A porous food casing consisting essentially of a film of food grade thermoplastic having a plurality of interconnected interstices therein. The interstices are defined by a porosity modifier selected from the group consisting of soybean oil, peanut oil, corn oil, glycerin, polyethylene glycol, monol
A porous food casing consisting essentially of a film of food grade thermoplastic having a plurality of interconnected interstices therein. The interstices are defined by a porosity modifier selected from the group consisting of soybean oil, peanut oil, corn oil, glycerin, polyethylene glycol, monolaurate, mineral oil, polyoxyethylene, sorbitan monostearate, sorbitan monooleate and glycerol monooleate. The interstices are in a range of approximately 0.002 to 1 micron and the casing has a water vapor permeability in a range of about 1 to 1500 gms/m2/min.

A method as set forth in claim 1 wherein said step of providing a head deck mask portion includes providing a mounting plate having at least one aperture extending therethrough. 6. A method of masking an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a head deck mask portion and engaging the head deck mask portion with a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck; providing a crankcase mask portion having an engaging portion to engage a lower end of a cylinder bore cavity of the engine block and a holding portion connected to the engaging portion and disposing the crankcase mask portion in a crankcase chamber of the engine block and engaging the lower end of the cylinder bore cavity of the engine block to prevent over-spray of the thermally sprayed coating into the crankcase chamber; and wherein the holding portion includes a first portion extending axially and a second portion extending at an angle to the first portion, the second portion abutting the engaging portion. 7. A method as set forth in claim 6 including the step of providing a holding plate having at least one aperture extending therethrough to engage an exhaust system, the first portion being disposed in the at least one aperture. 8. A method of masking an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a head deck mask portion and engaging the head deck mask portion with a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck; providing a non-inflatable crankcase mask portion and disposing the crankcase mask portion in a crankcase chamber of the engine block and engaging a lower end of a cylinder bore cavity of the engine block to prevent over-spray of the thermally sprayed coating into the crankcase chamber; and wherein said step of providing a head deck mask portion includes providing a mounting plate having at least one aperture extending therethrough, providing an insert, and disposing the insert in the at least one aperture. 9. A method of masking an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a head deck mask portion including a mounting plate having at least one aperture extending therethrough, providing an insert, and disposing the insert in the at least one aperture and engaging the head deck mask portion with a head deck of an engine block to prevent over-spray of a thermally sprayed coating on the head deck; providing a crankcase mask portion and disposing the crankcase mask portion in a crankcase chamber of the engine block and engaging a lower end of a cylinder bore cavity of the engine block to prevent over-spray of the thermally sprayed coating into the crankcase chamber; and wherein said step of providing the head deck mask portion includes providing a ring and disposing the ring in the at least one aperture and connecting the mounting plate to carry the insert. 10. A method of masking a head deck of an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a plate and engaging the plate with a head deck of an engine block to prevent over spray of a thermally sprayed coating on the head deck, the plate including at least one aperture extending therethrough; and providing an insert and disposing the insert in the at least one aperture and having an aperture extending therethrough. 11. A method of masking a head deck of an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a plate and engaging the plate with a head deck of an engine block to prevent over spray of a thermally sprayed coating on the head deck, the plate including at least one aperture extending therethrough; providing an insert and disposing the insert in the at least on e aperture and having an aperture extending therethrough; and providing a ring and disposing the ring in the at least one aperture and engaging the plate to carrying the insert. 12. A method of masking a crankcase chamber of an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing a non-inflatable engaging portion being made of an elastic polymeric material and disposing the engaging portion in a crankcase chamber of an engine block and engaging a lower end of a cylinder bore cavity of the engine block to prevent over-spay of the thermally sprayed coating into the crankcase chamber; and providing a holding portion connected to the engaging portion to hold the engaging portion in compression with the engine block. 13. A method of masking a crankcase chamber of an engine block to be thermally sprayed with a coating, said method comprising the steps of: providing an engaging portion and disposing the engaging portion in a crankcase chamber of an engine block and engaging a lower end of a cylinder bore cavity of the engine block to prevent over-spay of the thermally sprayed coating into the crankcase chamber; providing a holding portion connected to the engaging portion to hold the engaging portion in compression with the engine block; and wherein the holding portion includes a first portion extending axially and a second portion extending at an angle to the first portion, the engaging portion being connected to the second portion. 14. A method of masking an engine block for thermally spraying a coating, said method comprising the steps of: providing an engine block to be thermally sprayed; providing a head deck masking for masking a head deck of the engine block; providing a non-inflatable crankcase masking having a portion being made of an elastic polymeric material for masking a portion of a crankcase chamber of the engine block; disposing the crankcase masking in the crankcase and engaging the crankcase masking with a lower end of a cylinder bore cavity of the engine block; and engaging the head deck masking against the head deck of the engine block, wherein the masking prevents over-spray of a coating, that is thermally sprayed on a wall of the cylinder bore cavity of the engine block, from adhering to the head deck and entering the crankcase chamber.
