Beschreibung
Zusammenfassung:	A paperboard polymer coated carton having impregnated raw edge seams is provided. The raw edge (10) of the side seam is sealed by applying a sealant (40) directly to the paperboard raw edge (10), with the sealant (40) achieving sufficient penetration into the raw edge (10) to maintain the integrity of the sealant (40) during end use. The sealant (40) can be solvent borne, water borne, or hot melt. The sealant (40) is applied to the side seam raw edge (10) prior to the side seam operation, and the method of applying the sealant (40) is selected so that a continuous film of the sealant (40) can be applied to the side seam raw edge. The sealant (40) is one of wax, wax blend, saran emulsion, EVOH solution, polyvinyl alcohol solution, liquid adhesive, and hot melt adhesive. L'invention concerne un emballage en carton revêtu de polymère, dont les joints des bords vifs sont imprégnés. Le bord vif (10) du joint latéral est étanchéifié par application directe d'un agent d'étanchéité (40) au bord vif en carton (10), ledit agent (40) pénétrant suffisamment dans le bord vif (10) pour conserver son efficacité lorsqu'on utilise l'emballage. Cet agent d'étanchéité (40) peut être aqueux, thermofusible ou à base de solvant. On l'applique sur le bord vif (10) du joint latéral avant la sollicitation dudit joint et on sélectionne son procédé d'application de manière à en déposer une couche mince continue sur le bord vif du joint latéral. Cet agent d'étanchéité (40) peut se présenter sous l'une des formes suivantes: cire, mélange de cires, émulsion de chlorure de polyvinylidène, solution d'EVOH, solution d'alcool de polyvinyle, adhésif liquide ou adhésif thermofusible.
