PetroChina LLDPE DFDA-7042 — Linear Low Density Polyethylene Resin for Blown Film

General Information

Pellet Quality Properties

Full mechanical and optical test data — including MFR, density, tensile properties, elongation, haze, and falling weight impact — are available in BASTONE's Technical Data Sheet. Contact the BASTONE team to request the complete TDS for DFDA-7042.

Packaging film is the primary outlet for DFDA-7042. Blown film converters supplying flexible packaging to food, consumer goods, and industrial sectors depend on LLDPE's puncture resistance and tensile toughness — properties that allow film producers to run at thinner gauges than PE-LD while maintaining the structural integrity that end-users require. DFDA-7042's pellet cleanliness specifications directly support consistent optical quality in clear packaging film applications where gel count affects customer acceptance.

Agricultural film represents a significant volume application, particularly in markets across China, Southeast Asia, and Central Asia where mulch film and greenhouse covering are produced at high tonnage. Agricultural film runs in environments that subject the polymer to mechanical stress, soil contact, and UV exposure. The 1-butene comonomer chemistry in DFDA-7042 provides the elongation at break and tear resistance needed to survive field application without premature failure — an important consideration for film producers supplying large-scale agricultural operations where film replacement mid-season is operationally disruptive.

BASTONE Petrochem holds listed distributor status with SINOPEC and distributes products from China's top three petrochemical producers, giving the commercial team direct allocation access rather than reliance on spot-market inventory. Each export shipment of DFDA-7042 includes a Certificate of Analysis traceable to the originating production batch, SGS or equivalent third-party inspection on request, and a complete export documentation package: commercial invoice, packing list, bill of lading, and certificate of origin. Buyers operating in import-sensitive markets or managing letters of credit can work with BASTONE's trade team to align documentation requirements before the order is confirmed.

The BASTONE parent group operates four production sites and an R&D center focused on specialty chemical manufacturing — a technical foundation that pure trading houses do not have. When a film converter needs grade equivalency guidance between a domestic resin source and an imported LLDPE, or requires processing condition recommendations for a new extruder configuration, BASTONE's team can engage directly at a technical level rather than routing the question through a manufacturer's commercial contact.

Export operations run through Zhejiang Bastone Technology Co., Ltd, supporting flexible trade terms including FOB Ningbo and FOB Shanghai, as well as CIF and CFR to major destination ports. Container loading specifications, fumigation certificates, and IMO documentation are coordinated in-house, reducing the logistics overhead for importers managing multi-origin chemical supply chains.
