I'm thinking of reducing adhesive consumption in box assembly which has to hold ~7 kg. The assembly process consists of product insertion, glue application on box ends and tapping along the gap (nothing extraordinary here). My question is: Why does a box even need adhesive if it gets tapped externally which I believe to withstand the weight? There're two narrow strips of glue on both ends of the box. Initial idea is to reduce the size of those strips but I don't see the point in using adhesive at all when it has tape applied instantly. I'd like to do some calculations regarding the issue. I think that shear force plays a key role in this case. How should I carry my theoretical calculations?
