I. Iron Flask Overview

Iron Flask is an emerging water bottle brand established in 2016. During 6 years of growth, this brand has attracted many people’s attention, and has taken a certain share in the stainless steel drinkware market.

Since its start in 2016, Iron Flask has been committed to offering customers sustainable, clean and eco-friendly drinkware. Fortunately, this brand has chosen the right material–stainless steel instead of plastics to build their products, which serves as a solid foundation for future development. Iron Flask aims to make a difference by promoting reusable stainless steel water bottles in place of disposable plastic water bottles. Their commitment to protecting the environment as well as their high-quality drinkware gears have won people’s loyalty and trust.

In this article, KingStar, the leading insulated water bottle manufacturer, will share with you information about Iron Flask water bottles. Keep reading and let’s find some facts together.

II. What Are Iron Flask Water Bottles Made of?

Iron Flask water bottles are all made by 18-8 (SUS304) stainless steel. This brand has long discarded the adoption of plastic water bottles as they are not sustainable, recyclable and do harm to the environment. Iron Flask aims to promote the use of eco-friendly stainless steel water bottles, which also conforms to the trend of the times.

Plastic water bottles are normally non-biodegradable, which means they can not be decomposed by land or sea in a short period of time. According to a study conducted by a research team from Stanford University, the residual of plastics still can be found in the land after 400 years! The frequent use of plastic production exacerbates global warming, which has been recognized by the public. It is estimated that stainless steel water bottle business will become much more promising.

Iron Flask wholesale water bottles, mugs, tumblers in bulk and food jars are all made of stainless steel. These products are characterized by a double-walled insulation structure to achieve satisfactory insulation outcomes, things that can never be done by a plastic container. The durable material enhances the anti-impact property and enables the Iron Flask bottle/mug/tumbler to become way more stronger than a fragile plastic counterpart. What’s more, Iron Flask stainless steel drinking bottles are completely BPA-free, dispelling customers’ misgivings.

III. Do Iron Flask Water Bottles Keep Drinks Hot?

Yes, they do. Iron Flask water bottles apply double-walled stainless steel structures to their insulation system, which helps to improve the insulation performance. Additionally, there is a layer of premium copper plated on the inner stainless steel walls to further insulated the bottle. The replaceable lid, apart from making the bottle versatile, is also conducive to sealing the bottle. An Iron Flask water bottle is capable of keeping hot contents warm for up to 12 hours or cold liquids cold for almost 24 hours!

IV. Is Iron Flask Made in the USA?

No, Iron Flask water bottles, tumblers, mugs and food jars are all made in China. But, stainless steel water bottles made in China are not inferior ones, instead, they are of the highest quality. According to the stainless steel water bottle industry report, nearly 95% of the world’s stainless steel drinking bottles are manufactured in China. So what kind of advantages does China have in terms of stainless steel drinkware production?

Chinese water bottle manufacturers invented stainless steel insulated water bottles in the 1980s. After that, they have gradually introduced and invented manufacturing equipment, improved and optimized the production processes, and trained expert equipment operators. As a result, China is now home to a complete set of production equipment and unparalleled manufacturing experience. The competitive labor price and the drinkware price edge further cement China’s place in the global water bottle production industry.

In a word, KingStar and the other water bottle manufacturers in China can offer customers high-quality drinking bottles with relatively low prices, second to none. The agreeable prices together with the superior quality drive many world-famous water bottle brands to establish cooperation with suppliers in China. These celebrated brands include Yeti, S’well, Hydro Flask, Iron Flask, BrüMate, and so on.

V. Do Iron Flask Bottles Tumblers Dent?

Which water bottle brand has the most durable bottles and tumblers? Yeti, right? So do Yeti tumblers dent? The answer is “yes” for sure. Dents are inevitable. But some bottles and tumblers have a better resistance to dents and do not dent easily.

Iron Flask bottles and tumblers do not dent easily with regular use. In other words, yes, they do dent. In fact, there is no such product that can repeatedly withstand impacts or is dropped from a certain height for many times without any bump. And here we only talk about the durability in common situations. If customers choose to run over an Iron Flask water bottle with a car and complain the bad quality of it after the “test” (the poor bottle is definitely crushed!), things then become irrational.

Often, dents appear around the body and the bottom of an Iron Flask water bottle/tumbler. If it is a tumbler, then customers are advised to use it carefully as there is little they can do to better protect it. But if it is a water bottle, customers are recommended to buy a silicone boot that can protect the base of the bottle. Offering customers protective accessories can reduce the labor spent on after-sales quality issues.
