About Us
Established in 2005, Shandong Sinocoroplast Packing Co., Ltd. operates a 30,000 m² manufacturing facility in Zibo, China, providing reliable PP corrugated plastic solutions for packaging, agriculture and industrial applications. With stable material formulation, controlled production processes and export-ready packaging, we support long-term supply programs for global customers.
Core Product Categories
PP corrugated plastic sheet (often referred to as “coroplast”) is widely used worldwide as a durable and environmentally friendly packaging material.
Its hollow structure provides an excellent balance of strength and weight, while being waterproof, recyclable and reusable — making it a reliable alternative to cardboard, wood, metal and rigid plastic sheets in packaging, agriculture and industrial applications.
Manufacturing Capacity
We operate 11 advanced PP corrugated sheet production lines, capable of producing sheets up to 3,000 mm in width, with thicknesses ranging from 2 to 15 mm and weights from 250 to 4,000 g/m².
For downstream processing, we are equipped with 5 fully automatic flatbed die-cutting machines, supporting precision die-cutting up to 1,850 mm — enabling stable output for both standard and custom packaging solutions. This capacity allows us to support repeat orders and long-term supply programs with consistent quality.
