Abstract (en)
[origin: WO2008056035A1] This invention relates to a group package (1) for sheet material such as printing and photocopy paper, and a method for manufacturing the protective wrap of the group package and the group package itself. In the group package (1), a number of paper bundles (Ia) wrapped in their own ream wraps (2a) consisting of at least a base paper layer (19a), are placed within a shared protective wrap (2). The material of the protective wrap (2) and of the wrap (2a) of the paper bundles (Ia) is formed by adding plastic, a polymer mixture or another suitable material to one or both of the materials, in suitable quantities to make the combined water vapour transmission rate (WVTR) of the protective wrap (2) and the wrap (2a) less than approx. 50 g/m2/d, as calculated according to the ISO 2528:1995 standard.
