On a 55 mm single-screw blown film extruder with a 30:1 L/D barrier screw and a dual-lip air ring, INZEA F09E is processed for perforated produce bags at a finished thickness of 18–35 µm. Pre-drying is required when the resin has been stored at relative humidity above 60%. A desiccant dryer set to 70°C for 4 h with a dew point below −40°C is the practical minimum before extrusion. The barrel profile is segmented from 150°C at the feed section to 185°C at the metering section. The adapter and die are held at 175–185°C. Bubble stability is maintained at a blow-up ratio of 2.0:1–2.5:1 and a frost line height within 1–2 die diameters. PLA-based flexible compounds exhibit lower melt strength than low-density polyethylene. Collapsing-frame tension must be kept below the warm-film yield point. Excessive web tension in the primary nip produces edge wrinkles that propagate into gauge bands later. A slip/antiblock masterbatch based on erucamide and silica is added at 0.3–1.0 wt% only when blocking is observed during roll storage. Masterbatch pre-dispersion on a twin-screw compounding line with 44:1 L/D is recommended; poorly dispersed slip migrates unevenly and reduces seal strength. The resulting haze is measured by ASTM D1003. An overload above 1.5 wt% can create visible surface defects. For fresh produce, the relatively high water vapour transmission rate of the film is tolerable and often beneficial because it reduces condensation inside the pack. Oxygen transmission is monitored against ASTM D3985 at 23°C and 0% RH. Perforation density is set by product respiration rate, not by film supplier data. Finished produce bags carrying a home compost claim are tested to a certification scheme such as TÜV Austria OK compost Home or AS 5810. EN 13432 alone is an industrial composting standard run at 58°C and does not prove ambient-temperature home compostability. A 12-week disintegration interval and at least 90% ultimate biodegradation within 180 days under ISO 14855-1 apply to industrial EN 13432 testing. Home compost schemes use lower temperatures and longer intervals. The terminal article is a perforated produce bag with a folded bottom seal or side weld, a folded lip, and a label that separately declares the certification body reference.
Vertical form-fill-seal conversion of INZEA F09E into reclosable freezer-to-compost pouches is governed by seal-initiation temperature and low-temperature impact resistance. Seal curves are generated on the target VFFS machine using ASTM F88/F88M rather than on a laboratory heat sealer. Jaw geometry, dwell time, and Teflon release layer each shift the measured seal strength. Seal initiation is generally observed at 85–95°C on properly dried film. Acceptable hot-tack strength is achieved only when the seal bars remain closed for 0.3–0.5 s. Seal-bar temperatures above 120°C cause visible shrinkage along the cross seal and produce pinholes because the PLA-rich phase softens rapidly past the crystallization window. Batch-to-batch variation in molecular weight can shift seal initiation by as much as 4°C, so incoming lot checks are required. To lower seal initiation, converters sometimes blend with 10–20 wt% polybutylene adipate terephthalate or another certified compostable copolyester. This shifts the initiation point down by approximately 8–12°C but increases blocking tendency. A zipper-reclosable profile made from the same home-compostable copolyester family is fused to the inside web at 105–115°C. The zipper flanges must be treated to a surface energy above 38 dyn/cm before sealing. If not, seal strength at the zipper junction drops below 2 N/15 mm and fails after repeated opening cycles. Because the final structure is no longer a monolayer, the entire pouch—including the zipper and adhesive layers—must be tested as an article under AS 5810 or a TÜV Austria OK compost Home scheme. EN 13432 industrial composting testing at 58°C does not establish a home compost claim. For frozen food contact, migration testing under EU Regulation 10/2011 is required when the pouches are sold inside the European Union. Overall migration must remain below 10 mg/dm² using simulants appropriate to the food type. Low-temperature impact resistance is the main technical risk. PLA-rich films may exhibit brittle failure below −20°C, and published data for this specific freezer-to-compost configuration is limited. Dart impact is measured according to ISO 7765-1 after conditioning at −18°C for 24 h. A minimum value should be established on the actual production line rather than inferred from ambient-temperature data. The terminal product is a printed zipper pouch with a tamper-evident tear notch, a zipper flange, and a home compost certification mark placed only after article-level testing is complete.
INZEA F09E can be used as a mono-layer overwrap for dry bakery goods and short-shelf-life snacks where moisture ingress control is secondary to optical clarity and dead-fold. The film is converted on a horizontal flow-wrap machine with rotary sealing jaws. The sealing temperature at the fin-seal wheel is kept between 90°C and 110°C. The wheel speed is reduced by 15–25% compared with biaxially oriented polypropylene to compensate for the narrower hot-tack window. Because PLA-based films have a lower moisture barrier than polyolefins, the water vapour transmission rate must be measured by ASTM F1249 at 23°C and 50% RH. For a 25 µm mono-layer film, published industrial values for general PLA film are broad and highly dependent on crystallinity, thickness, and storage humidity; converters must verify the exact grade on the target line. The film should not be used for moisture-sensitive snack products with a required shelf life beyond 4 weeks unless a thin barrier coating is applied. A polyvinyl alcohol or nanoclay dispersion coating below 5 wt% of total article weight may reduce water vapour transmission by 30–70% depending on coat weight and curing. Aroma barrier is another limitation. Volatile aroma compounds from cinnamon, citrus oil, or cocoa can partition into the PLA-rich phase and cause off-odour retention after pack opening. Barrier performance should be tested according to ASTM E398 or ISO 15106 using the actual aroma simulant, not only oxygen permeability. For bakery overwrap, the film’s dead-fold retention is assessed by a 90° bend recovery angle test derived from ASTM D2923. A lower recovery angle enables tighter fold-back seals on bread bags. The terminal product is a clear bread bag or pastry pillow pack with paperboard tray and fold-over ends. It is labelled for home compost disposal only if the final printed and adhesive-containing article passes AS 5810 or TÜV Austria OK compost Home requirements, not solely industrial EN 13432 testing.
Directly from slitting to a wide-web flexographic press, the e-commerce mailer application introduces surface treatment, ink chemistry, and peel-and-seal closure requirements that differ from food-pack converting. INZEA F09E film is corona-treated at 42–48 dyn/cm in-line before printing. Treatment below 38 dyn/cm produces poor water-based ink adhesion. Treatment above 52 dyn/cm can embrittle the surface and reduce heat seal strength. Water-based flexographic inks are specified because solvent-based and UV-cured systems may contain components that fail the heavy metals and ecotoxicity limits of the home compost certification scheme. The film is printed on a press with web tension controlled to 20–35 N per meter width. Tension above 50 N/m stretches the PLA film and creates registration drift. An opaque white base film or a printed outer layer is used because the mailer market does not require full transparency. Opacity is supplemented with a mineral filler masterbatch at 5–15 wt% in the film structure. The mailer is closed with a home-compostable pressure-sensitive adhesive tape, not with a standard acrylic hot-melt adhesive. Standard acrylic adhesives do not disintegrate within the required home compost disintegration period and can cause the final article to fail the certification scheme. The peel-and-seal release liner must also be compostable or removable before disposal. For e-commerce distribution, the filled mailer is subjected to burst testing according to ISO 2759 or ASTM D774. The film thickness is typically increased to 50–80 µm to meet puncture resistance under transport. Puncture resistance is measured with ASTM D3420 or EN 14477. This is a critical threshold because home-compostable films can exhibit lower resistance to sharp edges in corrugated shipping containers. The terminal product is a printed, self-seal mailer with a compostable adhesive strip, a peel-off liner, and markings that explain separate disposal of non-compostable labels if present.
INZEA F09E is converted into transparent or matte overwrap for compressed nonwoven hygiene products such as cotton pads, dry wipes, and compressed nonwoven packs intended for home-compostable secondary packaging. The film is processed on a high-speed flow-wrapper with heat-wire cut-off or hot-knife sealing at 170–190°C for the fin seal. Hot-knife sealing uses a Teflon-coated blade to cut and seal simultaneously. Blade temperature must be profiled because a blade above 200°C produces beaded edges. Dead-fold retention is important for tight tuck-in ends. The film’s fold recovery angle is evaluated by bending a 25 mm strip 180° and measuring recovery after 5 s under a 500 g load. A target recovery angle below 30° is used for hot-folded overwrap. This dead-fold behaviour allows tidy side gussets on lateral flow-wrap machines. The outer surface is printed with low-odour water-based inks. Ink odour is checked by panel testing or ISO 17299 where applicable because the packaged nonwoven article can absorb residual volatiles. Slip and release on the flow-wrap infeed are controlled with an erucamide-based slip agent at 0.2–0.6 wt%. Excessive slip above 0.8 wt% causes seal contamination and weakens the longitudinal seam below 1.5 N/15 mm. The material is tested for tensile elongation under ISO 527-3 at 23°C and 50% RH. Typical values for PLA-based flexible film fall between 200% and 400% in the machine direction, but the exact grade data must be confirmed with the supplier. For hygiene products, no food-contact migration testing applies unless the film touches skin during normal use. If direct skin contact is foreseeable, a toxicological assessment under REACH and, where relevant, EU Regulation 10/2011 is performed. Home compost labelling requires article-level testing under AS 5810 or a TÜV Austria OK compost Home scheme because EN 13432 industrial testing does not duplicate ambient compost conditions. The terminal article is a flow-wrapped bundle of nonwoven pads with printed registration marks, a tuck-in end seal, and a home compost disposal icon placed on the back panel.

INZEA F09E is a flexible film-grade polylactic acid (PLA) compound supplied in pellet form for blown and cast film extrusion. The product is intended for home compostable flexible packaging, organic waste collection liners, carrier bags, and overwrap applications where the TÜV Austria OK compost Home mark is required alongside industrial compostability under EN 13432:2000. The model designation F09E identifies the flexible film extrusion grade within the INZEA biopolymers range, which is commercialized for conversion into films with thicknesses typically between 15 µm and 60 µm. Published technical data for this grade list a melt flow index between 2–4 g/10 min at 190°C under 2.16 kg load according to ISO 1133-1:2022, a density of 1.24 g/cm³ according to ISO 1183-1:2019, and a melting range of 150–160°C by differential scanning calorimetry under ISO 11357-3:2018. Lot-to-lot variability in melt flow index is typically controlled within ±0.5 g/10 min; excursions outside this band have been observed to alter bubble stability and draw resonance on cast lines.
Pre-drying is the first critical control. Pellet moisture must be reduced below 250 ppm before melt processing because PLA ester linkages undergo hydrolytic chain scission at melt temperature. Drying in a desiccant dryer at 70°C for 4 h with a dew point of ≤-40°C is the minimum recommended condition; at warehouse relative humidity above 60%, drying should be extended to 6 h. Single-screw extruders with 30:1 L/D and a barrier screw having compression ratio 2.5:1–3.5:1 are typically used because the grade is supplied ready-to-process and does not require additional compounding. The barrel profile from feed throat to adapter is commonly set at 160°C, 170°C, 175°C, 180°C, and 175°C.
The melt temperature at the die must remain within 175–185°C, a processing window of ±5°C. Below 175°C, melt viscosity rises sufficiently to cause premature bubble solidification, machine-direction gauge bands, and elevated extruder backpressure. Above 185°C, random chain scission accelerates; at 220°C, intrinsic viscosity of PLA-based compounds can fall from approximately 1.2 dL/g to below 0.9 dL/g within 20 min, producing gel particles and reduced tensile strength. On blown film lines of 45 mm screw diameter, stable throughput is typically 60–80 kg/h at screw speeds of 60–90 rpm. Backpressure measured at the screen changer should remain between 80 bar and 140 bar; values below 80 bar may indicate screw wear or insufficient fill, while values above 140 bar suggest excessive filtration or low melt temperature.
| Parameter | Blown film | Cast film | Reference method |
|---|---|---|---|
| Pellet moisture after drying | ≤250 ppm | ≤250 ppm | ISO 15512:2019 |
| Melt temperature at die | 175–185°C | 175–185°C | thermocouple |
| Die gap | 0.8–1.2 mm | 0.6–1.0 mm | mechanical gauge |
| Blow-up ratio or draw ratio | 2.5:1–3.5:1 | 5:1–10:1 | dimensionless |
| Chill roll temperature | not applicable | 20–40°C | contact thermocouple |
| Maximum residence time | <15 min | <15 min | throughput calculation |
For blown film, blow-up ratio is maintained at 2.5:1–3.5:1, with frost line height 2–4 die diameters. Deviation below 2.5:1 creates thick edges and uneven gauge, while deviation above 3.5:1 causes bubble flutter and loss of orientation. On cast film lines, die-to-roll distance below 20 mm improves clarity and reduces neck-in. Purging with a low-viscosity biodegradable purge compound is required before shutdown; residual melt held above 190°C for more than 15 min darkens and generates acrid volatile compounds.
When film is drawn to 30 µm thickness and conditioned for 48 h at 23°C and 50% RH, tensile properties measured according to ISO 527-3:2018 fall within machine-direction tensile strength 25–35 MPa, transverse-direction tensile strength 20–30 MPa, machine-direction elongation at break 250–350%, and transverse-direction elongation at break 300–400%. Secant modulus at 1% strain is 600–900 MPa in the machine direction and 500–800 MPa in the transverse direction. Trouser tear strength determined by ISO 6383-1:2015 is 50–100 N/mm for a 30 µm film. Seal initiation temperature measured by ASTM F88/F88M-21 at 0.7 N/mm² seal pressure and 0.5 s dwell is 85–95°C; this is approximately 15–25°C lower than rigid PLA film and permits shorter jaw contact time on vertical form-fill-seal equipment. Water vapour transmission rate at 23°C and 85% RH measured according to ASTM F1249-20 is typically 100–200 g/m²·day for 30 µm film, comparable to other flexible PLA-based packaging films.
In the European Union, a compostable packaging claim under EN 13432:2000 requires demonstration of biodegradation, disintegration, compost quality, and ecotoxicity. Biodegradation is evaluated under ISO 14855-1:2012 at 58°C ± 2°C; a minimum of 90% conversion to carbon dioxide relative to the theoretical value must occur within 180 days. Disintegration is evaluated under ISO 16929:2021 or ISO 20200:2016; no more than 10% of the original dry mass may remain on a 2 mm sieve after 12 weeks. The final compost must satisfy plant growth tests under OECD 208 and heavy metal limits in Annex A of EN 13432:2000, including Cu 50 mg/kg, Zn 150 mg/kg, Ni 25 mg/kg, Cd 0.5 mg/kg, Pb 50 mg/kg, Hg 0.5 mg/kg, and Cr 50 mg/kg.
Home compostability certification under the TÜV Austria OK compost Home scheme is more restrictive because biological oxidation occurs at 20–30°C and must be completed within ≤365 days. The certification aligns with the testing principles of EN 17427:2022 and analogous national schemes such as AS 5810. INZEA F09E is formulated for this lower-temperature pathway; the grade also satisfies industrial compostability, making it suitable for packaging that may enter either home compost bins or municipal organic waste collection. The distinction is not trivial: many PLA grades that meet EN 13432:2000 at thermophilic temperatures do not completely degrade in home compost because their crystallinity and hydrolysis rate are too slow below 30°C. For food-contact packaging, the converter must verify that the final film meets Regulation (EU) No 10/2011 and US FDA 21 CFR for the intended food type and contact conditions. A supplier declaration of compliance is not a substitute for migration testing on the finished film, because processing aids, printing inks, and corona treatment can alter overall migration.
A direct substitution of rigid PLA film with INZEA F09E changes the mechanical failure mode from brittle fracture to ductile deformation. Neat PLA film tested under ISO 527-3:2018 commonly shows tensile modulus between 2000 MPa and 3500 MPa and elongation at break below 10%. PBAT-dominated flexible compostable films show tensile modulus below 200 MPa and elongation at break above 500%, but their renewable carbon fraction is commonly 20–40% by ASTM D6866-21. INZEA F09E occupies an intermediate position: modulus 600–900 MPa, elongation 250–350%, and renewable carbon above 50%. The lower seal initiation temperature against rigid PLA reduces heat-seal jaw temperature by 15–25°C and permits use on high-speed flow-wrappers where dwell times are below 0.3 s.
| Property | INZEA F09E | Rigid PLA film | PBAT-dominated blend | Test method |
|---|---|---|---|---|
| Tensile modulus, machine direction | 600–900 MPa | 2000–3500 MPa | 80–200 MPa | ISO 527-3:2018 |
| Elongation at break, machine direction | 250–350% | 5–15% | 500–800% | ISO 527-3:2018 |
| Seal initiation temperature | 85–95°C | 110–130°C | 80–95°C | ASTM F88/F88M-21 |
| Home compost certification | Yes | Often no | Usually yes | TÜV Austria OK compost Home |
| Renewable carbon fraction | >50% | >90% | 20–40% | ASTM D6866-21 |
For warehouse storage, pallets should remain in sealed original packaging at 10–30°C and relative humidity below 60%. Opened sacks exposed for more than 8 h at 23°C and 75% RH require re-drying at 70°C for 4 h before extrusion. The film is not intended for prolonged service above 50°C or for direct contact with high-moisture hot-filled products; hydrolysis of PLA ester linkages proceeds as a function of water activity and temperature. Avoid blending with amine-based additives, certain metal stearates, and unapproved epoxidized oils because nucleophilic residues can accelerate chain scission and may compromise home compostability. For printing, corona treatment is typically set to 38–42 mN/m; surface energy decays within 7 days under hot humid storage. Home compostability does not imply marine biodegradability or anaerobic digestion performance. If an oxygen barrier below 50 cm³/m²·day·atm is required, published data for uncoated F09E film in this configuration is limited, and a biodegradable barrier coating or lamination would be necessary.
