HDPE vs LLDPE vs LDPE — At a Glance

How to choose between HDPE, mLLDPE, LLDPE and LDPE grades supplied by Syntex America

A decision framework for selecting the right polyethylene grade across the HDPE, metallocene and conventional LLDPE, and LDPE families in Syntex America's catalogue — by processing method, density, melt flow, and food-contact compliance.

1. 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).

2. 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.

3. 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.

4. 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.
