Abstract
A binder for a packaging laminate, which binder comprises a polyolefin grafted with an unsaturated alkoxysilane. According to the invention, the grafted polyolefin is blended with a non-grafted polyolefin, in said binder, whereby the flexibility of the binder is improved, which in turn provides for an increased number of adhesion points when the binder is used in a binding layer in the packaging laminate. The invention also relates to packaging laminate (10, 30, 40, 50) comprising the binder and to a packaging container (60) formed form the packaging laminate.
