Antimony free composition for laser marking thermoplastic compounds

It has been found, that when co-absorbing substances are added to intrinsic laser-absorbing bismuthoxide, the marking performance with a Nd.YAG-laser is improved or at least kept at the same level by reducing the costs. It is suspected, that the co-absorbing additive is not simply adding a contrast to the polymer by carbonizing the surrounding polymer but helping the bismuthoxide to couple the laser radiation and to ease the color change of this additive. This so found effect helps to cheapen the replacement of antimony trioxide and therewith have a safer and more sustainable solution for the current and future technology of laser marking.

CONTAINER COMPRISING A BODY WITH A MARKING ELEMENT AND A METHOD FOR PRODUCING A CONTAINER

A container for holding at least one pharmaceutical composition includes a body that includes a marking element at a location that allows identification of the container. A stress parameter of the body has a value less than or equal to a threshold value at the location. The threshold value is derived and/or derivable from a simulation result of a simulation based on a finite element method of the stress parameter for a surface area and/or a volume area of the body with or without the marking element present. A mean value is obtained or is obtainable by the simulation for the stress parameter for at least a part of the surface area and/or the volume area. The threshold value is the sum of the mean value and 1000% or less of an absolute value of the mean value.
