Request a QuoteThe short answer
DOWLEX 2045G is Dow's linear low density polyethylene (octene copolymer), sold for industrial and consumer blown film. Published melt flow is 1.0 g/10 min, measured at 190°C / 374°F, 2.16 kg, ASTM D1238, and density is 0.920 g/cm³ (ASTM D792). Grades from other producers to ask about include SCLAIR FP120-A and Petrothene GA601030. They are not identical, so compare the data sheets and run a trial before switching.
DOWLEX 2045G specs from the data sheet
Typical values from Dow's published data sheet. Typical values are not specifications; the lot COA shows what you actually receive. Values only compare at the same test method and condition.

| Dart drop impact | 220 g | ASTM D1709A |
| Elmendorf tear, MD / TD | 370 g / 630 g | ASTM D1922 |

| Vicat softening point | 106°C / 223°F | Dow page (method not stated) |
| Melting point, DSC | 119°C / 246°F | Dow method |
| Additives | No slip, no antiblock (Dow product page) | |
| Food contact | Distributor listings (Resinex, UL Prospector) state it complies with FDA 21 CFR 177.1520 (c) 3.2a. Dow's public page does not state it; ask Dow for its current letter before food use. |

Grades to ask about instead of DOWLEX 2045G
These grades from other producers have similar published specs. None is a drop-in replacement: additive packages, flow at molding shear rates, color and approvals differ. If your part, drawing or customer approval names DOWLEX 2045G, any change needs your approval and usually a trial.
| Grade | Producer | Melt flow | Density | Key property | How it compares |
|---|---|---|---|---|---|
| SCLAIR FP120-A | NOVA Chemicals | 1.0 g/10 min (190°C / 374°F, 2.16 kg, ASTM D1238) | 0.920 g/cm³ (ASTM D792) | Dart drop 270 g at 1.0 mil (FP120 series sheet; typical values shown for FP120-D02) | Octene LLDPE film resin; FP120-A carries processing antioxidant only. MI, density and dart on NOVA's series sheet are typical values for FP120-D02 (the slip/antiblock version), so confirm FP120-A values with NOVA. |
| Petrothene GA601030 | LyondellBasell | 1.0 g/10 min (190°C / 374°F, 2.16 kg, ASTM D1238) | 0.918 g/cm³ (ASTM D1505) | Dart drop 190 g at 1.0 mil; Elmendorf MD 325 g / TD 650 g | LLDPE film resin, no slip or antiblock; comonomer not stated on data sheet |

Typical uses for DOWLEX 2045G
From Dow's data sheet and published listings:
- Industrial and consumer packaging
- Heavy duty shipping sacks
- Shrink film
- Agricultural films
- Stretch film
- Industrial films
- Food and specialty packaging
What to check before you switch
- Look-alike names exist, for example DOWLEX 2045.01G, which Resinex lists with slip and antiblock (density 0.922 g/cm³). Put the exact name on the PO.
- Dow's page does not state the film gauge for its film properties; compare at equal gauge and blow-up ratio.
- Octene (2045G, FP120-A) versus butene or hexene LLDPE changes tear and dart; GA601030's comonomer is not stated on its data sheet.
- Density 0.918 (GA601030) versus 0.920 shifts stiffness and seal initiation slightly.
- The octene comonomer is stated in distributor listings (Resinex lists LLDPE C8 octene); Dow's public page does not state it.
- Compare melt flow, density and impact only at the same test condition and method (ASTM vs. ISO results differ).
- Ask for the producer's food-contact or regulatory letter for the exact grade if the part needs one.
- Run a trial lot and check shrinkage, cycle time and appearance before you switch production.
Buying DOWLEX 2045G or an equivalent
Send us the grade name, your annual volume and ship-to location. A polymer chemist checks the data sheet and we quote DOWLEX 2045G where we can source it, or a qualified equivalent, saying clearly which one you would get. Orders start at one gaylord. For background on this resin family see LLDPE Film Resin; for several grades at once, use the resin RFQ template.
Trade names belong to their owners. ResinBridge is not affiliated with these producers; grade names are used only to identify the material. Data reflects published sheets as of October 2026.
