How long we can use reusable plastic water bottles?
Answer:
You can use plastic Botteles (PET bottles) as long as life time if you can keep it clean, hygine and leak proof. There is no expiry period in Chemical substance like plastic
If the plastic is thick (like Mangola or Maaza bottles)and you are using it regularly; then you can use it over 6 months.
But if the plastic of bottle is very thin (like AquaFresh bottles) don't use it over 1 month.
not more than months if drinking water/soft drik bottle.
if other water bottles, then try to change in three-4 months or also upto 6 months but better option change in every 3 monthsafter all health ka mamla hai.
As long as u can keep it clean & leak proof. Plastic has no upper limit of lifetime.
The expiry period of the PET type of bottles is longer than than the expiry period of the user.
These do not have any leachable constituents, nor do they biodegrade. If they do not disintegrate due to exposure to direct sunlight(UV radiation), and not punctured one can go on using them. Hygiene is important because plastics are prone to slime growth. Periodic cleaning in hot water will minimize this.
