Biobased biodegradable plastics in modified materials for garbage bags are an emerging environmentally friendly material aimed at replacing traditional petroleum based plastics and reducing their impact on the environment. This material is mainly made from renewable resources and combines high degradability with good usability, making it suitable for the production of garbage bags. The following is a detailed introduction to biodegradable plastics:
1. Material composition
-Biobased polymers, such as polylactic acid (PLA), starch based polymers (such as polyvinyl alcohol PVA, polyhydroxyalkanoate PHA, etc.), are derived from renewable resources such as plants and corn.
-Modified additives: In order to improve the physical and processing properties of plastics, toughening agents, antioxidants, and other additives are often added.
2. Characteristics and advantages
-Biodegradability: These materials can be decomposed by microorganisms under certain conditions (such as composting environment), reducing persistent pollution to the environment.
-Thermal stability: It has good thermal stability during processing and can be processed using traditional plastic processing equipment.
-Mechanical properties: By modification, its tensile strength, tear resistance, and puncture resistance can be improved, making it suitable for carrying various types of garbage.
-Environmentally friendly: reduces dependence on fossil fuels and helps to lower greenhouse gas emissions.
3. Application Fields
-Household and commercial garbage bags: can be used for garbage collection in daily life, especially in environmentally friendly markets.
-Horticultural garbage bag: used for collecting plant waste and can be composted as an option.
-Medical garbage bag: Suitable for the medical industry, it helps to handle hospital waste and meets environmental protection requirements.
4. Market Trends
-With the increasing global attention to plastic pollution, the demand for biodegradable plastics is gradually increasing. Many companies and research institutions are committed to developing higher quality biodegradable materials.
-The government and environmental organizations also encourage the use of environmentally friendly materials, and many places have implemented plastic bans to promote the popularization of biodegradable garbage bags.
5. Challenge
-Cost: Currently, the production cost of biodegradable plastics is relatively high, which may limit their market promotion.
-Performance: Although modified, the performance in some extreme cases may still be inferior to traditional plastics.
-Degradation conditions: The effectiveness of biodegradation often depends on specific environmental conditions, and sometimes the degradation rate is slower in natural environments.
