SABIC LLDPE M13024T is a metallocene-catalyzed linear low-density polyethylene with nominal density 0.913 g/cm³ (ISO 1183-1:2019) and melt flow rate 0.24 g/10 min (ISO 1133-1:2022 at 190 °C/2.16 kg). The low MFR produces higher melt pressure in blown film dies and is selected where extensional stability, dart impact resistance, and low-temperature puncture behavior outweigh melt throughput. Downstream conversion in this document is limited to documented film and lamination sectors; extrusion coating of thin webs is not specified because the high melt viscosity at the stated MFR imposes excessive motor load on high-speed extrusion coating screws, a documented operational boundary.
Industrial shipping sacks and flexible intermediate bulk container liner webs are produced from M13024T on monolayer or coextruded blown film lines with screw L/D ratios of 25:1 to 30:1, barrier screws with dispersive mixing sections, and die head pressure typically maintained between 350 bar and 450 bar. The formulation addition ratio for this sector is 80–100 wt% M13024T and 0–20 wt% high-pressure LDPE with density 0.920–0.925 g/cm³, the LDPE fraction introduced solely to raise melt strength and enlarge the stable bubble envelope at blow-up ratios of 2.0:1 to 3.2:1; a fluoropolymer processing aid is metered at 0.03–0.08 wt% to suppress melt fracture at the die lip, with the M13024T fraction adjusted to close the formulation at 100 wt%. The production process operates with extruder temperatures from 170 °C in the feed zone to 210–230 °C at the die, a die gap of 1.6–2.2 mm, and frost line height set 600–1,200 mm above the annular die; internal bubble cooling is recommended above 1,200 mm die diameter to remove the exotherm from thick-film production. Terminal finished products include gusseted heavy-duty sacks for polymer resin fillers, valve bags for cementitious powders, and tubular or sheeting FIBC inner liners with a thickness of 100–200 µm, where tear initiation resistance and seam weld strength are controlled under ISO 527-3:2018 for film tensile properties and ISO 21898:2004 for FIBC liner requirements. The resin falls under REACH Annex V polymer exemption when exported to the European Union; additive packages for UV or colour must be selected from REACH-registered masterbatch formulations.
In three-layer agricultural silage and greenhouse film production, M13024T is incorporated as the core toughness layer and, at lower addition, in the UV-stabilised outer layers. The formulation addition ratio across the entire film is 70–85 wt% M13024T; the core layer is run at 100 wt% M13024T without diluting LDPE, while each outer layer contains 15–25 wt% high-pressure LDPE and 8–12 wt% of a UV stabiliser masterbatch expressed on layer mass, the remaining fraction being M13024T. The multilayer bubble is run on coextrusion dies of 1,200–2,800 mm diameter with a layer distribution of 20/60/20 to 25/50/25 and total film thickness of 25–45 µm for silage bale wrap and 80–120 µm for silage bags. Output is controlled by frost line residence time, not by maximum screw speed; the frost line is maintained at 800–1,500 mm above the die to allow sufficient time for stress relaxation and crystallisation of the low-MFR metallocene chains, preventing poor transverse direction tear resistance after outdoor exposure. Process temperatures range from 180 °C in feed sections to 210–230 °C at the die, with external cooling air ring set to 12–18 °C and dual-lip air rings for thick films. Terminal finished product types include round bale silage stretch film, silage storage bags, and greenhouse cladding with multi-season UV stability, evaluated under EN 13207:2018 for silage films and ISO 4892-2:2013 for accelerated weathering; exposed greenhouse films also require REACH-compliant UV masterbatch components and should not be reprocessed back into food contact film without migration testing.
| Coextruded layer | Mass fraction | M13024T content | Functional additive package | Target thickness |
|---|---|---|---|---|
| Outer UV-stabilised layer | 20–25 wt% | 70–80 wt% of layer | HALS/UV masterbatch 8–12 wt%, LDPE 15–25 wt% | 5–10 µm |
| Core toughness layer | 50–60 wt% | 100 wt% | Fluoropolymer PPA 0.03–0.05 wt% | 12–25 µm |
| Inner cling layer | 20–25 wt% | 75–85 wt% of layer | Cling additive 2–4 wt%, LDPE 10–20 wt% | 5–10 µm |
Food contact flexible packaging uses M13024T as the sealant layer in form-fill-seal webs, flow-wrap films, and lamination base films, where the metallocene-catalysed molecular weight distribution lowers seal initiation temperature compared with high-pressure LDPE. The formulation addition ratio is 85–100 wt% M13024T, 0–15 wt% high-pressure LDPE for cold temperature impact modification, 1–3 wt% of a food-contact slip and antiblock masterbatch, and 0.03–0.05 wt% fluoropolymer processing aid; all additive masterbatches must be supported by EU 10/2011/EU listing, US FDA 21 CFR 177.1520(c) olefin polymer clearance, and national positive lists such as China GB 9685-2016. The blown film line runs with a die gap of 1.0–1.8 mm, blow-up ratio 2.0:1 to 2.8:1, and melt temperatures of 190–220 °C to minimise oxidative degradation products that contribute to taste and odour. The finished web thickness is 20–60 µm and the sealant layer is characterised by hot tack strength measured under ASTM F1921-12 and seal strength measured under ASTM F88/F88M-15; overall migration is tested under EN 1186-1:2002 with a limit of 10 mg/dm² for plastic food contact materials. Terminal finished product types include vertical form-fill-seal pillow pouches for frozen vegetables, flow-wrap films for bakery products, lamination base webs for snack packaging, and barrier laminates where M13024T is the inner sealant web against EVOH or polyamide barrier layers. Processing boundaries include exclusion of post-consumer recyclate in the direct food contact layer and avoidance of amine-based antifog compounds unless dual-listed for the intended food type and validated for migration under the intended temperature-time profile.
Pallet unitisation stretch hood film is converted from M13024T via high-blow-ratio blown film extrusion, where the grade’s low MFR and metallocene branching contribute to puncture resistance and elongation-at-break. The formulation addition ratio is 70–85 wt% M13024T, 15–30 wt% high-pressure LDPE to balance transverse direction tear, 0–10 wt% of a higher-density LLDPE with density 0.930–0.940 g/cm³ for those hoods requiring higher load retention, and 0.03–0.08 wt% processing aid to control die build-up at high output, with the M13024T fraction adjusted to close the formulation at 100 wt%. The film is run at a melt temperature of 210–230 °C, die gap 1.8–2.4 mm, and blow-up ratio 3.0:1 to 4.0:1 to pre-orient the film in both machine and transverse directions, with total thickness between 50 µm and 120 µm depending on pallet mass. Stretch hood machine prestretch is set at 55–70%; the film must sustain elongation without localised necking or catastrophic tear, measured under ASTM D5748-19 for puncture resistance and ASTM D5458-18 for cling stretch film peel force. Terminal finished products include tubular stretch hoods for palletised construction materials, appliance cartons, and chemical bag stacks requiring outdoor storage; the operational boundary is that high prestretch above 70% can induce localised thinning at pallet corners, so film thickness must be re-verified if pallet dimensions exceed 1.2 m × 1.1 m.
Liquid packaging lamination structures use M13024T as an extrusion-laminated or adhesive-laminated sealant web on aluminium foil or metallised polyester, provided the converter compensates for the low MFR by raising die temperature and reducing line speed. The formulation addition ratio in the sealant layer is 70–90 wt% M13024T, 10–30 wt% high-pressure LDPE for adhesion and edge sealability, and 2–5 wt% white or colour masterbatch where opacity is required, with the M13024T fraction adjusted to total 100 wt%; adhesion to aluminium foil in extrusion lamination is evaluated under ASTM D1876-08 for peel resistance, with interlaminar adhesion of 2 N/15 mm or higher required for aseptic carton structures. The production process for the sealant web is blown film extrusion at 200–220 °C, die gap 1.2–1.8 mm, and blow-up ratio 2.0:1 to 2.5:1, producing a sealant web thickness of 20–40 µm that is subsequently laminated to foil and paperboard; corona treatment to 38 dyn/cm measured under ASTM D2578-17 is required for adhesive lamination adhesion. Terminal finished product types include bag-in-box liners for liquid concentrates, condiment pouches with hot-fill requirements, and liquid detergent pouch sealant layers; compliance for direct food contact is governed by EU 10/2011/EU, FDA 21 CFR 177.1520(c), and GB 9685-2016 for additive migration. Published data for this specific low-MFR grade in extrusion lamination is limited; converters should validate line speed and interlaminar adhesion on their screw L/D before commercial runs. The grade should not be processed on high-speed extrusion coating screws with L/D below 24:1, because excessive melt pressure and shear heating can degrade the polymer and reduce seal strength.

SABIC LLDPE M13024T is a butene-based linear low-density polyethylene supplied in pellet form for cast-film and blown-film conversion. The grade is characterized by a nominal melt flow rate of 2.4 g/10 min determined at 190 °C/2.16 kg according to ISO 1133-1:2022 and a nominal density of 0.918 g/cm³ determined according to ISO 1183-1:2019. These specification points place the material in the low-density C4 LLDPE segment, where the ethylene-butene backbone provides draw-down and toughness relevant to film gauges from 8 µm to 40 µm. The pellet formulation includes an antioxidant package and, depending on the exact SABIC technical data sheet issue, a processing aid. Because additive loadings vary by production lot, food-contact compliance must be verified from the current grade-specific documentation rather than inferred from the base resin family.
In ethylene-butene LLDPE, short-chain branching is produced by incorporation of butene co-monomer; the branch length and distribution determine density, crystallinity, and tie-chain concentration. Seal initiation temperature is commonly measured on a laboratory heat sealer with flat PTFE-coated jaws according to ASTM F2029; for C4 LLDPE grades with density near 0.918 g/cm³, the seal initiation range reported in technical literature is typically 95–110 °C when tested on 25 µm cast film at 0.5 MPa jaw pressure and 0.5 s dwell time. The shorter butene branch is less efficient than a hexene branch in creating entangled tie chains, so C4 LLDPE grades generally exhibit lower dart impact values than C6 LLDPE grades of equivalent density when evaluated according to ASTM D1709-16A. In cast-film conversion, the lower melt elasticity of C4 LLDPE can delay draw resonance at high draw-down ratios. Published data for the specific seal-initiation temperature of M13024T should be confirmed from the current SABIC product data sheet, as seal response is influenced by film thickness, seal pressure, dwell time, and the presence of slip or antiblock concentrates.
On a single-screw cast-film extruder with screw diameter 75–90 mm and 30:1 L/D, a typical flat reverse barrel profile for M13024T uses rear zones at 180–190 °C, compression zones at 210–230 °C, and adapter/die zones at 235–250 °C. The melt temperature measured at the die is normally maintained between 230 °C and 250 °C. Sustained operation above 260 °C can initiate oxidative gel formation and reduce film clarity; operation below 200 °C can increase melt viscosity enough to raise extruder pressure and produce unmelts in the edge sections of the die. Die-lip fouling in C4 LLDPE is generally more pronounced than in C6 LLDPE or metallocene grades because the butene-rich low-molecular-weight fraction migrates to the lip and oxidizes during prolonged runs. If the M13024T additive package includes a fluoropolymer processing aid, the onset of sharkskin is shifted to higher shear rates, but the effect is temperature-dependent: lowering the die temperature from 250 °C to 230 °C may increase die pressure by 10–20 % and narrow the stable gauge window. Die-lip cleaning frequency on a commercial line is therefore an operational variable that depends on the presence of processing aid, melt temperature, and die gap.
Film property differentiation between M13024T and other C4 LLDPE grades depends on molecular weight distribution, comonomer distribution, and additive formulation. The grade’s nominal melt flow rate of 2.4 g/10 min is higher than fractional-melt film resins in the 0.5–1.0 g/10 min range, which reduces extruder torque and permits higher throughput in thin-gauge cast film. Compared with LDPE of equivalent melt index, M13024T shows higher tensile elongation at break and higher dart drop impact when tested according to ASTM D882-18 and ASTM D1709-16A, because the linear backbone with short-chain branching distributes stress more effectively. Tensile strain at break for C4 LLDPE films of this density class commonly exceeds 500 %. The melt strength difference is significant in blown-film operations: LDPE derives bubble stability from long-chain branching, while M13024T has lower melt tension and may require blending with 20–30 wt% LDPE to stabilize large-diameter bubbles. In cast film, the lower melt tension is not a constraint and can support draw-down to gauges below 10 µm at commercial line speeds.

Values are typical data from SABIC technical literature for unmodified compression-moulded or film specimens and are not release limits. Properties vary with specimen preparation, film gauge, and test speed. They should be verified against the current product data sheet for the specific production lot.
Differences from other LLDPE classes become measurable in Elmendorf tear, dart impact, and puncture resistance. C6 LLDPE grades of the same density and melt index usually show higher Elmendorf tear strength when measured according to ASTM D1922-15 and higher dart impact when measured according to ASTM D1709-16A, because hexene branches generate a more efficient tie-chain network. Metallocene-catalysed LLDPE grades have a narrower molecular weight distribution and a more uniform comonomer distribution; they typically deliver lower extractables, lower heat-seal initiation temperature measured by ASTM F2029, and better organoleptics than Ziegler-Natta C4 grades, but mLLDPE often exhibits higher shear viscosity and can demand more extruder torque at the same melt index. M13024T occupies the C4 segment and is therefore selected where cast-film draw-down, gauge uniformity, and material economics are weighted more heavily than maximum dart impact. In blown-film blends with LDPE, the C4 structure reduces seal initiation temperature relative to pure LDPE while retaining sufficient bubble stability when the LDPE fraction is maintained above 20 wt%.
In melt-processing terms, the C4 grade is distinguishable from C6 and metallocene LLDPE by its shear viscosity at the die lip and its melt fracture envelope. At the same melt index, C4 LLDPE tends to have a broader molecular weight distribution than metallocene-catalysed grades, which lowers the high-shear viscosity near the die lip and reduces die pressure. The broader distribution may also produce a slightly higher gel level after extended residence time above 240 °C. On a capillary rheometer using ISO 11443:2021, the flow curve of a broad-distribution C4 LLDPE typically shows a more pronounced shear-thinning slope than an mLLDPE of equal melt index. This response is measurable as a lower die pressure on cast-film lines and can be used to distinguish the grade from narrow-distribution alternatives. The same broadening, however, can reduce clarity and increase extractable levels in high-temperature food-contact film, which is why converters balance throughput against migration limits.
Replacing LDPE with C4 LLDPE changes the bubble stability envelope, frost-line height, and die pressure response. Long-chain branching in LDPE provides strain hardening that resists bubble instability under high draw; M13024T lacks that long-chain branching and therefore generates lower melt tension. On a single-screw blown-film line with die diameter 200 mm and die gap 1.5 mm, the frost-line height for M13024T is normally reduced to between 5D and 8D from the die face to stabilize the bubble, whereas LDPE may tolerate frost-line heights above 10D. A blend containing 70–80 wt% M13024T and 20–30 wt% LDPE is a common industrial route to recover bubble stability while retaining LLDPE toughness. The two polyethylenes are not fully miscible in the melt; a single-screw extruder with a low-shear screw may leave LDPE-rich domains that generate film clarity defects. A barrier screw with a Maddock mixer, or coextrusion feed-block mixing, improves distributive mixing and reduces domain size. Blown-film converters should also evaluate chill-air volume and internal bubble pressure, because the lower melt strength of C4 LLDPE changes the response to external air ring settings.
Under normal warehouse conditions, M13024T pellets do not require desiccant drying because LLDPE is not hygroscopic. Condensation on cold pellet surfaces remains the primary moisture-related failure mode. Pellets stored in unheated silos or exposed to relative humidity above 60 % should be brought above the ambient dew point before hopper loading; otherwise surface moisture can generate film defects and reduce melt clarity. The maximum recommended storage temperature is below 50 °C to avoid pellet agglomeration and additive migration. The stabilizer package is intended for melt processing and short-term thermal protection, not for long-term outdoor weathering; prolonged UV exposure during outdoor storage can raise gel levels and shift colour. These boundaries apply to the unmodified grade and do not remove the need to evaluate masterbatch concentrates, recycled material, or printed regrind added at the conversion step.
For food-contact applications, the base olefinic resin is typically assessed under FDA 21 CFR 177.1520 for U.S. uses and under EU Commission Regulation (EU) No 10/2011 for European uses. Overall migration testing is performed according to the EN 1186 series, and specific migration limits are evaluated according to the applicable simulant and migration tests in EN 13130. The converter must confirm the finished article, including all masterbatches, slip/antiblock concentrates, and recycled material, meets the relevant overall migration limit. For industrial films, compliance statements may include REACH and RoHS Directive 2011/65/EU, but these are product-specific and should be requested from the SABIC grade documentation. The presence of a compliant base resin does not automatically confer compliance on a multilayer structure that includes adhesives, tie resins, or printing inks.

In thin-gauge cast-film applications, M13024T is processed through a flat die with die gap typically 0.5–0.8 mm onto a chill roll maintained at 15–20 °C. Gauge uniformity is controlled by air knife positioning and die bolt adjustment; automatic die-bolt systems with infrared thickness scanning maintain film thickness variation below ±3 % on commercial lines running at 300–500 m/min. The low melt flow resistance of the C4 grade supports stable melt curtains at high line speed, but die-lip build-up remains the practical throughput constraint. Film produced from M13024T is used in overwrap, lamination, and protective packaging where the density and melt index provide a balance of clarity, sealability, and tear resistance. The substitution of this grade into an existing LDPE or C6 LLDPE line should be preceded by a trial that records die pressure, melt temperature, chill-roll release, and seal strength, because equipment-specific thermal history changes the additive consumption and the final film property envelope.
