  • Patent number: 9392817
    Abstract: The invention relates to a paper that disintegrates quickly in water, for use as a filter material or filter wrapper paper of a cigarette filter. At least 80 wt % of the paper is formed by cellulose fibers. Of the cellulose fibers, at least 80 wt % are a mixture of long fiber pulp and mercerized pulp. 0 to 90 wt % of the content of the mixture is formed by mercerized pulp, and the rest is formed by long fiber pulp. The cellulose fibers of the mixture have a freeness of at most 30° SR according to ISO 5267. In the disintegration test using an apparatus as described in TAPPI T 261, the paper exhibits a disintegration of at least 60% after 30 seconds.

  • Patent number: 9333933
    Abstract: The invention relates to an airbag package (1) for an occupant restraint system of an automotive vehicle comprising a folded airbag (2) and clearances formed between the material of the airbag, wherein the airbag package (1) has a real package volume Vreal composed of the airbag volume VSack of the airbag (2) and the clearance volume Vfrei of the clearances. The invention excels by the fact that the ratio Vreal/VSack between the package volume Vreal and the airbag volume VSack is at most 3.2. The invention further relates to an occupant restraint system comprising such airbag package and to a method of manufacturing an airbag package.

  • Publication number: 20160120214
    Abstract: A cigarette paper is disclosed that contains at least one burn additive the concentration c(x) of which varies along a direction x of the cigarette paper. For the position-dependent concentration c(x) over an interval of length L, for x over the interval [0,L], f(x)??c?c(x)?f(x)+?c. In this regard, 3 cm?L?11 cm, f(x) is monotonic over the interval [0,L], but not a constant function over the entire interval, and ?c?1% by weight, preferably ?0.7% by weight and particularly preferably ?0.5% by weight, and especially preferably ?0.3% by weight and particularly preferably ?0.15% by weight and ?c>0% by weight, each with respect to the mass of the cigarette paper.
