plastic re-usable trays are better for the environment because the amount of toxins we are putting into the air by making all of that styrofoam is horrible
A reusable plastic lunch tray would be better for the environment compared to a styrofoam lunch tray. Styrofoam is not recyclable in most places and takes hundreds of years to decompose. In contrast, a reusable plastic tray can be used multiple times, reducing waste and resource consumption.

"Plastic" is broad term that can be used to describe anything from bread dough to Teflon. Certain types of plastic are readily biodegradable, but can take a long period of time to decompose. Decomposable plastic used in plastic lunch bags and similar usually have a starch molecule worked into their matrix and are said to decompose in a composter in a few weeks, Impervious plastics like Teflon are impervious to microbial and chemical attacks and will last essentially forever.
There is no 'official' lunch time.
That would depend on what your lunch was made of.
Lunch boxes could use any type of insulation, most lunch boxes use a flexible based Styrofoam with a plastic coating to prevent the disintegrating of the Styrofoam.
Using paper lunch bags helps the environment much much more than using a plastic bag.

Many plastic lunch boxes are made of PVC (plastic #3), which can contain contaminants such as lead, or leach chemicals like phthalates. If plastic is your best option, look for lunch boxes that are phthalate and BPA-free so they are not healthy
You can buy a box of 500 trays for about US$25, meaning they cost around 5 cents each. (The cost to the environment, of course, is much higher, as they lie in landfill for hundreds of years.)
