Styrene oligomers in polystyrene containers used for food packaging have been found to migrate into the food. [112] Another Japanese study conducted on wild-type and AhR-null mice found that the styrene trimer, which the authors detected in cooked polystyrene container-packed instant foods, may increase thyroid hormone levels.

It is used to provide a high optical appearance and is mostly found in food and display packaging. Styrene-based copolymers (SAN, AMSAN, ASA, MABS) and blends (ABS/PA, ASA/PA, ASA/PC) are thermoplastic resins that are mainly used in various technical applications, such as vehicles, garden equipment, tools, appliances, consumer electronics ...
Styrene is named after storax balsam (often commercially sold as styrax), the resin of Liquidambar trees of the Altingiaceae plant family. Styrene occurs naturally in small quantities in some plants and foods (cinnamon, coffee beans, balsam trees and peanuts) [7] and is also found in coal tar.
Plant height in okra was significantly increased with black plastic mulch use compared to those grown in bare soil. Evaporation from soil accounts for 25-50% of water used in irrigation , using plastic mulch prevents much of this evaporation and thus reduces the amount of water needed to grow the crop. [ 8 ]
According to American Cancer society the use of polystyrene is safe for food services . [11] Styrene is considered by both the EPA and IARC to be a possible carcinogen. [12] [13] It poses a health risk to workers involved in the production of styrene and polystyrene items, and industries have a compliance program to deal with liabilities.

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.
