Abstract
A multilayer film is provided. The film includes a first inert layer, a first tie layer, a nail sealable layer, a second tie layer, and a second inert layer. Where, the nail sealable layer is between the first tie layer and the second tie layer, the first tie layer is between the first inert layer and the nail sealable layer, the second tie layer is between the second inert layer and the nail sealable layer, the total film thickness is between 0.002 inch and 0.010 inch, and the film has a Water Vapor Transmission Rate of less than 0.5 grams per one hundred square inches per day.
Claims20
A multilayer film, comprising:
- a first inert layer;
- a first tie layer;
- a nail sealable layer;
- a second tie layer;
- and
- a second inert layer;
- wherein the nail sealable layer is between the first tie layer and the second tie layer;
- wherein the first tie layer is between the first inert layer and the nail sealable layer;
- wherein the second tie layer is between the second inert layer and the nail sealable layer;
- and
- wherein the total film thickness is between 0.002 inch and 0.010 inch and wherein the film has a Water Vapor Transmission Rate of less than 0.5 grams per one hundred square inches per day.
A process for forming a multilayer film, comprising:
- providing a first extruder for extruding a first material;
- providing a second extruder for extruding a second material;
- providing a third extruder for extruding a third material;
- providing a die fluidly coupled to the first extruder, the second extruder, and the third extruder;
- and
- simultaneously co-extruding the first material, the second material, and the third material through the die to form a multilayer film, wherein the multilayer film comprises:
- a first inert layer of the first material;
- a first tie layer of the second material;
- a nail sealable layer of the third material;
- a second tie layer of the second material;
- and
- a second inert layer of the first material;
- wherein the nail sealable layer is between the first tie layer and the second tie layer;
- wherein the first tie layer is between the first inert layer and the nail sealable layer;
- wherein the second tie layer is between the second inert layer and the nail sealable layer;
- and
- wherein the total film thickness is between 0.002 inch and 0.010 inch and wherein the film has a Water Vapor Transmission Rate of less than 0.5 grams per one hundred square inches per day.
