The adhesive is particularly suitable for packages for consumer products that provide sufficient strength and thermal insulation while reducing the overall basis weight of the substrates.

Hence the mass per unit area thereof remains of the order of 15 g/dm2.

The tearable front ear has a basis weight less than a basis weight of the back ear.

Transparency = degree of white (%)/basis weight (g/m2) when the water content per sheet mass has been set at 700 mass%.

The breathable microporous film has a basis weight of 30 g/m2 or above.

The weight per unit area of the glass fiber mat is between 25 g/m2 and 80 g/m2.

The fibrous web layer can have a basis weight of at least about 60 gsm, and a density of not more than about 0.25 gm/cc.

In a variant, the non-woven fabric (4,5,6,7,8) has a weight gradient area at least 2.5 times less than the weight gradient area of the textile outer layer.

In fact the mass per unit area is preferably within a range of 0.15 and 0.35 g/m2.

The mounting mat includes a layer or sheet of inorganic fibers with a portion of the layer having a first basis weight and another portion having a second basis weight that is different from the first basis weight.

Chopped fiber mats with uniform surface mass generally ranging between 50 and 1100 g/m2 are obtained.

The ratio of the first web basis weight to the second web basis weight may range from 30/70 to 70/30.

Can be considered as indivisibly associated; and
