Differences between steel and plastic bottles

At Cool Bottles, we are people committed to our environment. And in that sense, the difference between steel and plastic bottles has led us to focus our development on the former, for many reasons.

It’s not just about the material, but also its impact on your well-being and that of your family. When choosing between one or the other, you're making a decision that affects not just your daily hydration, but also the future of the planet.

Below, we’ll tell you all the details. But first, we invite you to check out this article we wrote about whether to choose a stainless steel or glass thermos.

Easily choose between plastic and steel bottles

Understanding the difference between steel and plastic bottles is the first step toward making a conscious purchase. Just because plastic containers have traditionally been present on supermarket shelves doesn't mean they’re beneficial—quite the opposite, actually.

In fact, although these types of containers are lightweight and practical, they often contain BPA and other chemicals that negatively affect your drinks—especially when exposed to high temperatures.

This becomes even more concerning when dealing with low-quality plastics, which require special care since lower prices generally go hand-in-hand with this kind of issue.

Environmental impact contrast

One of the most important differences between steel and plastic bottles is the environmental impact each one generates.

It's well known that plastic storage items can take up to 500 years to decompose. This undoubtedly worsens the already alarming global contamination issue.

On the other hand, steel bottles are 100% recyclable and can be reused for years without losing quality. That’s why we choose this type of material at Cool Bottles—not only are they super cool, but also sustainable.

Durability difference between steel and plastic bottles

But beyond these global aspects, steel bottles have several distinctive features that aren’t so obvious at first glance. Let’s break them down—you won’t want to miss them!

Temperature retention

Another difference that might not be obvious initially, but is very important, is their ability to retain temperature.

Cool Bottles' stainless steel bottles feature triple-layer technology that keeps drinks cold for up to 36 hours and hot for up to 18 hours, far outperforming plastic bottles. This makes them perfect for carrying your coffee or cold water all day long.

That’s not the case with plastic ones—in fact, under heat, they can significantly increase the internal temperature, which is pretty unpleasant.

Style and customization

In terms of style and customization, stainless steel bottles offer a much wider range of options than plastic bottles. It’s no longer a throwaway object—it becomes something that’s yours, a signature piece of your outfit.

Just take a look at our website and explore the Kids, Coolors, or Xclusive lines—each with its own style. We even collaborate with brands like Timpers so you can show your commitment to inclusion.

Difference in taste and smell

A noticeable difference between steel and plastic bottles is their effect on the taste and smell of beverages. Plastic bottles can retain the flavors of previously stored liquids, altering the purity of your drink—which also affects its aroma.

In contrast, Cool Bottles’ stainless steel bottles preserve the original taste of your drinks, whether it’s juice, soda, or water. They’re also easy to clean, which enhances this even further—as we explain in this post about how to clean stainless steel bottles.

Innovation and technology

And finally, we can’t forget such an important point—innovation.

While plastic bottles are relatively simple in design and functionality, Cool Bottles’ steel bottles incorporate technological advancements like triple-layer insulation and leak-proof lids that enhance the user experience.

These innovations not only improve temperature retention but also ensure greater convenience and efficiency in everyday use.

Remember, when choosing between a plastic and a steel bottle, you’re not just making a choice for your health and the planet, but also choosing from a variety of styles and features that suit your daily life.
