The importance of using degradable and Eco-friendly lunch boxes
Plastic is a material that we often encounter in our lives. The main varieties include polyethylene, polypropylene, polyvinyl chloride, polystyrene, etc. Many plastics will release toxic substances at high temperatures, and there will also be micro-organisms in the natural decomposition process. Plastics and toxic and harmful gases are produced, and the world has reached a consensus on the harm of white pollution. They are actively promoting the policy of banning plastics and limiting plastics.
Hazardous substances in plastics are harmful to health
We can still see many disposable plastic lunch boxes and non-food-grade plastic bags used to hold food around us. When the temperature reaches 65℃, the harmful substances in the plastic will penetrate the food, which will affect the human liver. Kidney and central nervous system damage seriously affect our health.
Therefore, a non-toxic and sustainable new alternative material is urgently needed. Poly-lactic acid has gradually appeared in people’s field of vision.
Poly-lactic acid material
Poly-lactic acid is a non-toxic, harmless, biodegradable polymer material with good thermal stability. It can be processed in various ways and produce disposable lunch boxes, cutlery, spoons, straws, agricultural film, and plastic bags. Wait. In addition to being biodegradable, the food packaging products made from it have good bio-compatibility, food safety, strength, and heat resistance. They are green, safe, and Eco-friendly, which can effectively ensure food safety. The raw material of poly-lactic acid comes from bio-based, and its carbon footprint is only about 10% of that of traditional plastics. For every ton of poly-lactic acid material used, about three tons of carbon dioxide can be reduced year on year.
Raw materials of poly-lactic acid
Poly-lactic acid is a polymer material synthesized from renewable resources such as corn and straw as raw materials, fermented to produce high-purity lactic acid, and then synthesized by biotechnology. Poly-lactic acid was first used in the medical field to produce bio-absorbable sutures, bone nails, cardiovascular stents, etc. Poly-lactic acid can be hydrolyzed into lactic acid in the human body and finally absorbed by the human body as energy. It is non-toxic and harmless to the human body. It is a safe,Eco-friendly, low-carbon degradable material.
Because of its non-toxicity and good mechanical properties, poly-lactic acid can become a high-quality material for making Eco-friendly tableware and Eco-friendly packaging. Created into high-performance,Eco-friendly degradable lunch boxes, degradable plastic bags, degradable food bags, etc., the categories are complete, which can fully meet the market’s requirements for safe,Eco-friendly, and low-carbon food packaging.
Two factors for food quality assurance
Food quality consists of two dimensions: the food itself and the containers, materials, and auxiliaries that directly contact the food. Disposable foamed plastic lunch boxes and non-food-grade plastic bags for food seriously affect the quality of our food, and other plastic products will also seriously harm the already fragile ecological environment.
Therefore, food and catering enterprises can use non-toxic, healthy, and degradable new poly-lactic acid materials for plastic prepackaging bags and boxes for bulk fresh food, cooked food, pasta, and other commodities. This move can promote the transformation of enterprise food packaging materials and promote sustainable development, which is in line with the national development strategy.
