Refer to the sub-section on “Inert gas” in the next section, “Processing materials”, for further important
information on the types of inert gas which may be used.
2.1.2 Processing materials
2.1.2.1 Vacuum bags
The vacuum bags must be suitable and passed for welding under pressure and heat. They must also
conform to hygiene regulations in terms of the handling and packaging of foodstuffs. Obtain a certificate
of suitability from the manufacturer. The vacuum bags must also display the following properties:
§ resistance to refrigeration
§ resistance to heat
§ strength
The machine owner is responsible for ensuring that the vacuum bags used are suitable for heat welding
and do not pose any potential dangers, such as fire hazards or the emission of toxic substances.
2.1.2.2 Suitable products
The products which are suitable for vacuum processing are those which neither explode nor emit toxic
gases during this process or which are not damaged as a result of the effect of the vacuum.
IMPORTANT
The products being packaged may not possess any sharp parts which may penetrate through
the packaging over time and damage the hermetic seal of the packaging.
If you are in any doubt, check the suitability of the products using spare samples or contact the
manufacturer of the machine for advice.
DANGER
Generating vacuums kills live animals! Do not vacuum pack anything which is alive and ensure
that no live animals are vacuum packed by unauthorised personnel or children!
DANGER
Inflammable, potentially explosive substances and pressurised gas cylinders may not be
packaged becaus e they may endanger the health and well-being of the operator!
