A SABIC LDPE Price List: What a Quotation Actually Includes is best read as a composite commercial document rather than a single bulk resin indicator. The price list item brings together a base polymer value referenced to the current ethylene monomer contract settlement or a defined regional LDPE index, a conversion margin covering high-pressure autoclave or tubular reactor operating costs, additive package costs for slip, antiblock, antioxidant and release systems, packaging format charges, palletisation and strapping, inland freight loading onto an ISO container or bulk hopper vehicle, applicable port charges, and the Incoterms 2020 position at which risk transfers. Quotations also carry a limited validity window, typically 7 days for non-formula business, because ethylene feedstock and logistics surcharges can move within a working week. The technical annex to the quotation normally lists the grade designation, nominal melt mass-flow rate at 190 °C/2.16 kg, density, and the regulatory statements available for that grade.

For converters, misreading the list as an ex-works bulk price creates a recurring discrepancy between initial budget and invoiced amount. A quotation that includes 25 kg bags on heat-treated pallets differs from a bulk tanker quote. If the buyer requests an FDA 21 CFR 177.1520 statement, REACH registration confirmation and a batch-specific certificate of analysis, those documents are generated by the supplier but are not part of the base price unless stated. The quotation’s core value therefore sits at the intersection of polymer physics and logistics; a technically valid LDPE grade at an apparently low ex-works unit value may carry higher total cost once packaging, palletisation and delivery are appended.

Which Melt-Flow and Density Data Points Appear in a SABIC LDPE Quote?

The quotation’s technical section does not merely state “LDPE film grade.” It identifies the product by melt mass-flow rate under ASTM D1238-23 or ISO 1133-1:2022, measured at 190 °C under 2.16 kg, using a tungsten carbide die with a bore diameter of 2.095 mm and length of 8.000 mm. Density is reported by ISO 1183-1:2019 method A or ASTM D792-20. Film grades for SABIC LDPE typically fall between 0.3 g/10 min and 4.0 g/10 min, with densities from 0.918 g/cm³ to 0.924 g/cm³. Extrusion-coating grades are often quoted at higher MFR values, commonly 4.0 g/10 min to 8.0 g/10 min, because the melt must draw at high line speeds without excessive neck-in. Injection-moulding LDPE grades may appear from 20 g/10 min to 70 g/10 min. The quotation may also state whether the MFR value is a nominal datasheet value or a certificate of analysis result from a specific production lot.

For high-shear conversion processes such as extrusion coating, a single low-shear MFR value cannot describe shear-thinning behaviour; a capillary rheometry curve covering apparent shear rates from 10 s⁻¹ to 10⁴ s⁻¹ at 190 °C is sometimes attached. Molecular weight distribution is usually not shown in a standard price list quotation. If the conversion process demands narrow molecular weight distribution for draw stability, the quotation may reference an available technical datasheet rather than a contractual value. The quoted density and MFR should be read with their test uncertainty; repeatability limits under ISO 1133-1:2022 are method-dependent because LDPE is a branched polymer and thermal history during pelletisation affects the measurement. For this reason, a technically rigorous quotation will reference the exact standard revision, the die dimensions and the load.

Price movement in SABIC LDPE listings is strongly coupled to ethylene monomer contract settlements rather than to daily polymer spot screens. The base resin line in a quotation reflects the relevant ethylene contract price plus a polymerisation conversion margin covering high-pressure reactor energy, initiator consumption, and quality control. The actual cost build-up includes physical delivery: 25 kg multi-wall paper sacks with internal PE liners, or 1,250 kg flexible intermediate bulk containers, each with associated filling, stitching, palletising, stretch wrapping and labelling. Quotations that target food packaging may include slip additive loadings between 500 ppm and 1,500 ppm of erucamide or oleamide and antiblock loadings from 1,000 ppm to 10,000 ppm of synthetic silica; those loadings alter the final polymer cost. Quotations may also include antioxidant packages, typically hindered phenolic or phosphite systems at combined loadings below 3,000 ppm. The SABIC regional price list does not publicly disclose the exact conversion margin; published data for the specific formula is limited. Buyers should treat any listed increase or decrease as a directional indication, not a binding cost breakdown. If the quotation is supplied as a formula price, the buyer receives an ethylene index plus a fixed add-on, and the add-on includes stable costs while the index leg moves with the selected monomer publication.

When Packaging Standard Moves from 25 kg Bags to 1,250 kg Fibc, Which Quotation Fields Shift?

Packaging changes alter the delivered kilogramnage per truck or container, the unloading method, and the contamination risk. A 25 kg bag line is commonly palletised at 55 bags per pallet, giving 1,375 kg net per pallet, though pallet patterns vary by region. An 1,250 kg FIBC line may be loaded as single bags, reducing unpacking labour but requiring a fork-lift with appropriate lift capacity and a dust-controlled discharge station for vacuum conveying. The quotation therefore shifts in three non-polymer fields: packaging rental or purchase, pallet penalty for non-returnable pallets, and freight density. If the converter specifies ISPM 15 heat-treated timber, the quotation adds the compliance certificate and a higher pallet cost. These items appear as separate line items on a properly constructed SABIC LDPE quotation. They are not part of the base polymer price. The technical grade remains unchanged, but the quoted lot size, minimum order quantity, and delivery lead time may differ between bag and FIBC because FIBC filling lines are slower and require a dedicated packing bay. Converters receiving material in FIBC sometimes observe higher residual bridging if the FIBC has poor liner integrity, so the quote should specify whether the FIBC is fitted with a continuous inner PE liner and bottom discharge spout.

Quotation Attachments and the Technical Documents Embedded Within Them

A SABIC LDPE quotation is often issued with a set of documents. The table summarises the documents that should be requested and the standard or regulation they reference.

When a quotation references these documents without attaching them, the buyer should request the relevant product stewardship declaration before commercial release. A batch-specific certificate of analysis may list only the melt flow rate and density; it does not automatically include migration testing results. The quotation line item “food-contact grade” is therefore without technical force unless the cited regulatory text and the exact use limitations are specified, particularly in fatty foods where specific migration testing is required under EU 10/2011.

Comparing Film, Coating, and Injection-Moulding LDPE Quotations

Quotations for different LDPE applications are not differentiated by price alone; they are differentiated by melt-flow range, density, additive loadings, and acceptance test methods. A film-grade quotation may specify MFR 0.3 g/10 min to 4.0 g/10 min, density 0.918 g/cm³ to 0.924 g/cm³, and optical tests. A coating-grade quote for liquid packaging board may specify MFR 4.0 g/10 min to 8.0 g/10 min and neck-in data from a pilot coating line. An injection-moulding LDPE quote may specify higher MFR and mould shrinkage according to ISO 294-4:2018. The table provides a general comparison for the molten and solid-state values a buyer may see in a SABIC LDPE price list technical annex.

These ranges are not contractual unless the quotation expressly binds them to a batch certificate of analysis. They are typical published ranges for LDPE across major producers, and published SABIC grade-specific data for every application is limited without a grade datasheet. The quotation should identify whether the reference is a nominal datasheet pattern or a certificate of analysis-enforced range.

Regional SABIC LDPE price lists vary by production site and contract framework. A quotation from a European plant may be expressed in EUR per metric tonne FCA Antwerp under Incoterms 2020, while a Middle Eastern plant quote may appear as CIF main port or CFR and include marine freight. The freight component in a CFR quote covers ocean carriage to the named destination port, but insurance remains with the buyer unless the term is CIF. The price list does not include import duty, VAT, port handling, customs clearance or domestic trucking unless explicitly stated. Those post-arrival charges can add a material amount to the landed cost. For a converter comparing quotations, the invoice value should be normalised by delivered cost per kilogram at the silo or warehouse. A SABIC LDPE price list that quotes FCA rather than CIF shifts risk at the seller’s facility, and the buyer pays freight. This is not a hidden deficiency; it is a different legal delivery form. If the quotation lacks an Incoterm reference, the offered unit price cannot be interpreted unambiguously under sales contract rules.

For film converters, quotation comparison often focuses on extruder output and gauge variation. However, a SABIC LDPE price list quotation rarely guarantees optical or mechanical properties. Film-grade LDPE datasheets may list haze measured by ASTM D1003-21 and dart impact by ISO 7765-1:2018, but those are typical values obtained on laboratory cast or blown film lines. On production lines, the same resin can show different haze depending on die gap, melt temperature profile, frost line height and blow-up ratio. A quotation that includes a specific optical threshold must state whether that threshold is contractual or indicative. If the converter requires a maximum haze value below 7% or a dart impact above 100 g, those values should be written as acceptance criteria, not as references to the datasheet. Otherwise the quotation provides no technical recourse if line results differ. Similarly, tensile properties are measured by ISO 527-3:2018 or ASTM D882-18 on conditioned film; the quotation should specify sample orientation, test speed and conditioning at 23 °C and 50% relative humidity.

LDPE is not compatible with continuous exposure to strong oxidising agents or to solvents such as aromatic hydrocarbons under stress. Technical quotations sometimes omit service boundary conditions. A converter designing a packaging item for direct contact with an organic solvent should not rely on LDPE without conducting environmental stress cracking resistance testing under ASTM D1693-21 or ISO 4599. LDPE film retains dimensional stability only below about 80 °C under zero mechanical load; packages destined for hot fill require either a higher-density polyolefin or explicit application testing. In blown film, excessive melt temperature above 220 °C can generate oxidative degradation even with antioxidant packages, producing gel contamination and reduced tear strength. Moisture absorption is low, but surface moisture on pellets can be entrained at high throughput in humid environments; pre-drying is not mandatory below 60% relative humidity, but cold pellet handling under humid air may require surface drying. These boundaries are part of the quotation conversation only when the buyer specifies the end-use environment, because the base SABIC LDPE price list entry does not assume a particular converting condition.

Handling and storage boundaries also appear only when the buyer requests them. LDPE pellets should be stored away from UV light and heat sources above 40 °C. Silo storage requires dry, clean air to prevent pellet skin build-up on walls. For film production, dust contamination from poorly cleaned silos can generate melt gels and optical defects; a quotation cannot guarantee film clarity if the converter’s silo is cross-contaminated. Clean-in-place and purge procedures are downstream variables. This is a process boundary rather than a material defect. Quotations may include a shelf-life recommendation, often 24 months from production date when stored under 25 °C and 50% relative humidity. Additive migration and antioxidant depletion occur slowly, but storage beyond the stated shelf life does not automatically destroy the material; mechanical and optical properties should be re-verified before use. A SABIC LDPE price list item therefore carries technical boundaries that are not always printed on the first page but are available as product stewardship and technical datasheet documents.
