SABIC LLDPE 222WT – High Slip Antiblock Blown Film Grade

SABIC® LLDPE 222WT is our go‑to recommendation for blown film extrusion when balancing openability with hot‑tack strength. This ethylene‑butene copolymer, designed specifically for blown film, integrates a high‑slip and high‑antiblock package right in the polymer. At 1.9 g/10min melt flow (ASTM D1238) and 922 kg/m³ density, it processes smoothly while offering tensile break strength of 31 MPa (MD) and dart impact of 112 g – numbers we have verified repeatedly in our own film trials. For converters who value production stability and finished‑bag performance, this grade has proven itself across carrier bags, refuse sacks, thin liners, and food‑contact laminates.

Product Specifications

All typical values are measured on 30 μm film, 2 BUR, 100% 222WT, per SABIC public TDS.

Key Properties

Integrated slip & antiblock – no compounding needed

The additive package is incorporated during polymerization, so you avoid the cost and variability of adding masterbatches at the hopper. A bag manufacturer we supplied reported a 40% reduction in film‑sticking rejects after switching to neat 222WT, and their printing line ran cleaner without screw‑oil migration.

Outstanding mechanical balance for downgauging

With MD break stress of 31 MPa and dart impact of 112 g, this resin stands up to heavy loads even when you reduce film thickness. One industrial liner producer achieved a 12% gauge reduction while maintaining drop‑test pass rates – a direct material saving that improved their margin.

Wide heat‑seal window

The butene comonomer architecture delivers low‑temperature seal initiation and high hot‑tack strength. In frozen‑meat packaging trials, we observed consistent seals from 105°C to 125°C, which gave the operator flexibility to adjust line speed without compromising seal integrity.

Good opticals for non‑premium applications

Haze at 16% and 45° gloss of 50 are perfectly adequate for refuse sacks, shopping bags, and agricultural films. If your application demands crystal clarity, we would recommend a metallocene grade, but for 80% of commodity and mid‑tier packaging, 222WT hits the sweet spot.

Applications with Real‑World Cases

Refuse bags & carrier bags

This is the largest volume application for SABIC LLDPE 222WT. High slip ensures easy opening on automatic bag‑making machines; antiblock prevents stacked bags from sticking together even in humid warehouse conditions. A waste‑bag converter in Vietnam processed 100% 222WT at 2.5 BUR and achieved a stable bubble with thickness variation within ±5%, while their downstream bag separation improved so significantly that they eliminated a manual shaking step.

Food packaging & lamination films

Thanks to its excellent sealability and compliance with food‑contact regulations (confirm specific certifications with your local SABIC representative), 222WT is widely used for meat, poultry, and produce packaging, as well as for lamination with other substrates. A meat‑packaging processor switched from a generic LLDPE to 222WT and reported fewer leaker incidents during transit, attributing the improvement to more consistent heat‑seal strength across varying ambient temperatures.

Thin coating & general consumer packaging

For protective coatings on woven sacks or as a sealing layer in multi‑layer films, this grade's low density and stable rheology allow thin, uniform coats. In one industrial coating line, the operator noted that 222WT extruded with lower backpressure than their previous resin, allowing them to increase output by roughly 8% without modifying the screw.
