Eles s\u00e3o adequados para muitos p\u00f3s e misturas secas, mas a melhor escolha depende do produto, m\u00e1quina de enchimento, peso alvo, condi\u00e7\u00f5es de armazenamento e fechamento necess\u00e1rio. Estruturas de papel, PP tecido e comp\u00f3sitas resolvem problemas diferentes. Uma v\u00e1lvula autovedante pode limitar a fuga do produto, mas n\u00e3o \u00e9 automaticamente herm\u00e9tica.
