In accordance with its composition, plastic tableware can be divided into the following categories:
1, polyethylene terephthalate (PET), formed by the collection of ethylene. Commonly used for mineral water bottles, Coke beverage bottles, juice bottles. Because it can only heat 70 ℃, it is only suitable for cold and warm drinks, if installed high-temperature liquid or heat will be deformed.
2, high-density polyethylene (HDPE), suitable for loading food and medicine bottles, cleaning equipment and bath products, shopping bags, trash.
3, polyvinyl chloride (PVC), from vinyl chloride polymerization. High temperature and contact with the oil Polyvinyl chloride plastic is easy to release phthalate esters and incomplete polymerization of toxic vinyl chloride monomer. PVC made of plastic wrap good transparency, not easy to break, strong adhesion, low prices, we in supermarkets, supermarkets to see the box on the stick is very strong film is it. According to its characteristics, it is only applicable to vegetables, fruits, cold storage, should not put meat, cakes and other foods containing more fat, nor for microwave heating.
4, low-density polyethylene (LDPE) plastic film and plastic wrap, good performance of the water barrier, so the milk to do the paper boxes, beverage boxes and other packaging boxes are used as internal film. Because the low-density polyethylene plastic wrap will appear more than 110 ℃ hot melt, so if the use of the plastic wrap wrapped in food heating, food in the plastic wrap will melt some of the ingredients out, therefore, into the microwave before the first preservation Film to get rid of, at least not let direct contact with food cling film. Low-density polyethylene itself does not have degradation of performance, today's "plastic limit" is the main limitation of it.
5, polypropylene (PP), made by the polymerization of propylene, transparency is also better than polyethylene, harder than polyethylene, the restaurant is mostly packaged with the box it, made of plastic box can be put into the microwave heating.lid and spoon rest
6, polystyrene (PS), made by the polymerization of styrene, commonly used in a bowl of instant noodles box, snack box. It is heat and cold, but the temperature is too high will release harmful substances, so do not bowl of instant noodles into the microwave heating, and try not to use it to install hot food, but also can not hold strong acid (such as juice) and Strong alkaline substances, or will release styrene and auxiliary materials.
7, polycarbonate (PC), which is bisphenol A and diphenyl carbonate for the synthesis of raw materials, has excellent impact toughness and mechanical strength, and transparency is very good, so known as "transparent metal." Commonly used in the manufacture of water bottles, cups, bottles and so on. In the production of PC process, raw materials should be completely into the plastic structure of bisphenol A component should not be released in use, but in fact often can not, there will be a small part of bisphenol A can not be fully converted to plastic, Is released into the food. Bisphenol A is an endocrine disruptor, the development of the fetus and children particularly harmful, may cause abortion, congenital mental retardation and infant mental retardation. Some studies have also confirmed that bisphenol A will interfere with antagonism of thyroid hormone and inhibit testosterone secretion, affect the boy's sexual development, hinder the formation of sperm, which may affect fertility. Therefore, the use should be especially careful, including polycarbonate bottle made of, so as not to cause harm to the baby's sexual development.usb endoscope inspection camera
