Import Delicate Paper Angle Board — Buy in Bulk from Supplier in China

Delicate Paper Angle Boards from Qingdao Rongli Packaging Co., Ltd. are rigid, L-shaped sheets made from layered kraft paper, designed to reinforce the corners of boxes containing fragile items. These boards are typically 25 mm to 50 mm in leg width and 1.8 mm to 3.2 mm thick, with lengths cut to match carton edges. The material is uncoated and contains no plastic films or laminates.

The paper layers are bonded with starch-based adhesive, a common industry method for achieving rigidity without synthetic resins. The basis weight ranges from 140 g/m² to 200 g/m² per ply, with two to three plies laminated together for durability. This construction mirrors standard practices in furniture and glass packaging, where controlled stiffness is critical to prevent edge collapse.

These angle boards are primarily purchased by manufacturers of high-value electronics, mirrors, and ceramic products who require corner reinforcement without added bulk. Buyers order in bulk quantities, often in pre-cut lengths matching their box dimensions. Packaging is in flat bundles of 100 to 500 pieces, secured with paper straps. Trade terms such as FOB Qingdao are standard, and lead times depend on customization complexity.

Qingdao Rongli Packaging Co., Ltd. is based in Jiaozhou, Qingdao, Shandong Province, and operates as an exporter of paper-based protective packaging. The company is registered as an imported supplier with harbor-level trust verification, indicating compliance with export documentation standards.
