What are methods of tube sealing?

methods of tube sealing


Methods of Tube Sealing: Plastic, laminate, and metal tubes may all be sealed using different types of tube closing options. A hole punch for hanging tubes, curved seals, rounded corners, and customized seals for one-of-a-kind tube displays are just some of the options available for plastics and laminated squeeze tube sealing. 

Standard, smooth, and bespoke seal designs for plastics and laminated tubes are also available. Single, double, or triple fold and saddle fold for metal tube closures are available, as are smooth and wave crimp variations. You may choose between a plastic, laminate, or metal tube closure with a double-sided code that contains up to 12 digits.

A. Plastic and Laminated Tubes’ Sealing Methods

In ultrasonic sealing, a horn generates high-frequency friction to heat the tube seal. The tube seal is formed by clamping and cooling it against an anvil.

🔵 Hot Air Sealing

Hot air sealing heats the tube seal and transfers it to the closure station for pressing and chilling. Hot air tube sealing works on any plastics and laminated tubes and is the quickest way.

🔵 High-Frequency Sealing 

High-frequency sealing heats the tube’s aluminum and plastic layers. Clamp and cool the tube when it reaches the necessary temperature. However, for PE tubes, high-frequency tube sealing is not an option.
