RD-1 Chlorinated PP Composite InkEster-soluble chlorinated PP system for dry-food lamination
Thirty years of getting the chemistry right
Dongguan Ruida Coating Co., Ltd. was established in 1997 in Gaobu Town, Dongguan, as a manufacturer of gravure and offset printing inks. Over three decades the product range has narrowed and deepened: today we focus on solvent-borne inks for flexible packaging and on the polyurethane binders that make those inks work.
In 1993 the group behind Ruida, HAOSI International, started out in packaging materials. That heritage matters to ink customers: our technical team grew up on the converting floor, not only in the lab. When a laminating job fails, we usually know which of the four variables — ink, substrate, adhesive or machine — moved.
Ruida today runs as the coatings and inks arm of the group, alongside sister plants in Jiangxi (China), Vietnam, Indonesia and Cambodia, plus a Hong Kong office. Total production area exceeds 50,000 m², the group employs more than 500 people, and 2025 sales reached RMB 300 million.

Capability, in plain terms
Formulation and colour matching
Pigment selection, let-down and colour matching against your approved standard, with a retained sample of every batch.
Dispersion and grinding
In-house bead mills and fineness-of-grind checks — the difference between an ink that prints clean and one that blocks a plate.
Lamination and retort testing
Cast-film and dry-lamination trials, plus bond-strength checks on retort structures.
Quality control
Viscosity, solid content, adhesion, solvent residue and appearance checked batch by batch.
Four production bases, one specification
Jiangxi (China), Vietnam, Indonesia, Cambodia — plus a Hong Kong office, more than 50,000 m² of production area and over 500 employees group-wide.
Certified, filed and inspected
Ink manufacturing is regulated. We keep the paperwork current — product MSDS, environmental filings and management-system certificates — so your own compliance review does not stall.
