A. Scope: Fibreflex “Detroiter” is an excellent grade of vegetable fibre sheet packing, efficiently saturated with a glue-glycerine impregnant rendered insoluble by means of a tanning agent (formaldehyde) to give a strong, flexible, all-proof packing with properties retained during proper storage and in use. |
| |
|
| |
