Abstract (en)
[origin: WO2015164986A1] A tear-off lid (10) has a removal opening (15) with a beaded rim and is designed such that prior to beading of the rim a plastic layer is applied to the collar of the lid ring in the form of a strip (32) of little thickness and preferably of less than 0.1 mm thickness. The invention thus allows in a cost-effective manner a good sealability of the cutting edge (31) of the tear-off lid and permits production thereof at high rates.
