DF and V-LS: special, double overlapping film DF and V-LS from dy-pack: Rapid deaeration and optimal moisture protection. Innovations made by dy-pack: A double overlapping film layer with an air release system guarantees optimal moisture protection with fast deaeration. The fast release of air increases the filling density and so improves the filling weight accuracy achieved. Perfectly filled, stable bags make a perfect presentation on the pallet possible. The double film overlap ensures a fast air release and improves the moisture protection. Sack inner pressure EF: One overlapping film V-LS: Special overlapping film filling time DF and V-L-S: unique, double overlapping film Filling speed DF and V-L-S: unique, double overlapping film DF and V-LS: clearly better · Clearly improved moisture protection 16 · Faster filling speed 12 · Cleaner filling without dust pollution 8 · Greater weight accuracy 4 2 · Longer shelflife 1 · Optimised product density – stable palletisation without perforation with perforation A cleaner Sack More speed: Using the double overlapping film reduces the maximum pressure during filling. Comparison of EF&DF. The benefits derived is clear, faster deaeration gives shorter fill times. Your production line and the palletised sacks will be much cleaner.
