Degradation studies on plasticized PVC films submited to

Among the irradiated plasticized poly (vinyl chloride), the PVC/DEHP film have shown the highest degradation due to chain scission, particularly when exposed to the dose of 25 kGy which is the sterilization dosage, used for medical and pharmaceutical devices and packaging materials.

Photodegradation of PVC | SpringerLink

The extent of this degradation depends primarily on the presence within the polymer of light-absorbing structures. Polymers containing aromatic or carbonyl groups in their monomer unit are likely to absorb the terrestrial sunlight (wavelength λ>290nm) and usually become photosensitive materials.

Laser marking on plastic - Precise and indelible | LASIT

In most cases, we recommend using a MOPA laser, meaning with variable pulse: thanks to the pulse duration control, this laser ensures maximum performance in the most difficult applications. The most common processes of laser marking on plastic are carbonization, color change, foaming and engraving.

For PVC, ABS, and polystyrene, both fundamental and green lasers show low transmission ratio and high absorption ratio, which ensures good marking. On the other hand, the transmission ratio for polyimide is about 30% with a green laser (532 nm) but more than 90% with a fundamental laser (1064 nm).
