Manufacturing Technology of Foaming Buffer Packaging Material Prepared from Cannabis sativa Core Fiber

The foaming buffer packaging material was experimented to be made of the Cannabis sativa stem core fiber. The influence of the proportion of four major raw material components i.e., the amount of C. sativa stem core fiber, glue dosage, dosage of foaming agent and the additive dosage applied, upon the properties of foaming material was studied, and the properties of the foaming material were comprehensively evaluated with appearance, bulk density and shape recovery rate indexes. The results showed that the optimized raw material proportion for the processing was 300% of fiber, 200% of glue, 15% of foaming agent and 100% of additive. The foaming buffer packaging material manufactured by the optimized processing technology was assessed that the appearance was scored as 9 points, the bulk density was 0151 g/cm3 and the shape recovery rate was 322%, indicating that the foaming material could be used as buffer packaging material.
