Polycarbonate is mainly used for electronic applications that capitalize on its collective safety features. A good electrical insulator with heat-resistant and flame-retardant properties, it is used in products associated with power systems and telecommunications hardware. It can serve as a dielectric in high-stability capacitors. [6]
Examples include: the temperature of food products, the fat content of the food products and total time of contact with a surface. The safety of foam food containers is currently debated and is a good example of all three of these factors at play. Polystyrene may melt when in contact with hot or fatty foods and may pose a safety risk.
Disposable food packaging comprises disposable products often found in fast-food restaurants, take-out restaurants and catering establishments. Typical products are foam food containers, plates, bowls, cups, utensils, doilies and tray papers. These products can be made from a number of materials including plastics, paper, bioresins, wood and ...
Barcodes have been used for decades in packaging many products. 2D barcodes used in autocoding are increasingly applied to food packaging to ensure that products are correctly packaged and date coded. The ability of a package to fully empty or dispense a viscous food is somewhat dependent on the surface energy of the inner walls of the container.
The use of these compounds is diminishing due to restrictions on brominated flame retardants. The reaction of BPA with phosphorus oxychloride and phenol forms BADP, which is used as a liquid flame retarder in some high performance polymer blends such as polycarbonate/ABS mixtures that are used to form the casings for household electronics.

Plastic is one of the least sustainable, as about 16,000 chemicals are used to produce plastics, according to Enck. Coca-Cola bottles are the world’s No. 1 source of plastic pollution.
Many products use low-density polyethylene formed into plastic bags or plastic boxes. There are many makers of plastic boxes some such as Tupperware and Lock & Lock are known throughout much of the developed world. Metal containers. Longer-term storage or storage of items needing a higher degree of protection from the elements may use sheet metal.
Commodity plastics or commodity polymers are plastics produced in high volumes for applications such as packaging, food containers, and household products, including both disposable products and durable goods. In contrast to engineering plastics, commodity plastics tend to be inexpensive to produce and exhibit relatively weak mechanical properties.
