WRAPPING
1. Simple packaging, with or without the use of a machine 2. Packaging on a bagging machine Over-wrapping only (Flowpack) In a modified atmosphere (BDF) Possibly with shrink film
Using stretch or shrink film
Simple process
Short Shelf Life
Over-packaging
No vacuum, no gas!
Flushing of bagging gas
It is not possible to create a vacuum on a bagging system or Flowpack machine.If we want to replace the air present in the packaging, to change the composition and reduce the residual amount of oxygen before sealing, we must instead use the gas flushing technique.
