    摘要: The present disclosure includes a method for determining a melt strength includes extruding one or more polymers to form the polymer film (104), passing the polymer film (104) at least partially around a measurement roll (130) coupled to a force measuring device (154), at least partially around a chill roll ((132) downstream of the measurement roll (130), and through a nip (160) defined between two nip rolls (134, 136), and measuring a force exerted on the measurement roll (130) by the polymer film (104) using the force measuring device (154). The polymer film( 104) is at least partially molten when contacting the measurement roll (130). A system includes an extruder (102), a measurement roll (130) couple to one or more load cells, a chill roll (132)coupled to a drive motor (157), at least two nip rolls (134, 136) downstream of the chill roll (132), and a take-up roll (166) downstream of the nip rolls (134, 136). The load cells measure a force exerted by the molten polymer film on the measurement roll (130).
