What’s the Difference? Double Wall Insulated vs Single Wall Water Bottle
The single wall stainless steel bottle
- It’s made by stainless steel or plastic or silicon, any material but only single wall for your drinking.
- You can feel hot or cold when touching the surface of the single wall bottle, hence you might feel too much cold with ice water in Winter day or too much hot for your coffee.
- Different custom graphic can apply on the bottle with printing, laser engraving
- It’s safe and healthy as long as its raw material and manufacturing processes is safe and clean.
- It’s lightweight, easy to take it on the go, lower prices which is good option when with low budget.
The double wall stainless steel bottle
- It’s usually made by Stainless Steel and with Double Walls
- There’s a vacuum insulated layer between the double walls to enable the bottle keep ice cold for 24 hours and hot for 12 hours as heat energy can not penetrate through the vacuum layer where is no air.
- You can enjoy hot coffee with a double wall vacuum insulated bottle for 6 or 12 hours up at cold Winter day, also enjoy ice cold beer with slow drinking at the beach with your friends/family in hot summer days.
- Custom graphic pictures can be applied on the bottle with printing, laser engraving, or embossing.
- It’s double weight of a single wall bottle, also double prices, but it is worthwhile.
How to Wash My Stainless Steel Bottle?
- Hand washing. Use warm water with dish soap to clean the surface of the bottle, and with soft brush to clean inside of the bottle to achieve complete cleaning.
- Dishwasher washing. You can put the stainless steel bottles into a dishwasher but Separate caps & bottle & sealing gasket to avoid any damage and have complete cleaning. Don’t worry the heat inside dishwasher would damage the vacuum insulated double wall stainless steel bottle, it’s fake news, dishwasher washing won’t damage your bottle technically.

What’s BPA, Am My Bottle Is BPA Free?
Bisphenol A (BPA) will be released from water bottle made by plastic material (except for #5 plastic “Polypropylene”) especially with hot water/coffee. It’s generally known that BPA would pose threat to the health of baby/children.
It’s recommended to use GLASS BOTTLE, which is completely healthy. However, it is easy to be broken when dropped accidentally, not physical safe for young children using alone.
The best choice is Stainless Steel water bottle, it’s completely safe and healthy without BPA or any toxic issue, and it’s also environment friendly and is 100% recycle and durable.
