European glass manufacturer PLM takes the lead in introducing a glass coating machine

European glass manufacturer PLM Corporation was the first to introduce a glass coating machine capable of processing 15-90 bottles per minute. The order of the coating is the input bottle - acceptance - immersion in the base coating liquid - drying base coating - cooling - immersion in the final coating liquid - dry coating - moving bottle - coating hardening - cooling. This process provides two methods for glass bottle coating: one for single coating systems for decoration and the other for double coating systems for recyclable and disposable bottles. Single-coat bases are formulated with polyurethane for transparent, color-clear, matt, and color matte finishes. The first layer of the Shuangxing layer is called the base layer and is composed of a low-modulus synthetic rubber, which can prevent the bottle from being broken up or scattered into small pieces, and has a good anti-ultraviolet effect. The second layer consists of a high-modulus polyurethane that gives the bottle corrosion, impact and chemical resistance. As a result, the strength of the glass bottle is increased, the thickness of the bottle wall is reduced, the quality is reduced by 50%, and the production cost and transportation cost are accordingly reduced.
