Abstract

The disclosure relates to liquid-tight packaging laminates with improved mechanical strength and flexibility, with an outer layer of a mixture of metallocene polyethylene and low density polyethylene (LDPE), and mechanically strong liquid-tight packaging containers produced from the packaging laminate. The packaging laminate also has improved friction properties and improved resistance to stress-cracking as a result of fat- or fatty acid-containing substances. The packaging laminate is produced in a simple, rational manner using existing processing and production machinery. A packaging laminate according to the invention (60) includes a core layer (61) of paper and at least one outer layer (66) including a mixture of metallocene-polyethylene and suitably at least approximately 10 % by weight, preferably approximately 10-50 % by weight, more preferably approximately 20-40 % by weight, and most preferably approximately 20-30 % by weight of LDPE. The packaging laminate may also include additional gas barrier layer (63) and adhesion layer (64; 65). The outer layer (66) is applied by extrusion coating or co-extrusion, and, thanks to its superior processing properties, can be applied by means of existing processing machinery at hight line speeds.
