Polypropylene nonwovens are used in many fields such as medical care, hygiene, personal protective equipment (PPE), construction, agriculture, packaging, and others. However, while providing convenience to people's lives, they also place a great burden on the environment. It is understood that its waste takes hundreds of years to completely decompose under natural conditions, which has been a pain point in the industry for many years. With the increasing awareness of environmental protection in society and the advancement of industry production technology, the nonwovens industry is actively deploying sustainable products and technologies to minimize the impact on the environment.
Since July 2021, according to the EU's "Directive on Reducing the Environmental Impact of Certain Plastic Products” (Directive 2019/904), oxidative degradable plastics have been banned in the EU because of their disintegration to produce microplastic pollution.
Starting from August 1, 2023, restaurants, retail stores, and public institutions in Taiwan, China were banned from using tableware made of polylactic acid (PLA), including plates, bento containers, and cups. The compost degradation model has been questioned and denied by more and more countries and regions.
Committed to healthy human breathing and providing cleaner air and water, Medlong JOFO has developed PP biodegradable nonwoven fabric. After the fabrics are buried in the soil, dedicated microorganisms adhere to and form a biofilm, penetrate and expand the polymer chain of the nonwoven fabric, and create breeding space to accelerate decomposition. At the same time, the chemical signals released attract other microorganisms to participate in feeding, greatly improving the degradation efficiency. Tested with reference to ISO15985, ASTM D5511, GB/T 33797-2017 and other standards, the PP biodegradable nonwoven fabric has a degradation rate of more than 5% within 45 days, and has obtained the Intertek certification from the global authoritative organization. Compared with traditional PP spun bonded nonwovens, PP biodegradable nonwovens can complete degradation within a few years, reducing the biodegradation cycle of polypropylene materials, which has positive significance for environmental protection.
Medlong JOFO biodegradable PP nonwoven fabrics achieve true ecological degradation. In various waste environments such as landfill, marine, freshwater, sludge anaerobic, high solid anaerobic, and outdoor natural environments, it can be completely ecologically degraded within 2 years without toxins or microplastic residues.
In user usage scenarios, its appearance, physical properties, stability and lifespan are the same as traditional non-woven fabrics, and its shelf life is not affected.
After the use cycle is over, it can enter the conventional recycling system and be recycled or recycled multiple times, which meets the requirements of green, low-carbon, and circular development.
