☆  At present, the mainstream iron pull ring material for easy-open lid, the material thickness ranges from 0.26 to 0.40, the current mainstream uses 0.26, 0.28, 0.29, 0.30, 0.38mm, and the strip width ranges from 27mm to 100mm. Customer requirements are determined. Mainly hot zinc coil + aluminum gray layer, the coating color can be adjusted according to customer requirements.

☆  The mechanical properties of the galvanized ring pull materials are in the range of 58-63, 65-70, 70-75 and above 75. The corresponding tensile strength target values ​​are 430±50Mpa, 450±50Mpa, 600± 50mpa.

☆  Wave shear coating iron is used in the production of easy-open lids for food packaging. The thickness ranges from 0.16-0.28mm. The Rockwell hardness is generally T3.5-T5 and DR7-DR8.
