Abstract (en)

A method for printing by means of a laser beam a character on an inside of a mono-component recipient closure, said closure being made of a plastic material comprising between 0,10 % by weight and 1,5 % by weight of a laser beam absorbent additive and a high density polyethylene or polypropylene and wherein said character is printed by having said material absorbing an energy emitted by said laser beam and situated in a range of 1J/cm<2> to 12J/cm<2>, in particular between 2J/cm<2> and 5J/cm<2> so as to cause a colour change on the location where the laser beam is incident. <IMAGE>
