Packing Standards

RSS grades are packed in 50 or 111.1 kg bales, ISNR (Block rubber) in 25 or 50 kg bales, and Centrifuged Latex (Cenex) in 194 kg barrels or flexi tanks, Or as agreed to between purchaser and supplier.

Packing standards of RSS grades - The sheets after grading are marked on the bales and marketed.  The following may also be noted while packing RSS grades.

RSS 1X/1 -  Each bale must be packed free on mould but very slight traces of dry mould on wrappers or bale surfaces adjacent to wrapper found at time of delivery will not be objected to provided there is no penetration of mould inside the bale. 

RSS 2/3 – Slight resinous matter (rust) and slight amounts of dry mould on wrappers, bale surfaces and interior sheets, found at time of delivery will not be objected to.  Should rust or dry mould in an appreciable extent appear on more than 5% (RSS 2)/10% (RSS 3) of the bales sampled, it shall constitute grounds for objection.            

RSS 4/5   - Slight resinous matter (rust and slight amounts of dry mould on wrappers, bale surfaces and interior sheets, found at time of delivery will not be objected to.  Should rust or dry mould in appreciable extent appear on more than 20% (RSS 4)/ 30% (RSS 5) of the bales sampled, it shall constitute grounds for objection. 

Packing material specifications for RSS - RSS 1x, 1, 2, 3, 4, 5 in LDP cover and for 3,4,5 may be wrapped with sheet rubber of equal or higher quality and painted with one coat of official bale coating solution as specified in IS 15361: 2003.

Packing Standards of ISNR (Block Rubber) - The material shall be wrapped in low density polythene sheets and shall be further wrapped as agreed to between the purchaser and the supplier.  The block rubber shall be further packed in pallets or crates, if required, as agreed between the purchaser and the supplier. Material of pallet/crate is wood, steel or any other material as agreed to between the purchaser and the supplier. Net mass of rubber is 1MT/1.2MT/1.26MT or as agreed to between the purchaser and the supplier. Polythene sheets which are easily dispersible in rubber and as agreed to between the purchaser and the supplier having thickness 0.030 to 0.038 mm, relative density 0.92 and melting point 109 C max are generally found suitable for wrapping raw rubber blocks. 
           
Packing Standards of Centrifuged Latex (Cenex) - For latex packing, standard size 194 kg barrels or flexi tanks or other packing material as per the agreement between purchaser and seller can be used.  Under the present procedure, each barrel of centrifuged latex may be marked with its gross weight, tare weight and drc.  MS barrels with inside paint coated with ammonia resistant bitumen paint are used for cenex filling.
