Valve Top Paper Sacks

Polesy offers Valve Top (VT) Paper Sacks with pasted rectangular bases, referred to as Block Bottoms (BB), to satisfy a wide variety of requirements in retail packaging and industrial products. 

Paper Sack design depends on the product to be packed (powder, granules, pellets, semi-viscous) and the degree of protection required to safeguard its integrity and quality, incorporating an array of compositions such as selective papers, films, foils, coatings, laminations and surfaces as suitable encapsulating barriers.
