Municipal organic waste diversion programmes impose simultaneous requirements on film liners: wet waste load retention at household temperatures, puncture resistance against mixed kitchen waste edges, and full disintegration under industrial composting conditions. INZEA F15C HT, a flexible polylactic acid compound with 50% renewable carbon per ASTM D6866 or ISO 16620-2, is processed into biowaste caddy liners where EN 13432:2000 is the governing harmonised standard. The compliance boundary for this application includes EN 13432:2000 clause 4.2.2, which requires at least 90% biodegradation within 180 days under ISO 14855-1 controlled composting; clause 4.2.3, requiring no more than 10% residue above 2 mm after 12 weeks; and clause 4.2.4, requiring no negative effects on compost quality or plant ecotoxicity. In blown-film conversion for caddy liners, the compound is metered at 88–95 wt% with 5–12 wt% poly(butylene adipate-co-terephthalate) and 1–2 wt% antiblock masterbatch. The PBAT fraction is raised toward the upper bound when gauge falls below 15 µm to compensate for notch-tear loss after perforation. No amine-containing compatibiliser is introduced because free amine species can accelerate hydrolytic chain scission in PLA at melt temperatures above 180 °C.
Pre-drying is conducted at 70 °C for 4–6 h with desiccant air at a dew point of −40 °C or lower to bring moisture below 250 ppm. Blown-film extrusion on a single-screw line with L/D 25:1 to 30:1 uses a barrel profile from 150 °C to 175 °C, die temperature 175 °C, die gap 0.8–1.2 mm, blow-up ratio 2.0:1–2.5:1, and line speed 20–40 m/min. At ambient relative humidity above 60%, drying dwell time is extended by 2 h because surface moisture uptake reduces bubble stability. Finished terminal products include 10 L and 20 L kitchen caddy liners, 80–120 L curbside collection sacks, and 20–25 µm perforated roll bags.
High-speed carrier bag conversion subjects compostable film to forces that are not fully captured by tensile yield data alone. The relevant compliance framework for retail carrier bags is EN 13432:2000 in the EU or ASTM D6400 in North America; mechanical performance is typically assessed by dart impact per ISO 7765-1 Method A or ASTM D1709 Method A. INZEA F15C HT is blended at 90–98 wt% with 0.5–1.5 wt% slip/processing aid and 0.5–2.0 wt% mineral antiblock. When tear propagation falls below 20 N/mm in Elmendorf testing per ISO 6383-2, PBAT is added at 5–10 wt%, but this lowers renewable carbon content and requires re-verification of the 50% renewable figure against ASTM D6866. The primary process conflict is the heat-seal window: seal initiation may occur near 85–95 °C, while jaw temperature above 105 °C induces film distortion, leaving a working window of 10–15 °C. Hot-tack strength is mapped on a J&B or Brugger HSG-C hot-tack rig before production because seal pop-open occurs when the hot-tack plateau is shorter than the bag ejection cycle.
Film production for this segment uses either blown-film or cast-film lines. Blown-film extrusion on a three-layer die is preferred when a PBAT-rich skin is coextruded over a PLA core to improve fold recovery; die gap is set at 0.8–1.2 mm, blow-up ratio 2.0:1–2.5:1, frost line 2–4 die diameters from the air ring, and die temperature 165–175 °C. Cast-film extrusion uses a chill roll at 15–25 °C and online corona treatment to 38–42 mN/m. Terminal finished product types include T-shirt bags at 20–30 µm, loop-handle retail bags, and lightweight frozen-food bags limited to dry goods.
The use of PLA-rich film in soil requires a clear separation between industrial compostability and soil biodegradation. EN 17033:2018 is the applicable standard for biodegradable mulch films used in agriculture and horticulture; it sets requirements for ecotoxicity, heavy metals, and soil disintegration. INZEA F15C HT is not specified as a neat soil-biodegradable resin because PLA hydrolysis slows below 25 °C, and soil temperatures in temperate climates remain below this threshold for long periods. For soil-biodegradable mulch film, the compound is blended at 40–70 wt% with 30–60 wt% soil-biodegradable aliphatic-aromatic copolyester and 2–5 wt% carbon black masterbatch. The exact blend must be certified under EN 17033:2018 as a finished film; published data for this specific configuration is limited, and certification is not transferred automatically from the base resin.
The downstream production process is blown-film extrusion with an oscillating haul-off to form flat lay widths of 1.2–1.8 m, die gap 1.0–1.4 mm, blow-up ratio 2.0:1–2.8:1, and film thickness 12–25 µm. Storage and transport require sealed packaging because PLA-rich film absorbs moisture and loses machine-direction stiffness above 60% relative humidity. Terminal finished products include black, white, and black/white agricultural mulch films for tomato, strawberry, and vine crops, with use regimes excluded from regions where soil temperature remains below 10 °C for extended periods unless independent field data support the claim.
Under EU Regulation (EU) No 10/2011, overall migration testing is performed on the finished food-contact film, not on the resin pellet alone. For produce bags and bakery films, the compliance stack includes EU Regulation (EU) No 10/2011 Annex II migration limits, the overall migration limit of 10 mg/dm², and Commission Regulation (EC) No 2023/2006 for good manufacturing practice in food-contact materials. In the United States, food-contact status for PLA-based films depends on an effective Food Contact Notification for the specific compound; PLA is not automatically covered by 21 CFR 177.1520. INZEA F15C HT is used at 95–100 wt% with 0–3 wt% processing aid and 0–2 wt% antiblock masterbatch; if a lower seal initiation is required, a coextruded PBAT-rich sealant layer is preferred over bulk modification to preserve stiffness and renewable carbon content.
The downstream production process for food-contact film is either cast extrusion or blown-film extrusion. Cast extrusion uses a die gap of 0.3–0.5 mm, chill roll temperature 15–25 °C, line speed 100–200 m/min, and inline corona treatment to 38–42 mN/m. Blown-film extrusion uses a blow-up ratio of 1.8:1–2.2:1 and filtered melt to reduce gel count; film thickness is 15–30 µm. Terminal finished products include fruit and vegetable roll bags, bakery films, bread bags, and perforated salad bags. The operational boundary is 40 °C hot-fill or higher: PLA-based film distorts above this temperature and must not be specified for hot-fill liquid contact.
E-commerce mailers manufactured from compostable PLA film require puncture resistance, seal integrity, and the ability to survive parcel sortation without longitudinal tear. The applicable compliance standard is EN 13432:2000 or ASTM D6400, with biodegradation testing per ISO 14855-1; for packaging designed for home compost, AS 5810 or NF T51-800 may be specified, but PLA responses under home-composting conditions must be verified because hydrolysis is slower below 30 °C. INZEA F15C HT is blended at 85–95 wt% with 5–15 wt% PBAT and 1–2 wt% slip/antiblock masterbatch. The PBAT fraction is raised to the upper bound for mailer gauges below 40 µm to improve puncture propagation resistance per ASTM D5748 or ISO 7765-2.
Downstream processing comprises blown-film extrusion at 30–50 µm thickness, die gap 0.9–1.2 mm, blow-up ratio 2.0:1–2.6:1, and surface corona treatment to 38–44 mN/m for print adhesion. Mailer conversion uses heat-jaw sealing at 85–100 °C with jaw pressure 0.2–0.4 MPa; impulse sealing is not recommended when the seal bar temperature exceeds 110 °C because it creates edge distortion and pinholes. Terminal finished products include poly mailers, garment bags, and document sleeves for loads below 5 kg. The operational boundary is puncture from heavy or sharp-edged contents: loads above 5 kg or irregular metal edges require puncture-resistant PBAT-rich films or an internal cushioned layer.
Published data for compostable shrink sleeves produced from PLA-based flexible film is limited, and converter trials must precede commercial specification. The applicable compliance framework for the finished sleeve as packaging is EN 13432:2000 or ASTM D6400; dimensional stability is assessed after shrink under controlled tunnel conditions. INZEA F15C HT is blended at 85–95 wt% with 5–15 wt% PBAT and 1–2 wt% slip agent to reduce blocking during orientation. The downstream process begins with cast film at 45–60 µm, followed by machine-direction orientation at 2.5:1–4.0:1 and transverse-direction orientation at 3.0:1–5.0:1 on a tenter frame. Shrink development occurs in a steam or hot-air tunnel at 60–70 °C; tunnel residence time is 5–10 s. Terminal finished product types include tamper-evident neck bands and short-body sleeve labels for low-contour containers. The operational boundary is high-contour packaging: shrink force is lower than PETG or PVC systems, and published data for this specific configuration is limited, so container profiling tests are required.

INZEA F15C HT is identified as a flexible compostable film grade within the polylactic acid (PLA) family, carrying a stated renewable carbon fraction of 50% when measured by ASTM D6866-22 Method B or ISO 16620-2:2019. The material is intended for cast and blown monolayer film extrusion rather than injection moulding or sheet extrusion. The renewable carbon value is an analytical result derived from biobased carbon-14 measurement; it is not a direct measure of compostability. Finished-film compliance is assessed separately under EN 13432:2000, ASTM D6400-21, or ISO 17088:2021. Because the material is a compounded PLA system, converter film properties depend on melt temperature, screw shear history, moisture content, blow-up ratio, frost-line height, and cast roll quench temperature. The grade designation F15C HT does not itself define melt flow rate or viscosity; converters must obtain lot-specific melt mass-flow rate, tensile, thermal, and optical data from the supplier certificate of analysis. Application targets generally include monolayer bags, overwrap, pouches, and lamination webs where industrial compostability claims are required.
Moisture control is the first limiting parameter. PLA-based compounds of this class are hygroscopic; residual moisture above 250 ppm before melting accelerates hydrolytic chain scission, reduces melt strength, and shifts melt flow rate upward. Desiccant-bed or desiccant-wheel dryers with inlet air dew point at or below -40 °C and hopper residence of 4 h at 70–80 °C are required. Dried resin should be conveyed with dry air and protected from atmospheric re-uptake. Hot-air ovens without dew point control are not suitable for this material because they cannot reliably reach the required residual moisture level.
Extrusion barrel temperatures from feed to metering are typically profiled from 160 °C to 190 °C, with melt temperature held below 200 °C; above this threshold random chain scission and lactide reformation become measurable. The practical melt-temperature window for flexible PLA film is narrow; deviations of ±5 °C can alter melt viscosity enough to change thickness uniformity and bubble geometry. Single-screw extruders with L/D 24:1 to 30:1 and compression ratio 2.5:1 to 3.0:1 are common for PLA film; high-shear barrier screws can generate excessive viscous heating and should be evaluated with pressure transducers and melt-temperature probes. Grooved feed sections are generally avoided unless barrel cooling is precisely controlled.
Rheological control is critical because PLA exhibits lower shear viscosity than many polyolefins at typical film-die shear rates. Melt flow rate is conventionally measured at 190 °C under 2.16 kg using ISO 1133-1. Higher melt flow rates improve flow but reduce bubble stability on blown film lines. Oscillatory rheometry under ISO 6721-10 or rotational parallel-plate methods should be used to track complex viscosity and storage modulus during start-up. An increase in loss factor above 180 °C may indicate additive degradation or plasticizer migration, and the melt temperature profile should be reduced accordingly.
Purging transitions from PVC, PET, or polycarbonate require full displacement with low-MFR LDPE or a commercial PLA purging compound. Residual PVC degrades to acidic species and may accelerate PLA degradation. Amine-based processing aids should be avoided unless the supplier confirms compatibility, because ester cleavage can be promoted under alkaline conditions. Residence time at melt should remain below 5 min; at 190 °C extended hold-up increases melt flow rate and reduces die-lip stability. On blown film lines, blow-up ratio is commonly held between 2.0:1 and 3.0:1; higher ratios increase transverse orientation but can destabilize the bubble. Frost-line height should be adjusted to maintain a stable neck and prevent blocking at the collapsing frame. Die temperatures are normally kept 5–10 °C above melt temperature to reduce premature solidification at lip edges.
At the winding stage, surface treatment of 38–44 mN/m is typically required for solvent-based or water-based ink adhesion; the dyne level decays over time and should be re-verified before printing. Published data for this specific INZEA grade configuration is limited; the ranges below are reference values for flexible PLA film systems and conventional film benchmarks from public polymer literature. They do not replace lot-specific certificate data.
| Material class | Renewable carbon by ASTM D6866 | Tensile modulus MD, ISO 527-3 | Elongation at break MD, ISO 527-3 | Haze, ASTM D1003 | Seal initiation, ASTM F88 | Moisture barrier, ASTM F1249 | Oxygen barrier, ASTM D3985 |
|---|---|---|---|---|---|---|---|
| Flexible PLA film, reference class for INZEA F15C HT | 50% specified | 1000–1800 MPa | 150–300% | 2–6% | 85–110 °C | Moderate to high WVTR | Low OTR relative to LDPE |
| Unmodified PLA film | 80–100% | 2500–3500 MPa | 3–10% | 1–3% | 80–100 °C | High WVTR | Low OTR |
| Fossil LDPE film | 0% | 150–300 MPa | 200–600% | 5–10% | 105–120 °C | Very low WVTR | High OTR |
| PBAT/PLA compostable blend | 20–50% | 200–800 MPa | 300–800% | 5–12% | 85–110 °C | Moderate WVTR | Moderate OTR |
INZEA F15C HT may fall within the flexible PLA film class, but formulation-specific modifiers can shift modulus, elongation, haze, and barrier values outside the listed bands. No direct correlation to finished film performance should be assumed without lot-specific ISO 527-3 tensile data and ISO 1133-1 rheology data.
Compostability certification for INZEA F15C HT requires independent conformity to the test framework of EN 13432:2000 or ASTM D6400-21. Biodegradation must reach at least 90% conversion to carbon dioxide, water, and biomass relative to a positive control within 180 days when tested by ISO 14855-1 or ASTM D5338-15. Disintegration requires that after 12 weeks in controlled composting, at least 90% of the original dry mass passes through a 2.0 mm sieve. Ecotoxicity testing uses higher plants and evaluates germination and biomass relative to blank compost; no adverse effect on compost quality is permitted. Heavy metal concentrations must remain below the specific thresholds for zinc, copper, nickel, cadmium, lead, mercury, chromium, molybdenum, selenium, arsenic, and fluorine.
The 50% renewable carbon claim is separately measured by ASTM D6866-22 Method B or ISO 16620-2:2019 and should not be conflated with compostability. Unmodified PLA can carry biobased carbon above 80%, while some PBAT-containing compostable films may carry lower biobased carbon because PBAT is frequently petrochemically derived. Renewable carbon accounting does not certify that the finished article will disintegrate in home compost conditions; converters must verify whether the grade carries industrial compost certification only or also home compost approval, because home compost temperatures are lower and require separate validation.
Industrial composting conditions are typically maintained at 58 ± 2 °C with 50–60% moisture. PLA requires hydrolysis before microbial mineralization, so the lag phase may be longer than for starch-based films. Degradation rate also depends on film thickness; sections above 100 µm can require longer than the standard test interval unless the formulation is specifically designed for thick-film disintegration. Food-contact status is not established by EN 13432. Where direct food contact is intended, migration testing under Regulation (EU) No 10/2011 or FDA 21 CFR 177.1630 is a separate regulatory requirement and must be completed on the finished film structure.
Substitution of INZEA F15C HT for low-density polyethylene in a flexible web changes the permeability balance and thermal sealing behaviour. PLA-class films generally show higher water-vapour transmission than LDPE and lower oxygen transmission. Barrier performance must be measured on the specific film gauge by ASTM F1249 for WVTR and ASTM D3985 for OTR. Published values for PLA film vary widely with plasticizer content, crystallinity, and orientation, so generic permeability figures are not a substitute for lot-specific measurement. A barrier coating or metallization is often required for high-moisture food packaging.
Heat seal initiation for flexible PLA film commonly occurs between 85 °C and 110 °C when tested by ASTM F88, whereas LDPE seal initiation is usually near 110 °C. The PLA seal window is typically narrower; dwell time and jaw pressure must be controlled to avoid seal edge thinning. Unlike LDPE, PLA-based films have lower elongation recovery and may crease or tear more readily at high line speeds if tension is not controlled. Dart drop impact by ASTM D1709 is typically lower for flexible PLA than LDPE unless the film is laminated or blended. Coefficient of friction by ISO 8295 may be higher for PLA unless slip additives are compounded into the film. Static charge retention is also different from polyolefins; static elimination may be required on high-speed bag lines.
Compared with PBAT-rich compostable films, the PLA-based F15C HT class provides higher tensile modulus and gloss, but may require blending or lamination for high tear strength and dart impact resistance. Compared with unmodified PLA film, the flexible designation indicates that elongation at break has been raised substantially, at the expense of tensile modulus and barrier symmetry. Flexographic and gravure inks formulated for polyolefins often do not adhere to PLA surfaces; water-based or bio-based ink systems and primers designed for polar PLA surfaces are used. Lamination adhesives must be screened not only for bond strength but also for compatibility with the compostability certificate of the full structure.
On a production bag line running at 120 cycles/min with hot-bar sealing, seal initiation temperature and dwell should be derived from ASTM F88 seal-strength curves; dwell below 0.5 s frequently produces weak seals, while dwell above 1.5 s can induce edge thinning and film puckering. Seal-bar temperature uniformity should be checked with a calibrated thermocouple array because PLA has a narrow melt transition at the seal interface. Corona treatment at 38–44 mN/m is typical for print adhesion but must be re-verified before ink changes. Slip and antiblock additives are consumed during regrind recycling; regrind levels above 20% may reduce coefficient-of-friction stability and increase blocking tendency. INZEA F15C HT should be stored in original packaging at 15–30 °C and 20–50% RH; opened bags must be re-dried before processing. Avoid prolonged exposure to ambient humidity above 60% RH, and do not dry this PLA grade with uncontrolled hot-air ovens. LDPE waste regrind is not compatible with PLA; separation of scrap streams is mandatory.
