Stainless steel water bottles are a big trend in modern societies around the world. Insulated bottles are famous among the people, especially among those who want to carry their potable water. These are more suitable for tough people like sportsmen, athletes, campers, travelers, hikers and any others from different industries.

As per DIN 28400 Part 1: “Vacuum is the condition of gas when its pressure inside a container or density is lower than outside the container or simply, the pressure of the gas is below 300 mbar, lower than atmospheric pressure of the gas on the surface of the earth”. In vacuum based insulated bottles, thermal insulation effects happen due to thicker materials by decreasing thermal conductivity. In fact, if the gas pressure in panel goes on decreasing to the minimum level, then it will eliminate heat transfer. So, a thinner structure will also give an awesome performance and meet the proper condition. Key properties of double walled stainless steel water bottles are;

Raw Materials Used to Make Insulated Vacuum Stainless Steel Water Bottles

Stainless steel or plastic is the fundamental raw material for making insulated water bottles. This material used to make caps, glass and inner cup for pouring the liquids of different temperatures. The basic manufacturing process is;

Foam Used:

  • The initial form of foam is a liquid ball that arrives at a manufacturing factory. These balls combined together for a chemical reaction through heat.

  • This liquid material is a bit heated up to 23.9 to 26.7 Degree Celsius.

  • This mixture is brought to cool down and it forms the required type of foam.

Bottle Structure:

  • The manufacturers make the outer cap right after preparing the foam. The material of the cap may be plastic as well as stainless steel. The blow molding process is fine to make an outer cap of bottles with plastic material. For stainless steel outer cap, steel material is pounding in a specific shape to get caps.

  • The outer cap is fitted to the inner part during the assembly line procedure. It is a specific type of stainless steel or glass made filter made by stainless steel sheet, while it is put inside the outer cap.

  • Now, insulation added to the bottle. For cold insulated water bottles, the foam in liquid form placed between the cups and let it harden over time. For hot insulated bottles, vacuum machine releases the air between two cups of the bottle and sealed vacuum.

  • Silicone is sprayed on both cups by holding them together in single form and then these stainless steel water bottles are painted completely.

  • The company logo posted on the bottle by some sticking material.

  • Finally, these manufactured stainless steel insulated water bottles brought for quality inspection. In next, company wraps and packs them to distribute.


The Top/Cap:

Tops of these bottles are also blow molded, while they have stoppers which users can pull upward. Liquid flows out from a little hole that is also blow molded. Finally, a little hole is punched in the cap to let liquids flow out through this hole.

Quality Control:

This is a key step of manufacturing the insulated stainless steel water bottles. Quality of the bottles is checked out properly. Most insulated bottles are brought for quality control inspection process.

Benefits of Stainless Steel Material to Make Water Bottles:

BPA Free:

BPA is a toxin that comes into existence when plastic material or water bottles are heated up. Plastic water bottle softens release BBPA in hot summer, while this chemical will promote cancer in human beings. BPA can also affect the environment as well as human growth hormones. Further, insulated stainless steel water bottles are free of BPA due to no use of plastic material in the manufacturing of these metallic bottles. BPA may speed up male impotence, reproductive issues in women, diabetes and heart disorders. FDA has declared stainless steel bottles 100% free of BPA as well as odor. High-quality insulation and vacuum technology in these bottles save human body from BPA and its effects.


Good Insulation:

Stainless steel water bottles are 100% insulted with double walls of steel and vacuum between two cups. This insulation technique is far better and important than the rest of insulation forms. These water bottles are best for your cold and hot drinks as they are capable to keep your liquids at the right temperature for the next several hours. The Coldest Water Bottles can keep your drinks cold for next 36 consecutive hours, while these bottles are best to keep hot drinks warm for the next 12 hours.

Reducing Pollution Level:

Plastic water bottles contaminate the world’s environment. 91% of plastic bottles dumped to landfills or reached to oceans. However, it takes 400 years to decompose plastic water bottles and waste from the earth. On the other side, stainless steel insulated water bottles don’t contaminate the environment as they are reusable. Further, these bottles are 100% best for recycling process and make new types of stainless steel products. If you buy stainless steel water bottles, then you can use them as long as you want.


No Leaching of Material in Water:

All the metallic water bottles are not healthy and useful like stainless steel water bottles. In fact, aluminum, chromium, and iron are chronic metals that are widely used to make the water bottles. These metals have a natural quality to discharge or leach the metal effects to potable water you place in these bottles. In this way; you drink these metals along with your hot and cold drinks. Leaching process of these metals increases if you are using hot drinks. In this way; metallic bottle users drink toxins and get diseased seriously. On the other side, an alloy like stainless steel water bottles is free of such effects. These water bottles are made up of polished and furnished steel that doesn’t cause any leach of metal. So, your potable water is safe to drink. It means stainless steel water bottles are 100% healthy, useful and beneficial for users.

Highly Durable Water Bottles:

The durability of a water bottle depends on manufacturing material. Usually, plastic, chromium, and aluminum all metals have good durability, but not enough as stainless steel owns. That is why; stainless steel water bottles beat durability level once again. These bottles are solid and powerful in their structure that can last longer; even for decades. Anyhow, stainless steel water bottles win the awards for their performance, durability, and structure.


Best for Hydration Needs:

You need to drink plenty of pure and healthy water in a day to stay hydrated. For this; stainless steel water bottles are available in multiple designs, sizes, and capacities. You can use these bottles to carry potable water with you for your outdoor activities. These bottles let you drink healthy and fresh water the whole day and prevent dehydration successfully.

Plastic V/S Stainless Steel Water Bottles:

According to several researched the plastic bottles create many infections, disorders, and bacteria to attack human beings. These bottles keep affecting humans, living species, agriculture, animals and the environment from manufacturing to the decomposing age. On the other side, stainless steel water bottles are the best solutions compare to plastic bottles that cause many kinds of unhealthy things and critical effects on human life. You can never use plastic bottles longer due to their material and structure. On the other end, stainless steel bottles are best due to re-usability and long lasting durability. In fact, stainless steel bottles are better in all aspects than plastic water bottles.

Zero Use of Plastic:

Makers don’t use any type of plastic in making stainless steel water bottles from first to the final level of manufacturing. So, the entire manufacturing process of these water bottles is completely free of plastic material. Manufacturers also use metals and approved material to make caps/lids of stainless steel water bottles to meet health standard.


Quick Increase in Demands:

Demands for stainless steel insulated water bottles are growing consistently for the last few years. Some key reasons behind the increase in demands are;

  • Increase in health and environment safety awareness inspires the people on this planet to minimize usage of plastic material, products, and water bottles. That is why; they hunt for an excellent and best alternative. Stainless steel water bottles are long-lasting.
  • These smart and decent types of thermos flasks are very supportive and best for outdoor uses like camping, traveling, hiking and for athletes.
