Why does my glass water bottle have an expiration date

Great! Share this article  

Yes, glass water bottles do have an expiration date. You can find the expiration date on the bottom of your bottle. If you see an “M” followed by a four-digit number, then the bottle is made out of borosilicate glass and has a longer shelf life than regular soda-lime (or non-tritan) bottles. Some companies also put “4y” or “24m” on their products as well, which means they expire within 4 years or 24 months from when they were manufactured. These dates aren't really something to worry about, though; glass lasts forever so long as you don't drop it on concrete!

Yes, glass water bottles do have an expiration date. It's on the bottom of the bottle and it is typically a number like 10 or 20. The number represents the year it was made, so a 21 means that your glass bottle is from 2021 and can last at least another decade before needing to be replaced. The expiration date doesn't mean much for glass water bottles because they're not subject to bacterial growth like plastic bottles are.

The expiration date can be found on the bottle's bottom.

It's usually in the form of a sticker or metal tag on the bottom of your bottle with letters and numbers (Example: 2018-10-11). If you are unfamiliar with these types of dates, you may think that it's just an arbitrary date set by someone. However, it actually has some significance behind it!

If you're still having trouble finding where this information is located on your water bottle or if your container doesn't have any sort of label at all, don't worry—we've got some tips for that too!

The expiration date actually isn’t a concern for glass water bottles.

Glass water bottles last forever.

Plastic bottles don't last forever.

Glass water bottles are made of natural materials, not synthetic materials or chemicals, like plastic water bottles are.

Glass is a natural material and doesn't contain any chemicals that can leach into your water over time (like BPA), so there's no need for an expiration date on glass water bottles!

Glass lasts forever, but plastic doesn’t.

Glass is a very durable material. It lasts forever, and it’s not going to break down or leach chemicals into your water like plastic can. The reason why you see an expiration date on your glass bottle is because it’s made of the same materials as the plastic bottles that you use at home, which means they can break down over time. Glass doesn't need an expiration date because it won't break down like plastic does!

If you want to get technical, there are two different types of glass: soda lime glass and borosilicate glass. Soda lime is used for most commercial bottles (like we see in stores), but borosilicate has been found by many health professionals to be a better choice when drinking from containers that could potentially contain harmful chemicals such as BPA (bisphenol A). BPA has been linked to several dangerous health effects including obesity and cancer; however, this only occurs when someone drinks large amounts of contaminated liquids over time

Plastic bottles can even leach chemicals into your water or glass when you put them in the dishwasher together.

If you don't have a dishwasher, washing your bottle by hand is fine. But even then, some care should be taken when cleaning plastic water bottles.

If you are using a glass or metal water bottle, it's best to avoid putting them in the dishwasher together with any other items that might leach chemicals into the water. This includes plastic bottles and aluminum cans—you may want to wash these items separately from your glass or metal container for best results.

Even though glass water bottles have an expiration date, they last forever, so you don’t need to worry about it.

You can be sure that your glass water bottle will never go bad, because it is made from sand. Sand is a natural resource that has been used for thousands of years to make glass bottles.

If you have a glass water bottle with an expiration date, don’t worry. It’s not something that you need to concern yourself with. The expiration date is a precautionary measure so people who may not know much about the material used in their bottle don't use it after its lifecycle has ended (for example, if they dropped it on the ground). If your bottle isn't damaged or broken, then you can use it for as long as possible before replacing it with another one!
