This might be a deceiving statement, I think you would need to check the rating (the recycling number in the triangle on the bottom of the bottle). I looked at all my water bottles and they were rated #7 OtherDennys Fine Consumptibles said:Most water cooler water bottles are polycarbonate and make an excellent secondary.
1 PET - Polyethylene Terephthalate. Accounts for 20-30% of all plastic bottles manufactured. Most commonly found in 2-liter soda bottles, and water bottles.
2 HDPE - High Density Polyethylene. The most common plastic used in plastic bottle manufacture, about 50-60%. Usually found in milk and detergent jugs, shampoo and lotion bottles.
3 V - Vinyl/Polyvinyl Chloride.
4 LDPE - Low Density Polyethylene. Used in film plastics and plastic grocery bags.
5 PP - Polypropylene.
6 PS - Polystyrene. Used in disposable food service tableware, plates and cups. The "foam polystyrene" variety is often mistakenly called "Styrofoam" and is used for rigid packing material and peanuts.
7 Other All other plastic resins and multi-material plastics
Sorry, wasn't challenging what they were made of just questioning the O2 barrier properties of that grade (#7)of plastic especially for secondary.Dennys Fine Consumptibles said:I know for a fact they are polycarbonate. And polycarbonate IS listed as a #7.
