Heat sealer used to prepare plastic bag of lettuce for shelf life testing Continuous band heat sealer. A heat sealer is a machine used to seal products, packaging, and other thermoplastic materials using heat. This can be with uniform ...
A welded seam or insertion tube sealing process creates seals that can withstand various types of requirements for certain liquid types or air pressures. An example of this would be for the medical industry, where ensuring the seal is airtight and fluid-tight is crucial. [7] An IV drip bag, showing a RF weld around the perimeter.
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
A tube, squeeze tube, or collapsible tube is a collapsible package which can be used for viscous liquids such as toothpaste, artist's paint, adhesive, caulk, & ointments. Basically, a tube is a cylindrical , hollow piece with a round or oval profile, made of plastic , paperboard , aluminum , or other metal.
Sealing containers, tubes and blister packs are common applications. Ultrasonic welding is also applied in the packaging of dangerous materials, such as explosives, fireworks and other reactive chemicals. These items tend to require hermetic sealing, but cannot be subjected to high temperatures. [9] One example is a butane lighter.
This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics.
Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads. The tape is sold cut to specific widths ...
The typical machine is loaded with a continuous flat roll of plastic film, which has usually had labeling and artwork applied. Plastic is the most commonly used packaging material in the food industry, but the technology can be used to form continuous metallized foil/film, paper, and fabric product containers by changing the edge sealing/seaming methods.
