Does mechanical stress cause microplastic release from plastic bottles?
Dear Alwielland Q. Bello,
Microplastic are the fragments of plastics that wear out of the bottles in the size between 1-5 mm.
Considering the mechanicals stresses, neither tensile, nor compression or torsional can cause microplastic, unless the material breaks during the forces applied.
Only on failure/ breakage, it is possible that the bottle gives out microplastic.
Thank you
The study by Anna Wrinkler found that after opening and closing the bottles for number of times, there was a considerable increase in the occurrence of microplastic particles on the surface of the plastic material. And exposure to mechanical stress, show that the inner wall surface of the bottles did not show any stress cracks.
