Cellulosic web with a permeant barrier or contaminant trap

The invention claims a containing plate and corrugated paper board are in a manufactured by a cellulose bottom fibre piece, wherein when the transudate or the impurity exist with the obstructing collecting performance improved; the sheet comprising: (a) comprises any direction cellulose fibre is a layer structure of serial device, comprising a product side and outer; (b) of the product side, comprising a efficient are connected dextrin chemical composite and diluent barrier, wherein the diluent comprises a starches, the modified starches, alpha celluloses, the modified alpha celluloses or the cavity; mixturesA (c) on the outside, comprising a clay and printing layer or is used for usual the packing layer; The is characterised of; the ring dextrin chemical composite said without matched with the chemical composite comprising A Box, and a serve as a coming from the environmental transudate through the barrier or serves as the impurity remover is a sheet production. The circular dextrin sand of comprises a thermoplastic film, the film of brake and comprises a alpha cellulose piece (240) double-layer or a multi-layer laminated.
