Definitions

  • This invention relates to packaging particularly but not exclusively for foodstuffs and degradable products.
  • the invention relates in particular to an electrochemical sensor incorporated into packaging to provide an indication of the condition of the packaged product.
  • Foodstuffs and other products are stored and distributed inside packages. These packages have several functions including containment, maintenance of a specific atmosphere and prevention of contamination and tampering. Packaging technology has advanced and new materials are available which allow increased storage life and increased protection for the packaged product. Tamper-proof packaging is also available.
  • MAP modified atmosphere packaging
  • polymer films with excellent gas barrier properties has allowed a modified atmosphere to be maintained by prevention of diffusion from inside or outside the package.
  • the improvement in the effectiveness and performance of such packages has been reflected in the extension of the use of such packaging to a variety of products including pharmaceuticals, cosmetics and chemicals. In such cases the package provides an effective barrier containing a controlled artificial environment.
  • Loss of package integrity and the consequent loss of a modified atmosphere or impairment of the barrier may not be evident by observation. Small holes which may be caused by incorrect sealing, breakage or tampering are usually invisible. Similarly the loss of a modified atmosphere may not result in any visual change to the product. The loss of storage life and compromised safety of a product may only be observed by a consumer, perhaps with unfortunate results.
  • UK patent application 9401557.2 discloses use of reversible oxygen and carbon dioxide sensors for this purpose. Such sensors may indicate package integrity but they do not allow accurate measurement of the atmosphere within the package. In cases where the residual package oxygen level is important, a colour changing sensor may not allow sufficiently accurate interpretation. A colour change sensor cannot be used in an opaque package. Furthermore colour change sensors are unsuitable for measurement of small quantities of specific gases and they cannot be used to measure more than one gas.
  • a gas impermeable package for an article incorporates a gas impermeable barrier and includes an electrochemical sensor adapted to detect an analyte disposed in the interior of the package and adapted to generate a signal on the exterior of the package.
  • the electrochemical sensor may be adapted to detect one or more of a wide variety of analytes at precise concentrations. Destructive testing is avoided and the acceptability of every package may be ascertained. This is important for high value products, for example whole carcasses or other bulk foodstuffs.
  • a preferred package further comprises a detector adapted to provide a display in response to said signal.
  • the detector may be integral with the package.
  • the detector is releasably engagable with the sensor on the exterior of the package.
  • the detector preferably incorporates a power supply. Preferred detectors may be hand held or are otherwise portable.
  • the electrochemical sensor may be conductimetric, potentiometric, amperometric or impedometric.
  • Preferred analytes are gases or volatile liquids for example oxygen, carbon dioxide, hydrogen sulphide, ethanol, alkyl sulphide, ketones, aldehydes, esters, ammonia or amines.
  • Preferred electrochemical sensors may be manufactured by screen printing, lithographic or other thick film deposition processes, for example as disclosed in PCT/GB93/02076. Such sensors may be easy to fabricate and are inexpensive. Enzymic sensors may be employed. Dried stabilised enzymes may be provided together with a portion of aqueous solvent which may be disposed in a releasable container in the proximity of the electrode. A covering membrane may be used to prevent leaching or degradation of the constituents of the sensor.
  • an electrochemical sensor in accordance with the invention affords the advantages of simple and economical manufacture and use, a high speed of response measurement and accuracy and affords the facility of measurement of a wide range of analytes.
  • the analytes include gases, bacteria, pH, conductivity and additives.
  • Multiple sensors responsive to a plurality of analytes may be afforded.
  • a multiplicity of single use sensors may permit multiple testing of a package so that an analyte may be monitored during a prolonged period, eg throughout the lifetime of a product.
  • An additive may be incorporated within a package in accordance with the invention to afford an indication of tampering or for verification of genuine goods.
  • An electrochemical sensor adapted to detect a change in the amount of an additive gas within a package may afford a signal indicating escape of the gas from the package due to tampering or other loss of integrity.
  • Such an additive may be a gas provided at a trace concentration for which the sensor may be particularly adapted.
  • an atmospheric gas may be provided at a different concentration to that of the surrounding atmosphere.
  • An additive or physical property of the contents of a package may be selected to provide confirmation of genuine goods. Such an addition or property may be changed from time to time to inhibit unauthorised copying.
  • a preferred embodiment of the invention may serve to indicate that a product has been packaged correctly.
  • the correct flushing of the package with a modified atmosphere is critical to maintain the product in a safe condition during storage and distribution.
  • a low oxygen level for example below 1% is required in many cases.
  • a sensor responsive to oxygen may confirm that a suitably low concentration has been achieved.
  • Further preferred embodiments of the invention may indicate breakage or incorrect sealing of a package. Loss of the package atmosphere and replacement by air may be detected.
  • the sensor may be adapted to monitor the gas or humidity level within a package to indicate whether these are the same as the ambient atmosphere by comparison with an external sensor.
  • Provision of a portable detector allows testing of packages to be carried out at any convenient juncture during manufacture, distribution and retail. For example the condition and quality of a food product may be observed during transportation, storage or retail using packaging of the present invention.

  • the sensor element 1 may be attached by welding, for example thermal or ultrasonic welding, by an adhesive or other bonding process so as to form a gas impermeable seal.
  • the sensor l may comprise a polymeric substrate formed from polyester, polyethylene terephthalate or polycarbonate or a laminate of polymers which is physically compatible with the packaging material 2. Physical compatibility is important so that stresses are not imposed on the seal due to thermal or other environmental effects. Compatibility is also important to allow physical flexibility and resilience in use. Alternative materials include foil, metallised films and waxed papers. Electrical contacts 6 and 7 communicate with the exterior of the package and are connected to a sensing layer 8 incorporating electrodes. A protective layer 9 may overlie the sensing layer 8 and a spacer 14 may allow gas circulation in the proximity of the sensor in use.
  • FIG 2 shows an embodiment of the invention wherein the sensor is a Clark type electrode.
  • Small holes 4 extending through the substrate 5 may be formed by laser photo-ablation.
  • the holes 4 are filled with conducting materials 6 and 7 to form the sensor electrodes.
  • a conducting ink may be deposited onto the substrate 5.
  • Preferred inks may contain silver, gold or platinum particles together with a resin binder to provide a gas tight seal.
  • the electrodes may be incorporated into the patch substrate during manufacture, for example by inclusion of fine metal strands or particles to provide naturally conductive regions on the substrate 5.
  • the electrodes are covered with an electrolyte layer 8 which can be deposited by any convenient means for example printing or spray coating.
  • Preferred electrolyte layers include hydrogels, for example a gelatin/glycerol/water mixture.
  • the glycerol or other hygroscopic material serves to retain the water content of the gel and ensure conductivity.
  • Alternative hydrogels may include PVA or commercially available polymer electrolytes such as Nafion or Promeon.
  • FIG. 12 An example of the response of such a sensor to alternating streams of nitrogen and air is shown in Figure 12.
  • the "solid state" oxygen sensitive electrode was fabricated by dosing 2 ⁇ l of a 5% Nafion solution in a mixture of alcohol and water onto a sensor comprising carbon and silver electrodes printed onto a polyester substrate. Currents were recorded under a polarisation potential of 800 mV.
  • a highly water retentive membrane may be laminated onto the electrode to form an electrolyte layer.
  • a gas permeable membrane 9 serves to isolate the electrolyte layer from the contents of the package.
  • a Clark electrode of the kind described above measures oxygen directly.
  • Indirect oxygen measurement may also be employed.
  • a redox active film for example Prussian blue may be employed.
  • Further electrochemically active species which may be used to determine oxygen are tetraphenyl porphyrins .
  • the use of such materials as disclosed in U C S Chem Comm 1990, 721 may give rise to higher sensitivity. Reduction of the porphyrin from the stable oxidised form to the oxygen sensitive reduced form provides an integral activation step which avoids the need for the sensor to be kept in an oxygen free environment prior to use.
  • Figure 3 illustrates a laminated structure wherein the sensor substrate 5 is formed in two parts separated by a metallic layer 10.
  • the metallic layer 10 may be printed or vapour deposited. Such a configuration exhibits integrity against leakage.
  • a plurality of metallic layers may be provided.

  • Figure 6 illustrates an alternative configuration to that shown in Figure 4.
  • an electrode array 6, 7 is printed onto the outer surface of the pack and small regions of the pack, adjacent the electrodes are rendered gas permeable.
  • the electrode assembly is covered with an electrolyte layer and barrier film 2.
  • Figure 7 shows an alternative arrangement avoiding the need for a cut and patch arrangement. Electrical contact is made using very fine holes filled with resin based conductive inks which serve as a gas barrier. The risk of leakage around the contacts can be further minimised by use of evaporated metal coatings.
  • This embodiment has the advantage that the sensor can be integrated into the packaging material at any convenient point of manufacture.
  • the contact holes can be drilled by laser and filled and the electrolyte layer 8 and protective film 9 applied by an on-line procedure.
  • Appropriate selection of the electrode materials can provide a sensor configured as a battery to drive a permanently attached external display 13.
  • one electrode may be formed of zinc and the other of silver to generate a current in use.

  • the exposed electrode can be made extremely small to minimise the perturbation of the atmosphere caused by each measurement.
  • the electrolyte layer 8 may comprise a conductor, the impedance of which changes as a consequence of the local environment.
  • Conducting polymers such as polypyrrole, polyaniline or polythiophene may be employed. These materials are electrically conducting in the oxidised state but are non ⁇ conducting in the reduced state.

  • a sensing circuit 15 is printed on the interior of a packaging film and a corresponding analytical circuit 16 is printed on the exterior of the film.
  • a suitable wave form applied to the exterior circuit induces current flow in the interior circuit which in turn generates a back EMF limiting the current flow in the exterior circuit .
  • the magnitude of the current flow in the inner circuit is limited chemically by an electrochemical sensor as described above. Analysis of the current-voltage relationship in the outer circuit allows the impedance of the inner circuit to be calculated.
  • the configuration of the pack may constitute a capacitor as shown in Figure 10, the change in impedance at the inner plates of the capacitor 20 and 21 being monitored. Alternatively a change in the impedance of the sensing layer may be detected.
