully automatic screen printing machines for cosmetic glass bottles. The fully automatic screen printing machine has higher requirements for bottle shape, but the output is higher. As a brand, when selecting cosmetic glass packaging materials, attention should also be paid to the selection of bottle types. Irregular bottle types will have more restrictions on the printing position. Before designing, you can communicate with the packaging factory to obtain the cutting line of the glass bottle to avoid design changes and wasting time.
