LLDPE Heavy Duty Film Grade Granules

The final performance depends on the resin’s density, MFR, molecular structure and comonomer composition, as well as the processing conditions used during film extrusion. Typical applications include heavy-duty industrial bags, agricultural and construction films, industrial liners, fertilizer and chemical packaging, waste collection bags and other demanding packaging products. In these applications, resistance to puncture, tear propagation, impact and stretching is often more important than maximum optical clarity. Heavy Duty LLDPE can be processed using blown film extrusion and may also be combined with LDPE, mLLDPE or other polyethylene materials to achieve a specific balance of strength, flexibility, sealability and processing stability. Film manufacturers should consider the required thickness, bag dimensions, filling weight, operating environment and extrusion equipment when selecting a suitable grade. Choosing the correct MFR and molecular structure is particularly important for maintaining stable extrusion and achieving consistent film thickness in industrial production.

LLDPE Heavy Duty Film Grade is normally supplied in sealed polymer bags designed to keep the granules clean and protected throughout storage and international transportation. Depending on the supplier and order volume, 25 kg bags and larger jumbo bags can be used for commercial shipments. For export transactions, proper palletizing and protective wrapping can further reduce the risk of bag damage and material contamination during handling and transportation. Buyers should request the TDS and COA for the exact grade and batch, paying particular attention to MFR, density and mechanical properties relevant to the intended heavy-duty film application.
