Multiwall Paper Sacks
To suit everyone’s need
The type of multiwall sack to be used for a certain application depends on a number of factors, including, the physical characteristics of the type of product to be packed, the way in which it will be transported, stored and distributed, and the way in which it will be used by the final customer, amongst other things. Each variant has its advantage of custom design barriers offering different size packaging for different net weights of product, and excellent print graphics for shelf appeal, thus making multiwall sack the most preferred flexible packaging product.
