In high-cavitation lid tooling, Luminy L130 is pre-dried in a desiccant dryer with a dew point no higher than −40 °C and a supply air temperature of 80 °C for 4 h, reducing residual moisture to <250 ppm before plastication. Barrel zones for thin-wall lids are typically set from feed to nozzle at 180 °C, 200 °C, 210 °C, 220 °C, and 230 °C, with the nozzle held at 220–230 °C and the hot-runner manifold kept at 225–235 °C. Actual settings are adjusted against screw recovery time and shear heating because residence-time distribution in 16-cavity and 32-cavity hot-runner systems can shift melt viscosity downward; a barrel residence time longer than 10 min at 230 °C typically raises the melt flow index and lowers pressure drop at the gate. Mold temperature is the dominant process variable for high-heat lid performance: the grade is processed at 95–110 °C, and an oil-heated mold with ±2 °C uniformity is preferred because pressurized water above 100 °C creates uneven cooling and differential shrinkage across the lid stack. Injection velocities for lid cavities with a wall thickness of 0.6–1.0 mm are typically 250–400 mm/s, and switch-over from velocity to pressure control is set at 95–98 % of fill volume to avoid peak cavity pressures above 80 MPa at the gate. Clamp force is calculated from projected area at 8–10 kN/cm², with mold breathing observed below 6 kN/cm² on lid stacks exceeding 32 cavities. The terminal product is a disposable hot beverage lid intended for brief contact with beverages at 85–95 °C; dimensional acceptance is commonly set at a maximum out-of-round deformation of 1.0 mm across the drinking aperture after thermal conditioning per ISO 75-2 method B. Food contact compliance is not assumed from the resin alone; migration testing under EU Regulation 10/2011 with the actual closure geometry and sealing layer is required, and FDA clearance must be verified against the grade-specific Food Contact Notification rather than generic PLA statements.
When L130 replaces an amorphous PET grade in a single-serve capsule line, the wall section at the frustum sidewall is maintained between 0.8 mm and 1.2 mm to balance fill pressure and crystallinity development. A valve-gated hot-runner drop with a gate diameter of 0.8–1.2 mm is used because edge gates produce excessive shear and local molecular weight loss at the high injection velocities needed for thin sidewalls. The mold is heated to 100–120 °C; at temperatures below 100 °C, the sealing flange and sidewall often remain amorphous, which lowers dimensional stability when the capsule is exposed to brewing water at 88–95 °C. Injection velocity is set between 200 mm/s and 350 mm/s, with peak cavity pressure limited to 70–90 MPa to prevent flash at the split line. The critical terminal defect is sealing flange warpage; a maximum flatness deviation of 0.3 mm across the flange plane is required for capsule piercing and seal integrity, measured with a three-dimensional optical scanner after conditioning at 50 °C for 24 h. Thermal properties are verified by differential scanning calorimetry per ISO 11357-3; a non-isothermal crystallinity of 30–40 % is a useful in-mold quality indicator, but published data for this specific L130 capsule configuration is limited. PLA does not provide the oxygen and water vapor barrier required for long shelf-life single-serve capsule bodies; therefore the processor must specify an external barrier coating, inner liner, or secondary package and must not rely on L130 as a monomaterial barrier. Migration testing under EU Regulation 10/2011 is required with the final capsule assembly, using coffee and brewing-water simulants specified for fatty and aqueous food contact; FDA clearance must come from a grade-specific Food Contact Notification.
| Application segment | Wall thickness range | Mold temperature set zone | Injection velocity | Critical quality criterion | Validation standard |
|---|---|---|---|---|---|
| Hot beverage lids | 0.6–1.0 mm | 95–110 °C | 250–400 mm/s | Aperture-zone warpage ≤ 1.0 mm | ISO 75-2 method B |
| Single-serve capsule body and flange | 0.8–1.2 mm | 100–120 °C | 200–350 mm/s | Sealing flange flatness ≤ 0.3 mm | ISO 11357-3 |
| Hot-fill dairy cups | 0.8–1.2 mm | 100–110 °C | 250–400 mm/s | Rim shrinkage ≤ 0.8 % after hot fill | ISO 306 |
| Portion cups | 0.7–1.0 mm | 35–60 °C cold fill; 110 °C hot fill | 300–500 mm/s | Short-shot elimination at ≤ 80 MPa peak cavity pressure | ISO 1133-1 |
| Cosmetic compact bases | 1.0–1.5 mm | 75–100 °C | 150–250 mm/s | Dimensional stability after oil contact | EC 1223/2009 |
Thermal warpage in rectangular hot-fill dairy cups is governed by crystallization shrinkage anisotropy between the gate region and the far-end rim. For L130, a mold temperature of 100–110 °C is required to develop sufficient crystallinity before ejection; below this range, hot-fill exposure at 80–90 °C softens the rim and produces visible ovalization after capping. The cup sidewall is typically designed at 0.8–1.2 mm, and the gate is placed off-center or in the side wall to shift the weld line away from the highest hoop-stress zone. Cavity pressure monitoring is used to hold peak pressure between 60 MPa and 85 MPa; upstream pressure variation greater than ±5 MPa across cavities produces differential packing and post-fill shrinkage. Shrinkage is measured per ASTM D955 after 24 h conditioning at 45 °C; rim shrinkage above 0.8 % is a rejection trigger for hot-fill dairy cup applications. Vicat softening temperature is measured per ISO 306 and heat deflection temperature per ISO 75-2 method B; both should be generated from conditioned specimens because residual moisture and incomplete crystallinity reduce the values. The terminal product is a single-serve dairy dessert or cream portion cup intended for hot filling at 80–90 °C; contact with liquid dairy emulsions requires migration testing under EU Regulation 10/2011 using the actual fat phase, and FDA clearance must be grade-specific.
The primary cycle-time constraint in 32-cavity portion cup molds is the interaction between thin-wall freeze-off and crystallinity development. Portion cup walls are specified at 0.7–1.0 mm, which requires injection velocities of 300–500 mm/s to complete fill before the melt front freezes at the mold wall. If the mold is held at 110 °C for hot-fill condiments, the frozen layer forms more slowly than in a cold mold, but the part must still be cooled sufficiently for ejection without gate-stringing or rim distortion. L130 should not be processed below 0.7 mm wall thickness without mold-flow simulation and high-speed injection units because short shots become the dominant failure mode. For cold-fill portion cups used for sauces and dressings, mold temperature can be reduced to 35–60 °C to shorten cycle time, but this sacrifices the high-heat crystalline network and is not acceptable for hot-fill sauces above 70 °C. The terminal product is a thin-wall portion cup for condiments, sauces, or single-serve cold dressings; food contact compliance follows EU Regulation 10/2011 and the applicable FDA Food Contact Notification for the specific cup geometry. Melt-flow stability is checked by ISO 1133-1 at 210 °C with 2.16 kg load; a shift in melt flow index by more than 15 % after 10 min residence in the barrel indicates thermal degradation and requires barrel temperature reduction or screw-speed adjustment.
Oil and powder contact in thin-wall cosmetic compact bases imposes dimensional stability requirements that differ from food-contact parts. The base and lid are typically injection-molded at 1.0–1.5 mm wall thickness, with mold temperature held between 75 °C and 100 °C to balance surface gloss, crystallinity, and ejection. Injection velocity is reduced to 150–250 mm/s because the slightly thicker wall allows lower shear conditions; excessive velocity produces jetting streaks and weld-line visibility on the show surface. The terminal product is a renewable-content compact or jar base for dry powder and anhydrous oil formulations; compatibility testing under EC 1223/2009 is required with the finished formulation, particularly for ester-based oils and fragrances that may swell amorphous PLA regions over time. Published data for this specific L130 cosmetic configuration is limited. Processors should avoid aggressive alkaline cleaning agents with pH above 9 on mold surfaces because PLA hydrolytic degradation accelerates under alkaline conditions. Batch-to-batch dimensional stability is tracked by ISO 291 conditioning and linear measurement after 48 h at 23 °C and 50 % RH; warpage above 0.5 mm across the closure plane is a rejection criterion.
Disposable cutlery produced from L130 is processed with melt temperatures of 190–220 °C and mold temperatures of 95–110 °C; the high-heat grade reduces deformation in hot soup contact, but published data for this specific cutlery configuration is limited.

Luminy L130 High Heat Thin Wall Injection Molding PLA is a semicrystalline polylactide grade supplied by TotalEnergies Corbion for thin-wall rigid packaging, single-serve food-contact articles, and high-temperature short-cycle moulding operations. The grade is identified on lot certificates by melt flow rate, density, residual lactide, and residual moisture content. The L130 designation distinguishes this material from standard amorphous PLA grades such as Luminy L105 and from impact-modified PLA grades: L130 increases heat deflection temperature through controlled crystallization of a high L-lactide optical purity backbone rather than through mineral filler addition. Consequently, the material retains translucency in thin sections while shifting the practical upper service temperature beyond the softening range of conventional PLA.
The primary application envelope includes thin-wall cups, portion packs, lids, cutlery, and single-serve beverage capsules where parts are exposed to hot-fill temperatures, microwave reheating, or dishwasher cleaning. The grade is not intended for retort sterilization above 120 °C or for continuous load-bearing service above its heat deflection threshold. Published data for high-speed, multi-cavity moulds with wall thickness below 0.4 mm is limited; process capability must be verified on the target tool and hot-runner configuration.
The balance is achieved by accepting a lower melt flow rate than standard injection moulding PLA in exchange for a higher degree of crystallinity after moulding. The grade exhibits shear-thinning behaviour that assists filling of narrow flow channels, but the processing window is narrower than that of amorphous PLA. The following values are representative of the manufacturer technical data sheet and are not independent specification limits.
| Property | Test method | Typical value |
|---|---|---|
| Melt flow rate | ISO 1133-1:2022, 210 °C, 2.16 kg | 20 g/10 min |
| Density | ISO 1183-1:2019 | 1.24 g/cm³ |
| Tensile strength at break | ISO 527-2:2012, type 1A | 60 MPa |
| Tensile modulus | ISO 527-2:2012, type 1A | 3.5 GPa |
| Elongation at break | ISO 527-2:2012 | 3–4% |
| Charpy notched impact strength | ISO 179-1:2010 | 3.5 kJ/m² |
| Heat deflection temperature | ISO 75-2:2013, method B, 0.45 MPa | 85 °C |
| Vicat softening temperature | ISO 306:2022, A50, 10 N | 95 °C |
| Melting temperature | ISO 11357-3:2018 | 175 °C |
The 85 °C heat deflection temperature under 0.45 MPa is sufficient for hot-fill liquids near 80 °C and for dishwasher exposure on the upper rack, but it does not create a retortable material. The modulus of 3.5 GPa supports wall thinning in rigid containers, while the low notched impact strength of 3.5 kJ/m² requires radiused corners and avoidance of sharp snap-fit undercuts. The melting temperature of 175 °C allows melt preparation at lower barrel temperatures than amorphous PET while retaining a practical crystallization plateau.
Luminy L130 is hygroscopic and must be dried before melt processing. A desiccant dryer set at 80 °C for 4 h is typically sufficient to reduce pellet moisture below 250 ppm as determined by ISO 15512:2019. Moisture above 400 ppm accelerates hydrolysis during plastication, producing molecular weight loss, splay, nozzle drool, and reduced heat deflection temperature on moulded parts. Storage in moisture-barrier packaging is required when ambient relative humidity exceeds 60%, and open containers should be returned to drying within 24 h.
Barrel temperature profiles on production-scale injection moulding machines commonly range from a rear zone of 180 °C through a front zone of 215 °C, with a nozzle set point near 210 °C. Melt temperature should not exceed 240 °C, because thermal degradation accelerates rapidly above that threshold and generates lactide deposits on mould vents and hot-runner components. Residence time at 230 °C should remain below 10 min; longer hold times shift melt flow and reduce mechanical properties.
Mould temperature has a decisive effect on final heat resistance. A mould temperature of 90–100 °C is required to develop the semicrystalline morphology that produces the 85 °C heat deflection temperature. Lower mould temperatures of 25–40 °C yield faster cycle times but result in largely amorphous parts with heat deflection behaviour near that of standard PLA. In thin-wall tools with hot-runner systems, gate freeze-off can occur when manifold temperature drops below 220 °C, because crystallization initiates in stagnant melt regions. Production experience indicates that hot-runner temperature uniformity is more critical for this grade than for amorphous PLA grades with lower crystallization rates.
Injection speed should be adjusted to fill the thinnest section before melt front solidification. For wall thickness below 1.0 mm, slower filling produces premature cooling at the flow front and visible knit-line weakness. Back pressure of 0.5–1.0 MPa and screw recovery speeds that avoid excessive shear heating are recommended. Lot-to-lot melt flow variation of approximately ±2 g/10 min can shift filling pressure in sections below 0.5 mm; processors should monitor filling work and switch-over pressure rather than relying only on screw position.
Single-serve beverage capsules and thin-wall cutlery represent the most demanding production environments for L130. In these applications, the material is often processed in electric injection moulding machines with screw diameters from 25 mm to 40 mm and L/D ratios from 20:1 to 24:1. The grade is suitable for hot-fill lids and portion packs that must survive brief contact with liquids at 80–90 °C, but continuous service under mechanical load at the upper heat deflection threshold is not recommended. For cutlery, the high modulus provides rigidity, while impact resistance must be managed through part geometry and avoidance of thin feather edges.
Published data for this specific configuration in ultra-thin-wall closure moulding below 0.4 mm is limited. Process development should establish the relationship between mould temperature, hold pressure, and part crystallinity on the target tool before full production release.
L130 differs from standard injection moulding PLA such as Luminy L105 in melt flow and heat resistance. Standard L105 is specified at approximately 60 g/10 min under the same 210 °C and 2.16 kg conditions, with a heat deflection temperature near 55 °C under 0.45 MPa. L130 lowers melt flow to approximately 20 g/10 min and raises heat deflection temperature to 85 °C. This trade-off means L130 is less suited to very long, extremely thin flow paths but better suited to hot-fill and dishwasher-heated parts. Impact-modified PLA grades offer higher notched Charpy values, often above 8 kJ/m², but they typically sacrifice heat resistance and modulus relative to L130.
Compared with amorphous PET, L130 processes at melt temperatures roughly 50 °C lower and does not require the 170 °C drying and high barrel temperatures associated with PET injection moulding. Bio-based carbon content of polylactide feedstock is commonly above 95% as measured by ASTM D6866-22, whereas fossil-based PET contains no measurable biogenic carbon. The lower processing temperature and bio-based origin are significant differences, but PET remains superior in barrier performance and continuous high-temperature resistance above 100 °C. L130 should not be considered a drop-in replacement for polypropylene in applications requiring high elongation, repeated flexing, or impact-dominated loading.
Moisture re-absorption after drying is a boundary condition for stable processing. Pellets held in open ambient air at 60% relative humidity can re-absorb enough moisture within 24 h to reduce melt viscosity and increase the risk of splay. Processors should use closed hopper systems with dry air or nitrogen blankets for extended runs. Regrind content up to 20 wt% can be used if the regrind is dried, free from polyolefin contamination, and generated from clean scrap. Higher regrind fractions shift melt flow upward and reduce heat deflection temperature by lowering the crystallizable molecular weight fraction.
L130 is incompatible with contaminated waste streams containing polypropylene or polyethylene; even small concentrations can cause delamination, weld-line weakening, and loss of translucency. Colored masterbatches must use PLA-compatible carriers. Strong alkalis, oxidizing acids, and prolonged steam above 100 °C degrade the polyester backbone. The material is not intended for medical implantation or for direct contact with strong solvents such as chlorinated hydrocarbons and aromatic oxygenates.
Regulatory compliance for food-contact use requires grade-specific documentation. Overall migration testing under EU Regulation 10/2011 is typically performed according to EN 1186-1:2002 with appropriate food simulants. United States clearance must be confirmed against the relevant Food Contact Notification or threshold-of-regulation determination for the specific grade and use condition. The following matrix summarizes the compliance framework; it does not replace a certificate of compliance for a specific production lot.
| Regulatory standard | Scope | Typical status |
|---|---|---|
| EU Regulation 10/2011 | Plastic materials and articles intended to contact food | Overall migration tested to EN 1186-1:2002; grade-specific declaration required |
| FDA 21 CFR 175.300 | Resinous and polymeric coatings | Confirm Food Contact Notification or threshold-of-regulation clearance for the specific grade |
| REACH EC 1907/2006 | Registration, evaluation, authorisation of chemicals | SVHC content below 0.1 wt% per lot documentation |
| RoHS 2011/65/EU | Restriction of hazardous substances in electrical and electronic equipment | Lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE below maximum concentration values |
| ASTM D6866-22 method B | Biobased carbon content | Typically above 95% biobased carbon for PLA feedstock |
Luminy L130 should be stored in original sealed packaging at temperatures below 40 °C and away from direct sunlight. Opened material should be re-dried before processing if the storage interval exceeds 4 h in uncontrolled humidity. Processors should maintain lot-level records of melt flow rate and residual moisture because these two variables exert the strongest influence on thin-wall filling consistency and crystallization behaviour.
