When we think of collapsible tubes we most likely think of toothpaste since we all use it every day. Tubes are also used for packaging many other products such as foods, pharmaceuticals, cosmetics, candy and more. Tubes can be used for any liquid from very thick like silicone caulk to as thin as water. Occasionally tubes are even filled with powder. Tube filling/sealing speeds run from 20-30ppm to 500+ppm.
