Definitions

  • the invention relates to a new absorbent pad for use in the packaging of food products, to the process for the manufacture thereof, to its use in the manufacture of food packages and to the packages thus obtainable.
  • absorbent pads have been proposed which comprise a mat of an absorbent material enclosed between two sheets of plastic material, which are sealed along their edges.
  • US Patent 5,055,332 and US Patent 6,270,873 both disclose absorbent pads for food products including an upper and lower plastic film, at least one of which is perforated, and an intermediate absorbent layer.
  • these types of absorbent pads have some disadvantages. The absorbed liquid is visible through the plastic sheet of the pad partly due to the perforations and, unless it is glued to the bottom of the container, the pad tends to stick to the packaged product creating a negative impression on the consumer who has to manually remove it.
  • FR-A-2,687,381 discloses a mat of absorbent material held in place at the bottom of a packaging container by means of a film of plastic material glued to the bottom of the container, the film being preferably perforated. All these types of pad are sometimes difficult to handle in automatic padding operations, their excessive flexibility making it difficult to correctly position the pad in a container, such as a tray or a bag.
  • DE 90 13 898.8U discloses an absorbent pad, covering only part of the bottom of the tray, comprising two plies, one of an absorbent material and the other of a water-impermeable support, made of a material chosen from the group of PE, PP or PS which is preferably foamed and with a thickness comprised from 120 to 300 ⁇ m.
  • the water-impermeable support covers completely the absorbent material hiding the absorbed liquid from the sight of the consumer.
  • the support and the absorbent layer are sealed or glued to each other and to the bottom of the tray to avoid any displacement.
  • this solution has two main drawbacks.
  • EP-A-609,184 discloses an absorbent pad comprising two plies, i.e, a layer of an absorbent material laid on the bottom of a tray separated from the product by a support, said pad forming with the sides of the tray a drain encircling the pad. Said pad can be either glued to the bottom of the tray or it can be secured by a series of clips protruding from the sides of the tray.
  • FR-A-2,749,567 discloses a tray having an internal ledge which is profiled to present an overhang projecting over the base of the tray to form a structure which grips and centres a pad of absorbent material on the base of the tray.
  • the above-mentioned solutions involve the use of special moulds for producing a tray with suitable clips requiring additional expenses in the manufacturing of the tray.
  • a first objective of the present invention is therefore to provide an absorbent pad that may efficiently absorb and hide from the sight of the consumer any type of liquid present in a food package.
  • Another objective is to provide a pad that can be conveniently handled and positioned during packaging operations.
  • Still another objective of the invention is to provide a pad that can be reliably secured to a container without requiring special moulding tools for the preparation of the container, thus avoiding the risk of removing the pad together with the product.
  • a first object of the present invention is a rigid or semi-rigid absorbent pad comprising a rigid or semi-rigid support made of a liquid impermeable material having two flat opposing surfaces, and a mat of liquid absorbent material laminated over only one of the surfaces of the rigid or semi-rigid support, characterized in that,
  • a second object of the present invention is a process for the manufacture of a pad according to a preferred embodiment of the present invention.
  • a third object of the present invention is a composite web for the production of an absorbent pad according to the present invention, said composite web being wound into a roll.
  • a further object of the present invention is a food package comprising an absorbent pad according to the present invention and a container.
  • an absorbent pad comprising a rigid or semi-rigid support made of a liquid impermeable material having two flat opposing surfaces, and a mat of liquid absorbent material laminated over only one of the surfaces of the rigid or semi-rigid support, characterized in that,
  • the phrase "rigid or semi-rigid” refers to a material that does not deform, bend or loose its shape when deprived of support.
  • the rigid or semi-rigid support of liquid impermeable material employed for the pad of the present invention is made of one or more layers of a thermoplastic material chosen from the group comprising polyolefins, polyesters, polystyrenes, PVC, poly(lactic acid) and the like materials.
  • Suitable polyolefins include ethylene homo- and co-polymers and propylene homo- and co-polymers.
  • copolymer refers to a polymer derived from two or more types of monomers, and includes terpolymers.
  • Ethylene homopolymers include high density polyethylene (HDPE) and low density polyethylene (LDPE).
  • Ethylene copolymers include ethylene/alpha-olefin copolymers and ethylene/unsaturated ester copolymers.
  • Ethylene/alpha-olefin copolymers generally include copolymers of ethylene and one or more comonomers selected from C 3 to C 20 alpha-olefins, such as 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene and the like.
  • Ethylene/alpha-olefin copolymers generally have a density in the range of from about 0.86 to about 0.94 g/cc.
  • the term linear low density polyethylene (LLDPE) is generally understood to include that group of ethylene/alpha-olefin copolymers which fall into the density range of about 0.915 to about 0.94 g/cc and particularly about 0.915 to about 0.925 g/cc.
  • LLDPE linear medium density polyethylene
  • Lower density ethylene/alpha-olefin copolymers may be referred to as very low density polyethylene (VLDPE) and ultra-low density polyethylene (ULDPE).
  • Ethylene/alfa-olefin copolymers may be obtained by either heterogeneous or homogeneous polymerization processes.
  • Heterogeneous processes afford products with relatively wide molecular weight distribution (M w /M n greater than 3.0) and composition distribution.
  • Heterogeneous copolymers typically contain a relatively wide variety of main chain lengths and comonomer percentages.
  • homogeneous processes afford products with relatively narrow molecular weight distribution (M w /M n less than 3.0) and composition distribution.
  • Homogeneous polymers are structurally different from heterogeneous polymers, in that homogeneous polymers exhibit a relatively even sequencing of comonomers within a chain, a mirroring of sequence distribution in all chains, and a similarity of length of all chains.
  • Heterogeneous polymers may be prepared, for instance, with Ziegler-Natta catalysts.
  • homogeneous polymers are typically prepared using metallocene or other single-site catalysts.
  • ethylene/unsaturated ester copolymer is the copolymer of ethylene and one or more unsaturated ester monomers.
  • Useful unsaturated esters include vinyl esters of aliphatic carboxylic acids, where the esters have from 4 to 12 carbon atoms, such as vinyl acetate, and alkyl esters of acrylic or methacrylic acid, where the esters have from 4 to 12 carbon atoms.
  • Useful propylene copolymers include propylene/ethylene copolymers (EPC), which are copolymers of propylene and ethylene having a majority weight percent content of propylene, and propylene/ethylene/butene terpolymers (EPB), which are copolymers of propylene, ethylene and 1-butene.
  • EPC propylene/ethylene copolymers
  • EPB propylene/ethylene/butene terpolymers
  • polyesters refers to polymers obtained by the polycondensation reaction of dicarboxylic acids with dihydroxy alcohols.
  • Suitable dicarboxylic acids are, for instance, terephtalic acid, isophtalic acid, 2,6-naphthalene dicarboxylic acid and the like.
  • Suitable dihydroxy alcohols are for instance ethylene glycol, diethylene glycol, 1,4-butanediol, 1,4-cyclohexanedimethanol and the like.
  • useful polyesters include poly(ethylene 2,6-naphtalate), poly(ethylene terephtalate), and copolyesters obtained by reacting one or more dicarboxylic acids with one or more dihydroxy alcohols.
  • polystyrenes refers to homo- and co-polymers of styrene.
  • Useful styrene copolymers include styrene/butadiene rubbers (SBR), styrene/butadiene block copolymers (SBS), styrene/ethylene/butadiene copolymers (SEBS), styrene/isoprene block copolymers (SIS) and the like.
  • the rigid or semi-rigid support of the liquid impermeable material has a thickness comprised between 100 microns to 5 mm, preferably from 200 microns to 4 mm, and even more preferably from more than 250 microns to 3 mm.
  • Thicknesses lower than 100 microns e.g. down to 50, 60, 70, 80, 90 microns, may also be employed, depending on the modulus of the particular resins used, but in most cases they would not offer a sufficient rigidity for a reliable handling and positioning of the pad in automatic padding operations. Thicknesses higher than 5 mm would make the cost of the pad excessive without providing beneficial effects.
  • the rigid or semi-rigid support of the pad is an extruded monolayer material.
  • the support is foamed or contains inorganic fillers, such as talc, TiO 2 , calcium carbonate and the like, so to be rendered opaque, therefore hiding the absorbed liquid from the sight of the consumer.
  • the rigid or semi-rigid support of the pad consists of at least two layers: an upper layer, which is in contact with the product in the final package, that confers rigidity to the support and a lower layer, which is bound to the mat of liquid absorbent material.
  • the upper layer is thicker than the lower layer, the ratio of the two thicknesses depending on the modulus of the plastic materials employed.
  • the upper layer of the support is foamed or contains inorganic fillers, such as talc, TiO 2 and the like. Even more preferably, the upper layer of the support is made of the same material as the container with which it forms the final package, therefore not only hiding the absorbed liquid but also being indistinguishable from the container at first sight.
  • the lower layer is made of a material chosen from the group of polyolefins, suitable for binding with the mat of liquid absorbent material.
  • Preferred materials are copolymers of ethylene and unsaturated esters, such esters of aliphatic carboxylic acids and alkyl esters of acrylic or methacrylic acid, more preferably vinyl acetate.
  • Other layers can be present between said upper and lower layers. For instance a tie layer might be employed to improve the adhesion between the upper and the lower layer or additional layers might be employed to modulate the mechanical properties of the whole support.
  • the support can be produced either by extrusion, co-extrusion or by heat- or glue-lamination.
  • Non-limiting examples of suitable supports for the pad of the present invention, particularly in conjunction with foamed polystyrene trays, are laminates of a foamed polystyrene sheet (having a thickness between 0.5 to 2 mm) with a multilayer film comprising an ethylene/vinyl acetate copolymer outer layer, that is the layer that will be bonded to the absorbent mat, and another outer layer comprising a polymeric material that could be easily heat-laminated to the foamed polystyrene sheet, such as a linear low or very low density polyethylene, an anhydride modified linear low or very low density polyethylene, a styrene-butadiene block copolymer, a styrene-butadiene rubber or mixtures thereof.
  • the thickness of said film heat-laminated to the foamed polystyrene sheet may typically range between 20 microns to 100 microns.
  • Suitable absorbent mats for the pad of the present invention comprise fibers or fiber assemblies made, for instance, of cellulose pulp, rayon, naturally occurring materials, synthetic fibers with hydrophilic surface treatments and the like. Such fibers are typically arranged in the form of fluff wadding, tissue, paper or non-woven sheet material.
  • the absorbent mat is composed of an airlaid or dry-formed web of fibers, which can be bonded either by addition of a latex spray or by softening or partially melting thermoplastic fibers present in the web.
  • super-absorbent polymers are added to the fiber core.
  • the term "super-absorbent polymer" refers to one or more hydrocolloid materials capable of absorbing many times their dry weight of water.
  • the absorbent mat of the present invention is made of a material chosen from the group of super-absorbent non-woven materials.
  • preferred non-woven super-absorbent materials are the ones produced and sold by Buckeye Technologies Inc. having a water absorption capacity from about 500 to 7000 g/sqm, preferably from about 700 to 4500 g/sqm, and even more preferably from about 800 to 3000 g/sqm.
  • Said absorbent mat may cover from about 50 % to about 95 %, preferably from about 60 % to about 90 %, and even more preferably from about 70 to about 85 % of the total surface of the support.
  • the absorbent mat is laminated to the support 11 as a strip 12 having the same size of the support, along one of the axes of the support itself, and a size which is from about 50 % to about 95 %, preferably from about 60 % to about 90 %, and even more preferably from about 70 to about 85 % of that of the support along the other axis, preferably leaving two areas of the support uncovered by the absorbent material, said areas forming two parallel stripes 13a and 13b along the edges of the support, one on each side of the absorbent mat.
  • this may be achieved by one or more spots of glue that can be applied just before the tray-padding step.
  • suitable glues are hot melt adhesives, i.e. solvent-free thermoplastics-based adhesives that, when heated and in liquid form (typically above 80°C), are capable of effectively wetting substrate surfaces and that, after cooling and solidifying adhere firmly to those surfaces.
  • Suitable hot-melt adhesives are the ones sold by Sealock Ltd, UK under the trade name Sealock H1125.
  • the spots can be of a material that can be applied at an early stage, in the pad manufacturing process, and be activated, by heat, pressure, or any other suitable way, at the tray padding stage.
  • suitable materials are e.g. pressure sensitive adhesives, energy-curable adhesives, heat-activated adhesives and the like.
  • pressure sensitive adhesives refers to adhesives that adhere to the surfaces of most materials under only light pressure.
  • pressure-sensitive adhesives are based on natural and synthetic rubbers in conjunction with modified rosins or hydrocarbon resins.
  • polyacrylates, polymethacrylates, poly(vinyl ethers) and polyisobutylenes are also used frequently.
  • energy-curable adhesives refers to solvent-free adhesive compositions, containing only reactive low molecular weight, unsaturated resins which can be cured through the use of radiant energy (electron beam or ultraviolet).
  • heat-activated adhesive refers to adhesive materials, which are made sticky by the use of heat and pressure. Suitable heat-activated adhesives are polyvinylacetate, ethylene-vinyl acetate copolymers, PVC, polyacrylates, polymethacrylates and many rubber-resin compositions.
  • the stripes of support surface void of any absorbent material comprise a continuous layer of an adhesive.
  • Suitable adhesives are for example pressure sensitive adhesives, hot melt adhesives or heat-activated adhesives.
  • the pad of the present invention offers several advantages over the pads of the prior art: the adhesive spots or stripes are not affected by the absorption of liquid by the mat of absorbent material and therefore the pad is tightly and reliably secured to the bottom of the container for the whole life of the end package. At the same time, the contact between the mat of liquid absorbing material and the liquid is possible along the sides of the pad, indicated as 14 and 15 in Figure 1, which are not glued to the bottom of the container.
  • the pad of the present invention can be easily obtained by laminating a preformed support of a size suitable for the desired use to a preformed mat of absorbing material smaller in size.
  • it can be obtained by laminating discrete mats of absorbing material to a web of support and then suitably cutting the obtained laminate to get pads of the desired size.
  • the pad of the present invention can also be obtained by laminating one or more continuous strips of absorbing material to a web of support material and then cutting the obtained laminate so as to obtain a pad, such as that illustrated in Fig. 1, where the mat of absorbing material has the same size of the support in one direction, e.g. the longitudinal direction, while it is smaller in the other direction, e.g. the transversal direction.
  • Said alternative process is particularly advantageous industrially as it is a continuous process that allows controlling the amount of scrap generated and possibly to generate scrap that can completely be recycled.
  • a second object of the present invention is therefore a process for the preparation of an absorbent pad according to the present invention, comprising the steps of:
  • the composite web is converted into the single pads at the end of the laminating step by a series of transverse and, as the case maybe, longitudinal cuts.
  • Cutting can be done simultaneously in both the longitudinal and transversal direction or first in one direction and then in the other, by using any known means in the art, for instance a blade, a heated knife or a laser beam.
  • the composite web is wound into a roll and the conversion into the single pads is performed at a later stage at the pad manufacturing facility or right before the packaging operations take place at the food packaging facility.
  • the composite web contains more than one stripe of liquid absorbent material laminated onto the rigid or semi-rigid web, so that longitudinal cuts are anyway required to obtain single pads
  • said composite web will be cut only longitudinally at the pad manufacturing facility and each of the thus obtained "single" webs will be wound into a roll and converted into the single pads by transversal cuts at a later stage, for instance at the food packaging facility.
  • the longitudinal cuts to convert the composite "multiple” web into the corresponding number of "single” webs may be carried out by suitably slitting a roll of the "multiple" composite web.
  • a further specific object of the present invention is therefore a composite web of a rigid or semi-rigid web of a liquid impermeable mono or multi-layer material with longitudinally laminated thereto at least one stripe of liquid absorbent material, wherein the size and respective positioning of the rigid or semi-rigid web and of the stripes is such that said composite web can be converted into the final pads of the invention, each one of them having at least one edge which only comprises the rigid or semi-rigid support and is void of any absorbent material, by a series of transverse and possibly longitudinal cuts, said composite web being wound into a roll.
  • the liquid absorbent material can be either heat- or glue-laminated onto the rigid or semi-rigid sheet of liquid impermeable material.
  • a layer of a suitable adhesive is coated either on the stripe of absorbing material or onto the support web, before or at the time of lamination.
  • the adhesive is coated onto the support web, it is preferably distributed at least on the surface thereof that will be covered by the stripe(s). More preferably however a surface larger than that covered by the stripe will be coated so that no separate additional step will then be required to apply to the exposed portion of the surface of the support means for binding the pad to the container, as the adhesive layer on the surface of the support web that is not involved in the glue lamination of the stripe(s) will represent a suitable mean for binding the pad to the container.
  • the glue is selected from the group of hot-melt or pressure sensitive adhesives.
  • the liquid impermeable sheet preferably comprises as an outer layer a heat-activated adhesive, so that the portion of the surface of the support not covered by the liquid absorbent material will represent a suitable mean for binding the pad to the container.
  • the heat- activated adhesive is made of a material chosen from the group of ethylene-vinyl acetate copolymers, copolymers of ethylene and alkyl esters of acrylic or methacrylic acid, styrene/isoprene block copolymers, styrene/butadiene block copolymers and blends thereof.
  • Foamed polystyrene sheet web 31 is unwound from foamed polystyrene roll 32 and fed to a glue applying station 33 that applies a layer of suitable adhesive onto the surface of foamed polystyrene web 31.
  • Foamed polystyrene web 31 is then fed to lamination station 34.
  • the stripe or stripes of absorbing material 40 are unwound from absorbent material roll or rolls 41 and also fed to laminating station 34 where they are laminated to foamed polystyrene web 31.
  • the composite web 50 is then fed to a diamond-shaped punch press 35 that forms the rounded edges 26 in the pad showed in Figure 4, needed to conform the pad to the bottom of the tray.
  • Composite web 50 is then fed to a cutting station 36 that cuts the web in single pads 10.
  • the diamond-shaped fragments that are cut out from composite web 50 consist of foamed polystyrene material coated with a thin layer of adhesive that can be recycled in the foamed polystyrene sheet manufacturing cycle without any further treatment.
  • Foamed polystyrene sheet web 31 is unwound from foamed polystyrene roll 32 and fed to a glue applying station 33 that applies a layer of suitable adhesive onto the surface of foamed polystyrene web 31.
  • Foamed polystyrene web 31 is then fed to lamination station 34.
  • the stripe or stripes of absorbing material 40 are unwound from absorbent material roll or rolls 41 and also fed to laminating station 34 where they are laminated to foamed polystyrene web 31.
  • the composite web 50 is then fed to a cutting station 135 that longitudinally cuts the web in single webs 51, which are then individually wound into separate rolls 52. Rolls 52 are then cut transversely into single pads 10 by means of a cutting device 136.
  • a fourth object of the present invention is a package comprising the absorbent pad of the present invention and a container.
  • Suitable containers can be pouches, bags or trays made of mono- or multi-layer thermoplastic materials.
  • the container is a tray made of plastic material.
  • Suitable plastic materials for the container are PVC, polypropylene, polyesters, poly(lactic acid) and foamed polystyrene.
  • the inner surface of the container is provided with a gas barrier composite film made of plastic material.
  • the rigid or semi-rigid liquid impermeable support of the absorbent pad is made of the same material as the tray and has the same shape and size of the bottom of the tray, so that it snugly fits the bottom of the tray, completely covering the liquid absorbed by the pad.
  • a rectangular tray-shaped container 20 made of foamed polystyrene comprises a base wall 21 completely covered by absorbent pad 10, a continuous, tapered side wall 22 upstanding therefrom and an outwardly extending peripheral rim 23.
  • the inner surface of the tray is provided with a gas barrier composite film 24.
  • the absorbent pad 10 comprises a rigid or semi-rigid support 11 and a mat of liquid absorbent material 12.
