Plastic containers will be used in many places in this era, and many people are also willing to use plain cans to replace other products. So what is the use of plain containers? Where can I buy it? What is its development trend?

What are the development trend of plastic containers?
Each plastic can has a small ID card, a triangle symbol, usually at the bottom of the plain container. There are numbers from 1 to 7 in the triangle. Each number represents a kind of plastic container. They are made of different materials, and there are also different contraindications.
"No. 1" plastic can represents polyethylene terephthalate (PET, commonly known as polyester resin), which is often used to make mineral water bottles and carbonated beverage bottles. The beverage bottle is heat-resistant to 70°C when used, and is only suitable for warm or frozen drinks. It is easy to deform when it is filled with high-temperature liquid or heated, and harmful substances to the human body will melt.
"No. 2" plastic container stands for high-density polyethylene plastic (HDPE), which is mostly used to make containers for cleaning products and bath products. It is recommended not to recycle if cleaning is not thorough.
"No. 3" plain container stands for polyvinyl chloride (PVC), which is rarely used for food packaging and is best not to buy.
"No. 4" plastic can stands for low-density polyethylene plastic (PE), which is commonly used in the production of cling film and plastic film. Cling film is not very heat resistant. Generally, qualified polyethylene cling film will melt when the temperature exceeds 110 ℃, leaving some plastic preparations that cannot be decomposed by the human body. Therefore, avoid using cling film to wrap the food surface. heating.
"No. 5" plastic canister stands for polypropylene (PP) and is used to produce microwave lunch boxes. It can be put in the plastic box of the microwave oven and can be reused after careful cleaning.
"No. 6" plastic container stands for polystyrene (PS), which is often used in the production of bowls of instant noodle boxes and fast food boxes. It is heat-resistant and cold-resistant, but cannot be placed in a microwave oven, and cannot be used to carry strong acids (such as orange juice) and strong alkaline substances. It will decompose polystyrene which is harmful to the human body and is easy to cause cancer.
"No. 7" plain container stands for polycarbonate (PC) and others. PC is a material that is used in large quantities, especially in the manufacture of baby bottles, space cups, etc. It is easy to release the toxic substance bisphenol A, which is harmful to the human body. Do not heat it when using it, and do not expose it to direct sunlight.

The development direction of plastics can be summarized in two aspects. The first is to improve performance, that is, to modify existing varieties by various methods to improve their comprehensive performance; the second is to develop functions, that is, to develop polymer materials with optical, electrical, magnetic and other physical functions, so that plastics can have Photoelectric effect, pyroelectric effect, piezoelectric effect, etc.
At present, plastic cups and composite cups (outer PSP, inner PP, cover PS) are popular abroad for packaging cold and hot beverages, wine, and convenience food. France uses PE bottles to package fructose and yogurt, and Germany uses PC bottles to package milk. my country uses PE bottles for packaging medicines.
