This disclosure provides a novel container, poly(neopentyl-2,5-furandicarboxylate) (PNPGF) and for methods of use thereof.

What is claimed is: 
     
         1 . A container comprising poly(neopentylene-2,5-furnadicarboxylate) or PNPGF. 
     
     
         2 . A container according to  claim 1 , wherein an outer layer defining an exterior surface and an inner layer defining an interior surface and interior space, wherein the outer layer comprises PNPGF. 
     
     
         3 . A container according to  claims 1  and  2 , wherein a multilayer co-polyester exists further wherein said co-polyester comprises: poly(neopentylene-2,5-furnadicarboxylate) or PNPF, poly(ethylene-2,5-furandicarboxylate) (PEF); poly(trimethylene-2,5-furandicarboxylate) (PTF); poly(butylene-2,5-furandicarboxylate) (PBF);
 poly(isosorbide-2,5-furandicarboxylate) (PISF); poly(isoidide-2,5-furandicarboxylate) (PIIF); poly(isomannide-2,5-furandicarboxylate) (PIMF); poly(neopentyl-2,5-furandicarboxylate) (PNPGF); poly(ethylene-2,5-furandicarboxylate) with 10 mol. % 1,8-naphthalene dicarboxylate (PEF-PEN); poly(l,4-phenylene-2,5-furandicarboxylate) (PCHF); poly(l,2-dimethylphenylene-2,5-furandicarboxylate) (PDMFF); and any combinations thereof, mixtures thereof, or copolymers thereof. 
 
     
     
         4 . A container according to  claims 1  and  2 , wherein the container is stretch blow-molded. 
     
     
         5 . A container according to  claims 1  and  2 , wherein each of the outer layer and the inner layer independently has a thickness from about 0.01 mm to about 2.5 mm. 
     
     
         6 . A container according to  claims 1  and  2 , wherein either one or both of the outer layer and the inner layer comprises PNPGF. 
     
     
         7 . A container according to  claims 1  and  2 , wherein at least one of the outer layer, or the inner layer further comprises a colorant, a UV blocker, a lubricant, a slip agent, a processing aid, an antioxidant, an antimicrobial agent, a thermal stabilizer, or any combination thereof. 
     
     
         8 . A packaged beverage comprising the container according to  claims 1  and  2  and a beverage disposed in the interior space of the container. 
     
     
         9 . A preform comprising:
 a. an outer layer defining an exterior surface and an inner layer defining an interior surface, wherein the outer layer comprises a polyester and the inner layer comprises PNPGF.   
     
     
         10 . A method of making a container, the method comprising:
 a. providing a preform according to  claim 9 ; and   b. stretch blow-molding the preform to provide the multilayer container.   
     
     
         11 . A 2,5-furandicarboxylate polyester or co-polyester polymer selected from poly(neopentyl-2,5-furandicarboxylate) (PNPGF); poly(ethylene-2,5-furandicarboxylate) with 10 mol. % 1,8-naphthalene dicarboxylate (PEF-PEN); poly(1,4-phenylene-2,5-furandicarboxylate) (PCHF); and poly(1,2-dimethylphenylene-2,5-furandicarboxylate) (PDMFF).
