GuardP is the Export Brand of Guangzhou Zhengyuan Packaging Products Co., Ltd.
Founded in July 2009 and based in Huadu District, Guangzhou, we manufacture paper corner boards, heavy-duty corrugated boxes, honeycomb boxes, paper pallets, molded pulp inserts, honeycomb panels and paper display products — over 10 million meters of corner board and 100,000 heavy-duty boxes per year.
Our factory runs fully automatic high-speed L-profile, U-profile, flat and wrap-around corner board lines, plus board carving, slitting, precision sawing, angle-cutting, laminating and stitching equipment, and a professional drying kiln for moisture-critical orders.
Quality control is in our own lab: compression, ring-crush and bending testers, grammage scales, moisture meters and drying ovens — with checks from raw material intake through finished-goods inspection. We are ISO 9001 certified.
Our products protect machinery, home appliances, furniture, building materials, medical devices and automotive parts — and we aim to be the packaging partner you never have to think twice about.
Our promise: integrity first, strength foremost, wholehearted service.
