Most reusable plastic bottles are claimed to be free of BPA. That was until studies showed that the plastics used are linked to hormonal disruptions within humans. The FDA reckons that BPA is safe at lower levels.

Fortunately, not all plastic bottles use BPA. The only issue is that manufacturers have replaced them with other things that we don’t know much about.

What about stainless steel water bottles? Well, in some cases, the innards of these bottles are either lined with resin, epoxy, or plastic. It is best to check if the bottle you intend on buying is not lined with one of these.

So, how will you know for certain which insulated water bottle material is best? Read along to see the different materials used and which you would like to carry with you.

Tritan Copolyester is a comparatively new material that came onto the market during 2007. High energy and thermal insulation are among some of its features. It is also dishwasher safe and resistant to stains, tastes, and odors. Tritan water bottles have quite a high desirability and a competitive price point as opposed to the stainless steel and glass materials.

Stainless Steel bottles are commonly made from stainless steel that comply with food-grade standards.

As stainless steel involves the use of nickel, individuals who are prone to allergies should avoid them.

Many consider glass water bottles as the purest material to use for drinking water, though it comes at a high price tag. Glass water bottles are not safe for children and often have restricted printing capacities. However, lass water bottles feature trendy silicone covers, which serve as additional bottle protection. Glass bottles are prevalent, as BPA does not form part of materials used.

Aluminum bottles are coated with resin, enamel, epoxy, or polymer. This is generally because aluminum tends to react with some liquids. Most factories do not reveal liner items and will assess and uphold food-grade liners that are BPA-free. Aluminum water bottles have always been cost-effective alternatives to stainless steel and, therefore, are obvious choices for long-lasting water bottles made of metal.

Not as heavy as stainless steel

Inexpensive

Higher actual value compared to plastic

Can be dented a lot easier

BPA-Free Plastic is the plastic most commonly used in affordable, custom made water bottles. There are many different plastics types ranging from PETE, HDPE, LDPE, and polypropylene. While the proper names are lengthy and will twist one's tongue. they're all still plastic. Tritan copolyester is a representative of this group as well.

Some may be recycled, but this depends entirely on the bottle collecting facility. Plastic bottles should never be thought of as fully recyclable. Most plastic water bottles apart from BPA are CPSIA licensed for use by children but this should never be taken for granted.

Even if two bottles look the same one might not have endured the stringent testing desired to be approved by CPSIA.

Material is very light

Features a variety of colors and is inexpensive

Makes an excellent gift for fundraising purposes

Might not be recyclable as assumed by many people

Needs to be hand washed and is not dishwasher safe

How you go about choosing your best insulated water bottle should be based on various health factors including how much weight you can bear and your fashion preferences. Your best option is to find a brand you think can hang on to for the longest time.

All of the insulated water bottle materials, except for BPA, carry minimal risk. The main criteria to pay attention to is to ensure everyone’s safety. Therefore, use your water bottle for drinking water only.
