Know Your Plastic Bottles And Plastic Things:
When we look at the back of bottles then we can find that there is a symbol and a number with alphabets are present , this shows the chemicals used in making these products. 

Let's Understand These Numbers:

1. Polyethylene terephthalate(PETE)-
This is the most common plastic and also used to make cold drinks and water bottles too. This is to keep in mind that these bottles are made to be used for 1 time only. If 

we use these bottles again then it is possible that chemicals present in these bottles may mix with the materials and enter in body which is harmful for health. So don't use these bottles 2nd time.
Formula of Polyethylene terephthalate(PETE)is (C10H8O4)n
Density of Polyethylene terephthalate(PETE) is 1.38 g/cm³
Melting point of Polyethylene terephthalate(PETE) is 260 °C

2. High-density polyethylene(HDPE)-
This plastic is made from petroleum and is used to make plastic bags, oil bottles, juice bottles, butter and curd tubs etc. This plastic is opaque and hard in nature. This plastic is free from harmful chemicals and not affected in high temperature. It is recycled easily and so is safe for environment too. 
density of HDPE can range from 0.93 to 0.97 g/cm3 or 970 kg/m3.
Formula of High-density polyethylene(HDPE) is (CH2-CH2)n

3. Vinyl(PVC)(V)-
This is thermoplastic polymer and is used to make detergent containers, window cleaner bottles etc. These products are very dangerous for health and so it is advised to not used them. Recycling of pvc is not possible so is not good for environmental health too. 


4. Low density polyethylene(LDPE)-
This thermoplastic is also made from petroleum and is opaque in nature. This plastic is used to make shopping bags, bread bags etc. This plastic is not dangerous for health because it does not leave dangerous chemicals. 

5. Polypropylene(PP)-
This is thermoplastic polymer and is a hard and strong in nature. This is the best plastic and is safe for health. It is possible to recycle products made from polypropylene and so is environment friendly. It is used to made medicines bottles, case etc. 
Density of Polypropylene(PP) is 946 kg/m³
Formula of Polypropylene(PP) is (C3H6)n
Melting point of Polypropylene(PP) is: 130 °C

6. Polystyrene(PS)-
This is also a petroleum based plastic and is used to make insulation and packaging materials. we can see it in egg containers and disposable containers. It is very difficult to recycle this plastic and so is not good for environment. 
Formula of Polystyrene(PS) is (C8H8)n
Density of Polystyrene(PS) is : 1.04 g/cm³
Melting point of Polystyrene(PS): 240 °C

7. Polycarbonate-
This is most dangerous plastic because it leave BPA chemicals. It is also used to make water bottles. It is not possible to recycle this plastic and so is not good for environment.

Note About Plastic:
2, 4 and 5 Number plastics are safer for use because these are hard and strong. 
It must be kept in mind that we should not use cheaper plastic water bottles for our children because they are not made by good quality plastic.
