Eco-friendly and economical material that breaks down into water, carbon dioxide and nutrient-rich degradable plastic within four to six weeks
Non-degradable plastics are mostly made of low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) followed by high density polyethylene (HDPE), polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC). ) developed and produced. These plastics are generally disposed of as solid waste, resulting in the formation of pollutants such as acid rain in the air, which are harmful to our lives.
Degradable plastics that exist in the US and Japanese markets include biodegradable polyesters such as polylactic acid, biodegradable PET, polybutene succinate/caproate, polyhydroxybutyrate/valerate, polyethylene succinate , polyester amides and polycaprolactones/blends; starches and their blends; and other plastics with degradability-enhancing additives.
At present, in addition to PBAT, PLA is also a key research project abroad.
Polylactic acid (PLA) is a new type of biodegradable material made from starch raw materials proposed by renewable plant resources such as corn. The starch raw material is saccharified to obtain glucose, and then fermented from glucose and certain strains to produce high-purity lactic acid, and then chemical synthesis method is used to synthesize polylactic acid with a certain molecular weight. It has good biodegradability, and can be completely degraded by microorganisms in nature after use, and finally generates carbon dioxide and water, which does not pollute the environment, which is very beneficial to protect the environment and is recognized as an environmentally friendly material. The treatment method of ordinary plastics is still incineration and cremation, which causes a large amount of greenhouse gases to be discharged into the air, while polylactic acid plastics are buried in the soil to degrade, and the carbon dioxide produced directly enters the soil organic matter or is absorbed by plants, and will not be discharged into the air. Does not cause greenhouse effect.
According to the understanding of CFI market, the international chemic BASF and Australian food packaging manufacturer Confoil have partnered to develop a certified compostable, dual-function oven-friendly paper food tray - DualPakECO On June 30, 2022,
The inside of the paper tray is coated with BASF's ecovio PS1606, a high-performance general-purpose bioplastic commercially produced by BASF. It is a renewable biodegradable plastic (70% content) blended with BASF's ecoflex products and PLA, and is specially used for the production of coatings for paper or cardboard food packaging.
This new certified compostable solution is an alternative to traditional PET packaging for ready-to-eat meals. Not only can this tray be heated in conventional ovens and microwaves, but it can also be refrigerated or frozen. They have excellent barrier properties to fats, liquids and odors, helping to maintain food freshness and taste.
Composting trials have shown that under commercial composting conditions, DualPakECO trays can decompose into water, carbon dioxide and a nutrient-rich compost within four to six weeks.
Recently, more and more international giants have participated in the research and development of degradable plastics. According to CFI, next year 2023 will be the year of mass application of degradable plastics.
