It is very easy to recognize because it is the typical plastic boxes of patties of fast food establishments. The power is also used to transport frozen food boxes.
It deteriorates easily and is highly pollutant, so it should not reuse for food use. There are also some studies indicating that it contains substances that may be carcinogenic and cause reproductive problems, so precaution is recommended to prevent its use.
Type 7. Other plastics and composite materials. The controversial Bisphenol A.
This group encompasses materials as polycarbonate (PC) that are manufactured CD’s and DVD’s or children’s bottles or new generation of biodegradable plastics made from vegetable starch (PLA). The use of polycarbonate in power is from some time in the spotlight, since it contains Bisphenol A (BPA), a toxic substance that could be transferred to food in contact with the container, mainly if it is subjected to high temperatures.
The packaging plastic type 7 are not reusable, but labeled as PLA biodegradable, i.e. are not recycled but are compostable.
In conclusion, we can reuse the types 1, 2, 4 and 5 plastic containers, provided that we maintain proper hygiene standards and do not put food in containers that were not originally designed for food use.
