Sheet-like composite, especially for containers, having an adhesion promoting layer characterized by different C = O-based absorption maxima

摘要

In the present invention, as a layer constituting the layer arrangement, (a) an outer polymer layer, (b) a support layer following the outer polymer layer, (c) a barrier layer following the support layer, (d) an adhesion promoting layer following the barrier layer And (e) an inner polymer layer following the adhesion promoting layer, the adhesion promoting layer having an outer surface of the adhesion promoting layer and an inner surface of the adhesion promoting layer, wherein the outer surface of the adhesion promoting layer comprises (i) the barrier And (ii) characterized by a first C═O group absorption maximum, the inner surface of the adhesion promoting layer is (A) adjacent to the inner polymer layer, and (B) a second C═O group. Characterized by an absorption maximum and (C) having a first distance to the outer surface of the adhesion promoting layer, the first C═O group absorption maximum being greater than the second C═O group absorption maximum The present invention also relates to a sheet-like composite that is large. Furthermore, the present invention provides a method for producing a sheet-like composite, a sheet-like composite obtained by the production method, a container precursor, a method for producing a container precursor, and a container precursor, a container, and a container obtained by the production method. The present invention relates to a method, a container obtained by the production method, use of a sheet-like composite, and use of a container. [Selection] Figure 1
