LDPE regains rare premium over mLLDPE in Italy as supply tightness reshapes pricing hierarchy

Italy’s PE markets have witnessed an unusual price structure, as LDPE sharply widened its premium over mLLDPE, reversing a relationship that typically favours metallocene grades. The disparity is primarily supply-driven, with LDPE availability tightening, allowing producers to push through hikes, while mLLDPE prices remained capped by comfortable supply conditions.

From May to November 2025, LDPE prices in Italy mostly traded below mLLDPE C6, reflecting weak demand and broad-based pressure across the PE complex. This dynamic shifted in early December, when LDPE availability tightened, enabling producers to lift prices more aggressively. Since then, LDPE has consistently traded at a premium over mLLDPE, with the gap recently approaching €100/ton—a rare occurrence in Europe, where LDPE typically trades at a discount. The two products are currently trading at par in West Europe, as a side note.

Supply tightness allows LDPE to absorb cost pressure and more

LDPE posted notable hikes despite stable to softer ethylene settlements in December and January. With February calling for a firmer monomer outcome, LDPE has emerged as the grade most capable of absorbing not only feedstock increases but also additional margin recovery, largely thanks to tighter supply conditions.

According to ChemOrbis Price Index, spot LDPE film prices in both Italy and West Europe posted cumulative increases of €100-140/ton since their reversal in late 2025.

In contrast, mLLDPE supply is described as comfortable, limiting producers’ ability to push through similar hikes. Despite the stable to slightly firmer trend, mLLDPE C6 prices are at their lowest levels since mid-to-late 2020. As a result, LDPE prices rose more sharply, while mLLDPE lagged, reinforcing the premium carried by LDPE.



Why mLLDPE usually trades at a premium?

Under normal market conditions, mLLDPE typically commands a premium over LDPE due to its superior mechanical properties, downgauging potential and wider use in high-performance film applications, which support stronger value perception and pricing power.

Wide premium triggers substitution to linear grades

Early February LDPE sales for non-European origins started to be closed at higher levels, with buyers accepting levels around €1100/ton FD, underscoring LDPE’s relative pricing power.

Meanwhile, mLLDPE prices have remained at unusually low levels, consistently trading below LDPE over the past two months, amid comfortable availability, while LLDPE has remained under pressure from ample imports, particularly in Italy, where inflows continue to cap upside potential. These levels encouraged substitution, with some buyers opting for mLLDPE or LLDPE instead of LDPE where technical specifications allow—a trend that could soften LDPE demand in the months ahead if the price gap persists.

Looking ahead, the LDPE–mLLDPE gap remains largely supply-driven. As long as LDPE availability stays tight, producers are expected to defend higher levels, while comfortable linear supplies have so far restrained price gains. Although the current premium may narrow, the episode underscores how supply imbalances—rather than demand alone—can temporarily overturn Europe’s traditional PE pricing hierarchy.

Import flows may tighten, opening room for linear-grade corrections

Beyond LDPE, other PE grades have so far been comfortably supplied, mainly due to steady imports. However, traders are increasingly flagging a more cautious supply outlook, citing reduced inventories and growing concerns over potential import delays from the US amid the freeze, alongside outages in Saudi Arabia and Egypt.

While these factors have yet to translate into immediate price gains, they are starting to erode the sense of comfort around LLDPE and mLLDPE availability. With import flows potentially tightening, linear grades may find support for upward corrections, particularly for mLLDPE, which is widely seen as undervalued relative to LDPE under the current structure. Market players also caution that HDPE could also face tightening conditions in the near term, driven by planned or unplanned supply disruptions.
