Por que usar bolsas de plástico para envases de alimentos?

As bolsas de embalaxe de plástico xogan un papel importante na industria de envases de alimentos. En primeiro lugar, as bolsas de envasado de plástico teñen excelentes propiedades protectoras. They can effectively prevent food from being contaminated by the external environment.
