Cosmetic packaging typically includes bottles, glass bottles, essential oil bottles, etc. Some packaging bottles are painted or branded with brand information. To not compromise the design of these bottles, the paint marking should be easily visible, usually on the bottom. Information like production date, batch number, and shelf life can also be spray-painted. The machine operates stably, with fast painting speed, accurate and aesthetically pleasing prints. It accommodates various bottle sizes, from large to small.

Place cosmetic bottles on the conveyor belt, and each bottle will be automatically sprayed with the nozzle without any manual intervention. It can also print barcodes, QR codes, and other traceable information to meet the coding needs of various industries. The surface of the glass bottles is coated with an organic paint (colors, additives, etc. added to the glass paint), achieving the requirement of rich colors on glass packaging bottles and enabling various effects such as glossy, matte, pearl, transparent, and gradient.

Cosmetic glass bottles are coated with a top layer of paint, where the solvent of the undercoat evaporates and bursts through the topcoat, releasing the paint. The topcoat leaves small holes due to its inability to level and seal. Solvent evaporation is quick: surface dry generally exceeds 10 minutes, usually around 15 minutes. Overcoating too thickly once: the surface evaporates too quickly, causing inner gas to accumulate, burst through the topcoat, and form. Reduce thickness, increase coats.
