Disposable fast food boxes have changed from foam boxes to environmental protection boxes. The original foam boxes were eliminated due to their high temperature resistance and damage to the geographical environment caused by the production process. Plastic lunch boxes, paper lunch boxes, wooden lunch boxes and melting lunch boxes are taken instead. Among them, plastic has the characteristics of lower side effect, higher dissolution point, strong extensibility, easy production and processing and inferior direct cost of objectivity, thus becoming a fashionable raw material for the production and processing of disposable fast-food boxes. PHB is a kind of thermoplastic polyester widely found in nature, especially in human cells. PHB has many physical and mechanical properties similar to polypropylene plastics, but it is biodegradable and biocompatible, and can be completely degraded into -hydroxybutyric acid, carbon dioxide and water in vivo.

Some bad manufacturers add plasticizer to facilitate processing, generally this plasticizer is soluble in oil, if it is a hot oil, more dissolved, so the oil in food, a small amount of plasticizer will be dissolved into the oil, and then transferred to the food, if long-term or excessive exposure to plasticizer, will have a certain impact on the body. The use of disposable food boxes should be distinguished between good and bad, qualified food boxes can be safely used. Should try to avoid the use of disposable food box containing high temperature food, Fried food, vinegar and cooking wine mixed food. When the product is used, oil seepage, heat deformation and heat odor should be stopped immediately. Therefore, it is suggested that consumers should try to choose disposable tableware that can be degraded.

Disposable cornstarch tableware is made of materials that are harmless to human body, and the production process does not cause pollution to the environment. The product quality fully meets the hygiene requirements of *** food. Let Shanxi Newell Environmental protection take you to see our environmental protection tableware below! 1, hard texture, not easy to deformation, pressure, can be used as a packing box. 2. Environmental-friendly tableware can be reused. No matter in restaurants or at home, environmental-friendly tableware is safe and healthy. 3, environmentally friendly tableware can withstand the high temperature of 110℃, and will not melt, will not produce any toxic and harmful substances, in the temperature of minus 20℃ will not break; 4, the appearance of environmental protection tableware exquisite, diverse styles, disposable tableware can not be compared;

We can distinguish the quality of disposable tableware from the following steps: first, look at the information on the production package, production date, shelf life, production license and number (QS logo), whether from a regular manufacturer; Again distinguish color, colorful try not to buy, dark color to pay special attention to, if there is an odor, the explanation is definitely a problem. In fact, if the product used in daily life is transparent, it can be safely used, because basically it is made of polypropylene and polystyrene raw materials, without any additives or additives. If it is milky white, please do not use it, because raw material or toner has been added in the process to reduce the cost. The implementation of the new national standard plays an important role in further standardizing the production and use of plastic disposable tableware. Newell's green corn starch cutlery on the basis of the introduction of foreign advanced equipment and technology, in the process of production, has a very strict process, through precision equipment 260 degrees high temperature once injection molding, uv * * * after disinfection, composed of automatic assembly line aseptic packaging, health, and a variety of data testing conform to the standard, to ensure the excellent quality of the product.

PHB/PHV copolymers are already available as Biopol. Biopol is composed of a range of different materials, when the PHV content is not more than 30, PHB/PHV is 89/11 when the strength and toughness of the copolymer reached good, such products can be used in food packaging, cosmetics, medicine, health and agriculture industries. Polylactic acid production is based on lactic acid. The traditional lactic acid fermentation mostly USES starch raw materials. At present, the United States, France, Japan and other *** has developed and utilized corn, sugar cane, beet, potato and other agricultural and sideline products as raw materials for fermentation to produce lactic acid, and then to produce polylactic acid. Corn is the raw material of biodegradable plastic polylactic acid.
