In foreign countries, especially developed countries in Europe and America, the production and use of polypropylene woven bags are also very common. However, unlike in China, foreign countries place greater emphasis on the environmental performance of polypropylene woven bags. Many countries and regions have introduced strict environmental policies, restricting or banning the use of non-degradable plastic products.
Therefore, foreign polypropylene woven bag manufacturers have devoted themselves to the research and development of biodegradable materials. Some new biodegradable materials, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA), have been applied to the production of woven bags. These materials not only have good degradation properties but can also replace traditional polypropylene materials to a certain extent, thereby reducing environmental pollution.
