Technical and usage data summary for 3 oz (≈89 mL) polyethylene terephthalate (PET) single-use cups.

Property Typical Value Range Notes / Test Standard
Material Polyethylene terephthalate (PET) Common food-grade thermoplastic used for clear, lightweight cups.
Nominal Capacity 3 oz (approx. 89 mL) 85–95 mL Measured fill volume; usable volume may vary with rim design.
Typical Weight per Cup ≈ 2.8 g 2.2–3.6 g Depends on wall thickness and rim reinforcement.
Density (Specific Gravity) ≈ 1.38 1.34–1.40 Typical for PET at 23 °C.
Glass Transition Temperature (Tg) ~ 75 °C 70–80 °C Above Tg, material becomes softer; affects hot-fill performance.
Melting Point 250–260 °C 250–260 °C Processing window for injection/stretch-blow and thermoforming processes.
Tensile Strength (Yield) ~ 60 MPa 55–75 MPa Measured by standard tensile tests (e.g., ASTM D638 for plastics).
Elongation at Break ~ 100 % 50–200 % Varies with processing (orientation increases strength and elongation).
Wall Thickness (typical) 0.18 mm 0.12–0.30 mm Depends on forming method; tolerances ±0.02–0.10 mm by design.
Dimensional Tolerance (height / diameter) ±0.10 mm ±0.05–0.20 mm Typical for thermoforming or injection/stetch-molded cups; depends on tool and process control.
Clarity (Haze) Low haze; high transparency Haze <5% (typical) Excellent optical clarity for display; measured per ASTM D1003.
Thermal / Service Limits Safe for cold & ambient; limited hot-fill Recommended max short exposure: 60–70 °C Not suitable for boiling liquids or autoclave sterilization; may deform above Tg under load.
Barrier Properties Good CO2 barrier; moderate O2 barrier OTR and WVTR dependent on thickness & orientation Typical tests: ASTM D3985 (O2) and ASTM F1249 (water vapor).
Chemical Resistance Resistant to water, mild acids, and alcohols Not resistant to strong oxidizers Avoid prolonged exposure to strong bases/oxidizers and some solvents.
Recyclability PET recycling code: 1 Widely accepted in mechanical recycling streams where local programs exist.
Food Contact Compliance Conforms to common food-contact regulations when processed appropriately Manufacturing and post-processing must follow regulatory guidance for food-contact materials.
Usage Notes: Designed primarily for cold or ambient-temperature samples, tastings, and single-serve cold beverages. Not intended for repeated microwave or autoclave sterilization. For critical barrier or high-temperature applications, consider specialized liners or alternative materials.

Production Throughput vs Defect Rate by Line (3 oz PET Cups)

This chart compares production throughput (units per hour) and defect rate (%) across five production lines manufacturing 3 oz PET cups. Throughput values indicate the average output capacity observed during a typical production shift, while defect rates capture the percentage of cups rejected due to quality issues. Line E shows the highest throughput (1300 units/hr) combined with the lowest defect rate (0.9%), suggesting an optimized balance of speed and quality. Line D demonstrates the lowest throughput (800 units/hr) and the highest defect rate (3.0%), which flags both capacity and quality concerns. Line B has moderate capacity but a relatively elevated defect rate (2.3%), indicating potential process instability or equipment tuning issues. Line A and Line C show solid throughput (1200 and 1100 units/hr) with low defect rates (1.5% and 1.1%), representing balanced performance. Key takeaways: prioritize investigation on Line D to identify root causes—possible factors include tooling wear, material feed issues, or operator training gaps. Line B should undergo quality audits to reduce rejects without sacrificing throughput. Best practices observed on Line E (setup parameters, preventive maintenance cadence, operator practices) could be standardized and transferred to underperforming lines. Tracking these two dimensions together enables targeted interventions: increasing throughput alone is counterproductive if defect rates climb, while reducing defects at the expense of throughput may hurt overall output. Regularly updating this chart with shift-level or weekly data will help monitor trends, assess the impact of corrective actions, and support continuous improvement initiatives.
