LAYERED LAMINATES WITH OXYGEN-ABSORBING, WHITENING OR OXYGEN-ABSORBING AND WHITENING ADHESIVE LAYERS, METHODS OF THEIR PREPARATION AND APPLICATION

The invention relates to a method of making a layered laminate with an oxygen- absorbing adhesive layer, which consists in that in the first step the oxygen sorbent is introduced into the adhesive polyurethane system, to form an adhesive system absorbing oxygen, which is then applied to the surface of ribbon-bed layer and later dried, and in the second step a coating layer of thermoplastic material is applied on a layer of the adhesive system absorbing oxygen by a method of extrusion coating. The invention further provides a method of making a layered laminate with a whitening adhesive layer applied on it, and it also relates to an oxygen-absorbing layer laminate, bleached layered laminate, layered bleached laminate absorbing oxygen, and also to the use of the laminates for the manufacture of packaging in the food industry.
