Patent ID: 7318590

Claim:
A method of making a resealable sealing product for a multi-well plate, which comprises a) selecting a sealing material of an optimum film, or mat material for a specific resealable sealing application; b) treating said sealing material; and c) directly coating said sealing material with an adhesive in a multi-well pattern format using Gravure, screen, rotary screen, flexographic, pad printing or dry transfer techniques; wherein the adhesive covers substantially all of the surface area of the sealing material that contacts the multi-well plate but does not cover the well area of the multi-well plate; and; wherein the sealing material is selected from the group consisting of, fluorinated and non-fluorinated materials selected from the group consisting of perfluoroalkoxy tetafluoroethylene copolymer resin (PFA), ethylenechlorotrifluoroethylene copolymer resin (E-CTFE), ethyleneterafluoroethylene copolymer resin (E-TFE), polychlorotrifluoroethylene (CTFE) homopolymers and copolymers, polyvinylidine fluoride (PVDF), tetrafluoroethylene-hexafluoropropylene (FEP), polytetafluoroethylene (PTFE), expanded PTFE, porous PTFE, woven glass impregnated with PTFE, skived or skived plus calendared PTFE, dyneon TFM, polyimides, polyolefins, acrylic polymers and copolymers, vinyl halide polymers and copolymers, ethylene-methyl methacrylate copolymers, acrylonitrilestyrene copolymers, ABS resins, ethylene-vinyl acetate copolymers, natural and synthetic rubbers, butadienestyrene copolymers, polyisoprene, synthetic polyisoprene, polybutadiene, butadiene-acrylonitrile copolymers, polychloroprene rubbers, polyisobutylene rubber, ethylenepropylene rubber, ethylene-propylene-diene rubbers, isobutylene-isoprene copolymers, polyurethane rubbers, polyamides, polyesters, polycarbonates, polyimides, polyethers, polyolefins, fluoropolymer laminates, acrylonitrile-methyl acrylate copolymers and laminates of acrylonitrile-methyl acrylate copolymers and polychlorotrifluoroethylene (CTFE) homopolymers and copolymers.
