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

HPR 1018HA is a metallocene linear low-density polyethylene (mLLDPE) resin produced by PetroChina Dushanzi Petrochemical Company using the Unipol gas-phase fluidized bed process, with hexene-1 as comonomer and metallocene catalysts.

With a melt flow rate of 1.0 g/10min and density of 0.920 g/cm³, the grade is designed for blown film extrusion and targets heavy-duty and flexible packaging film applications where tensile strength, elongation, and dart impact resistance are deciding factors.

Description

HPR 1018HA belongs to the mLLDPE category — a class of polyethylene where metallocene catalyst technology produces a narrower molecular weight distribution compared to conventional Ziegler-Natta LLDPE grades. PetroChina Dushanzi Petrochemical manufactures HPR 1018HA at its 600,000-ton/year full-density polyethylene unit in Xinjiang, using polymerization-grade ethylene as the primary feedstock and hexene-1 as the comonomer. Hexene-1 incorporation controls short-chain branching distribution, which is the structural lever that gives mLLDPE its mechanical performance advantage over butene-based LLDPE at equivalent density.

The melt flow rate of 1.0 ± 0.30 g/10min at 2.16 kg load places HPR 1018HA in a processability range suited to blown film lines. Density at 0.920 ± 0.002 g/cm³ falls within the standard LLDPE range, but the tighter comonomer uniformity from metallocene catalysis translates into better mechanical performance per unit thickness — allowing converters to downgauge film without sacrificing puncture or tear resistance.

Mechanical data from the PetroChina datasheet confirms tensile strength at ≥14 MPa, tensile yield stress at ≥9.5 MPa, and fracture nominal strain at ≥300%. Dart drop impact on 0.025mm film reaches ≥300g per GB/T 9639.1-2008, which directly reflects puncture resistance under load in packaging end-use. Fish eye counts are controlled to ≤8 defects per 1520cm² at 0.8mm and ≤20 at 0.4mm — relevant for optical uniformity and downstream printability on converted film.

Processing aids are incorporated at the production stage, so HPR 1018HA arrives formulated for direct use on standard blown film extrusion equipment. Converters do not need to add separate slip or anti-block packages, which simplifies the production setup and reduces formulation variability between batches.

BASTONE distributes HPR 1018HA from PetroChina supply chains with full certificate of analysis documentation traceable to the specific production batch at Dushanzi. Each COA covers all technical indicators against the datasheet parameters, including MFR, density, tensile properties, fish eye counts, and dart impact — giving buyers a direct verification baseline at goods receipt.

Applications

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.

Why Source Through BASTONE

Palletized HPR 1018HA shipment

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.
