Film-grade linear low density polyethylene NOVAPOL LLDPE TF-0119-D with a nominal melt index of 1.0 g/10 min (ASTM D1238, 190 °C/2.16 kg) and density of 0.918 g/cm³ (ASTM D792) is processed on monolayer blown-film lines into heavy-duty shipping sacks. In this segment, the resin is run neat or as the major component in LLDPE/LDPE blends at 80–85 wt% TF-0119-D and 15–20 wt% LDPE having a density of 0.923 g/cm³; the LDPE fraction contributes bubble stability at blow-up ratios of 2.0:1 to 2.5:1 while the LLDPE fraction retains impact resistance after down-gauging to 50–70 µm. Extruders with 24:1 to 30:1 L/D and die gaps of 2.0–2.4 mm are employed, with melt temperature held between 190 °C and 220 °C. On converting equipment, a corona discharge level of 42–46 mN/m is applied before gusseted or back-seam sack formation. Compliance is anchored to ISO 21898:2004 for filled sack impact resistance, ASTM D1709 or ISO 7765-1 for dart impact, and ASTM D1922 or ISO 6383-2 for Elmendorf tear. Terminal products include polymer resin shipping sacks, mineral powder sacks, and self-standing FIBC inner liners. On lines without a dual-lip air ring, increasing TF-0119-D content above 85 wt% can induce bubble flutter at take-off speeds above 60 m/min, producing gauge bands at ±8–12% deviation.
Agricultural silage bag conversion with TF-0119-D uses a 3-layer blown-film coextrusion sequence in which the outer layers contain a white UV-stabilizer masterbatch at 6–10 wt%, the core layer is 80–90 wt% TF-0119-D, and the remaining percentage is a black carbon-black masterbatch or LDPE processing aid depending on required opacity. Total film thickness typically ranges from 70 µm to 90 µm. Die gap is set at 2.2 mm to 2.4 mm and frost line height is raised 15–20 cm above the conventional LLDPE position to preserve transverse direction tear. Compliance is assessed under EN 13206:2017 for thermoplastic agricultural films; specific mechanical requirements are verified through ISO 527-3 for tensile properties, ASTM D5748 for puncture resistance, and ISO 4892-2 for accelerated weathering after 1,000 h of UV-A exposure. Terminal products include silage storage bags, trench silo covers, and agricultural overwrap. A process limitation appears when the white masterbatch fraction exceeds 10 wt% because pigment agglomerates can destabilize the bubble at output rates above 180 kg/h on 90 mm extruders, leading to visible melt fracture in the frost line.
In frozen-food packaging structures, TF-0119-D is placed into the outer or core ply of 3-layer coextruded blown film at a typical loading of 30–40 wt% of total film thickness, with a low-density or metallocene LLDPE sealing layer to initiate heat seals below 110 °C. The film is produced at 50–70 µm thickness on water-quenched or ambient blown-film lines, using a die gap of 1.8–2.2 mm and a melt temperature of 195–215 °C to avoid surface oxidation. Low-temperature impact qualification is performed at -20 °C according to ASTM D1709 or ISO 7765-1. Food-contact compliance evaluations for olefin polymers follow 21 CFR 177.1520(c), with extraction testing according to 21 CFR 176.170(c) depending on the intended food type, and Regulation (EU) No 10/2011, Annex I and Annex II for specific migration limits. Terminal finished product types include frozen vegetable pouches, ice cube bags, and block-ice liners. Because this LLDPE grade is non-hygroscopic, pre-drying is not normally required, but surface condensation from cold storage must be removed before introduction into the hopper when relative humidity exceeds 80%.
Cast stretch film formulations run TF-0119-D at 60–80 wt% of the polymer fraction, with the balance drawn from a 2.5–3.5 g/10 min metallocene LLDPE to reduce extrusion back-pressure and improve machine-direction elongation. The cast process uses a 100–120 mm extruder with 30:1 L/D and a T-slot die having a 0.5–0.7 mm lip gap; melt temperature is maintained between 240 °C and 260 °C. Film thickness falls between 10 µm and 23 µm. Cling and stretch forces are measured under ASTM D5458 and ASTM D882. Regulatory documentation for European distribution is maintained under REACH Regulation (EC) No 1907/2006. Terminal products include hand pallet wrap, machine wrap, and bundling film. At line speeds above 300 m/min, the 1.0 g/10 min melt index of TF-0119-D contributes to elevated melt pressure; this requires a minimum 30 wt% mLLDPE in the blend to avoid melt-pressure spikes above 350 bar in the die. Published data for TF-0119-D in ultra-high-speed cast stretch processes exceeding 500 m/min is limited.
Industrial liners for construction debris, chemical drums, and building-material packaging are blown from TF-0119-D at 100–150 µm thickness. The formulation is typically 90–100 wt% TF-0119-D, with up to 10 wt% LDPE or regrind added only when bubble stability drops at high frost lines. Extrusion uses a 90–120 mm grooved-feed extruder with 24:1 to 30:1 L/D, die gap of 2.4 mm, and blow-up ratio of 1.8:1 to 2.2:1 to maintain tear balance. Puncture resistance is measured under ASTM D5748; tensile elongation under ASTM D882. Industrial packaging compliance references ISO 16495:2013 for transport packaging and, where recycled-content requirements apply, EN 15343:2007 for plastics recycling traceability. Terminal products include roll-off box liners, concrete curing covers, and chemical sack liners. A process boundary appears at film thicknesses above 150 µm, where cooling-limited crystallinity increases MD tear susceptibility unless air-ring refrigeration is upgraded.
For print-web and automatic packaging applications, TF-0119-D is used as the core layer in 3-layer blown films at 60–70 wt% of total thickness, with LDPE-rich skins at 20–25 wt% for seal initiation and surface gloss. The film is corona-treated inline to 38–42 mN/m for water-based flexographic ink adhesion. Extrusion conditions include die gap 2.0 mm, blow-up ratio 2.0:1, and melt temperature 190–210 °C. Compliance for packaging inks and substrates references REACH Regulation (EC) No 1907/2006, RoHS Directive 2011/65/EU where electronic packaging is involved, and ISO 14001 for site-level environmental management if required by the buyer. Terminal finished products include printed carry-out bags, textile packaging film, and magazine overwrap. On high-speed side-gusset bag machines, film thickness below 25 µm can produce seal-through-corner failures unless dwell time is increased by 15–20%.

NOVAPOL LLDPE TF-0119-D is a pelletized linear low-density polyethylene resin produced by copolymerization of ethylene with 1-butene. The grade is positioned by the resin supplier for cast film extrusion. The nominal melt flow rate is 1.0 g/10 min when measured at 190 °C under a 2.16 kg load according to ISO 1133-1:2022 or ASTM D1238. The nominal density is 0.919 g/cm³ according to ISO 1183-1:2019 or ASTM D1505. The differential scanning calorimetry peak melting temperature is approximately 124 °C at a ramp rate of 10 °C/min using ISO 11357-3:2018. These values are typical data points from publicly available product literature and are not specification limits; lot-specific certificates of analysis must be consulted for batch acceptance.
The intended conversion route is cast film, including monolayer and coextruded formats. The resin is used in stretch wrap, collation shrink, industrial liners, overwrap, and agricultural film. Its narrower molecular weight distribution and butene-derived ethyl branches produce a defined balance of melt delivery and solid-state toughness. In coextruded structures, the grade is typically placed in core layers rather than heat-seal skin layers when low-temperature sealing is required, because its seal initiation temperature is higher than that of 1-octene and metallocene LLDPE grades.
Storage in dry ambient conditions does not normally require pre-drying. Condensation on cold pellet surfaces can occur when resin is transferred from an unheated warehouse into a warm extrusion bay at relative humidity above 60%. In such cases, a desiccant or hot-air hopper dryer at 60 °C to 70 °C for 1 h reduces surface moisture and prevents film streaks. The resin should be purged with polyolefin-compatible materials and isolated from strong oxidizers and halogenated purge compounds that generate acidic by-products above 240 °C. No drying is necessary for typical cast-film operations, but surface moisture is a processing variable rather than a material specification.
On single-screw extruders with 30:1 to 33:1 L/D and a barrier feed section, the grade is normally processed with barrel set points between 200 °C and 240 °C, while adaptor and die zones are held from 240 °C to 270 °C. A flat-to-reverse temperature profile is used because the resin has a less shear-thinning melt than high-pressure LDPE. At die shear rates above 500 s⁻¹, melt fracture may appear if melt temperature is below 230 °C or if the die gap is set below 0.5 mm. On a 90 mm extruder, startup trials often begin at screw speeds of 60 rpm to 90 rpm, but published data for this specific configuration is limited; amp draw and head pressure must be checked against the screw manufacturer's curve.
The cast film die gap normally ranges from 0.6 mm to 1.0 mm for finished film thicknesses between 20 µm and 80 µm. Chill-roll temperature is maintained between 20 °C and 35 °C. Lower quench temperatures reduce haze in monolayer films, while higher roll temperatures improve cling-forming potential but increase blocking propensity if the D-suffix additive package is not correctly matched. Air-knife position, die-to-roll distance, and edge trim design are the main controls for neck-in and edge curl; the grade tends to exhibit less draw resonance than LDPE at equivalent melt index but requires uniform die-lip adjustment to avoid gauge bands.
When converted on air-cooled blown-film lines, the resin is usually blended with 10% to 30% high-pressure LDPE to stabilize the bubble. The butene architecture produces lower melt tension than LDPE at equivalent melt index, and a high-stalk bubble can exhibit surging and gauge variation when the frost line height exceeds 3 die diameters. Published film data from blown-film conversion of this exact grade is limited; process trials should not use high-stalk configurations without evaluating gauge profile under ISO 4593 and tensile properties under ASTM D882.
NOVAPOL LLDPE TF-0119-D differs from higher-performance LLDPE film grades because the comonomer is 1-butene, which inserts ethyl branches along the polyethylene backbone. At equal density, a butene copolymer requires a higher comonomer molar fraction than a 1-octene copolymer and forms shorter branch lengths. Branch length affects tie-chain formation and entanglement in the quenched film; the two-carbon branches in butene copolymers are generally less effective than the six-carbon branches in octene copolymers at resisting dart impact and tear propagation. This structural boundary defines the grade's position in cast film portfolios and should not be interpreted as a uniform performance equivalence to octene LLDPE.
Against high-pressure LDPE of similar melt index and density, the linear grade delivers higher tensile yield stress and improved puncture resistance but lower melt extensibility and less shear thinning. The metering zone therefore generates less viscous heating for a given screw speed, and barrel set temperatures may need to be 10 °C to 20 °C higher than for LDPE to reach the same melt temperature. Substitution based on density alone is not valid because melt index, comonomer type, and molecular weight distribution interact with screw design. Comparative melt viscosity at 100 s⁻¹ and 190 °C for a 1.0 g/10 min LLDPE is typically lower than that of a 0.3 g/10 min LDPE; the relevant comparison must include both melt index and shear rate.
| Attribute | NOVAPOL LLDPE TF-0119-D | 1-Octene LLDPE cast film grade | Metallocene LLDPE cast film grade |
|---|---|---|---|
| Comonomer | 1-butene | 1-octene | 1-hexene or 1-octene |
| Short-chain branch length | ethyl | hexyl | butyl or hexyl |
| Dart impact at 25 µm using ASTM D1709 | baseline | higher | higher |
| Elmendorf tear using ASTM D1922 | baseline | higher | higher |
| Heat-seal initiation using ASTM F1921 | higher | lower | lower |
| Melt strength at comparable melt index | lower versus LDPE | moderate | narrow MWD may reduce melt strength |
The practical consequence of the butene architecture appears in high-speed cast film and stretch-wrap operations. When pre-stretch ratios exceed 150%, the film can enter the strain-hardening region near the stretch rollers, and the butene grade may develop stress whitening earlier than an octene resin of the same density and thickness. This limitation is evaluated using tensile elongation at break under ASTM D882 and puncture propagation tests under ASTM D5748. In coextruded stretch films, the resin is more commonly placed in the core layer than in the skin layer, where the outer surfaces can use a metallocene or polyisobutylene-containing tie layer to improve cling and puncture resistance.
The heat-seal response of TF-0119-D is governed by the melting peak near 124 °C. In form-fill-seal packaging, seal dwell times of 0.5 s to 0.8 s at seal-bar temperatures from 135 °C to 155 °C are typical starting conditions for monolayer cast film, but the seal strength and hot-tack profile under ASTM F1921 must be generated on the target film thickness. Because butene copolymers tend to have a higher seal initiation temperature than octene copolymers, the grade may not meet the low-temperature seal requirements of high-speed polyolefin packaging lines. Conversely, in ambient-temperature protective wrapping, this higher seal initiation point is less critical, and the film can be used where folding or adhesive tape replaces heat sealing.
In cast stretch-film applications, the tear and puncture performance under ASTM D5748 should be compared with the incumbent grade at identical film thickness and quench conditions. The D-suffix additive package influences coefficient of friction and blocking; published data for this specific configuration is limited if the exact additive levels are not disclosed. For high-cling machine-wrap structures, the film often requires a secondary cling additive, and the processing window must be re-validated because additive migration kinetics vary with storage temperature and film crystallinity.
| Property | Nominal Value | Test Method |
|---|---|---|
| Melt flow rate at 190 °C, 2.16 kg | 1.0 g/10 min | ISO 1133-1:2022 / ASTM D1238 |
| Density | 0.919 g/cm³ | ISO 1183-1:2019 / ASTM D1505 |
| Peak melting temperature | 124 °C | ISO 11357-3:2018 / ASTM D3418 |
The base polyethylene may be considered under 21 CFR 177.1520 for olefin polymers in food-contact applications, but the final film must be evaluated for overall migration and specific migration limits under EU 10/2011 or applicable national regulations. The D-suffix additive package, if it contains slip and antiblock agents, must be covered by the supplier's regulatory documentation before a food-contact declaration is issued. RoHS and REACH conformity for the base resin should be verified through the supplier's material safety data sheet and regulatory certificate; the standard grade is not formulated with cadmium, lead, or phthalate additives.
Recycled edge trim and roll scrap can be re-pelletized and added back in most cast film operations. The maximum rework addition should be established by film gauge and optical testing under ASTM D1003; published data for this specific configuration is limited. Processors that exceed scrap addition beyond 10% to 15% often observe gel counts and film clarity loss unless the scrap is dried and melt-filtered through a 100 µm screen pack. The resin should not be compounded with incompatible acid-functional polymers or amine-bearing additives that can produce color bodies and plate-out on the chill roll.
For agricultural film and outdoor exposure longer than 6 months, a UV stabilizer masterbatch is required. The base resin does not claim UV resistance beyond standard polyethylene weathering stability, and outdoor performance must be validated under ASTM G154 or ISO 4892-2. The addition of hindered amine light stabilizers at supplier-recommended levels may alter film quench and blocking behavior, so processing trials should include additive concentration gradients rather than point estimates.
Comparative substitution trials should use the same film gauge, blow-up ratio or cast die gap, chill roll temperature, and test conditioning state under ISO 291 or ASTM D618. Property differences are not meaningful unless films are tested after conditioning for at least 40 h at 23 °C and 50% relative humidity.
For stretch film requiring cling and sustained unwind, the film's coefficient of friction is typically measured under ASTM D1894. The as-pelletized resin may not contain sufficient cling agent for high-tack machine wrap; processors often add 2% to 5% of a cling masterbatch or use a skin-layer formulation. Slip additives that lower coefficient of friction can compete with cling additives and bloom to the film surface over time. In a coextruded A/B/A structure, the core layer can be run with TF-0119-D while the skins are supplied by a softer or higher-cling LLDPE or mLLDPE; this configuration isolates the butene grade's lower tear baseline from the outer surfaces.
Melt flow index is only one point on the viscosity curve. A full capillary rheometry comparison under ASTM D3835 or ISO 11443:2021 is required when the grade is substituted into a high-speed cast film line with low die residence time. The shear viscosity at 100 s⁻¹, 500 s⁻¹, and 1000 s⁻¹ should be compared with the incumbent grade; if the melt flow index matches but the high-shear viscosity differs, die pressure and melt temperature will shift. Published data for this specific grade is limited, and pilot-line measurements should not be extrapolated to commercial-scale throughput without correction for adiabatic shear heating.
In cast film, the rapid quench produces lower crystallinity than blown film and can increase transverse-direction tear strength relative to machine-direction tear. The orientation balance is controlled by die-to-roll distance, air-knife flow, and line speed. Because the butene backbone has lower melt strength, excessive draw can create machine-direction orientation and a corresponding loss in transverse-direction tear under ASTM D1922. Film processors should compare tear anisotropy rather than single-point tear values; a machine-direction tear value alone does not capture the grade's applicability for hand wrap or pallet wrap.
The D-suffix designation typically indicates the presence of a standard additive package for film surface properties. If the end use requires low haze or high gloss, the base grade may need an external clarifying or antiblock masterbatch. Haze is measured under ASTM D1003, and gloss under ASTM D2457; without those measurements, visual inspection is not a valid specification tool. Published data for this specific configuration is limited with respect to optical values.
On production-scale cast film lines equipped with gravimetric feeding and automatic die-bolt control, the grade typically produces stable melt pressure and web tension when the melt temperature is maintained between 240 °C and 270 °C. Deviations from this range can shift film crystallinity, surface roughness, and tear balance. Processors using direct edge trim recycle should monitor filter pressure and die pressure for gel accumulation; a screen pack of 100 µm to 150 µm is common. Published data for this specific configuration is limited, so commissioning trials are required to establish lot-to-lot variability and product-specific mechanical performance.
