Sealing with Air-Assist
All machines are equipped with regulators for air-assisted sealing. Set the air pressure
regulator to 20 p.s.i. increasing to a maximum of 40 p.s.i. While a good seal can be
obtained without air-assist, use air-assist when:
• Gas back-flushing above average pressure.
• Using shrink pouches.
• Packaging a product that easily contaminates the seal area of the pouch.
• Trying to overlap pouches.
• Wrinkles cannot be avoided in the seal area.
• Using the Double Seam Seal option.
• Always use air-assist when using the Perforating Knife Option.
• Always use air-assist when using the Precut Option.
• Always use air-assist when using the 10mm Wide Seal Band Option
Gas Flush Option
Gas flushing is the introduction of an inert gas into the chamber after the vacuum stage
is finished. Gas can be used as a filler to prevent crushing of the product after sealing, as
a means to prolong shelf life, or as a means to maintain desirable product appearance.
Commonly used gasses include nitrogen, carbon dioxide, or a mixture of both. Consult your
local gas supplier to select the proper gas for your product.
WARNING WARNING
Explosion hazard.
Do not use a gas with an oxygen content greater than 22% with gas flush option.
Double Seam Seal Option
All machines are equipped with standard seal bars having a single seal element per
seal bar. The Double Seam seal bars have two seal elements per seal bar. We strongly
recommend using air-assisted sealing with this option to achieve best results.
10mm Wide Seam Seal Option
All machines are equipped with standard seal bars having a single seal element per
seal bar. The 10mm Wide Seam seal bars have a wide seal element. It is required to use
air-assisted sealing with this option to achieve best results.
