Definitions

  • the present invention relates to a flexible sheet which can be used especially for sterilizable packaging.
  • a first property is that the sheet must be flexible to ability to form sachets into which objects of various shapes and sizes.
  • a second property is that the sheet must be resistant to tearing as well as bursting. Indeed, it is intended for contain objects which may be heavy and blunt or sharp. In addition, it is intended in the form of a sachet, during sterilization with gases, for example ethylene oxide, to be subjected to pressure during gas injection and strong posterior depression during the evacuation of gases, which must be complete.
  • gases for example ethylene oxide
  • a third property is that the sheet must be slightly absorbent especially with regard to water, so that water or other products liquids do not penetrate through the sachet formed by the sheet, from outside to inside, by defiling the wrapped object, in the bag.
  • Such sheets of paper are sold to manufacturers of sterilizable sachets or packaging that make up the sachet having a layer of lacquer which ensures the connection between the edges of the sheet and a transparent film.
  • processors apply heat-sealable lacquer, aqueous or solvent medium, so as to preserve a certain gas permeability of paper.
  • the bags or pouches are then heat-sealed with plastic films.
  • Sheets have also been made of the dry non-woven type, that is to say that a mattress of synthetic fibers, for example polyethylene, is made, which is bonded together, when hot. These sheets are manufactured by the company DU PONT DE NEMOURS and sold under the name of TYVEK R. These sheets are resistant to tearing and bursting. In addition, they are flexible. However, a major drawback of these sheets is that their thickness is very heterogeneous, that is to say that the distribution of the fibers per unit area is irregular, which means that the porosity of the sheet is not uniform. Thus, in certain places, the sheet will have pores of too large diameter, which will have the effect that the microorganisms will be able to penetrate inside the packaging produced using this sheet. On the contrary, in certain places, the sheet will have pores of too small diameter, which will hinder the penetration of the molecules of sterilizing gas. In addition, these sheets are absolutely permanent, that is to say non-biodegradable.
  • the invention is remarkable in that, according to a person skilled in the art, it it is difficult to combine the requisite qualities simultaneously. Indeed, the products that improve mechanical characteristics increase the rigidity, therefore decrease flexibility.
  • the first fabric softeners mentioned destroy connections interfibers, so they decrease the mechanical characteristics.
  • the second cited do not have this disadvantage but they oppose the action of the bonding agents which give the barrier properties leaf.
  • the invention relates to a flexible sheet, resistant to tearing and bursting, very little absorbent with water or other liquid, with controlled porosity, printable, comprising a support based on cellulose fibers of which at least one of the faces is impregnated with a composition comprising at least one binder, characterized in that the composition contains at least one moisture-retaining agent and at least one bonding agent, such as the measured COBB 60 bonding according to ISO535 standard, is less than 20 g / m 2 , that the TABER stiffness, measured according to ISO 2493 standard is less than 2.5 and that the amount of moisture-retaining agent is less than about 20% by weight dry leaf.
  • the sheet preferably contains at least 1% moisture-retaining agent.
  • the humidity-retaining agent is preferably chosen from the group formed by urea, a nitrate salt or their mixtures.
  • urea-nitrate mixture the mixture can preferably be used in a urea / sodium nitrate ratio of 2: 1.
  • the bonding agent is chosen from the group formed by wax or paraffin dispersions, alkyl ketene dimers, alkylene succinic anhydrides, stearic anhydrides and their mixtures.
  • the binder is chosen from the group formed by polyvinyl alcohol, native starch or its derivatives, cellulose ethers or esters, alginates, guaranates or mixtures thereof.
  • the impregnation composition is preferably carried out in the medium aqueous.
  • the fibrous support is preferably a support formed mainly cellulose fibers.
  • This support is preferably not bonded en masse; it can contain at least one wet resistance.
  • the sheet is produced by a papermaking process.
  • the support can be impregnated with the composition according to the invention, using a sizing press. Any other means of impregnation or bedding usually used in stationery may be suitable.
  • the invention makes it possible to provide printable sheets, preferably by heliographic printing, offset or flexographic.
  • the invention makes it possible to provide sheets whose physical characteristics are homogeneous, i.e. substantially the same in the cross direction as in the running direction.
  • the invention makes it possible to provide sheets which are the more easily biodegradable after use and the cost of manufacturing is competitive.
  • the invention is remarkable in that a sheet is obtained having a COBB of less than 20 g / m2 and up to 12 g / m2, and having a TABER stiffness of less than 2.5 and having an index of tear greater than 80 cNm2 / g.
  • the following examples are carried out on a paper machine of laboratory. We impregnate, using a sizing press, a support based on cellulose fibers, not mass bonded. The compositions for the impregnation bath are carried out in medium aqueous.
  • the tear index is measured according to ISO standard 1974.
  • the dry burst index is measured according to the ISO 2758 measurement.
  • the wet burst index is measured according to ISO standard 3686 (after immersion in water for ten minutes). (after immersion in water for ten minutes). Burst REH (wet strength) is the ratio of the wet burst and dry burst indices, multiplied by 100.
  • TABER stiffness is measured according to ISO 2493.
  • BENDTSEN porosity is measured according to ISO 5636/3.
  • the dry recovery expresses the quantity of sauce by dry weight absorbed per sheet per square meter.
  • the sheets obtained are sterilizable. They are sealable and peelable.
