Abstract

A polymer blend including a vinylidene chloride interpolymer; an ethylene-acrylate interpolymer; and optionally one or more additives selected from the group consisting of stabilizers, plasticizers, and processing aids is provided. Also provided is an extruded film and a packaging or container which includes the film.

Claims (15)

1. A polymer blend comprising:

a vinylidene chloride interpolymer comprising units derived from one or more di- or multifunctional vinyl monomers;

an ethylene-acrylate interpolymer; and

optionally one or more additives selected from the group consisting of stabilizers, plasticizers, and processing aids.

2. The polymer blend according to claim 1 , wherein the vinylidene chloride interpolymer comprises units derived from vinylidene chloride and units derived from one or more comonomers.

3. The polymer blend according to claim 1 , wherein the vinylidene chloride interpolymer comprises units derived from vinylidene chloride and units derived from one or more comonomers selected from the group consisting of methyl acrylate and butyl acrylate.

4. The polymer blend according to claim 1 wherein the vinylidene chloride interpolymer comprises units derived from vinylidene chloride and vinyl chloride.

5. The polymer blend according to claim 1 , wherein the one or more di- or multifunctional vinyl monomers is selected from the group consisting of 1,2 ethanediol diacrylate, 1,4 butanediol diacrylate, and 1,6 hexanediol diacrylate.

6. The polymer blend according to claim 1 , wherein the ethylene-acrylate interpolymer comprises units derived from ethylene and units derived from two or more acrylate comonomers.

7. The polymer blend according to claim 1 , wherein the one or more additives are selected form the group consisting of ethylene vinyl acetates, acrylic polymers and vinyl chloride vinyl acetate copolymers.

8. An extruded film formed from the polymer blend according to claim 1 .

9. The extruded film of claim 8 wherein the film is a monolayer film.

10. The extruded film of claim 8 laminated with one or more other films.

11. A coextruded multi-layer film comprising an external layer formed from the polymer blend according to claim 1 .

12. A container or packaging comprising the extruded film according to claim 8 .
