High Quality Plastic ABS Flip Top Cap – Small Plastic Bottles With Flip Top Caps

• Impact-Resistant ABS Material: Unlike ordinary plastic caps, ABS plastic withstands drops (0.8m height) and daily wear (no cracking or discoloration)—ideal for travel or kids’ products.

• One-Hand Flip Operation: 30° ergonomic hinge (3D-simulated for optimal opening) allows easy flipping with one finger (even wet hands)—no need to twist or pull, perfect for on-the-go use (e.g., applying hand sanitizer while walking).

• Airtight Silicone Seal: 3D-machined groove in the cap base secures the silicone gasket (Shore A 50 hardness)—prevents liquid seepage (even for thick products like lip gloss) and blocks air (extends shelf life by 3–6 months).

• Non-Slip Grip: Textured ABS surface on the cap top (micro-ridges) provides extra grip—avoids slipping when opening with wet hands.

• Compact & Portable: 50ml–250ml capacity fits in pockets, purse side compartments, or travel toiletry bags (no bulky overhang)—ideal for sample-sized cosmetics (lip oil, face serum) or travel essentials (mini hand sanitizer).

• Wide Mouth Option: 24mm mouth for 150ml–250ml bottles (easy to refill with thick products like lotion; no funnels needed) while maintaining compatibility with the 20/410 flip top cap.

• Stackable Base: 4cm diameter base (for 100ml model) is designed for stackability—saves space in bathroom cabinets or retail displays (critical for small businesses with limited storage).

• ABS Plastic for Caps: Source FDA-certified ABS resin from ISO 9001 suppliers (e.g., BASF, LG Chem)—test each batch for BPA, heavy metals, and impact resistance (must withstand 1kg weight drop without breaking).

• PP Plastic for Bottles: Use food-grade PP resin (meets FDA 21 CFR 177.1520)—test for heat resistance and chemical stability (no leaching when in contact with oils or alcohols).

• Silicone Gaskets: Food-grade silicone (Shore A 50)—test for elasticity (must return to shape after 10,000 compressions).

• Bottle Molding: Use precision injection molding machines (tolerance ±0.02mm) to form PP bottles—control wall thickness (1.5mm) and neck finish (20/410) for consistency. Cool bottles in 3-stage cooling tunnels (avoids warping).

• Cap Molding: Inject ABS resin into custom molds (for cap body and flip lid)—ensure hinge thickness (1mm) is uniform (prevents hinge breakage). Post-mold trim excess plastic (no sharp edges).

• Gasket Installation: Automatically insert silicone gaskets into cap grooves (thermal bonding for ABS caps—no glue, avoids contamination).

• Logo Application: Silk-screen print logos on caps/bottles (use food-safe inks); cure in UV ovens (30 minutes) for fade resistance (tested to withstand 500+ washes with soap and water).

• Flip Mechanism Calibration: Manually test each cap’s flip hinge (must open to 30° and close securely—adjust torque if needed).

• Bottle Checks:

• • Visual inspection: No bubbles, scratches, or warping.

• • Capacity test: Fill with water to verify volume (±2% accuracy).

• Cap Checks:

• • Leak test: Screw cap onto bottle, fill with water, invert for 24 hours (0% leakage allowed).

• • Durability test: Flip hinge 1,000 times (no breakage or loose hinges).

• Final Assembly Check: Pair bottles with caps, test capping/opening once more—reject any mismatched or defective units.

• Retail Packaging: Individual bottles (with caps) packed in recyclable PE bags (1 unit/bag) or cardboard blister packs (for shelf display)—print “BPA-Free” and “FDA Approved” labels.

• Bulk Packaging: 100 bottles/cap sets per recyclable cardboard box (with foam dividers to prevent scratches)—include a packing list and compliance certificate.

• Sample-Sized Products: 50ml–100ml bottles for lip gloss, face serum, or hair oil—perfect for brand giveaways or trial sizes (compact, easy to ship).

• Travel Toiletries: 150ml–250ml bottles for shampoo, body wash, or lotion—TSA-compliant (fits carry-on bags); flip top cap prevents spills in luggage.

• Condiments: 100ml–150ml bottles for salad dressing, honey, or hot sauce—small enough for picnic bags; airtight cap keeps condiments fresh.

• Edible Oils: 50ml–100ml bottles for olive oil or truffle oil (small portions for cooking; clear design shows oil color).

• Hand Sanitizer: 50ml–100ml bottles for on-the-go sanitizer—flip top cap allows one-hand use (no need to unscrew lids); ABS cap resists alcohol corrosion.

• Cleaning Products: 150ml–250ml bottles for natural cleaners (e.g., vinegar-based sprays)—child-resistant flip top option available for safety.

• Handmade Goods: Ideal for craft brands selling homemade lip balm, lotion bars, or essential oil blends—customizable logo and color help build brand recognition.

• E-Commerce: Lightweight (100ml bottle = 20g) and compact—reduces shipping costs (critical for small businesses with tight budgets).
