A method of assembling an exhaust treatment system for an internal combustion engine comprising a substrate disposed in a canister and an insulating and cushioning mat material interposed between an outer surface perimeter of the substrate and an inner wall of the canister comprising:
- inserting the insulating and cushioning mat material into a film laminate sleeve;
- subjecting the insulating and cushioning mat material to a compression process that compresses the mat material to a nominal thickness that is less that that of an uncompressed thickness;
- sealing the insulating and cushioning mat material in the film laminate sleeve;
- and
- inserting the mat into the canister.
An exhaust system for an internal combustion engine comprising:
- an exhaust treatment system having a substrate disposed in a canister;
- an insulating and cushioning mat material interposed between an outer surface perimeter of the substrate and an inner wall of the canister;
- and
- a film laminate sleeve compressing and sealing the insulating and cushioning mat material to a nominal thickness that is less than that of an uncompressed thickness.
An exhaust treatment system for an internal combustion engine comprising:
- an insulating and cushioning mat material disposed in the exhaust gas treatment system;
- and
- a film laminate sleeve vacuum packed and sealing the insulating and cushioning mat material to a nominal thickness that is less than that of an uncompressed thickness.
