Finfoil offers coextruded barrier films for lamination in gauges between 22µm and 66µm.
These are co-extruded blown films, in our case 9 layers, with EVOH encapsulated between two layers of PA.
These films are frequently used in flexible packaging for foodstuffs and necessarily require lamination with other films.The final product is a multilayer that serves as a heat-sealed lid on trays or a film that, self-sealing, producesenvelopes with continuous sealing along the direction of flow of the packaging machine (e.g. flow-pack) and transversal sealing at point of packing.
The oxygen and water vapour barrier protects the food from natural oxidation and helps prolong shelf-life.
One side of the film is sealable, peelable or non-peelable, with anti-fog on request.
The quality of similar films can be seen above all in certain characteristics such as:
- mechanical properties
- antifog effectiveness
- sealing layer performance
