Abstract (en)
[origin: WO9814317A1] A groove (16) is provided through a covering (12, 13) forming part of a laminate (11) and extending over a polymer layer (15) of the laminate (11). By way of the groove (16), a limited zone (15A) of the polymer layer (15) substantially aligned with the groove (16) is heated to a temperature such that, following cooling of the zone (15A), the zone is more readily breakable. The covering (12, 13) mitigates the effect of the heat H on other zones of the polymer layer (15).
