I’m a China-based Manufacturer focused on supplying dependable China 8oz PET Plastic Bottles for cosmetic, food, and beverage brands. You’ll find our bottles light-weight, crack-resistant, and compatible with standard capping systems, making filling lines smooth and downtime low. We source virgin PET resin, ensure clear transparency, and offer consistent wall thickness to preserve product aesthetics and shelf-life. Our 8oz PET bottles come in multiple neck finishes and spray/flip-top options, with options for UV protection and custom labeling. I’ve built tight QA processes, from incoming resin checks to final packaging, so you can reduce rejects and simplify your logistics. Minimum order quantities are friendly for pilot runs, and lead times are short because we’re a dedicated China Manufacturer with scalable production. I’m ready to discuss your decoration, labeling, and regulatory needs, and provide competitive pricing, sample availability, and reliable shipping to your destination.

| Specification | Standard (Straight) | Slim (Tall) | Wide-Mouth | Test / Notes |
|---|---|---|---|---|
| Nominal Capacity | 8 oz (≈ 237 ml) | 8 oz (≈ 237 ml) | 8 oz (≈ 237 ml) | Measured fill ≈ 235–240 ml (filling tolerance dependent on cap & filler) |
| Typical Empty Weight | 11 g | 9 g | 13 g | Weights reflect common wall designs for still-water bottles |
| Overall Height (±1.0 mm) | 145 mm | 155 mm | 130 mm | Dimensional tolerance typically ±0.5–1.5 mm |
| Max Diameter | 56 mm | 50 mm | 64 mm | Measured at widest body point |
| Neck Finish (outer thread / closure) | 28 mm PCO-style (common) | 28 mm | 38 mm (wide-mouth) | Closures: screw caps, tamper bands; verify closure spec with filler |
| Usable Opening (inner diameter) | 18–20 mm | 18–20 mm | 34–36 mm | Critical for filling/nozzle compatibility |
| Typical Wall Thickness | 0.45 mm (avg) | 0.40 mm (avg) | 0.50 mm (avg) | Thickness varies by preform & stretch ratio |
| Material | Polyethylene Terephthalate (PET, injection stretch-blow molded) | Material density ≈ 1.38 g/cm³ | ||
| Recyclability | Recyclable (PET, commonly assigned resin identification code 1) | Local recycling streams and labeling vary by market | ||
| Glass Transition / Service Temp | Tg ≈ 70–80 °C; recommended service up to ≈ 60 °C for short periods | Do not expose to prolonged heat or hot-fill >60 °C without evaluation | ||
| Melting Point | ≈ 250–260 °C (polymer softening occurs lower) | Processing: ISBM or EBM depending on preform & tooling | ||
| Oxygen Transmission Rate (OTR) | ≈ 2.0 cc/m²·day | ≈ 2.5 cc/m²·day | ≈ 1.8 cc/m²·day | Test: ASTM D3985 (typical @ 23 °C, 0% O2 or specified RH) |
| Water Vapor Transmission Rate (MVTR) | ≈ 0.8 g/m²·day | ≈ 1.0 g/m²·day | ≈ 0.7 g/m²·day | Test: ASTM F1249 (conditions vary; typical @ 38 °C, 90% RH) |
| Burst / Internal Pressure Rating | ~3.5 bar (50.8 psi) | ~3.0 bar (43.5 psi) | ~4.0 bar (58.0 psi) | Depends on bottle shape, base design and wall gauge; test per in-house protocol |
| Manufacturing Method | Injection Stretch Blow Molding (ISBM) | ISBM (high stretch ratio) | Extrusion Blow Molding (EBM) or ISBM (wide-mouth) | Selection driven by volume, tooling, and required clarity/mechanical properties |
| Typical Dimensional Tolerance | ±0.5–1.0 mm | ±0.5–1.0 mm | ±0.8–1.5 mm | Critical dims (neck, height) often held tighter for automated filling |
| Mold Cavity Options | Common: 4, 8, 12, 16, 24 cavities (high-cavities up to 48 available) | Higher cavities reduce per-unit cycle cost but increase tooling complexity | ||
| Typical Lead Time (samples & series) | Sample preform & sample bottles: 2–4 weeks; Production runs (new tool): 6–10 weeks | Lead times vary with tooling complexity and seasonal demand | ||
| Common Applications | Bottled water, ready-to-drink beverages, nutritional shots, small cosmetics | Compatibility with product (acidity, oils) should be verified | ||
| Sterilization & Filling Notes | Suitable for hot-fill only with validated design; cold-fill preferred; compatible with common rinse/sterile lines | Steam or chemical sterilization may affect clarity and mechanical properties — validate process | ||
| Quality / Performance Standards | Conforms to common food-contact polymer requirements; dimensional & pressure testing per buyer specifications | Testing references: ASTM D3985 (OTR), ASTM F1249 (MVTR); supplier quality plans typically include IQ/OQ/PQ | ||
| Notes & Design Considerations | Reinforced base and controlled wall distribution improve vacuum/pressure performance; label and shrink-sleeve compatibility verified during development | Light-weighting reduces material but can affect barrier and mechanical strength | ||
