Extrusion of HANWHA LLDPE 4030 for heavy-duty industrial liners is performed on single-screw blown-film equipment with screw diameters in the 65–90 mm range and L/D ratios of 25:1 to 30:1. The resin is a butene-based linear low-density polyethylene with nominal density 0.920 g/cm³ and melt flow rate 0.40 g/10 min when measured under ISO 1133-1:2022 at 190 °C/2.16 kg. In a three-component dry blend containing 80 wt% LLDPE 4030, 12 wt% autoclave LDPE, and 8 wt% HDPE, the compound is processed at melt temperatures of 190–220 °C, with die gaps of 1.8–2.4 mm, blow-up ratios of 2.5:1 to 3.0:1, and frost line heights of 700–900 mm. The LDPE fraction adds melt extensibility and stabilizes the bubble against edge flutter on high-speed lines with dual-lip air rings; the HDPE fraction raises tensile modulus and puncture resistance but its addition must remain below 10 wt% because higher loadings create a property cliff in dart impact. Published industrial data for this specific resin formulation is limited, but converter trials on 100 μm liners generally target dart impact values above 450 g per ASTM D1709 Method A and Elmendorf tear values above 350 g per ASTM D1922. Process operators monitor melt pressure at the breaker plate; excursions above 420 bar on 90 mm extruders indicate poor solid conveying or too low a profile in the feed zone, while melt temperature above 225 °C initiates surface oxidation and gel formation. Because melt flow rate can vary by ±0.05 g/10 min across production lots, initial melt pressure on a 90 mm extruder may move by 10–20 bar; screw speed is trimmed to maintain bubble stability. Use of an inert gas purge at the die lip and internal bubble cooling extends the operating window by 10–15 °C on high-output lines.
In agricultural mulch film at thicknesses of 15–25 μm, the processing constraint is not melt temperature alone but the vertical distance between the die exit and the point where the film solidifies. With HANWHA LLDPE 4030, film lines carrying carbon black masterbatch at 6–8 wt% and a hindered amine light stabilizer concentrate at 0.5–1.0 wt% maintain stable bubbles at blow-up ratios of 2.8:1 to 3.2:1 when the frost line is held between 700 mm and 900 mm. Higher frost lines above 1000 mm produce excessive transverse direction orientation relaxation and reduce edge fold recovery, while lower frost lines below 600 mm increase haze and create film blocking on the winding roll. The butene comonomer distribution in 4030 gives a wider melt strength plateau than a comparable C6 LLDPE, but the base resin contains no ultraviolet stabilizer; outdoor service life depends entirely on the added masterbatch. In regions with high ultraviolet exposure, a three-layer A/B/A structure with 8 wt% carbon black in the outer layers and 3–4 wt% in the core reduces overall masterbatch consumption while maintaining opacity. Tensile properties are assessed under ISO 527-3, tear resistance under ASTM D1922, and dart drop impact under ISO 7765-1. Processors using internal bubble stabilization report that frost line control must be coupled to haul-off speed; increasing line speed from 45 m/min to 60 m/min without raising air volume shifts the frost line upward by 200 mm and destabilizes the bubble. A corrective sequence is to raise the external air ring pressure by 0.05–0.10 bar and reduce melt temperature by 5–10 °C, but not below 185 °C, where melt fracture may appear at die gaps below 1.8 mm.
For coextruded films requiring low seal initiation temperature and high hot-tack strength, HANWHA LLDPE 4030 is used as the toughness component in a sealant layer at loadings of 70–80 wt% with 20–30 wt% metallocene LLDPE having density 0.905–0.912 g/cm³. The metallocene fraction lowers seal initiation to 90–105 °C; the 4030 fraction maintains dart impact and prevents the sealant layer from thinning during draw-down in the primary film direction. Pellets are gravimetrically dosed and fed to a three-layer blown-film line with die gaps of 1.6–2.0 mm, melt temperatures of 195–215 °C, and blow-up ratios of 2.2:1 to 2.6:1. Heat seal strength is evaluated per ASTM F88 after 0.5 s dwell at 0.27 MPa sealing pressure; hot tack is measured per ASTM F1921. A stable operating window for 4030-based sealants is between 115 °C and 130 °C. Above 140 °C, seal failure shifts to tearing along the seal edge, and the sealant layer can shrink enough to distort the laminate. Compliance with indirect food contact requires that the formulated sealant layer meet FDA 21 CFR 177.1520 for olefin polymers and EU Regulation 10/2011 overall migration limits of 10 mg/dm²; this applies only when the added slip and antiblock concentrates are themselves compliant. In high-speed vertical form-fill-seal operations, a 1000 ppm erucamide slip loading reduces coefficient of friction to 0.15–0.20 per ASTM D1894, but loadings above 1500 ppm plate out on sealing jaws and create intermittent seal failures. The same limitation appears when behenamide is substituted; the amide bloom rate is temperature-dependent and accelerates in warehouses above 30 °C.
Extrusion coating of corona-treated polypropylene woven fabric with HANWHA LLDPE 4030 is executed on single-screw extruders of 90–120 mm diameter and 30:1 L/D, fitted with flat dies and chill-roll cooling. Melt temperatures for coating are 280–320 °C, higher than in blown film to promote oxidation-polarization adhesion to the substrate. The fabric surface must reach a minimum wetting tension of 42–48 dyn/cm immediately before the coating nip; lower levels result in delamination under ASTM F88 seal tests. Because the low melt index of 4030 increases neck-in, 10–20 wt% LDPE with a melt index of 4–8 g/10 min is blended inline to stabilize the web edges. Coating weights between 15 g/m² and 40 g/m² are used depending on the bag size; below 15 g/m², pinholes and weave pattern bleed-through become visible, while above 40 g/m² the coating adds weight without proportional seal strength gain. On high-speed lines running 120–160 m/min, the nip pressure is held at 0.25–0.35 MPa and the chill roll temperature at 15–25 °C to prevent blocking. The coated woven sacks are tested for seal strength under ASTM F88, dart impact under ASTM D1709, and flexural cracking resistance through 10,000-cycle flex tests on filled bags. A significant processing conflict arises when the corona treater operates above 50 dyn/cm; the oxidized fabric can block heat-seal jaws and leave residue on the polytetrafluoroethylene release tape. Published data for this specific 4030 coating configuration is limited, but production-scale experience indicates that melt pressure should remain below 250 bar to avoid degradation-related gel formation in the die lip.
Form-fill-seal tubular film for 25–50 kg shipping sacks is produced from a blend of 60–70 wt% HANWHA LLDPE 4030, 20–30 wt% autoclave LDPE, and 5–10 wt% HDPE. The replacement of a conventional LDPE-rich formulation with 4030 raises low-strain tensile modulus and impact strength, but requires adjustment of the haul-off and collapsing frame geometry. On oscillating haul-off lines, die gaps of 2.0–2.5 mm, blow-up ratios of 2.2:1 to 2.6:1, and frost line heights of 800–1200 mm are standard. The LDPE fraction prevents the higher shear viscosity of 4030 from generating melt fracture at die gaps below 2.0 mm; the HDPE fraction improves creep resistance and stackability of filled sacks. However, HDPE incorporation above 15 wt% produces a sharp decline in dart impact and film toughness as measured by ASTM D1709 and ISO 7765-1. Slip and antiblock packages are added at 500–1000 ppm erucamide and 2000–4000 ppm diatomaceous earth to maintain coefficient of friction below 0.20 under ASTM D1894. In filling trials on horizontal form-fill-seal machines running 35–50 bags/min, seal temperatures of 135–150 °C are required for reliable seal integrity because the LDPE fraction and the high molecular weight tail of 4030 shift seal initiation upward compared with metallocene LLDPE. Heat seal data per ASTM F88 indicate that seal strength above 30 N/15 mm is achieved only after a dwell time of 0.6–1.0 s. The main operational boundary is the coefficient of friction: below 0.08, bag misalignment on the forming collar increases; above 0.25, static charge builds on the film surface and causes blocking at the winder.
Coextruded geomembrane backing layers incorporate HANWHA LLDPE 4030 at 60–80 wt% with HDPE or MDPE for stress-crack-resistant sheet. Stress crack testing per ASTM D5397 is applied, though published data for this specific configuration is limited. Regrind above 20 wt% raises melt flow rate and lowers edge tear resistance.

Commercial documentation for HANWHA LLDPE 4030 identifies the material as a butene-1 linear low-density polyethylene produced by Hanwha TotalEnergies Petrochemical Co., Ltd. The two primary specification values governing material selection are melt flow rate and density. Melt flow rate, determined under ASTM D1238 at 190 °C with a 2.16 kg load, is nominally 4.0 g/10 min; density, determined under ASTM D1505 or ISO 1183-1, is nominally 0.930 g/cm³. The grade is supplied as pelletized reactor-grade polyolefin stabilized for film extrusion and is commonly delivered in 25 kg multi-wall bags or bulk silo trucks. In the producer’s LLDPE range, the 4.0 g/10 min flow value places the resin in the high-flow segment, while the 0.930 g/cm³ density provides higher modulus and lower permeability than conventional 0.918–0.922 g/cm³ blown film grades. The backbone is linear, and the short-chain branch population derives from butene-1 comonomer; long-chain branching is absent, which reduces melt elasticity relative to autoclave LDPE. These architectural features determine the grade’s main operational differences: higher line speed potential than lower-melt-flow LLDPE, but reduced bubble stability in blown film and reduced draw resonance thresholds in extrusion coating.
In cast film processing, HANWHA LLDPE 4030 is typically run on single-screw extruders with L/D 30:1 barrier screws and a die gap between 0.5 mm and 0.8 mm. Melt temperature at the feedblock is controlled between 220 °C and 240 °C; the chill roll temperature is set between 20 °C and 35 °C. Because the resin lacks long-chain branching, the air gap is kept at 10–15 cm to limit neck-in and gauge irregularity. Edge-bead formation is managed by deckle position and melt temperature rather than by increasing air gap; a wider air gap increases draw resonance risk without improving edge stability. Average residence time in the melt should be kept below 15 min above 240 °C to avoid antioxidant depletion and gel formation.
Under capillary rheometry, a 4.0 g/10 min butene-LLDPE shows shear-thinning onset at low shear rates and a power-law index between 0.55 and 0.65 at 100–1000 s⁻¹. On a 45 mm single-screw extruder with L/D 30:1, the resulting melt pressure at the breaker plate is typically 80–120 bar at screw speeds of 60–90 min⁻¹. These values are stated for comparative purposes and should be verified by lot-specific capillary rheometry; published data for this precise configuration is limited.
In blown film, blow-up ratio is normally maintained at 2.0–2.5, with frost line height at 3–6 die diameters. On a 65 mm grooved-feed extruder with L/D 30:1, the melt pressure for 4030 is approximately 15%–30% lower than for a 1.0 g/10 min butene-LLDPE at the same screw speed, based on comparative rheology; published data for this exact configuration is limited. The lower melt strength of 4030 reduces stability at high stalk heights, so operators often increase internal bubble cooling and reduce die gap to 1.2–1.6 mm. At thicknesses below 20 µm, gauge uniformity becomes sensitive to melt temperature uniformity and die lip cleanliness; screen packs of 60/80/100 mesh are used to retain carbonized gels.
Chill roll and film tower parameters are not directly transferable from LDPE. A branched LDPE of equivalent melt index tolerates a higher blow-up ratio because long-chain branching provides extensional strain hardening. LLDPE 4030 does not exhibit the same strain hardening; therefore, bubble oscillation and stalk resonance appear at lower frost line heights unless internal bubble cooling is increased. Mechanical properties such as machine-direction and transverse-direction tear balance are controlled by blow-up ratio and frost line; unbalanced orientation produces weak transverse tear values under ASTM D1922.
Application use is concentrated in general-purpose packaging film, lamination layers, agricultural stretch film, and industrial liners. At 50 µm thickness, cast film of this density class typically shows dart impact values measured under ASTM D1709 and Elmendorf tear values under ASTM D1922 that are moderate relative to hexene-copolymer LLDPE grades. The density of 0.930 g/cm³ lowers moisture vapor transmission rate by roughly 5%–10% compared with a 0.920 g/cm³ LLDPE at equal gauge, as measured by ASTM E96; however, published data for this specific grade and gauge should be verified against supplier certificates. Tensile properties measured under ASTM D882 are orientation-dependent and should not be compared across films without reporting machine-direction and transverse-direction values.
For lamination layers, the grade is blended with autoclave LDPE at 20–30 wt% LLDPE to improve hot tack and stiffness while retaining acceptable neck-in control. The blend ratio is adjusted according to die width, line speed, and substrate type. Film gauge can be drawn from 20 µm to 120 µm on conventional lines, with tensile and impact values determined by gauge, frost line, and orientation balance.
Substitution of 4030 into an existing thin-gauge blown film line requires recalibration of die gap, frost line, and haul-off speed. A line configured for a 1.0 g/10 min resin often operates with a die gap of 1.6–2.0 mm and a blow-up ratio of 2.5–3.0. Switching to 4030 may require a die gap reduction to 1.2–1.5 mm and a blow-up ratio reduction to 2.0–2.2 to avoid bubble instability. Screw speed can be increased because melt viscosity is lower; however, shear heating may be lower at constant speed, and the barrel temperature profile must be rebalanced. The trade-off is a loss of dart impact and tear resistance as measured by ASTM D1709 and ASTM D1922, while output and gauge control improve.

A metallocene-catalysed hexene-LLDPE of equivalent melt flow and density typically exhibits higher dart impact, higher Elmendorf tear, and better hot tack than a Ziegler-Natta butene-copolymer such as 4030. The difference is caused by comonomer type and composition distribution; hexene branches are longer than butene branches and are more effective in tie-chain formation. In blown film, the hexene resin also permits a wider blow-up ratio and higher strain hardening. However, 4030 is often selected when the application does not require the additional toughness of hexene grades. Puncture resistance under ASTM D5748 and slow-rate penetration under ISO 6603-2 are commonly higher in LLDPE than in autoclave LDPE at equal gauge.
Compared with autoclave LDPE of equivalent melt index, LLDPE 4030 has higher tensile strength and puncture resistance at equal density, but lower melt elasticity. On extrusion coating lines, neat 4030 exhibits neck-in and draw resonance before LDPE, so it is usually blended with LDPE rather than processed alone at high line speed. The linear architecture also increases shear viscosity at high shear rates relative to LDPE of the same melt index, which can raise motor load in some coating dies.
For food-contact applications, HANWHA LLDPE 4030 is subject to FDA 21 CFR 177.1520 as an olefin polymer, provided that end-use extraction testing under 21 CFR 176.170 or 21 CFR 177.1520 conditions is completed for the final article. In the European Union, specific migration testing under Regulation (EU) No 10/2011 and its amendments determines compliance for the finished film or laminate. REACH registration under Regulation (EC) No 1907/2006 is the responsibility of the producer or importer; downstream users must verify exposure scenarios. For waste electrical and electronic equipment, the grade is assessed under Directive 2011/65/EU as amended by (EU) 2015/863; no intentionally added lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE is declared for the base resin. These statements are conditional and do not replace lot-specific certificates of compliance.
Storage of HANWHA LLDPE 4030 requires separation from sources of UV light, moisture, and high ambient temperature. In silos or bins, moisture uptake is not hydrolytically destructive, but surface moisture can disrupt film optical quality; if the resin has been exposed above 60% relative humidity for more than 24 h, dry it at 70 °C for 2 h in a desiccant-bed dryer before processing. Do not blend with incompatible additive concentrates that generate acidic or amine-functional byproducts at melt temperatures above 240 °C, as these can accelerate gel formation and die-lip deposit. Edge trim and off-spec film are mechanically recycled in many cast film operations at addition rates up to 20 wt% when flake bulk density and feeding are controlled.
