包装胶合板
Packing plywood is made from eucalyptus wood and eco-friendly glue, hot-pressed under high temperature and pressure into strong packaging panels.
- High load-bearing capacity: even a 6 mm board can support up to 1 ton.
- Lightweight: made entirely from eucalyptus, it is lighter than many alternative materials and helps reduce overall packaging weight.
- Bending and compression resistant: high flexural strength ensures the board remains undeformed even under heavy cargo pressure.
Log Cutting & Debarking
First, selected pine logs are cut to suitable lengths and debarked.
Flaking into Thin Strands
The debarked logs are then flaked into thin strands with a length of 70–120 mm, a width of 15–25 mm and a thickness of 0.6–0.8 mm.
Storage, Drying & Moisture Control
The strands are conveyed to the storage bin, and after discharging from the bin they are dried. Once dried, the moisture content of the pine strands is controlled to around 2%.
Screening, Cleaning & Resin Blending
The dried strands are then screened and classified to remove impurities, ensuring that the raw material for the OSB contains no stones, plastics, splinters or other foreign matter. After screening, the strands are sent to the resin-blending section, where adhesive is evenly sprayed onto them before they are conveyed to the forming line.
Oriented Mat Forming
In the oriented forming section, the surface strands are oriented parallel to the length of the mat, while the core strands are oriented perpendicular to the length of the mat. This cross-oriented structure helps to increase the internal bond strength and dimensional stability of the OSB.
Manual Surface Inspection
The formed mat is then sent to the manual inspection area, where discolored, moldy strands and other visible contaminants are removed to make the surface flatter and cleaner.
Pre-Pressing, Hot Pressing & Trimming
After inspection, the mat is pre-pressed and cut to size, and the whole panel is formed and fed into the hot press for high-temperature, high-pressure pressing. After hot pressing, the board is cooled and trimmed to produce a finished OSB panel.
Final Quality Inspection
The trimmed panels are then inspected by dedicated quality inspectors, who check panel dimensions, thickness, flatness and other surface parameters.
