Are Biodegradable Milk Tea Bags Really Degradable?

Biodegradable bags are therefore usually new plastics that are impact resistant and can be completely or partially dissolved in the natural environment by microorganisms such as bacteria, moulds and algae without causing environmental pollution. The principle of biodegradation is that bacteria or their hydrolytic enzymes convert polymers into small molecular fragments which are then further dissolved by bacteria into chemicals such as carbon dioxide and water.

With regard to biodegradable materials, different products have been developed and produced at this stage: firstly biodegradable epoxy resins and masterbatches include fully biodegradable epoxy resins, photobiodegradable masterbatches and composite biodegradable masterbatches. Secondly biodegradable plastic products include compost bags, rubbish bags, shopping bags, electronic equipment bags, agricultural mulch, cutlery, golf spikes and foam, plastic products usually include shopping bags, rubbish bags and office supplies.
