Can't tell exactly how many nubbins there are on the base there, but if I guess 8, then we can set the segments on our initial geo to a multiple of that number, so here 16. I started with a disc, added a single loop cut where I wanted the nubs to stop, and then selected pairs of segments to extrude (no caps) or ctrl-drag an arbitrary amount to get the bumps... We can't do all them in one go if they are next to each other, so I did them 4 at a time. And then it's over to SDS to do the rest of the work for you... I quadded the centre to avoid a nasty SDS pinch there (close poly hole / patch mode). Without seeing the bottom view of the bottle, and without any similar ones lying about at home for refs, I don't really know how the bumps fade out towards the centre, but we can easily adjust that by moving the inner circle of extruded points, or we can add one more loop cut half way between edge and centre to better define that transition. You don't want to add more than 1 loop though, as then shapes will start to become too defined under SDS. The little grip bits in the cap are such relatively tiny details, nobody is going to notice if you do it in texturing, but TBH it is quicker still to just model them separately and slightly intersect them with the main model, and we certainly don't want the rest of the mesh at the sort of resolutions that the grip section would require if it were part of it ! So if you want to do that just start with a tall cube in a radial cloner, add enough Y segments to it so they SDS with the correct amount of roundness, and then set the radius in the cloner and adjust the amount and size until it looks right. It's hard to see from the pic, but it looks to me like the plastic wrap stops before the ridged bit, so we shouldn't need to worry about that ? But no matter if we do. To get the plastic wrap layer we can directly split the wrap polys from the base mesh, and then just manually adjust a few loops so it gets round the bumps OK and add parametric thickness with Thicken generator or manually via a tiny 'caps on' extrude.
