Student from Karachi creates edible plastic

A student from Karachi University has created environment-friendly plastic from a marine plant. This type of plastic is edible and can be consumed without any harmful effect after mixing it with any fluid such as water.The only drawback of using it as shopping bags commercially is that it cannot hold high-temperature liquids like tea, because it dissolves in hot solutions. However, cold liquids like milk can be carried in these bags for short periods of time.
