Why flat pouches stay popular
Every format trend comes and goes, but flat pouches persist because the economics are unbeatable: two webs, three seals, done. When your product doesn't need to stand up or pour, paying for gussets and fitments is wasted spend. The flat pouch puts that budget into better film, better print, or better margin.
