Good morning everyone,
Recently, we tried to produce HDPE bags in rolls . The thickness was 11-12μm.
During production we faced the following problems.
1. The bubble was unstable when we tried to give it height. We tried a long neck shape.
2. The rolls were easily torn in the TD direction. Not elasticity at all
3. The material ( the film ) wasn't as elastic as we thought . Maybe because of the HDPE HMW raw material we used.
Could anyone help? Any ideas how we can fix these problems.
Thank you.
