HPR 1018HA Metallocene LLDPE Resin for Heavy and Flexible Packaging Film

The primary application for HPR 1018HA is heavy-duty packaging film — bags and liners used to carry agricultural inputs, industrial granules, construction materials, and bulk food ingredients. The dart drop impact value of ≥300g at 0.025mm film thickness reflects the energy absorption capacity these end-uses demand. A bag handling a 25 kg load of fertilizer or polymer resin pellets needs to survive drop and abrasion events during palletizing and storage, and the falling weight impact specification directly addresses that requirement.

Flexible packaging film is the second major end-use category. Shrink films, stretch wrap, and multilayer lamination structures benefit from the elongation-at-break values above 300%, which allow film to deform and conform without tearing under packaging line tension or load. In these applications, the metallocene architecture of HPR 1018HA delivers more consistent film properties across the web width than Ziegler-Natta LLDPE grades at comparable melt flow, because the narrower molecular weight distribution reduces variation in crystallization and orientation behavior during film blowing.

The controlled fish eye specification — ≤8 defects per 1520cm² at 0.8mm — supports end-uses where surface quality affects downstream converting steps such as printing, lamination, or heat sealing. Packaging film that carries printed graphics or forms part of a laminated pouch structure requires a gel-clean surface to maintain bond integrity and print registration.

BASTONE Petrochem sources HPR 1018HA through its PetroChina distribution channel. Dushanzi Petrochemical's 600,000-ton/year full-density polyethylene unit is one of the larger PE production assets in China, and production-allocated supply access means buyers are not competing for spot volumes when demand spikes. For procurement teams operating on quarterly or annual contracts, supply reliability across the full delivery period matters as much as the product specification itself.

Batch-traceable COA documentation comes with every HPR 1018HA shipment BASTONE handles. Buyers can verify incoming material against the PetroChina datasheet parameters — MFR, density, tensile properties, fish eye counts, dart impact — without relying solely on incoming QC testing. BASTONE supports third-party inspection arrangements at origin for buyers who require pre-shipment verification.

The BASTONE group's R&D background in polymer chemistry gives buyers technical support that extends beyond order tracking. When procurement teams are evaluating HPR 1018HA against alternative mLLDPE grades — whether comparing to OQ's Luban HPR-1018HA from Oman or ExxonMobil's Exceed-series — BASTONE's technical team can work through grade selection based on processing equipment specifications and film performance targets, rather than leaving the comparison entirely to the buyer's internal R&D function.
