Vegetable and Plant Fibre
General Specifications Fibreflex "Detroiter" Plant Fibre
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.
B. Certification: Fibreflex “Detroiter” is certified to meet the below listed specifications.
