We are sure that you are not aware of potential risks associated with the drinking of bottled water. It is also sure that you are unaware on probable risks associated with the purchase of different kinds of water bottles. We bet you that no one has ever told you about the details about the ways of maintaining a good health. The major concern here is, in order to stay healthy, you should read the instructions indicated on the water bottled before purchasing one and drinking water from it.
Each and every water bottles should precisely indicate the materials used during the production of the water bottle. Since every kinds of plastics contain different kinds of chemicals ─ harmful most of the time ─ the indication of this information is very much important on any surface of the bottles.
Types of plastic used in the bottled are indicated in the form of numbers and letters, as shown in the illustration.
These are the meanings of the indications.
PET or PETE
One of the most frequently used plastics in consumer products, PET is highly used in packing water and soft drinks. While it is recommended for single use, there are chances of bacterial growth and leaching. Releasing of heavy metal and chemicals are higher in these kinds of bottles that are capable of affecting balance to the hormones. While only harmful chemicals can clean the bottles properly, these kinds of plastics are very difficult to decontaminate.
HDP or HDPE
HDPE is a rigid plastic normally used to make milk jugs, oil bottles and detergent, some plastic bags and toys. No chemicals are released from these types of plastics. It is recommended to buy water packaged in these kinds of bottles as they are safest among others. Water packaged in these bottles are considered to be safest.
PVC or 3V
PVC is a flexible plastic which is soft in nature. These types of plastic are used to make teething rings, cooking oil bottles, children’s and pets’ toys, plastic food wrapping and other consumer products. These types of plastics release two chemicals that are harmful for the hormones of human body. Experts recommend not to buy eatables stored in this type of plastic.
Use of this type of plastic is not possible while bottles are being produced though chemicals are not released through it. If you purchase any food items packaged in this type of plastic then you will be buying hazardous chemicals along with it
Polypropylene plastic is another type of plastic used to package food items because it is light weighed, tough and boasts heat-resistance qualities. It does not melt even if it is heated, thus is moderately safe. Especially, this type of semi-transparent and white-colored plastic is used in packaging syrups and yoghurt cups. This type of plastic is tested to be a good barrier against chemicals, grease and moisture.
Another plastic that is widely used is polystyrene, which is lightweight and is inexpensive and is used to make use-and-throw styrofoam drinking cups, egg cartoons, plastic picnic cutlery and take-out food containers. When heated, it releases carcinogenic substance and is not suitable to use as drink and food container.
PC or non-labeled plastic
Though this plastic is widely used for the production of food containers and sports water bottles, this is the most hazardous plastic ever made. Designed as a catch-all for polycarbonate (PC) and other plastics, reusing and recycling protocols are not approved for this kind of plastic. There is higher probability of chemicals leaching into food or drink products that are packaged in polycarbonate containers made using BPA (Bisphenol A).
