by the action of the tractive force which is applied on the opening strip or tab 6 when this is pulled off a further requirement for ensuring a complete exposure of the hole 2 when the opening strip or pull tab 6 is pulled off is that the internal sealing strength between the two layers 4 a and 4 b must also be sufficiently strong to prevent the second outer layer 4 from delaminating the illustrated packaging laminate 10 in fig1 can according to the present invention be produced in the manner that is schematically illustrated in fig2 and which effectively ensures that all conditions and preconditions for the intended opening function of the pull tab or opening strip 6 be satisfied from a magazine 1 u2032 to the left in the figure a web 1 of paper or paperboard of suitable packaging quality is unwound the unwound web 1 is led in the direction of the illustrated arrow to a first processing station at 7 where the web in a conventional method and using previously known means is provided with through going holes 2 fig1 by a punching operation since neither the method nor the equipment for providing the web 1 with these holes constitutes any germane part of the present invention they will not be described in greater detail in this context the holed web 1 is thereafter led further to a first coating station at 8 where the web is led through the nip between two rollers 8 a and 8 b rotating in the direction of transport of the web at the same time as the one side of the web 1 is coated with a first outer layer 3.
