8Oz Empty Plastic Squeeze Bottles With Disc Top Flip Cap China 29Mm Flip Top Cap Manufacturer

• Capacity: 8Oz (236.59ml) – Standard volume for daily-use products, balancing portability and content quantity.

• Material: Food-grade & BPA-free PET (Polyethylene Terephthalate) – Flexible for easy squeezing, non-toxic, odorless, and resistant to oil, acid, and low-temperature (≤60℃/140℉) environments. Optional HDPE material for enhanced impact resistance (customizable per request).

• Dimensions:

• • Bottle Height (without cap): 150mm ±2mm

• • Bottle Diameter (body): 58mm ±1mm

• • Neck Finish: 29mm (matches 29mm disc top flip cap, compatible with industry-standard 29mm closures)

• Squeeze Performance: Medium flexibility – Easy to dispense thick liquids (e.g., lotion, shampoo) or thin fluids (e.g., hand sanitizer, cooking oil) without deformation after repeated use.

• Weight: 22g ±1g (bottle only) – Lightweight for transportation cost savings, yet sturdy enough to avoid breakage.

• Color: Transparent (standard) – Allows end-users to see content level; customizable to opaque/colored (e.g., white, black, pink) via food-grade masterbatch.

• Material: High-density PP (Polypropylene) – Heat-resistant (≤100℃/212℉), corrosion-resistant, and durable for long-term use.

• Structure: Disc top flip design – One-handed operation (flip to open, press to close), with a built-in silicone gasket for leak-proof sealing (tested to hold 0.5m drop without leakage).

• Size: 29mm (neck fit) × 18mm (cap height) – Perfectly matches the 8Oz bottle’s neck, no loose or tight fitting issues.

• Customization: Support logo embossing/debossing (e.g., brand name, product logo) and color matching to align with bottle design.

1. Raw Material Selection & Inspection: Source food-grade PET/PP granules from certified suppliers (SGS-approved). Test raw materials for BPA content, flexibility, and chemical resistance before production.

2. Bottle Injection Molding: Melt PET granules at 260–280℃, inject into bottle molds (customized for 8Oz size) to form bottle preforms. Cool to room temperature (25℃) for shape stabilization.

3. Blow Molding: Heat preforms to 90–110℃, use high-pressure air (0.8–1.2MPa) to blow preforms into 8Oz bottle shapes. Precision control of air pressure and temperature ensures uniform wall thickness (0.8–1.0mm).

4. Cap Injection Molding: Melt PP granules at 180–200℃, inject into 29mm flip cap molds. Integrate silicone gaskets into caps during molding to ensure sealing performance.

5. Assembly: Manually inspect bottles (for scratches, deformation) and caps (for gasket tightness) before assembling. Use automated machines to screw caps onto bottles, ensuring consistent torque (3–5N·m) to avoid leakage.

6. Cleaning & Disinfection: Pass assembled bottles through an ultrasonic cleaning machine (38kHz frequency) to remove dust/oil, then sterilize via UV light (254nm wavelength) for 30 seconds—meeting food/pharmaceutical hygiene standards.

7. Final Inspection & Packaging: Randomly sample 5% of each batch for leakage tests (immerse in water, apply 0.3MPa pressure), squeeze durability tests (1000 cycles), and dimension checks. Qualified products are packed in corrugated boxes (500 bottles/box) with moisture-proof liners.

• Ergonomic Squeeze Design: The bottle’s cylindrical body with a slightly tapered neck fits comfortably in hands, reducing fatigue during repeated squeezing (ideal for daily-use products).

• Leak-Proof Flip Cap: The 29mm cap’s silicone gasket and tight flip closure prevent leakage during transportation or storage—solving common pain points for travel-sized or bulk-packed products.

• Transparent Visibility: Standard transparent bottles let consumers check content remaining, increasing user convenience (critical for cosmetics and household cleaners).

• Brand Customization: Support full-body screen printing (up to 4 colors) for bottle labels (e.g., product ingredients, usage instructions) and logo engraving on flip caps—helping your brand stand out on shelves.

• Eco-Friendly Option: Offer recyclable PET/PP materials (marked with recycling symbols #1 for PET, #5 for PP) to align with global sustainability trends, appealing to eco-conscious clients.

• Pre-Production QC: Raw material testing (BPA-free, chemical resistance) and mold calibration (check dimension accuracy of bottle/cap molds monthly).

• In-Production QC: Assign 1 QC inspector per production line to monitor molding temperature, blow pressure, and assembly torque. Reject any products with scratches, uneven walls, or loose caps.

• Post-Production QC: Conduct 5 key tests on finished batches:

• • Leakage Test: Immerse bottles in water, apply pressure to check for bubbles (pass rate ≥99.9%).

• • Squeeze Durability Test: Repeat squeezing 1000 times; no bottle deformation or cap breakage allowed.

• • Temperature Resistance Test: Expose bottles to 60℃ for 24 hours; no material softening or color change.

• • Chemical Resistance Test: Fill bottles with 50% ethanol (simulate sanitizer) for 7 days; no material corrosion.

• • Dimension Test: Use calipers to check bottle/cap sizes (tolerance ≤±2mm).

• Certifications: All products pass SGS, FDA, and LFGB (EU food contact) certifications—valid for sales in EU, USA, Canada, and other strict-regulatory markets.

• Free Samples: Offer 5–10 free 8Oz squeeze bottle samples (with 29mm flip caps) for quality testing and design confirmation—delivered within 3–5 days via DHL/FedEx.

• Bulk Order Support:

• • Minimum Order Quantity (MOQ): 10,000 pieces (lower MOQ available for repeat clients).

• • Lead Time: 7–12 days for standard orders; 15–20 days for customized orders (color/printing).

• • Logistics: Partner with DHL, UPS, and sea freight carriers to deliver to 60+ countries. Provide door-to-door service and trackable shipping numbers.

• Defect Resolution: Offer a 12-month quality guarantee. If any bottles/caps have leakage, material defects, or dimension issues, we provide free replacements or full refunds within 48 hours of complaint submission.

• Technical Support: Our engineering team provides 24/7 consultation on material selection, design optimization, and packaging solutions (e.g., adjusting squeeze flexibility for thick liquids).

• Documentation Support: Supply all necessary documents for import: commercial invoice, packing list, FDA/SGS certificates, and customs declaration forms—simplifying your customs clearance process.
