（Kindly explain about the Packing Instruction for Polymeric Beads.）
Q.
In the Additional Packing Requirements under PI 957, it says: “for other than metal packagings a sealed plastic liner must be used”. What does this exactly mean? For instance, if we place the material into a strong plastic bag and tie the closure and place it inside a 4G package, would that satisfy this requirement? (31 May 13)
A.
The “sealed plastic liner” mentioned in PI 957 must be water tight or air tight. A simple tying the closure of the plastic bag is insufficient.
Please also refer to the definition of LINER in Appendix A where it defines a LINER as “a separate tube or bag inserted into a packaging but not forming an integral part of it, including the closure of its openings.
You need to place the material into a sturdy plastic bag, seal its closure air tight, and place it inside a 4G package.
