The advantages are: environmental protection and sanitation—degradable plastics are generally considered to be plastics that can be decomposed into low-molecular substances by sunlight radiation or microorganisms in the soil. In addition to being degradable, it should also be easy to process and satisfy use Required performance.
The harmful effect of sunlight on polymer materials is the combined effect of ultraviolet light and oxygen, so it is called photo-oxidative degradation. Taking polyolefins as an example, photooxidation often causes chain scission or cross-linking of polymers, accompanied by the formation of oxygen-containing functional groups such as ketones, carboxylic acids, peroxides and alcohols. Its degradation mainly comes from the catalyst residues in the polymer, and the initiation of peroxides and carbonyl groups introduced during processing.
Tennie Chen is responsible for sourcing and supplier evaluation, with a focus on balancing product quality, cost efficiency, and supply chain reliability. My role involves identifying trustworthy manufacturers, comparing quotations, analyzing total landed costs, and ensuring compliance with international standards. I always prioritize long-term partnerships over one-time deals, aiming to work with suppliers who can provide consistent quality, competitive pricing, and flexible solutions. When making purchasing decisions, I evaluate not only the product itself but also the supplier’s production capacity, lead time, and after-sales support, ensuring that every cooperation contributes to sustainable business growth.
