Plastic Bottle Caps

As critical components in the packaging industry, plastic bottle caps integrate multiple functionalities through precision engineering and material innovation, providing reliable sealing solutions for global beverage, food, and daily chemical sectors.

Utilizing high - performance polymer systems:

• Food - grade polypropylene (PP) and polyethylene (PE) substrates
• Engineering plastic composites (e.g., PA/PP blends)
• Elastomeric sealing materials (TPE, silicone)
• Bio - based polymers (e.g., PLA, PHA)

• Precision injection molding (128+ cavity high - capacity molds)
• Multi - layer co - injection technology (oxygen barrier integration)
• Automated vision inspection systems (0.1mm accuracy)
• Online torque monitoring and adjustment

• Dual - seal mechanisms (primary and secondary sealing barriers)
• Child - resistant and senior - friendly designs
• Anti - counterfeiting structural elements
• Venting systems for hot - fill applications

• QR code integration platforms
• Dosage - controlled dispensing mechanisms
• Resealable flip - top configurations
• Smart cap with freshness indication

• FDA, EFSA, and LFGB food contact compliance
• ISO 9001 & 14001 certified production
• UL environmental claim validation
• REACH and RoHS chemical compliance

• Lightweight designs (up to 25% material reduction)
• Monomaterial structures for enhanced recyclability
• Ocean - bound plastic utilization programs
• Closed - loop recycling initiatives

• Carbonated beverage caps (pressure - resistant designs)
• Pharmaceutical caps (tamper - evident features)
• Edible oil caps (leak - proof seals)
• Cosmetic caps (dosing and dispensing systems)

• Statistical process control (SPC) monitoring
• 100% dimensional verification
• Accelerated shelf - life testing
• Microbial contamination prevention
