    摘要： The invention relates to multi-layered, sack-type packaging (1), configured from a respective broad front face (3) and rear face (2), which are connected by narrow lateral faces (4) and (5), said packaging being sealed at the upper end (6) and the lower end (7) with part of the upper end (6) remaining open (8) for filling. Said packaging comprises an inner wall (9) consisting of an air-permeable material, said wall being surrounded by an outer wall (10) consisting of an airtight material. Said packaging is characterised in that: a) on the front (3) and/or rear face (2), the outer wall (10) has an overlapping sub-section (11) extending over up to 50 % of the total surface area; b) in said overlapping section (11), the inner layer (10a) of the outer wall (10) is perforated; c) the two overlapping layers (10a und 10b) are connected by seams (14 and 15) at the edges (12 and 13) of the overlapping section (11); and d) on one or both edges (12 and 13) the connection is interrupted in an area (16) covering between 10 and 50 % of the total length.

    摘要： The invention relates to polyvinyl acetals containing unsaturated acetal units that can be obtained by the acetalisation of partially or fully saponified vinyl ester polymers containing > 50 mol. % of vinyl alcohol units comprising at least one saturated aliphatic aldehyde and at least one unsaturated, acyclic, aliphatic aldehyde. The aldehydes can also be added in the form of the semi-acetals and full acetals thereof.
