In high-stalk blown film extrusion for thin-gauge T-shirt grocery sacks, FTA-001 is processed through a grooved-feed extruder with a barrier screw of 24:1–30:1 L/D ratio, a die gap of 0.8–1.2 mm, a blow-up ratio of 3:1–4:1, and a melt discharge temperature of 190–210°C. The frost line is held at 5–9 die diameters above the dual-lip air ring to stabilize the high-density bubble and balance machine-direction and transverse-direction tear. If melt flow rate is verified on incoming resin, testing under ISO 1133-1:2022 at 190°C and 2.16 kg load should be used; deviations from the supplier-specified range alter frost line position and seal initiation on bag machines. Compliance for merchant film is based on FDA 21 CFR 177.1520(c) for olefin polymers and, where relevant, EU Regulation (EU) No 10/2011 with an overall migration limit of 10 mg/dm²; material specification follows ASTM D4976-23, and REACH SVHC screening applies in the European market. A representative formulation contains FTA-001 at 84 wt%, C6 linear low-density polyethylene at 10 wt%, white or color concentrate at 4 wt%, and a slip/antiblock masterbatch at 2 wt%; polymer processing aid is dosed at 300–800 ppm to suppress melt fracture on low die-gap surfaces. Downstream production involves bubble collapsing, inline gusseting, corona treatment when printing is required, and conversion on servo-driven bag machines operating at 150–300 cycles/min; roll tension is maintained below 0.5 N/cm to minimize blocking. Terminal finished products include T-shirt grocery sacks in 12–18 µm, produce roll bags, and thin merchandise bags. Property evaluation uses ASTM D1709-16a dart impact, ASTM D1922-23 Elmendorf tear, and ASTM D882-18 tensile at a 50 mm gauge length and 500 mm/min test speed.
When Does Post-Consumer Recyclate Blending Compromise Dart Impact in Can Liners?
The blending of post-consumer HDPE recyclate in institutional can liners creates a measurable processing boundary at 40 wt% substitution. On production-scale blown film lines with melt filtration of 150–250 µm and gear-pump pressure smoothing, formulations containing FTA-001 at 68 wt%, washed PCR HDPE at 28 wt%, carbon black masterbatch at 3 wt%, and antioxidant masterbatch at 1 wt% are run at melt temperatures of 190–230°C, die gaps of 1.0–1.5 mm, and blow-up ratios of 2.5:1–3.5:1. Compliance for refuse sacks is aligned with EN 13592 and the EU Packaging and Packaging Waste Directive 94/62/EC; food-contact status under FDA 21 CFR 177.1520(c) is normally not claimed for PCR-containing films unless the recyclate stream meets applicable regulatory approvals. The downstream production process uses a low-stalk bubble configuration, an external cooling ring, and a collapsing frame with gussets, followed by inline perforation and sealing. Terminal product types include 30–80 µm institutional can liners, janitorial bags, and wheeled-bin refuse sacks. The primary failure mode above 40 wt% PCR is loss of dart impact caused by gel particles and chain scission; downgauging below 25 µm is therefore limited unless the PCR stream is homogenized and filtered to 100 µm or finer. Published data for this specific FTA-001/PCR configuration is limited, so line trials are required to confirm exact dart impact retention at the target gauge.
Coextruded HDPE Core in Moisture-Barrier Cereal Liner Film
A three-layer blown film structure places FTA-001 in the core layer at 70 wt% of total film weight, with LDPE or C6 LLDPE skins at 30 wt% to supply heat-seal initiation and abuse resistance; slip/antiblock additives are incorporated into the skin layers at 1–2 wt% of the skin weight. The HDPE core provides a water vapor transmission rate of approximately 4–6 g/m²·day at 38°C and 90% relative humidity for a 25 µm layer when measured according to ASTM F1249-20. Compliance for dry food contact is governed by FDA 21 CFR 177.1520(c) and EU Regulation (EU) No 10/2011, including Annex I overall migration below 10 mg/dm² and additive-specific migration limits; formulations intended for food service must also be screened against REACH and local food-contact inventories. Production uses three extruders feeding a three-layer spiral mandrel die with a die gap of 1.0–1.5 mm, blow-up ratio of 2.5:1–3.5:1, and core melt temperatures of 200–230°C while skin layers are held 10–20°C lower to preserve seal integrity. Internal bubble cooling and layflat control are used to reduce gauge variation to within ±5%. Terminal products include cereal liners, cracker wrap, dry mix pouches, and biscuit inner wraps in 20–50 µm total gauge. Incompatibility arises when excessive slip additive carries from skin to core; slip concentrations above 0.10 wt% in the core can interfere with interlayer adhesion, so additive placement is restricted to the skin layers.
For dry food pouches and flexible packaging laminations, FTA-001 is extruded as a mono-layer blown film of 15–35 µm thickness, then corona-treated to 38–42 dyn/cm before adhesive or extrusion lamination to BOPET, BOPP, or metallized substrates. The formulation uses FTA-001 at 88 wt%, LDPE at 10 wt%, antiblock masterbatch at 1 wt%, and slip masterbatch at 1 wt%; if the film is printed, corona treatment is maintained immediately before the print deck to prevent surface energy decay below 36 dyn/cm. Compliance follows FDA 21 CFR 177.1520(c) for food-contact applications and EU Regulation (EU) No 10/2011 for migration; lamination converters also require ASTM D882-18 tensile and ASTM D1922-23 tear data for package integrity. The production process is high-stalk blown film extrusion with a die gap of 0.8–1.2 mm, blow-up ratio of 3:1–4:1, melt temperature of 195–215°C, and line speed of 60–120 m/min; the collapsed web is slit to roll widths and rewound with taper tension under 0.4 N/cm. Terminal product types include dry soup sachet inner webs, stand-up pouch lamination layers, and moisture-barrier liners for boxed dry mixes. Storage of the resin at relative humidity above 60% can introduce surface moisture, requiring hopper drying at 70°C for 2 h to prevent bubble surface defects and poor corona adhesion.
If Thin-Gauge Trash Liners Demand Downgauging Without Losing BUR Stability
Downgauging kitchen trash liners from 20 µm to 12 µm requires maintaining bubble stability at blow-up ratios above 3:1 while preventing splitty transverse-direction tear. Formulations for this performance envelope contain FTA-001 at 90 wt%, C6 LLDPE at 8 wt%, slip/antiblock masterbatch at 2 wt%, and polymer processing aid at 400–800 ppm. Processing on high-stalk lines with a die gap of 0.8–1.0 mm, melt temperature of 185–205°C, and blow-up ratio of 3.5:1–4.5:1 places the frost line at 6–10 die diameters to stabilize the bubble. Compliance for trash liners is assessed under EN 13592 and ASTM D4976-23; for retail food-contact potential, FDA 21 CFR 177.1520(c) may apply only if the film is not colored with non-compliant pigments. Downstream production includes inline perforation, drawstring insertion, and film-to-bag conversion at 120–250 cycles/min. Terminal products are 10–18 µm kitchen trash liners, compact bin liners, and retail pack can liners. The limiting process variable at 10 µm gauge is dart impact retention; published data for this exact configuration is limited, and trial runs should establish minimum acceptable ASTM D1709-16a dart impact before full-scale conversion.
Heavy-Duty Industrial Can Liner Film and Carbon Black Dispersion
Heavy-gauge industrial can liners use FTA-001 at 94 wt%, carbon black masterbatch at 5 wt%, and antioxidant masterbatch at 1 wt%, extruded at 50–150 µm thickness. Carbon black dispersion is the critical quality parameter: poor dispersion creates gels that become tear initiation points under loaded-waste conditions, so screw designs with dispersive mixing elements and 100–150 µm screen packs are required. Compliance for non-food refuse sacks follows EN 13592, ASTM D4976-23, and REACH substance restrictions; FDA 21 CFR 177.1520 is not applicable to this carbon-black-filled waste packaging. The production process uses a low-stalk or conventional blown film die with a die gap of 1.2–1.8 mm, blow-up ratio of 2:1–3:1, melt temperature of 200–240°C, and a collapsing frame with gusseting to produce side-gusseted tubing. Terminal product types include drum liners, contractor bags, rubble sacks, and industrial waste packer bags. Melt temperatures above 250°C should be avoided because oxidative degradation increases gel formation and reduces tear strength; hopper drying is generally not required for sealed resin, but open storage at relative humidity above 60% may require 70°C drying for 2 h.

ExxonMobil HDPE FTA-001 is a high-molecular-weight high-density polyethylene copolymer supplied for blown film extrusion. The manufacturer’s published technical data identify a nominal density of 0.950 g/cm³ determined according to ASTM D1505 and a nominal melt index of 0.05 g/10 min at 190°C/2.16 kg according to ASTM D1238. The high-load melt index at 190°C/21.6 kg is reported as 6.0 g/10 min, giving an HLMI/MI ratio of approximately 120. That ratio, combined with a bimodal molecular weight distribution, is characteristic of a resin that sustains bubble stability at thin gauge while retaining sufficient shear thinning for high-output extrusion. The grade is positioned for thin-gauge HDPE film structures in which stiffness, moisture vapor resistance, and downgauging capability govern material selection. Film properties depend on extrusion conditions; the tabulated values are nominal and should not be construed as lot-by-lot specification limits.
What Distinguishes FTA-001 from Conventional Unimodal HDPE Film Resins?
Differentiation begins with molecular architecture. Conventional unimodal HDPE film grades generally display a narrow molecular weight distribution, which forces a compromise between melt strength and extruder throughput. FTA-001 is produced with a bimodal molecular weight distribution in which a high-molecular-weight fraction contributes to melt strength and dart impact resistance, while a low-molecular-weight fraction provides shear thinning during extrusion. This permits the formation of stable bubbles at thinner gauges than unimodal HDPE resins of similar melt index.
The density of 0.950 g/cm³ places FTA-001 at the lower end of the HDPE density range. Compared with high-density film resins at 0.960–0.965 g/cm³, FTA-001 typically exhibits lower tensile modulus but higher dart impact and tear resistance. The product is classified as a hexene copolymer in the manufacturer’s technical literature. Hexene comonomer generates longer short-chain branches than butene, and the resulting tie-molecule population differs under slow crack loading. The practical consequence is that FTA-001 is generally preferred where a balance between stiffness and impact toughness is required, whereas higher-density HDPE grades are selected for maximum modulus or creep resistance.
Compared with linear low-density polyethylene film resins of similar thickness, FTA-001 provides higher secant modulus, lower elongation at break, and lower water vapor transmission rate. It is not a direct substitute for LLDPE in applications requiring high dart puncture or very high stretch; its use is favored in blown film structures in which tensile modulus, moisture barrier, and down-gauging are primary performance criteria.

On single-screw blown film lines, ExxonMobil HDPE FTA-001 is processed at melt temperatures of 204–216°C at the die lip. Melt temperature above 230°C may reduce bubble stability and promote localized gel formation. Die gaps from 1.2 mm to 1.5 mm are typical for low-stalk bubble configurations; blow-up ratios of 3.5:1 to 4.5:1 provide adequate transverse orientation without excessive film curl. The frost line height is commonly held at 7–10 die diameters depending on air temperature and internal bubble cooling. Barrier screws with L/D ratios of 25:1 to 30:1 and Maddock mixing sections are recommended for uniform melt temperature and dispersion of additive concentrates. The use of a melt pump may reduce output variation when blending regrind. Melt pressure at the die is generally controlled within the range specified by the die manufacturer; prolonged die pressure above 40 MPa indicates screen blockage or insufficient melt temperature.
| Parameter | Typical Range |
|---|---|
| Melt temperature at die lip | 204–216°C |
| Die gap | 1.2–1.5 mm |
| Blow-up ratio | 3.5:1–4.5:1 |
| Frost line height | 7–10 die diameters |
| Extruder L/D ratio | 25:1–30:1 |
| Drying time at 80°C, if required | 4 h |
Pre-drying is not normally required when pellets are handled in sealed containers. If the resin is exposed to relative humidity above 60%, surface moisture can produce bubble instabilities. In that case, drying at 80°C for 4 h in a desiccant dryer with a dew point of -40°C is a standard corrective measure. The resin should not be processed with copper-containing stabilizer packages or exposed to direct ultraviolet radiation during storage because photo-oxidative degradation can shift melt index and reduce film impact properties.
Capillary rheometry under 190°C shows a shear-thinning profile characteristic of bimodal HDPE film resins. The low-shear viscosity at 0.01 s⁻¹ is elevated relative to unimodal film grades of equivalent melt index, which contributes to bubble stability; the high-shear viscosity at 100 s⁻¹ is reduced, which limits extruder amperage. Processing aid concentrate addition at 200–400 ppm active fluoropolymer is typical for thin-gauge lines where melt fracture appears at high output. Addition above 800 ppm may cause slip-induced output variation and should be avoided unless validated on the target line.
If the Draw-Down Ratio Exceeds 4:1 on High-Stalk Lines
When high-stalk bubbles are used, the stalk height and draw-down ratio control the balance between machine-direction orientation and transverse-direction orientation. At draw-down ratios above 4:1, FTA-001 films show an increase in machine-direction tensile strength and a decrease in machine-direction Elmendorf tear measured under ASTM D1922; the transverse-direction tear increases because transverse orientation is reduced. The resulting anisotropy is especially visible in film below 12 µm, where dart impact measured under ASTM D1709 may fall by more than 20% relative to a balanced bubble when the frost line is not adjusted. Frost line height below 7 die diameters causes rapid crystallization of the high-molecular-weight fraction and destabilizes the bubble; frost line height above 10 die diameters reduces cooling rate and may lead to blocking.
For high-stalk operation with FTA-001, the internal bubble cooling exhaust should be set to maintain a stable stalk geometry. A stalk height of 8–10 die diameters is typically maintained for 25 µm film at a 4:1 blow-up ratio. When the draw-down ratio exceeds 5:1, the high-molecular-weight fraction can develop excessive machine-direction orientation, and the film may split along the machine direction during bag conversion. Published data for this exact configuration are limited; therefore, the response of the resin to extreme draw-down ratios should be established by trial on the target line.
FTA-001 is used in thin-gauge HDPE film applications including merchandise bags, industrial liners, and laminated structures. In blends with linear low-density polyethylene at 10–20 wt%, the resin contributes stiffness while the LLDPE phase increases dart impact; the blend ratio is adjusted according to end-use requirements and test values obtained under ASTM D1709 and ASTM D1922. In three-layer coextruded films, FTA-001 can be placed as the core layer or as the outer stiffness layer. When coextruding with sealant resins, the die temperature profile should be maintained within ±5°C to avoid viscosity mismatch at the layer interfaces. The use of post-industrial regrind is typically limited to 20 wt%; higher regrind levels may increase gel counts and reduce tear resistance.
A 25 µm film produced from a 0.950 g/cm³ HDPE of this class typically exhibits a water vapor transmission rate of 5–8 g/(m²·day) at 38°C/90% RH according to ASTM F1249. This barrier property supports replacement of thicker low-density polyethylene films with thinner HDPE structures. For food contact use, the resin is normally evaluated under U.S. FDA 21 CFR 177.1520 for olefin polymers. End users must verify conditions of use, extractive limits, and any applicable migration limits under EU Regulation 10/2011 or equivalent regional legislation. REACH compliance should be confirmed through the supplier’s safety data sheet.
Large-Diameter Air Rings and Internal Bubble Cooling Compatibility
The melt strength of FTA-001 permits the use of internal bubble cooling on dies above 250 mm. Dual-lip or multi-lip air rings with independently adjustable lower-lip and upper-lip apertures are recommended. Cooling air temperature should be maintained between 8°C and 15°C for high-output lines. On an 80 mm extruder with 30:1 L/D, a 300 mm die, and a 1.4 mm die gap, output rates of 180–220 kg/h are typical for this resin class. Maximum stable output is usually limited by bubble oscillation at high internal bubble cooling airflow rather than by extruder torque. During gauge transitions, the internal bubble cooling airflow should be adjusted before screw speed to avoid sudden changes in frost line height. Air ring clogging from low-molecular-weight additive bloom can reduce cooling efficiency; therefore, air ring maintenance intervals should follow the equipment manufacturer’s recommendations.
