          as evidence of obviousness:                                                 


          Edwards             4,526,919                Jul.  2, 1985                  
          Uno et al. (Uno)    4,650,747                Mar. 17, 1987                  
          Canadian patent     798908              Nov. 12, 1968                       
               All of the claims on appeal are rejected under 35 U.S.C.               
           103 as being unpatentable over Edwards alone or taken with                
          the Canadian patent and Uno.                                                
               We refer to the brief and reply brief and to the answer                
          and supplemental answer for a complete exposition of the                    
          opposing viewpoints expressed by the appellants and by the                  
          examiner concerning the above noted rejection.                              
                                       OPINION                                        
               For the reasons set forth below, this rejection cannot be              
          sustained.                                                                  
               The appealed claim 12 process distinguishes over Edwards               
          in a variety of respects including the formation of a                       
          polyethylene film via extrusion coating at the here claimed                 
          temperature range of a composition comprising a polyethylene                
          component having a melt index in the range of about 10 up to                
          100 dg per minute at 190EC and having a sufficiently broad                  
          molecular weight distribution so that the resulting                         
                                          3
