WARNING
Health hazard!
Insufficient or sporadic cleaning can promote the growth of micro-
organisms which can change unfavourably the product that is to be
packed.
This can severely damage the health of people, especially of the
consumers.
Among other measures the following are definitely required:
¾ Create a company cleaning guideline.
¾ Perform cleaning regularly.
¾ Check the effectiveness of cleaning procedures on a regular
basis.
¾ Follow instructions in the chapter 'Cleaning'.
1.7.11 Checking the packs
CAUTION
Health hazard!
Faulty or damaged packs (reject packs) can have far-reaching con-
sequences, for example, spoiled products.
Spoiled products can pose a health hazard.
¾ Check packs on a regular basis during running operation.
¾ Do NOT put faulty or damaged packs (reject packs) into circula-
tion.
Info
It is the operating company's duty to determine the overall testing
procedure.
Testing procedure
Depending on the film pouch and the demands placed on the packs,
various types of testing procedures are available, e.g.:
• Check seal seam width.
• Visual inspection: Asses the pack optically.
• Storage test: Store a good pack for a defined period and then re-
inspect.
• Stacking test: Stack good packs on top of each other for a defined
period and then re-inspect.
• Check the seal seam strength with a tensile testing machine.
• Low-pressure test (for vacuum packs).
• Measurement residual oxygen (for gas-flushed packs).
The following faults can result in a pack not being airtight:
• A leaky seal seam. Possible reasons:
– The inside of the packaging material is contaminated by product
in the seal seam area.
– The sealing time is too short.
