| Parameter | Typical Value / Range | Measurement / Test Method | Notes / Industry Guidance |
|---|---|---|---|
| Nominal Capacity | 350 mL | Volumetric fill at 20°C | Standard beverage nominal size; tolerance listed separately. |
| Volume Tolerance | ±2% (typical) | Volumetric accuracy test per production line calibration | Common manufacturing target to ensure fill accuracy and labeling compliance. |
| Bottle Weight | 9 – 18 g (depending on lightweight design) | Gravimetric measurement (single bottle) | Weight varies by wall profile, base design, and required pressure rating. |
| Wall Thickness | 0.25 – 0.60 mm (nominal sections) | Caliper or profile scanner | Optimized thickness balances material use, strength and blow moldability. |
| Material | PET (Polyethylene terephthalate), food-grade | Resin certificate & FTIR / DSC for verification | Commonly meets EU & FDA food-contact requirements when using approved resin. |
| Neck Finish | Common finishes: 28-400 / 28-410 (metric threads) | Dimensional gauge per finish spec | Choice depends on cap type (screw cap, sport cap); specify finish for closures compatibility. |
| Manufacturing Process | Injection Stretch Blow Molding (ISBM) or Extrusion Blow Molding (EBM) | Process documentation and machine recipe logs | ISBM typical for lightweight, high-clarity bottles; EBM used for some custom shapes. |
| Typical Cycle Time | ~1.5 – 4.0 seconds per cavity (varies by machine and mold) | Production line throughput records | High-output lines with multi-cavity molds achieve faster effective rates. |
| Mechanical Strength (Tensile) | Tensile strength ~55 – 75 MPa (dry PET, ISO 527) | Tensile testing (ISO 527) | Property depends on resin grade and orientation from stretch-blow process. |
| Pressure / Carbonation Resistance | Typically rated up to 4 – 6 bar for carbonated beverages | Hydrostatic pressure / burst tests | Design and base geometry determine safe working pressure and safety margin. |
| Thermal / Heat Resistance | Short-term exposure up to ~70°C; HDT ~70–80°C | Heat deflection test; practical hot-fill trials | Not suitable for true retort processes (>100°C). Hot-fill requires design validation. |
| Oxygen Transmission Rate (OTR) | ~0.5 – 2 cm³/m²·24h·atm (typical PET bottle wall equivalents) | OTR testing adapted for bottle geometry | Coatings or barrier liners (e.g., PVOH) can substantially improve OTR for sensitive products. |
| Recycled Content (rPET) | Common blends 0 – 30% for clear output; up to 100% possible with adjustments | Mass-balance reporting & rPET assay / documentation | Higher rPET may affect clarity and mechanical properties; regulatory traceability required. |
| Regulatory / Food Safety | Compliant when using approved food-grade PET (EU/FDA guidelines) | Certificates of conformity; migration testing if required | Resin and additives must meet regional food-contact regulations (e.g., EU No. 10/2011, FDA 21 CFR). |
| Surface Finishing & Decoration | Hot-stamping, offset printing, shrink-sleeve labeling, sleeve-printable | Adhesion and abrasion tests post-decoration | Decoration method should be selected considering production rate and barrier/coating compatibility. |
| Typical Applications | Still water, flavored water, non-retort juices, energy drinks, cold-brew coffee | Application suitability assessment | Not ideal for prolonged high-temp sterilization; excellent for cold & chilled beverages. |
| Quality Control Checks | Dimensional checks, visual inspection, leak test, pressure test, weight control | In-line QC and batch sampling per AQL standards | Statistical process control commonly used on high-volume lines to maintain consistency. |
| Tooling Lead Time (Mold) | Typical 4–8 weeks for standard molds; 8–16+ weeks for complex multi-cavity tooling | Tooling project schedule | Times vary with complexity, customization, and sample approval cycles. |
