<p>The invention is directed to a laminate suitable for forming into a pouch (40) for pumpable products, the laminate including a thermoplastic packaging film, and a patch (42) adhered to the packaging film, the patch (42) including a thermoplastic material and characterized by an elongation at break, at 73 DEG F (23 DEG C) (ASTM D 882) of at least about 700% in each of the machine and transverse directions. The invention in another aspect is directed to a pouch (40) comprising a pumpable product; a thermoplastic packaging film containing the pumpable product; and a patch (42) adhered to the thermoplastic packaging film, the patch comprising a thermoplastic material and characterized by an elongation at break, at 73 DEG F (23 DEG C) (ASTM D 882) of at least about 700% in each of the machine and transverse directions. The patch reduces leakage when pierced by a dispensing spout.</p> |
