HDPE vs LLDPE vs LDPE — At a Glance
| Property | HDPE | LLDPE | LDPE |
|---|---|---|---|
| Branching / chain structure | Linear, minimal branching | Linear with controlled short-chain branching (α-olefin comonomer) | Highly branched (long- and short-chain branches) from high-pressure polymerisation |
| Density range | ≥0.940 g/cm³ (Syntex grades 0.949–0.954) | 0.915–0.925 g/cm³ (Syntex grades 0.918–0.922) | ~0.910–0.925 g/cm³ (G03-5 at 0.920) |
| Tensile strength / stiffness | Highest in the PE family — rigid, high crystallinity | Moderate — superior puncture and tear vs LDPE at similar density | Lowest tensile, softest, most flexible |
| Optical clarity | Opaque to translucent | Translucent — improved clarity with metallocene grades | Best clarity in the family at the same gauge |
| MFI offered by Syntex (ASTM D1238) | 0.04–0.35 g/10 min (blow & film grades) | 0.85–2.0 g/10 min (film & blow grades) | 0.30 g/10 min (film grade G03-5) |
| Typical processing | Blow moulding (5502BM); blown & cast film (E924, H5604F, HF49007) | Blown & cast film extrusion (2645G, DOWLEX2645, FP120-A, L1221FA, LF9120CC); blow moulding (HJ016364) | Blown & cast film extrusion (G03-5), typically blended with LLDPE |
| Resin Identification Code (ASTM D7611) | 2 | 4 | 4 |
| Brazilian NCM | 3901.20.29 | 3901.10.30 (film) / 3901.10.20 (blow) | 3901.10.30 |
How to choose between HDPE, LLDPE, and LDPE — across the 11 PE grades supplied by Syntex America
A four-step decision framework for selecting the right polyethylene grade among the four HDPE, six LLDPE, and one LDPE SKUs in Syntex America's catalogue.
- Step 1
Identify the processing method — film vs blow moulding
Start with how the part will be made. For extrusion blow moulding of bottles, jerricans, and rigid containers, select 5502BM (HDPE, Petkim) or HJ016364 (LLDPE, INEOS). For blown- or cast-film extrusion of bags, sacks, stretch wrap, lamination, or shrink film, choose from the nine film grades: E924, H5604F, HF49007 (HDPE) — or 2645G, DOWLEX2645, FP120-A, L1221FA, LF9120CC, G03-5 (LLDPE / LDPE).
- Step 2
Match density to stiffness and clarity requirements
Move along the density ladder according to the part's stiffness, clarity, and stretch profile. Specify HDPE (≥0.940 g/cm³) for rigid blow-moulded containers, heavy-duty films, and high-stiffness bags. Specify LLDPE (0.915–0.925 g/cm³ industry range; 0.918–0.922 g/cm³ across the Syntex grades) when you need balanced stretch, puncture, and seal strength — for stretch wrap, FFS bags, lamination, and most flexible packaging. Specify LDPE (G03-5 at 0.920 g/cm³) when clarity, seal performance, and bubble stability are critical — typically as a 10–30% blend with LLDPE.
- Step 3
Match MFI to part geometry and line output
Low MFI (HDPE film grades E924, H5604F, HF49007 at 0.04–0.06 g/10 min) supports thick-gauge film and stiff, heavy-duty bags with high melt strength. Mid-low MFI (5502BM at 0.35, G03-5 at 0.30) targets blow moulding and general LDPE film. Mid MFI (LLDPE film grades at 0.85–1.1 g/10 min) covers most blown- and cast-film production. High MFI (HJ016364 at 2.0 g/10 min) targets fast-cycle blow moulding of small and medium containers. Lower MFI = higher molecular weight = thicker walls and stronger melt; higher MFI = faster flow and thinner gauges.
- Step 4
Confirm food-contact compliance per grade
All eight manufacturers publish FDA 21 CFR 177.1520 compliance on their grade product cards. The six US-based producers (Dow, NOVA, INEOS, Chevron Phillips, Formosa, Westlake) also publish EU Regulation (EU) No 10/2011, RoHS 2, and REACH statements. For any food-contact, pharmaceutical, or consumer-packaging application, request the written compliance packet from Syntex America before specifying — the producer Statement of Compliance (SoC) is supplied per production lot at order.

Industry Standards & Food-Contact Compliance
Every PE grade in the catalogue is specified against ASTM D4976 (PE Plastics Molding and Extrusion Materials) and carries a Resin Identification Code under ASTM D7611 — Code 2 for HDPE, Code 4 for LLDPE and LDPE. Producer datasheets cite ASTM D1238 (MFI), ASTM D1505 (density), ASTM D638 (tensile), and ASTM D790 (flexural modulus) where reported.
Food-contact compliance is documented at the producer level: Dow, NOVA Chemicals, INEOS, Chevron Phillips Chemical, Formosa, and Westlake publish FDA 21 CFR 177.1520 and EU Regulation (EU) No 10/2011 on their grade cards; Petkim publishes FDA 21 CFR 177.1520 for 5502BM and G03-5; SCGC™ publishes FDA 21 CFR 177.1520 for H5604F and L1221FA. Syntex America delivers the written Statement of Compliance (SoC) for the production lot at order — covering FDA 21 CFR 177.1520, EU 10/2011, RoHS 2 (Directive 2011/65/EU), REACH (EC 1907/2006), and Packaging Directive 94/62/EC on request.
