Coated Aluminum PP Cap Sheet Production Process

The PP cap is sealed aluminum beverage bottle, senior wine thread popular on the current market cap, which is characterized by convenient opening, sealing and excellent anti-theft performance, composite food hygiene standards, so in recent years, with the continuous improvement of production development, people's consumption level and the need for export packaging. Its output and sales have increased rapidly. With the rise of the PP capr, the coated aluminum PP cap sheet produced by Signi Aluminum Co., Ltd. has been successfully developed, put into production and popularized and applied, and achieved great success.

2. Coated aluminum PP cap sheet coating process
 
Currently on the market common aluminum cap with the white and gold two, the cap process is: after the first solvent cleaning out aluminum to improve the adhesion of coating layer, aluminum plate, aluminum plate deep-drawing performance; after treatment can be directly coated with golden oil, baking and curing after punching, incision, thread rolling and pressing different specifications of the change, become.
 
If the cap is white, the best first coated with a layer of 25 degrees of base oil, baking and then coated with white paint, this film adhesion resistance, deep drawing performance better. 【
Coated aluminum PP cap sheet
 
Pure white or golden cover, usually need no cover light, if printed text or logo logo, need to cover a layer of varnish, to protect the text or pattern, prevent mechanical scratches.
