  • Sterilization tape currently exists.
  • Conventional sterilization tape is typically paper- based tape that uses temperature or chemical sensitive inks that change color when subjected to heat, humidity, and/or chemicals associated with sterilization cycles.
  • Figure 1 shows a prior art sterilization tape embodiment.
  • the prior art sterilization tape (11) can contain 4 separate layers.
  • the first layer is a silicon release coating layer (10).
  • Adjacent to the silicone release layer is a sterilization ink layer (20).
  • a paper substrate layer (30) Adjacent to the sterilization ink layer (20) is a paper substrate layer (30).
  • an adhesive layer adjacent to the paper substrate layer (30) is an adhesive layer (40).
  • An optional release line may be added adjacent the adhesive layer.
  • Prior art sterilization tape is typically used in conjunction with polypropylene surgical wrap material. Surgical instruments are placed in a stainless steel tray, the tray is wrapped in wrap material, and the material is then folded over to enclose the instruments in the wrap. The indicator tape is then used to securely close the wrapped bundle. The bundle is then subjected to a sterilization cycle. During the cycle, the ink on the indicator tape changes color, this indicates that the bundle has been exposed to a hospital sterilization cycle and is ready for use in surgery. At the completion of the surgery, the polypropylene wrap and tape material are discarded. The polypropylene wrap can be easily recycled, but the paper-based tape contaminates the polypropylene because the tape burns when the polypropylene melts. Changing to a polymeric, plastic based tape will enable the wrap/tape combination to be easily recycled into the plastic hospital waste stream.
  • a printed polymeric dual surface substrate which includes at least one polymeric layer, an ink layer and a release coating layer is disclosed.
  • the polymeric dual surface substrate includes at least two polymeric layers, an ink layer, and a release coating layer.
  • polymeric substrate In order to integrate polymeric substrate into a traditionally paper based sterilization tape application, several factors have to be considered.
  • the polymeric substrate needs to have distinct characteristics in order for it to be usable as a sterilization tape substrate.
  • polymeric carrier tape One important feature of a polymeric carrier tape is that it be recyclable within the polypropylene waste stream generated by hospitals.
  • a second important feature of the carrier is that each surface has the required characteristics to function effectively as a sterilization tape.
  • the polymeric based sterilization tape must enable user to tear strips with a dispenser.
  • the process used to produce the polymeric based sterilization tape must limit the exposure of the ink to heat to ensure it isn't activated too soon.
  • the polymeric carrier layer must have certain properties on each outer surface.
  • the first surface must accept ink, accept the release coating layer, and must not let the ink travel through the layer.
  • the tape surface is polymeric and must have non-polar properties. On the other hand, the first surface must also not repel polar substances, like steam. This first surface must also enable steam to travel to ink.
  • the second surface must accept adhesive and prevent adhesive from migrating through the layer. It is important that the adhesive layer and ink/silicon layers do not interact.
  • the polymeric layer will eventually be used as a tape, so it is also important that the surfaces work to be self-windable.
  • the adhesive (attached to the second surface of the polymeric carrier layer) must adhere to the second surface of the film, but not the first surface.
  • the polymeric dual surface can be a single layer, so long as both surfaces are present with these characteristics.
  • the polymeric dual surface substrate can be any number of polymeric layers so long as the outer surfaces contain these properties.
  • the polymeric dual surface substrate can be texturized on one or both surfaces to create these properties. In one embodiment the texturizing is embossing.
  • Any recyclable polymer or combination of recyclable polymers can be utilized as the substrate for the current invention.
  • Recyclable polymers can be grouped into categories based on their numerical categorization. Recycling symbol 1 marks PET or PETE (polyethylene terephthalate) such as soft drink bottles. Recycling symbol 2 marks HDPE (high density polyethylene) such as milk jugs and trash bags. Recycling symbol 3 marks V (vinyl) or PVC (polyvinyl chloride) such as piping and some medical equipment. Recycling symbol 4 marks LDPE (low density polyethylene) such as dry cleaning bags. Recycling symbol 5 marks PP (polypropylene) such as medicine bottles and straws. Recycling symbol 6 marks PS (polystyrene) such as disposable plates and egg cartons. Recycling symbol 7 marks miscellaneous plastics such as polycarbonate and other non-commodity polymers.
  • the polymeric layer is comprised of any one or combination of any of the recyclable polymers previously noted.
  • the at least one polymeric layer is comprised of polypropylene polymer.
  • the polypropylene of the polymeric substrate of the sterilization tape can comprise a polypropylene homopolymer, a polypropylene copolymer, or a mixture of two or more of any of the foregoing polypropylene polymers.
  • the polypropylene copolymer comprises a random copolymer, a block copolymer, or a mixture of two or more of any of the foregoing copolymers.
  • Different grades of polypropylene can be used in the polypropylene substrate.
  • Isotactic, semicrystalline grades of polypropylene were used. Any other desired grade, including atactic and syndiotactic grades, can also work in the invention.
  • a small percentage of additional polymer can be mixed with the polypropylene because polypropylene polymers are considered recyclable provided they are contaminated by no more than 2% of another polymer in addition to the polypropylene.
  • the carrier can therefore be made from polymers other than polypropylene provided that the overall mass percentage of the other polymer remains below 2% in the hospital waste stream.
  • the polypropylene substrate of the sterilization tape contains up to 2% of an additional polymer.
  • the additional polymer is polyethylene.
  • PET polyethylene terphthalate
