<p>A method of treating a packaging laminate (10) with a view to increasing its friction, the packaging laminate having an outer coating (12) of thermoplastic, for example high density polyethylene. The packaging laminate (10) is heated on its thermoplastic-coated side to commenced melting of the outer coating (12), whereafter the packaging laminate is cooled in order once again to solidify the thermoplastic coating thus heated to commenced melting. Preferably, the packaging laminate is heated by so-called flame treating.</p> |
