Understanding Plastic Spout Cap for Flexible Pouch Packaging

Spout caps (also called pouch spout caps, plastic spout caps, or spout for pouch) transform flat flexible pouches into resealable containers with controlled pouring, perfect for liquids, viscous products, and consumer convenience. These precision injection-molded components feature leak-proof seals, tamper-evident bands, child-resistant options, and custom colors matching premium brand aesthetics.

Spout pouch cap China manufacturers like Shantou Hanle Packing Co., Ltd lead global production with 20+ years mold-making expertise, ISO9001/SGS certification, and full-service capabilities: design → mold → injection → quality control → global logistics. Their plastic spout solutions serve food/beverage (juices, sauces), detergents, pharmaceuticals, automotive chemicals, personal care, and cosmetics across Vietnam, India, Sri Lanka, and beyond.
