[PDF][PDF] Guidance for the identification of polymers in multilayer films used in food contact materials

A Mieth, E Hoekstra… - … JRC Technical reports, 2016 - iutdijon.u-bourgogne.fr
This guidance describes how to characterize the composition of a multilayer plastic film for
food packaging, with respect to the consecutive order of the layers and their identity. It
provides background information on the general composition of multilayer plastic packaging
and it illustrates in detail the separation of layers for some examples. It also provides in
annexes additional information related to the use of a microtome and of optical microscopy
using one common instrument for illustrative purposes.
