The garbage bag is designed reasonably, easy to carry, and can be easily lifted, making it very convenient for both taking out garbage and throwing away waste. The capacity of a portable garbage bag is usually larger than that of a regular garbage bag, which can accommodate more garbage and reduce the frequency of bag replacement, saving time and effort.

There are various new types of plastics available: photodegradable plastics, biodegradable plastics, light/oxidation/comprehensive biodegradable plastics, carbon dioxide based biodegradable plastics, and thermoplastic starch resin degradable plastics.
