To improved sealing of member insert and its dispensing properties, inner and outer holding planes pass at angle to above- indicated parallel planes. To manufacture package with hole for sealing member, first hole in package material is formed by piercing. Then at least one layer of coating is applied to each side of material. Then second hole is made in coating layers of size smaller than that of first hole. EFFECT: enhanced sealing of member in package and reduced damage of material. 18 cl, 14 dwg
