Q.
At various places in the DGR, we see the term “Strong Outer Packaging”and also ”Strong Rigid Outer Packaging” which are used for describing packaging quality requirements. What is the difference between these two terms? The word “rigid” has a connotation of being “hard” and thus may construe to mean having a surface “hard enough” to withstand any pressure from other packages loaded alongside or “hard enough” to protect from foreign protruding objects which may come into contact. Thus the word “rigid” appears to suggest the use of wood or metal material over “non-rigid” fibreboard or plastic. However, in DGR 2.6.5 (c), “strong rigid outer packaging” is defined as wood, fibreboard or other equally strong material. On the other hand, in the same DGR, soft surface shrink-wraps are categorized as “non-rigid” overpacks. Please help us with the true definition for these two terms, “Strong Outer Packaging” and “Strong Rigid Outer Packaging”.  (31 May 18)
