When the metal crown lid is popped open by the opener, beer foam spews out and the bottle lid goes to life's end. In most of the time throughout its life, the metal crown lid fights with gas pressure in the bottle and tries its best to fit with the bottle mouth. The bottle lid's latter day "fighting" capacity depends largely on its congenital energy. Baosteel's new anti-bending crown lid chrome plate has better sealing property, ensures beer and other beverage quality and prolongs shelf life. Since this change, the customer feedback is good and order quantity is expanding gradually.
Metal crown lid is consumable. In the situation where resource and environmental issues are getting increasingly grim, the thinning and strengthening of metal crown lid has become the industry development trend. This requires that material supplier continues to develop raw material which is thinner, with higher yield strength and better processing properties.
Baosteel has many years of crown lid steel production history. While ensuring performance, it continues to increase R & D, make materials thinner and reduce cost for users. As the current food safety requirement is getting increasingly demanding, at the end of last year, some user asks Baosteel to increase its anti-bending performance on the basis of the original metal crown lid thickness, so that the metal crown lid will have better sealing property.
To further meet the needs of users, under the leadership of Manufacturing Management Department, Baosteel cooperates Steel Smelting Mill, Hot Rolling Mill, Cold-Rolled Sheet Mill, Research Institute, Customer and Product Service Department and Sheet Sales Department and sets up special research team. It improves product performance from steelsmelting ingredients and cold rolling whole process. In user testing, the new anti-bending metal crown lid chrome plate anti bending strength feedback is good.
