How long is the plastic bottle used for health, please look at details.

Now the plastic products in the market. Food packet from ordinary drinks bottle - everything is now being used in plastic !!
But how often should we use the plastic we are using or how often should we use it? Did you know that?
Maybe I did not even think about this issue. But yes, it should be considered. Because it involves our health safety.
If you look at the plastic bottle floor or packet wrapping to see the safety involved, the triangle will be a sign. This symbol describes how much of the bottle was made, or how good it is to use health.
According to the Krikon theory of plastic bottles,
By the number in that triangle, you can understand the amount of time and how much time you use the environmental impact of the bottle.
Some skinsets:

If there is 1 number in the triangle:
This means that the bottle can be used only once. Polyethylene terrestle plastic used in the bottle. It can be recycled or converted. Many such bottles are harmful to health.
If there are 2 numbers in the triangle:
Dense polythene is used in such plastic bottles. Usually these bottles are used to keep shampoo, detergent, car oil, and juice bottle. It is relatively safe. Can be recycled.
If there are 3 numbers in the triangle:
Usually these bottles are used to keep peanut butter. Such bottles should not be used more. Because these bottles are made from 'Polivinol chloride' or 'PVC'. In this, human body is susceptible to asthma problems, liver problems and cancer.
If there are 4 numbers in the triangle:
These types of plastic are very useful. In particular, lots of these symbols are seen in plastic packets. There are also these symbols in very expensive bottles.
If there are 5 numbers in the triangle:
Such signs are seen in ice cream cups or syrup bottles or food containers. These are absolutely safe and more usable.
If there are 6 or 7 numbers in the triangle:
These types of plastic are seriously harmful. It is called plastic 'red card'. Because these types of plastic are made in polystyrene and polycarbonate bisphenol. As a result, it creates hormonal problems among people. Continuous use of such plastic can increase the tendency of cancer.
So from now on all these signs, use plastic bottles or boxes. And keep everyone healthy and safe.
