Heat Sealing Q&A
-
Asked March 9th, 2009
The answer depends upon the capabilities of the bar sealer that is currently being used. There are several parameters that must be controlled to ensure an optimum heat seal; temperature and pressure during the heating cycle, duration of the heating cycle, duration of the cooling cycle, or the temperature extent before the release of pressure. If these parameters can be controlled, the sealer can produce excellent seals on virtually any combination of sealable materials.
Coated Tyvek allows for a wider range of sealing parameters. When using uncoated material the time/temperature cycle must more closely controlled to ensure an acceptable peelable seal. Not all sealing machines are designed to ensure consistently repeatable control. When a Tyvek pouch is peeled open, the surface layer of the Tyvek delaminates if the seal has been properly made. If the seal has been overheated or over-pressured while sealing, the seal will become brittle and opaque, and the Tyvek layers will not separate properly.
