Because it it is biodegradable (falls apart over time). This is good for the environment as most plastics take roughly 1000 years to fall apart. Unfortunately this also means that it can only be re-used over a short amount of time.
Two materials that can be combined to make biodegradable plastic bags are corn starch and PLA (polylactic acid). These materials are biodegradable, renewable resources that can be used to create environmentally friendly alternatives to traditional plastic bags.
NO all it takes is get a plastic bag then poor corn starch in it, next put corn oil in it, finely water, lastly seal it and put it in the microwave for 20 seconds NOW YOU HAVE PLASTIC!
Biodegradable plastic can be created by using natural materials like corn starch or sugarcane to make the plastic, which allows it to break down naturally in the environment.

You should NOT manufacture plastic bags because when you make them you release toxic gases into the atmosphere! And if people buy you have to make more and more.Note: Use re-usable bags! Plastic bags are bad for the environment!
There are several companies in various cities that make custom plastic bags. There are also websites like freedomplasticbags.com that make custom plastic bags.
Although corn flour and corn starch derive from the same part of the plant, they are NOT the same thing, and in cooking, they behave very differently. If you use corn starch to make tortillas, you'll get an inedible glob of goo. On the other hand, if you use corn flour in place of corn starch, you'll get gruel instead of gravy or sauce or pudding. Corn flour and corn starch should not be confused with (or used in place of) corn meal, which, although related, is a totally different product with a totally different purpose.

Generally, plastic bags are easier and less resource-intensive to produce than paper bags. Plastic bags can be mass-produced at a lower cost and require less energy and water during the manufacturing process compared to paper bags. However, plastic bags have a higher environmental impact due to their long degradation time and potential for pollution.
