Definitions

  • the object of the present invention is a bag for the containing of liquid products which emanate gas, in particular yeasts for bread making
  • yeast In the following description specific reference will be made to yeast, but it is to be understood that the invention can be applied to any liquid or paste product which during storage emanates gas.
  • Yeast in the phase of production, is always in the liquid state and, for the placing on the market, in the majority of cases, is subsequently dehydrated in order to transform it into powder or into the form of solid cakes. In the phase of use the yeast has once again to be returned to the liquid form.
  • the problem in the storage of the liquid yeast is that it emanates a considerable quantity of gas, in particular CO 2 , up to 1/3 litres a day for a package of 10/20 litres.
  • Bags are therefore necessary which on the one hand are highly permeable to the gases and on the other hand have adequate toughness for sustaining the weight of the content, these bags normally having a capacity of 10/20 litres.
  • double wall bags i.e. having a polyethylene-based inner film highly permeable to CO 2 , with very thin thickness (30-50 ⁇ m) and therefore with little mechanical strength, and an outer film constituted by a nylon-based laminate, with thickness of 80-150 ⁇ m, suitable for conferring the necessary mechanical strength to the bag.
  • the outer film which is not permeable, has a plurality of small holes to allow the release of the gases which permeate through the inner film.
  • the bag shaped in this way is placed inside a cardboard box in such a way as to constitute a so-called bag-in-box packaging which can easily be manipulated.
  • This pressure contact causes a strong adherence between the inner and outer plastic films of the bag, practically clogging the holes provided in the outer film and preventing therefore the release of the gases, which tend to accumulate in the upper part of the bag, where they have difficulty in exiting due to the small perforated surface of the outer film not in contact with the inner wall of the containing box.
  • the object of the invention is that of eliminating the aforesaid disadvantages of the prior art.
  • an object of the invention is that of providing a bag for liquid yeasts which allows a complete and rapid degassing of the product contained therein.
  • Another object of the present invention is that of providing such a bag which is simple and economical to manufacture.
  • the bag according to the invention has the features of the annexed independent claim 1 .
  • the bag according to the invention comprises a polyethylene-based inner film with high permeability and a reinforcing outer film, wherein the outer film is a nonwoven fabric of polyethylene-based fibres, so as to be sealable to the inner film.
  • the fibres of the nonwoven fabric of the outer film are constituted by a mixture of polypropylene and polyethylene (PP/PE), with a weight of 60-85 g/m 2 .
  • FIG. 1 is a schematic plan view of the bag according to the invention.
  • FIG. 2 is an enlarged section view taken along line II-II of FIG. 1 ;
  • FIG. 3 is a schematic perspective view of the bag of FIG. 1 .
  • the bag according to the invention for the containing of liquid products which emanate gas, in particular yeast, has been denoted by reference numeral 1 .
  • bag 1 has been illustrated rectangular in shape, which is the simplest to make, but it is clear that it can take on any other shape.
  • the bag 1 is of the so-called double wall type, in the sense that each of its two opposite faces 2 comprises two films, an inner one 5 and an outer one 6 , separated one from the other and joined only at said perimeter heat-sealing line 3 .
  • a spout 7 for filling/delivering of the product is applied, having a circular flange 8 sealed internally to the corresponding face 2 , while the spout 7 projects through a hole formed in this face, and is closed by a cap 9 .
  • the inner film 5 of the double wall of the bag is with high permeability to gases, in particular to CO 2 which is produced in a large quantity by the yeast contained in the bag, >50 l/m 2 day atm. It has a base of polyethylene, for example a coextruded LLDPE and has a very thin thickness (around 30 ⁇ m) and a weight of 28 g/m 2 in order to be able to obtain the aforesaid high values of permeability.
  • Such a film would alone be very fragile and therefore subject to easy tearing.
  • the outer film 6 is assigned the task of conferring toughness to the bag and avoiding easy breaking
  • This outer film 6 is a nonwoven fabric of fibres constituted by a PP/PE mixture of 60-185 g/m 2 .
  • the presence of polyethylene in the mixture constituting the fibres of the nonwoven fabric allows the performance of the perimeter heat sealing 3 to the inner film 5 , as well as the heat sealing of the base 8 of the spout 7 .
  • the manufacture of the outer film 6 in PP/PE nonwoven fabric allows the elimination of the disadvantages due to the adherence between the inner and outer films when the bag 1 is inserted in a containing box (bag-in-box) normally in cardboard.
  • the greater wrinkling of the nonwoven fabric according to the invention prevents the adherence between the films and allows easy release of the gas, in particular CO 2 , through the nonwoven fabric of the outer film 6 , which has micro holes over the entire surface.
