Refers to the sealing material applied to the inner side of the groove of the barrel bottom, cover or can bottom and cover, which plays a sealing role after the barrel or can body and the bottom and cover are curled. It is made of rubber, filler, resin, tackifier, etc., and is divided into two categories: water-based and solvent-based. Bolt cover

The maximum dimension parallel to the seam overlap measured from the outside of the seam. 9.12 Seam thickness
The maximum dimension perpendicular to the seam overlap measured from the outside of the seam. Countersink depth
The distance from the top of the double seam to the shoulder plane close to the inner wall of the seam, see Figure 38. Interior seam measurements 9.14
Refers to the structural dimensions of the various parts of the double seam after dissection, including body hook, cover hook, gap, overlap length, etc. See Figure 38. 9.15 Body hook
The length of the flanged part of the barrel or can body bent into a hook shape when the double seam is formed. 9. 16
coverhook
When the double curl is formed, the length of the cover hook bent inside the curl. Overlap length
After the double curl is formed, the length of the overlapping part between the body hook and the cover hook is measured by dissection. Overlap ratio
Indicates the length of the overlapping part between the body hook and the cover hook inside the double curl, that is, the ratio of the overlapping length to the overlapping length plus the length of the gap at both ends. 9.19
tightness rating
After the double curl is dissected, the uneven wrinkles on the periphery of the cover hook are observed with the naked eye to indicate the tightness of the double curl. It is graded and rated according to the ratio of the wrinkle-free length at the largest wrinkle to the entire cover hook length. Wrinkle rating
After the double curl is dissolved, the ratio of the maximum length of the wrinkle on the cover hook to the entire cover length. The wrinkle degree is in a corresponding relationship with the tightness, 100
meaning that the smaller the wrinkle degree, the greater the tightness. GB 13040-91
juncture rating9.21
refers to the phenomenon that the width of the cover hook formed by the cover hook at the can body seam during curling is insufficient. After the double curling is solved, observe the proportion of the effective cover hook to the entire cover hook width.

The process of spraying decorative and protective coatings on the surface of metal containers. 9.38 Lacquer blank with lacquer free margins In the manufacturing process of metal containers, in order to achieve better welding results, a certain distance of the joint welding part is left blank in advance when coating the metal plates. This kind of metal plate is called a blank coating plate. Lithograph printed and vanished blanks 9.392
The outer wall of the metal container is printed with colored ink patterns and varnish instead of label paper. This kind of metal plate is called a vanished iron plate. 101

9.40 Lacquer for striping After the barrel or can body is made of the hollow coating sheet, the coating gaps at the joints must be patched. The coating used is called the lacquer.
9.41 Internal coating Internal coating Coating applied to the inner wall of a metal container to prevent it from being contaminated or corroded by the contents. Rustproof lacquer
Coating applied to the outer wall of the bottom cover of a container to prevent rusting of a metal container is called external coating or rustproof coating. Over lacquer
Transparent coating applied to the protective or printed surface of a metal container. Sealing compound
Refers to the sealing material applied to the inner side of the groove of the barrel bottom, cover or can bottom and cover, which plays a sealing role after the barrel or can body and the bottom and cover are curled.
