1. What is a vacuum bottle?
A vacuum bottle is a special type of packaging bottle designed to completely isolate its contents from air, thereby avoiding oxidation, deterioration, and bacterial growth, and maintaining the activity of the raw materials.
2. Structure of vacuum bottle
A vacuum bottle is mainly composed of a cylindrical container and a piston placed at the bottom. Its design principle is to use the contraction force of the spring to create a vacuum state inside, thereby pushing the bottom piston of the bottle forward through air pressure.
3. Material of vacuum bottle
Vacuum bottles are usually composed of multiple materials, including the following:
Highly transparent materials (such as PMMA, AS, PET)
Translucent materials (such as PP, silicone, LDPE, LLDPE)
Solid color materials (such as ABS, HDPE, rubber, etc.)
