Smart Houseware Vaccum Flasks Highlight Your Brand

Make the most of Smart Houseware’s manufacturing capabilities to produce tough vacuum flasks. We use trusted food-grade materials approved by SGS. From plastics to metals, our flasks are durable and safe for use.

We create vacuum flasks through strong suction by vacuum machines that increase the space inside the bottles. The double wall vacuum insulation we use in the vacuum flasks that controls the temperature inside and ensures that any liquids placed inside will take longer to freeze. As a result, the contents in the flask will remain in their liquid or warm states.

Enjoy modern designs that attract your market to your brand. Their shape makes our flasks excellent hydration bottles for the gym. For further assurances, you can ask for a full inspection.
