How to remove vertical lines when making a cylinder

I am pulling my hair out. I have looked up every way around this and searched for plugins. I am currently using ketchup to make packaging mockups, I then export as .obj and bring into adobe substance suite and then add textures and colors, labels, etc. But not matter what I do in sketch up, soothing, adding more segments, etc, I get lines like in the photo on my packages and then the label will not apply correctly. Is this simply a sketch up thing and I nee d to use blender, or am I going about this all wrong? any input or help is appreciated. I have to rotate the label around the bottle to get it in the exact right position so the label stays in-tact, bit then pieces of it always look fragmented. Thank you so much!

What photo?
