SABIC LLDPE 920NE is introduced into monolayer and three-layer coextrusion lines as a sealant or core resin with a nominal density of 0.920 g/cm³ under ISO 1183-1:2019 and a melt flow rate centred near 1.0 g/10 min under ISO 1133-1:2022. In food-contact packaging, formulation ratios are governed by seal initiation temperature, dart impact energy, and coefficient of friction rather than by filler loading: a three-layer bread bag construction typically runs 60–80 wt% LLDPE 920NE in the sealant skin, 20–40 wt% of a high-pressure LDPE grade with melt flow rate 0.3–0.8 g/10 min in the core, and a slip or antiblock masterbatch at 0.5–1.5 wt% where surface properties are measured under ISO 8295:1995. The downstream production process is blown film extrusion on a grooved-feed single-screw extruder with L/D 30:1, die diameter 250–400 mm, die gap 1.8–2.2 mm, blow-up ratio 2.0:1–2.5:1, melt temperature 190–215 °C, and frost line height held at 8–12 die diameters to balance bubble stability against crystallinity and haze. Regulatory compliance is anchored to FDA 21 CFR 177.1520(c) for olefin polymers in contact with food and EU Regulation 10/2011 with an overall migration limit of 10 mg/dm²; mechanical acceptance is verified under ASTM D882-18 for tensile, ASTM D1922-15 for Elmendorf tear, and ASTM D1709-16a Method A for dart impact. Terminal product types include frozen vegetable pouches, bread bags, produce bags, and ice bags in thickness ranges from 20 µm to 80 µm. Melt temperatures exceeding 220 °C increase gel count probability and reduce dart impact energy, while temperatures below 185 °C elevate melt pressure and gauge variation on L/D 30:1 extruders.
At cast stretch film line speeds between 400 m/min and 800 m/min, the controlling constraints shift from melt strength to gauge uniformity, chill-roll release, and cling-force retention across the web. SABIC LLDPE 920NE is dosed at 92–98 wt% in machine-grade pallet wrap, with 2–8 wt% of a low-density polyolefin plastomer or hydrogenated hydrocarbon tackifier; the tackifying fraction is adjusted upward when cling force measured under ASTM D5458-18 drops below the converter specification. The converting line is a cast film unit equipped with a T-slot die of width 1.2–3.5 m, die gap 0.8–1.5 mm, melt temperature 240–290 °C, and chill-roll temperature 12–25 °C; a vacuum box and air knife are positioned to pin the melt curtain and reduce edge neck-in at high line speed. Mechanical validation uses ASTM D5748-19 for stretch film puncture resistance, ASTM D882-18 for tensile, and ISO 527-3:2018 for film tensile properties; for food-wrap variants likely to contact fatty food surfaces, migration compliance follows FDA 21 CFR 177.1520 and EU Regulation 10/2011. Terminal product types include hand pallet wrap of 12–23 µm, machine pallet wrap of 15–35 µm, and pre-stretched pallet wrap with pre-stretch ratios between 60% and 250%. Chill-roll temperatures above 25 °C increase cling transfer to idler rolls, while temperatures below 12 °C can create condensation and local gauge banding.
In silage bale wrap and agricultural covers, the film is subjected to stalk puncture, prolonged UV exposure, and low-temperature flexing, so the formulation shifts toward stabilization and dart impact energy rather than optical enhancement. For a three-layer silage film structure, the outer layers are produced with 85–95 wt% SABIC LLDPE 920NE and 5–15 wt% of a UV-stabilized LDPE or HDPE carrier; a hindered amine light stabilizer masterbatch is metered at 0.2–0.6 wt% of total polymer mass, with a UV absorber often included at 0.1–0.3 wt%. The downstream conversion process is tubular coextruded blown film using a die gap of 2.0–2.5 mm, blow-up ratio 2.2:1–2.8:1, melt temperature 190–220 °C, and a high-stalk bubble geometry that maintains machine-direction orientation and puncture energy; the frost line is lowered to 6–10 die diameters because stabilizer packages alter the crystallization rate at the bubble surface. Mechanical validation is based on ISO 527-3:2018 for tensile, ASTM D5748-19 for protrusion puncture resistance, and ISO 4892-2:2013 for accelerated weathering; agricultural thermoplastic film performance is assessed under EN 13206:2017 where coverage, light transmission, and service life criteria are specified. Terminal product types include silage bale wrap, silage bags, temporary grain storage covers, and greenhouse cladding. Pigment and stabilizer packages above 1.0 wt% can accumulate at the die lip during multi-day extrusion runs, requiring melt filtration or periodic die cleaning.
Extrusion coating of paper and aluminium foil substrates with SABIC LLDPE 920NE moves the melt temperature window upward from blown film practice because draw-down, adhesion, and oxidation must be balanced at the die exit. The resin is applied neat at 100 wt% or let down at 80–90 wt% with a high-draw LDPE coating grade at 10–20 wt%; when aluminium foil adhesion is required, an anhydride-modified tie resin is introduced as a separate coextruded layer rather than as a dry blend. The downstream operation is extrusion coating on a single-screw extruder with L/D 30:1, die gap 0.5–1.0 mm, melt temperature 285–320 °C, coat weight 10–30 g/m², chill-roll temperature 12–20 °C, and line speed 100–300 m/min; inline corona treatment at 2–5 kW raises surface energy for subsequent printing or lamination. For food laminates, compliance follows FDA 21 CFR 177.1520 and EU Regulation 10/2011, with seal strength verified under ASTM F88/F88M-21 and coefficient of friction under ISO 8295:1995. Terminal product types include paper-plastic industrial sacks, foil-based food pouches, liquid packaging sachets, and medical device header pouches. Melt temperatures below 285 °C reduce draw-down stability and melt adhesion, while temperatures exceeding 330 °C increase oxidative gel formation and off-odour.
Free shrink in collation bundling film is controlled not by the LLDPE fraction alone but by the strain-hardening response of the low-density phase and the double-bubble orientation temperature. SABIC LLDPE 920NE is dosed at 70–85 wt% with 15–30 wt% of a high-pressure LDPE grade of 0.923–0.925 g/cm³ density and 0.3–0.7 g/10 min melt flow rate; the LLDPE fraction supplies dart impact energy and seal integrity, while the LDPE fraction reduces shrink force to prevent bottle deformation during bundling. The converting line is a double-bubble tubular extrusion with die gap 1.6–2.0 mm, blow-up ratio 2.0:1–2.3:1, melt temperature 190–205 °C, and second-bubble orientation at 95–115 °C. Shrinkage is quantified under ASTM D2732-20 after 10 s immersion in a 150 °C oil bath; optical characteristics are measured under ASTM D2457-21 for gloss and ASTM D1746-15 for transparency. Terminal product types include bottle multipack sleeves, can bundling film, and promotional box overwrap. Orientation temperatures below 95 °C produce freeze-off at nip rolls, while temperatures above 115 °C reduce shrink force below bundling requirements.
For refuse liners, builders film, and industrial liners, the resin must tolerate addition of post-industrial regranulate without sacrificing tear propagation resistance at reduced gauge. A typical extrusion blend contains 80–90 wt% SABIC LLDPE 920NE and 10–20 wt% post-industrial recycled LLDPE or LDPE regranulate; the upper recycled fraction is set by screen pressure rise and gel count rather than by melt flow ratio. The converting line is a monolayer or two-layer blown film extruder with L/D 30:1 grooved-barrel screw, screen pack 60/80/100 mesh, die gap 1.8–2.4 mm, blow-up ratio 1.8:1–2.5:1, melt temperature 190–220 °C, and air-ring internal bubble cooling. Physical property verification uses ASTM D882-18 for tensile, ASTM D1922-15 for Elmendorf tear, ASTM D1709-16a Method A for dart impact, and ASTM E96/E96M-22 for water vapour transmission where construction vapour retarder performance is specified. Terminal product types include institutional can liners, builders film, temporary protective sheeting, and industrial drum liners. Recycled content above 20 wt% may increase filter pressure rise and reduce dart impact below lot-release limits; gel counts above converter limits appear as visual defects in thin-gauge sections.

SABIC LLDPE 920NE is supplied as a butene-linear low-density polyethylene pellet with a nominal density of 0.920 g/cm³ when measured according to ISO 1183-1:2019 and a melt flow rate of 2.0 g/10 min at 190 °C/2.16 kg when tested per ISO 1133-1:2022. The material is classified within the linear low-density polyethylene range because its density remains below 0.930 g/cm³. Unlike high-pressure low-density polyethylene manufactured by free-radical polymerisation in tubular or autoclave reactors, SABIC LLDPE 920NE has a predominantly linear backbone with short-chain branches introduced by butene comonomer. This structural difference reduces crystalline order and lowers the melting peak into the typical LLDPE range of 120 °C to 124 °C as determined by differential scanning calorimetry per ISO 11357-3:2018. The reduction in crystallinity relative to high-density homopolymers lowers flexural modulus and increases the compliance of thin-gauge films. As a pelletised resin, the grade is intended for blown film extrusion and for cast film lines where a balance of draw-down, seal performance, and dart impact is required. The product does not require predrying under normal indoor storage conditions at relative humidity below 60%; if cold pellets are moved into a warm, humid production area, surface condensation should be eliminated before the material enters the extruder throat.
Butene comonomer produces short-chain branches that disrupt polyethylene crystallisation. At a density of 0.920 g/cm³, the crystalline fraction is sufficiently low to lower seal initiation temperature relative to higher-density LLDPE grades. Manufacturer-published seal initiation data for 25 µm blown film are typically reported between 95 °C and 105 °C, although published data for this specific film configuration is limited and the curve is sensitive to dwell time, jaw pressure, and seal bar geometry evaluated under ASTM F2029-16. In tensile testing of 25 µm film according to ISO 527-3:2018, the yield strength is typically observed in the range of 11 MPa to 13 MPa in the machine direction and 10 MPa to 12 MPa in the transverse direction. Dart drop impact at F50, tested per ASTM D1709-15 Method A, is commonly reported near 100 g for 25 µm film; lower-density grades in the 0.918 g/cm³ class may produce slightly higher impact values at the same thickness, while higher-density 0.926 g/cm³ hexene grades generally produce higher dart values but require higher seal initiation temperatures. The branched architecture also influences optical performance: haze values for 25 µm films generally remain in the range of 12% to 18% per ASTM D1003-21, depending on frost line height and die gap.
On air-cooled blown film towers, processing stability for SABIC LLDPE 920NE depends on the interaction between die gap, blow-up ratio, and frost line height. A die gap between 1.2 mm and 2.5 mm is suitable for monolayer lines; thicker die gaps reduce shear rate and preserve dart impact, while narrower gaps improve clarity and reduce resin consumption per tonne of film. Blow-up ratios between 2.0:1 and 3.0:1 are processable. Melt temperature at the die is normally maintained between 190 °C and 230 °C. Sustained operation above 250 °C increases the rate of thermo-oxidative degradation, as evidenced by gel formation in the film and discolouration of the melt stream. Operation below 180 °C may raise die pressure and produce sharkskin melt fracture, particularly on high-output lines with die gaps below 1.5 mm. The linear molecular structure of LLDPE generates less shear thinning than high-pressure LDPE; therefore, extruder motor load and head pressure may be higher at equivalent output. Single-screw extruders with L/D 30:1 and barrier-flight screws with mixing elements are recommended for homogenisation when 920NE is blended with high-pressure LDPE or colour masterbatch. Blending up to 20 wt% high-pressure LDPE improves bubble stability and increases melt strength; this addition also modifies haze and dart impact and should be revalidated against the applicable film specification. Batch-to-batch variation in comonomer distribution can shift seal initiation temperature by ±5 °C and alter dart impact by ±10% on production-scale lines, so statistical process control on the extruder barrel profile is necessary when downgauging below 25 µm.
Bubble stability in SABIC LLDPE 920NE is influenced more strongly by die geometry and cooling-air control than by melt elasticity alone. The frost line height should be established between 2 and 5 die diameters for thinner films and raised when film clarity becomes a secondary requirement to impact strength. Low frost line heights reduce crystalline orientation but can increase film blocking if the material contains no antiblock additive. When the frost line is positioned too high, the formed film develops higher machine-direction orientation and may exhibit imbalanced tear strength. Air rings with dual-lip cooling and internal bubble cooling equipment improve output consistency on high-throughput towers. Because 920NE is a butene-copolymer LLDPE, its lower melt strength relative to high-pressure LDPE makes the bubble more sensitive to sudden changes in internal air pressure; die-insert adjustments or air-ring pressure corrections should be made gradually to avoid gauge variation.
On high-speed monolayer lines operating with die gaps below 1.5 mm, the melt flow rate of 2.0 g/10 min in SABIC LLDPE 920NE offers lower extruder backpressure than 0.5 g/10 min or 1.0 g/10 min LLDPE grades. This difference permits higher screw speeds before reaching the maximum drive amperage or before melt pressure exceeds the safety limits of the die. However, a higher melt flow rate also reduces melt strength and bubble stability at low frost line heights. Processors using narrow die gaps report that barrel temperature profiles should be kept flat between 180 °C and 210 °C, with the die and mandrel heated 10 °C to 20 °C above the barrel profile to prevent premature freeze-off of the melt at the die lips. The combination of narrow die gap and high blow-up ratio can generate shear rates above 1000 s⁻¹; under these conditions, the surface melt may exhibit sharkskin unless the die exit is radiused and maintained free of degraded polymer deposits. Compared with lower melt flow rate grades, 920NE can reduce backpressure by approximately 15% to 25% on a 65 mm single-screw extruder at constant output; published data for this specific configuration is limited, and measured differences depend on screw design and temperature profile. Where maximum dart impact is more important than throughput, a wider die gap of 2.0 mm to 2.5 mm is preferred because it reduces molecular orientation in the film.
Food-packaging converters incorporate SABIC LLDPE 920NE in monolayer and coextruded film structures where low seal initiation temperature and downgauging capability are critical. In vertical form-fill-seal packaging, the resin enables shorter dwell times at the seal jaws, which can increase cycle rate. In lamination films, 920NE is used in the sealant layer because its density and comonomer type contribute to seal integrity at temperatures below those required by higher-density grades. Agricultural films and surface protective films also use this grade; however, the base resin is not formulated with ultraviolet stabilisers or anti-fog additives for outdoor service. Those additives must be introduced as masterbatch at the extruder throat. For food-contact use, compliance is assessed under European Regulation (EU) No 10/2011 and under U.S. FDA 21 CFR 177.1520(c)(3.1a) for olefin polymers. Overall migration testing is conducted according to EN 1186-1:2002 or subsequent food simulant protocols; specific migration limits apply to any additives present in the batch. The supplier's statement of compliance should be obtained for each production lot. The resin is also assessed under REACH Regulation (EC) No 1907/2006 and contains no substance of very high concern above the 0.1 wt% threshold according to the current safety data sheet. Restriction of hazardous substances compliance is governed by Directive 2011/65/EU for electrical and electronic equipment applications, which is not relevant to most packaging films but is documented for industrial customers.

Compared with high-pressure LDPE, SABIC LLDPE 920NE provides higher tensile strength at break and higher elongation at break when tested per ISO 527-3:2018, which supports downgauging of sealant webs. The melt strength is lower than high-pressure LDPE, so the bubble requires closer control of internal air pressure and frost line height. Compared with HDPE, the 0.920 g/cm³ density reduces flexural modulus and water vapour barrier; films made from 920NE transmit water vapour more readily than HDPE films of the same thickness, so barrier-specific packaging requiring moisture protection should be structured with HDPE or EVOH layers rather than relying on this resin alone. Within the LLDPE class, hexene and octene grades produce longer short-chain branches that resist dart impact propagation more effectively than butene grades at equal density and melt flow rate. The butene chemistry of 920NE typically yields a lower seal initiation temperature than higher-density grades but does not match the dart impact resistance of a 0.926 g/cm³ hexene film grade. The material is therefore specified when seal economics and downgauging outweigh ultimate puncture resistance. When converters require improved optics, a blend of 920NE with high-pressure LDPE or metallocene LLDPE may be processed, but the blend ratio must be revalidated for seal strength per ASTM F88/F88M-21 and for dart impact per ASTM D1709-15 Method A.
Handling and storage follow standard polyethylene practice. The pellets are hydrophobic; however, surface moisture from condensation on cold pellets entering a warm humid plant can generate splay and bubbles in the extrudate, so storage areas should be kept below 60% relative humidity or pellets should be allowed to reach ambient temperature before opening sealed containers. Avoid processing above 250 °C for extended residence times; prolonged exposure at elevated melt temperature promotes gel formation and photochemical degradation in downstream film. The resin is not compatible with strong oxidising acids, halogens, or aromatic hydrocarbon solvents at elevated temperatures, and equipment should be purged with high-pressure LDPE or a commercial purging compound when transitioning from polar polymers such as polyamide or EVOH. In coextruded structures, direct contact with EVOH without an adhesive tie layer is not recommended because interfacial adhesion is insufficient.
