Plastic Bottle

1. Product Identity & Shelf Appeal
   • Clean white body = hygiene, purity, “clinic” or “salon-grade” cue.
   • Contrasting blue lid creates a fresh, water-inspired color block that stands out in a sea of neutral packs and supports sub-line differentiation (e.g., Hydrating = blue, Repair = red).
2. Primary Barrier & Preservation
   • High-density PE or PET bottle provides an inert, moisture-vapor barrier, keeping surfactants stable and fragrance from migrating.
   • Blue PP flip-top or disc-top cap gives an airtight seal, prevents leakage in transit, and reduces oxidation of actives like panthenol or botanical extracts.
3. Controlled Dispensing & Ergonomics
   • One-hand flip-top or push-button opens to a 2-3 mm orifice, delivering the ideal 3–5 g dose for medium-length hair while limiting waste.
   • Smooth cylindrical body plus slightly textured lid allow secure wet-hand grip; 250–500 mL sizes balance handling comfort with shower shelf footprint.
4. Brand Communication Surface
   • Wide, smooth label panel supports high-resolution graphics, ingredient call-outs, and QR codes for tutorials or sustainability stories.
   • White substrate enhances color vibrancy of printing and hot-stamping accents.
5. Sustainability & Logistics
   • Mono-material PE/PP combination is 100 % curb-side recyclable; both bottle and lid can be produced in up to 100 % PCR resin without color shift.
6. Regulatory & Safety Compliance
   • Meets EU, FDA, and ASEAN cosmetic packaging standards; cap can incorporate tamper-evident band or child-resistant closure if required.
