Applications
Heat Shrink Film
The 0.3 g/10min MFR enables blown film processors to run at standard production speeds while maintaining tight gauge uniformity. The thermal shrinkage performance of the grade — driven by the controlled branching structure inherent to tubular reactor LDPE — suits multi-layer shrink bundling applications in beverage, industrial goods, and retail secondary packaging, where consistent shrink force and clarity retention after tunnel exposure matter.
FFS Heavy Packaging Bags (Form-Fill-Seal)
FFS bag production demands a resin that combines film strength, sealability, and toughness under drop and puncture load. LDPE 1810D's elongation at break of 500% and falling weight impact resistance of 160 g at 30μm deliver the mechanical profile needed for heavy-duty FFS bags carrying bulk materials — fertilizers, polymer pellets, powders — where the seal integrity and bag body must survive drop and stacking conditions in warehouse and transit environments.
Pipeline Coating
In extrusion coating onto steel pipe, LDPE functions as a corrosion-barrier layer bonded to the pipe surface. The melt temperature window of 190–205°C and the grade's tractility allow consistent extrusion over large-diameter pipe substrates. The absence of additives in the base resin also simplifies adhesion layer formulation for processors using multi-layer coating systems.
Coaxial Cable Insulation
Cable insulation extrusion demands low contamination levels and consistent pellet geometry to prevent surface defects in the extruded layer. LDPE 1810D's pellet appearance specification — tightly limiting colored particles, angle hair, and pellet size deviants — reduces the risk of process interruptions and insulation layer defects during high-speed cable extrusion.
Why Source Through BASTONE
BASTONE Petrochem holds authorized distributor status for PetroChina product lines, which means contracted allocation — not opportunistic spot purchasing — backs every supply commitment. Buyers operating on annual volume contracts or long-term supply agreements get predictable access to the grade without exposure to the availability swings that characterize spot-market sourcing.
Every LDPE 1810D shipment supplied through BASTONE carries a manufacturer-issued COA from PetroChina Lanzhou Petrochemical, tested against Q/SY 1349-2014 and traceable to the specific production batch. BASTONE's export entity — Zhejiang Bastone Technology Co., Ltd — manages the full documentation package: customs declaration, packing lists, bills of lading, and any destination-market compliance certificates buyers require.
The BASTONE group operates four production sites and a dedicated R&D center focused on specialty chemicals. Buyers evaluating grade selection — for example, assessing whether LDPE 1810D's 0.3 g/10min MFR suits a specific FFS film line configuration versus a higher-flow alternative — can access direct technical input from the group's chemistry team. A pure trading house has no equivalent resource.
Handling, Storage & Safety Guidelines
LDPE 1810D is non-hazardous in granulated form under normal handling conditions. Adequate ventilation is required in processing areas where the resin is heated above its melt temperature — thermal processing can produce low-level hydrocarbon emissions, and enclosed areas without air exchange should be avoided.
Store in a ventilated, dry, and clean warehouse with operational fire suppression systems in place. Polyethylene is a combustible solid; outdoor storage and exposure to direct sunlight, moisture, or contamination sources are not acceptable. Packaging must remain intact through storage and transit — damaged bags should be resealed promptly to prevent pellet contamination and moisture uptake that can affect processability.
For compliance documentation covering FDA, RoHS, or other destination-specific regulatory requirements, contact your BASTONE account representative to obtain the applicable records for each shipment.
