Claims
- 1. A multilayer polymeric packaging material, comprising:
- (a) a first layer, constituting the outer layer of said packaging material having first and second surfaces, said first surface being roughened over substantially the entire surface area of said first surface;
- (b) a second layer of a polymeric adhesive, said second layer having first and second surfaces, said first surface of said second layer disposed in surface-to-surface contact with said second surface of said first layer;
- (c) a third layer of a foil, said third layer having first and second surfaces, said first surface of said third layer disposed in contact with said second surface of said second layer;
- (d) a fourth layer of a polymeric adhesive, said fourth layer having first and second surfaces, said first surface of said fourth layer disposed in contact with said second surface of said third layer; and
- (e) a fifth layer of a polymeric sealant film, said fifth layer having first and second surfaces, said first surface of said fifth layer disposed in contact with said second surface of said fourth layer.
- 2. A multilayer polymeric packaging material as in claim 1, wherein said fifth layer of a polymeric sealant film is a multilayer sealant film.
- 3. A multilayer polymeric packaging material as in claim 2, wherein said multilayer sealant film is a five layer film having the following layer structure in order: a layer comprising a polymer selected from the group consisting of HDPE and MDPE; a layer comprising an adhesive; a layer comprising EVOH; a layer comprising an adhesive; and a layer comprising a heat sealable polymer wherein said layer comprising a polymer selected from the group consisting of HDPE and MDPE is disposed in surface-to-surface contact with said second surface of said fourth layer of said polymeric adhesive.
- 4. A multilayer polymeric packaging material comprising:
- (a) a first layer, constituting the outer layer of said packaging material, having first and second surfaces, said first surface being roughened over substantially the entire surface area of said first surface;
- (b) a second layer of a polymeric adhesive, said second layer having first and second surfaces, said first surface of said second layer disposed in surface-to-surface contact with said second surface of said first layer; and
- (c) a third layer of a polymeric sealant film wherein said third layer of polymeric sealant film is a multilayer sealant film having five layers consisting of the following structure in order: a layer comprising a polymer selected from the group consisting of HDPE and MDPE; a layer comprising an adhesive; a layer comprising a polymer selected from the group consisting of EVOH and nylon; a layer comprising an adhesive; and a layer comprising a heat sealable polymer, wherein said layer comprising a polymer selected from the group consisting of HDPE and MDPE is disposed in surface-to-surface contact with said second surface of said second layer of said polymeric adhesive.
