  3. 3

Why source from us

Why Choose Ruihua

No Optical Brighteners

Food-grade PP/PE with no fluorescent agents. Many factories fail food tests on this — our color masterbatch passes without them.

Class-300,000 Cleanroom

Double-door, food-grade dust-free workshop with no cartons inside — the food-contact point global brands check.

Corrosion-Resistant Formulas

Self-developed formulas hold up to corrosive detergents and acids, staying leak-proof where others fail.

360° AI Inspection

Multi-camera AI checks every spout top-to-bottom and auto-rejects black spots and dust, with daily batch re-inspection.

In-House Test Equipment

Self-built high/low-temperature, pressure, airtightness and torque rigs guarantee sealing — rivals come to buy them.

Own Mold Factory & CNC

China’s earliest spout-cap mold maker with its own mold factory and strong CNC — full OEM / ODM.

130+ injection machines with high automation, backed by an ample raw-material reserve to secure your lead time.
