The manufacturing process of cosmetic packaging acrylic bottles has the following points:
1.Molding processing: the shell of an acrylic bottle used for cosmetics packaging is generally molded by injection molding, so it is also called an injection molding bottle. Due to its poor chemical resistance, it is generally unable to directly fill the paste. It needs to be equipped with an inner container to block it, and the filling is not easy to be too full, to prevent the paste from entering between the inner container and the acrylic bottle, to avoid cracking.
2.Surface treatment: to effectively display the contents of the website, the acrylic bottle body often adopts injection molding solid color, transparent natural color, and clear feeling. Acrylic bottle wall is mostly sprayed with color, which can reflect light and has a good effect. The surface of supporting bottle cap, pump head, and other packaging materials often adopts spraying, vacuum electroplating, electrochemical aluminum, wire drawing, gold and silver, secondary oxidation, and other processes to reflect the personalization of products.
3.Graphic printing: acrylic bottles and matching bottle caps are commonly used in silk screen printing, pad printing, bronzing, silver ironing, heat transfer, water transfer, and other processes to print the company's graphic information on the surface of bottles, bottle caps or pump heads.
Acrylic bottles are widely used in cosmetics packaging. Acrylic bottles are used in skincare products, such as cream bottles, lotion bottles, essence bottles, water bottles, etc.
