Practical Notes

This standard has been officially withdrawn by BIS. It should be used for reference purposes only and not for new manufacturing or contracts.

The specification of Weather and Boil Proof (B-WP) plywood is critical for protecting the contents from moisture, a key concern in tobacco packaging.

Exporters should refer to current international packaging standards (e.g., ISO) or specific buyer requirements for tobacco packaging.
