摘要 |
<p>A thermoplastic solid backing film manufactured by the co-extrusion of three polymer compositions wherein die-lip build up is avoided by adjusting the amount of filler present in each polymer composition. The first and third polymer compositions are such that substantially no die-lip build up occurs when these compositions are extruded through a die however the second polymer composition is such that there would be substantial die-lip build up if it was extruded adjacent a die-lip. The presence of the first and third polymer compositions prevents the second polymer composition from contacting the die-lip during manufacture of the backing film. The thermoplastic solid backing film can be incorporated in a resilient floor covering and in floor tiles.</p> |
