Hi, does anyone have a copy of the latest Marks & Spencer's standard or criteria. We have just had an interesting conversation with a rep from a company that sells metal detection and x-ray machines who tells me that M&S will permit up to a 1.5mm piece of metal or other contaminent in their packaging products.
As we get black bits as a matter of course in recycled PET as a result of the post consumer waste we usually reject larger ones due to aesthetic nature.
I was wondering if anyone had a copy of the M&S standards or criteria for this that they could share with me please?
I am not familiar with the PET recycling process / limitations however i interpret the above as that the rep is stating that, for yr specific matrix, "their" equipment will detect (unspecified) "metal" if >=1.5mm.
This may well be some kind of reasonable statement of unavoidable machine fact.
However any (hopeful?) parallel criterion that smaller but, apparently clearly visible, particles are "aesthetically" acceptable will surely also relate to absolute frequencies of occurrence, eg qualitatively speaking - rare or often. Plus the intended application. ?
Offhand, sounds more like a rep's "pitch" although there may be "some" acceptance reality within it since presumably M&S are also familiar with MDts.
