Typical Applications
Shopping and T-Shirt Bags
Thin films requiring stable extrusion, stiffness and practical strength.
Industrial Liners
Liners and protective films selected for puncture, tear and thickness targets.
Heavy-Duty Sacks
Film systems where HDPE may be used alone or in blends for stiffness and load performance.
Blending with LDPE or LLDPE
Blends used to adjust stiffness, sealing, drawdown and mechanical properties.
Grade Selection Factors
The following factors are application references, not guaranteed specifications. Final selection must be confirmed using the current producer TDS, COA and customer requirements.
| Selection Item | What to Confirm |
|---|---|
| Extrusion process | Confirm blown-film line, die size, output and cooling conditions. |
| Blend formulation | State whether the grade is used alone or with LDPE/LLDPE. |
| Film mechanics | Define tear, puncture, stiffness and thickness requirements. |
| Additives | Confirm slip, antiblock, color and processing-aid requirements. |
Information Needed for Quotation
Film type, current formulation, current grade, thickness, blow-up ratio, line output, mechanical targets, additive requirement, quantity and destination port.
Frequently Asked Questions
Can HDPE film grade be blended with LLDPE?
Yes. Blends are common, but the correct ratio depends on film and processing targets.
Is MFI alone enough for grade selection?
No. Molecular structure, density, processing behavior and film properties also matter.
Can you review a current formulation?
Yes. Share the grades, blend ratio and finished-film requirements.
