SIDE gusseted valve sacks
|
This sack variant is an side gusseted sack which is sealed at the top and bottom. A valve for filling the sack is sealed into the longitudinal seam on the rear. During production, the use of adhesives is omitted entirely, with the result that aggressive and adhesive-intolerant products can also be packaged. Plastic films or laminates can be used depending on the product's requirement.
On use of an aluminium laminate in combination with a sealable, external tuck-in valve, the side gusseted sack offers absolutely impermeable packaging with top barrier properties.
