We are a Flexible Plastic Film Manufacturer in Brazil and we produce some LDPE and HDPE film rolls. We need a machine that would rewind those rolls and in the process create a detachable plastic bag. It's very a very commum product used at supermarkets an grocery stores but they´re used to be produced in small widths. We need a machine that can perform that cut/seal on large widths (1, 600 milimeters). The result should be a large plastic film roll with that can be detached into bags. The machine should be able to allow lenght adjustment. I'm attaching a simple small detachable plastic film roll picture as an example. I hope you can understand the description above. If you need further information please let me know. Regards.
