Abstract
The present invention provides a recyclable laminate film structure comprising a separation layer coating. The separation layer coating facilitates separation of a selected polymer film during the recycling processing by selecting the polymer of the coating composition to have particular Hansen Solubility Parameters, so that the laminate structure delaminates at the layer of the coating, leaving clean pieces of the selected polymer film. In certain embodiments, the separation layer coating is a barrier coating, such as an oxygen barrier coating.
