What really makes water bottles cheap depends on what they are made of. Of course, the higher quality a material is, the more costly the product will be, in the same way that those cheap water bottles would naturally be made of poor quality materials, some even on discount water bottles. The public must be warned though that many of these cheap materials are made of highly toxic substances that could be fatal when absorbed by the body in large amounts. So, we might be wrong after all in thinking that we will be saving money when we buy a cheap water bottle when in fact, it is likely to happen that we would be spending more later on due to some long-term health repercussions caused by life-long accumulated intake of the harmful substances. One way to avoid these harmful chemicals is to use a Klean Kanteen water bottle.
One such noxious chemical a person must be wary about is Bisphenol-A (BPA), which can be found in some polycarbonate plastics usually in cheap water bottles. BPA is widely used in the manufacture of dental sealants, CDs and DVDs, eyeglasses, jars, bottles and other wholesale water bottles because of its natural characteristic to make plastics very hard and firm. The use of BPA on some plastic wares would be an effective cost-saving measure for manufacturers because it is a great alternative to more costly materials, which similarly gives them the appearance they want for their product. Thus, the products turn out to be cheap when sold and allows for cheap water bottles to be created.
Studies show that BPA has been associated with reproductive failures and faulty pregnancy of women; neurological and behavioral birth defects; and some feared diseases such as obesity, diabetes and cancer, particularly of the prostate and breasts. These studies were based on the results of animal tests showing that BPA leaks from polycarbonate products and cheap water bottles used to contain food and water lead to a chromosomal abnormality known as Aneuploidy, which is an error in the cells’ divisions. More studies show that the older the polycarbonate plastic is, the faster the BPA leakage would be. The BPA’s release could also be heightened by heat absorbed by cheap water bottles. As a result, one of the world-renowned sports bottle manufacturers, Nalge Nunc International, has phased out its outdoor line of polycarbonate Nalgene water bottles containing BPA.
On the other hand, some substances that one must find in cheap water bottles, or in any other food or drink container, which are found to be safe to humans include the following: Copolyester, which is the new polycarbonate that does not contain BPA, High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polyethylene Terephthalate (PET, PETE), Polyvinyl Chloride (PVC, Vinyl), Polypropylene (PP), Polystyrene (PS), Stainless Steel and Aluminum.
Again, it might be argued that the cheap water bottles and collapsible water bottles produced or purchased only have very small amounts of BPA content. It is worth mentioning that the reported possible health effects of this toxic substance are long-term and it is the long-time accumulation of the said chemical inside the body, combined with other harmful matters caught from other various sources, that makes a person unhealthy and sick.
