  • TRANSPARENT, GAS-PERMEABLE AND WATERPROOF FILM, PARTICULARLY FOR APPLICATIONS IN THE MEDICAL FIELD
    Publication number: 20240139690
    Abstract: A transparent, gas-permeable and waterproof film, particularly for applications in the medical field is disclosed. The film includes a polyolefin base, to which is added a monomeric plasticiser with a percentage by mass of between 10% and 50% and preferably also molecular sieves with a percentage by mass of less than or equal to 20%, this addition enables in particular the gas permeability of the film to be increased, said film thus having a high gas permeability, as well as low water permeability and high transparency, together with various mechanical characteristics and properties so that it is particularly well suited to many applications, in particular in the medical sector and in particular for application to an identification card used in the medical diagnosis.

  • Support covered with a chitosan-based coating and method for the production thereof
    Patent number: 7241498
    Abstract: Support based on organic and/or inorganic fibres covered at least on one of the faces thereof with a chitosan-based layer, characterized in that the layer is obtained by depositing a chitosan-based aqueous solution, the average molar mass of which has a mass less then 130 000 g/mol, the concentration of which is between 6 and 30% by weight and the viscosity of which is between 100 and 3000 cps.

  • Use of material based on organic and/or inorganic fibres and chitosan for fixing metal ions
    Patent number: 7189326
    Abstract: The invention concerns the use of a material based on organic and/or inorganic fibres and chitosan for fixing metal ions contained in an effluent. The invention is characterised in that chitosan represents between 0.01 and 20% by dry weight of fibres and its degree of deacetylation is higher than 90%.
