The latest quotation of plastic tableware classified by composition

Plastic tableware can be seen everywhere now. What are the plastic tableware classified by composition? Polyvinyl chloride, high density polyethylene, polypropylene, etc. However, what's the latest quotation for plastic tableware? Let's take a look at the specific situation.

Plastic tableware is classified by composition.

According to its composition, plastic tableware can be divided into the following categories:

1, polyethylene terephthalate (PET), made of ethylene. Commonly used as mineral water bottles, cola beverage bottles, fruit juice bottles, etc. Because it can only resist heat at 70℃, it is only suitable for hot and cold drinks, and it will deform if it is filled with high-temperature liquid or heated.

2. HDPE is suitable for bottles of food and medicine, cleaning products and bath products, shopping bags and garbage cans.

3. Polyvinyl chloride (PVC) is polymerized from vinyl chloride. At high temperature, when it comes into contact with grease, PVC plastics easily release phthalate esters and toxic vinyl chloride monomers that are not fully polymerized. The plastic wrap made of PVC has good transparency, strong adhesion and low price. What we see in supermarkets and hypermarkets is the film firmly attached to the box. According to its characteristics, it is only suitable for cold storage of vegetables and fruits, not suitable for putting fatty foods such as meat and cakes, and not suitable for microwave heating.

4. Low density polyethylene (LDPE) plastic film and preservative film have good waterproof performance, so they are used as inner films of milk boxes, beverage boxes and other paper packaging boxes. Because the low-density polyethylene plastic wrap will melt when it exceeds 1 10℃, if the food is wrapped with this plastic wrap and heated, some components in the plastic wrap will dissolve. Therefore, the plastic wrap should be removed before entering the microwave oven, at least the food should not be in direct contact with the plastic wrap. Low density polyethylene itself has no degradation performance, which is mainly limited by the current plastic limit order.

5. Polypropylene (PP) polymerized from propylene is more transparent and harder than polyethylene. Most of the boxes used for packaging in restaurants are made of PP, and plastic boxes can be heated by microwave oven.

6. Polystyrene (PS), which is polymerized from styrene, is often used for instant noodle boxes and fast food boxes in bowls. It is heat-resistant and cold-resistant, but it will release harmful substances if the temperature is too high, so don't put the bowl-shaped instant noodles in the microwave oven for heating, and try not to use it to hold hot food. At the same time, it can't hold strong acid (if it is fruit juice) and strong alkali substances, otherwise it will release styrene and accessories.

7. Polycarbonate (PC) synthesized from bisphenol A and diphenyl carbonate has excellent impact toughness, mechanical strength and good transparency, so it is known as transparent metal. It is often used to make kettles, cups, milk bottles, etc. In the process of making PC, raw material bisphenol A should completely become the structural component of plastic, and should not be released during use, but it is often impossible. A small part of bisphenol A will not be completely converted into plastic, but will be released into food when heated. Bisphenol A is an endocrine disruptor, which is particularly harmful to developing fetuses and children, and may lead to abortion, congenital mental retardation and mental retardation of infants and young children. Studies have also confirmed that BPA can interfere with and antagonize thyroxine and inhibit the secretion of testosterone, affect the sexual development of boys, hinder the formation of sperm, and thus may affect fertility. Therefore, we should be extra careful in use, including polycarbonate bottles, so as not to cause harm to the baby's sexual development.
