These are Crown brand 440ml aluminium beverage cans with 52mm ( 202 ) ISE lids. These can be seamed by our OKTOBER DESIGNS Model 7 and SL1 can seamers.
These have a shipping weight of 30kg as they are bulky, the box does not weigh 30kg
Please note that empty cans are extremely fragile and as such there is an industry standard wastage of 5%. That being said, very few dents occur on the flange so can still be successfully seamed.
