packaging of plywood, blockboards and flush doors for export
1976 Edition

IS 8001 (1976) details packaging protocols for plywood, blockboards, and flush doors intended for export to protect against transit damage. Recommended methods include using moisture-resistant coverings like polyethylene sheets or tarpaulins, applying protective edge strips, bundling panels securely with steel or plastic straps, allowing ventilation through gaps to avoid fungal growth, and marking bundles with clear handling and product information. These measures help maintain product integrity and facilitate safe handling.

The standard specifies using sawn wooden planks combined with hoop iron strips for crate assembly, typically employing seasoned hardwood for durability. Frame components, battens, and struts must conform to sizes that support loads up to 250 kg, with crate dimensions standardized as per the detailed tables and figures within IS 8001. Crates are constructed by nailing or bolting wooden frames reinforced with hoop iron to ensure secure packaging of plywood, flush doors, and similar panel products.

To guard against moisture intrusion during transport, IS 8001 mandates the use of layered wrapping: first, a waterproof barrier such as plastic sheets or waterproof paper, followed by sewing a covering of hessian cloth around the package. This combination offers effective moisture resistance along with mechanical protection and breathability, significantly reducing the risk of water damage and preserving the quality of the packaged wood products.

According to IS 8001, hoop iron used in crates must be at least 19 mm wide and 0.45 mm thick. Each crate requires between 2 to 3 hoops width-wise and 5 to 6 hoops length-wise, depending on crate size. Hoop irons are used to fasten and reinforce the wooden frames, with nails positioned at least 15 mm from edges and struts spaced no more than 50 mm apart. Each frame member end should be secured with a minimum of two nails to maintain crate strength.

When packing decorative panels as per IS 8001, the decorative faces should be positioned inward, facing each other, while commercial faces face outward. For double-sided decorative panels, additional commercial plywood panels should be placed at the top and bottom before wrapping. The crate dimensions must follow the specified inner size allowances with an additional 10 mm clearance in height. Wrapping with moisture-resistant materials like plastic sheets and final covering with hessian cloth is essential. The total packed weight must not exceed 250 kg to prevent damage during shipment.
