Improve stretch wrap film capacity-A

Raw material extrusion is blocked.

① Factors of raw materials themselves. Even for the same linear material (LLDPE), their flow indexes are different (1-2g/10min). The lower the flow index of raw materials, the more difficult it is to extrude raw materials. Solution: Please pay attention to the flow index of the raw materials you use.

② The filter screen is blocked. When the recycled material is used as the winding film, the filter screen is often blocked. If the filter screen is blocked, the output will be affected. Solution: frequently replace the filter screen; Pay attention to the cleanliness of raw materials; Two 80 mesh strainers are considered.

③ Die head. In order to reduce the die pressure and increase the extrusion amount, the die mouth can be widened to reduce the extrusion pressure.
