LL0209AA is manufactured at PetroChina’s Dushanzi facility in Xinjiang using licensed BP gas phase fluidized bed technology. The process combines polymerization-grade ethylene with 1-butene as a comonomer and uses hydrogen as a molecular weight regulator under titanium-based catalysts. After polymerization, the powder goes through extraction, separation, and pelletization \u2014 producing clean, natural-colored granules that meet the Q\/SY DS035-2000 execution standard.<\/p>\n
The grade carries a melt flow rate of 1.0 g\/10 min at 2.16 kg load, placing it in the standard processing window for blown film lines. Density sits at 0.920 g\/cm\u00b3, consistent with a butene-comonomer LLDPE positioned for general film applications. At that MFR, processors can expect stable bubble formation and predictable draw-down behavior on conventional single-screw blown film equipment.<\/p>\n
Film performance data from the datasheet shows tensile stress at break of 40 MPa (MD) and 36 MPa (TD), with elongation at break reaching 700% and 900% in the machine and transverse directions respectively. Falling weight impact strength on 0.030 mm film measures 80 g. Haze tests at 21%, a figure that supports adequate clarity for food and produce packaging where visible content identification matters. Fish eye counts are tightly controlled \u2014 a maximum of 1 per 1520 cm\u00b2 at 0.8 mm and 7 per 1520 cm\u00b2 at 0.4 mm \u2014 which reduces film defects in high-speed packaging operations.<\/p>\n
Anti-blockage performance is rated as easy to peel, which is important in high-speed packaging operations where film sheets need to separate cleanly on automated filling and sealing machinery.<\/p>\n
BASTONE sources LL0209AA through its established trading relationship with PetroChina, one of China’s top three petrochemical producers. All shipments are accompanied by full certificate of analysis documentation traceable to the production batch, with test results aligned to the Q\/SY DS035-2000 standard. Buyers can request pre-shipment samples before committing to container-volume orders.<\/p>","protected":false},"excerpt":{"rendered":"
