We use flexible film packaging which we received flat and printed. It is formed then formed in to bags before filling. In BRC, Clause 4.13 of product Analysis, quote: " a company is required to undertake analyses...." is it mandatory to perform SML test on the packaging used or can Supplier recommendation be used. And if analyses have to be performed, who/where/to whom do i turn to?
Yes indeed, Migration Testing and limits for OPP packaging.
I had an interesting conversation last week on this very subject with a Group Quality Manager for a very large UK dairy.
We both agreed that it was the manufacturer of the packaging that was responsible for ensuring that the material met all legal requirements (including SML) for food contact packaging. What we could not agree on was how often this migration testing should be carried out by the supplier.
The packaging manufacturer may say they carry out the migration testing once when the packaging / food contact coating is first developed and is only carried out again if there is a change to the specification or if the law changes. The end customer e.g. a big retailer may require migration testing to be carried out annually; auditors from retailers like to specify 'annually' as it’s a nice neat frequency for all sorts of testing / reviews etc.
I would side with the packaging manufacturer. Imagine a food packaging film with a heat seal coating that was developed 10 years ago. It met all of the migration limits then and was approved for use with food. So if nothing changes to the specification why the need to test again. 10 years may seem like a long time. But if we just want a shorter testing frequency because 10 years doesn’t seem right. Why not carry out migration testing of every batch?
Our conclusion was we were not sure of the frequency, but if the big retailer auditor wanted annually we would have the debate and then do it. :)
In answer to your question Charmeen; your packaging supplier must provide you with the certificates and migration test results for the material they supply to you. And the packaging material and supporting documents must be able to meet the migration limits laid own in the relevant legislation of the country(s) you supply your products to.
Hope this helps.
