Abstract (en)
A snap-fastener bag (11) according to the present invention is composed of a quadrilateral bag body (12), a deaerating passage (13A) provided up a bottom-seal and a snap fastener (21) provided under the opening (14). The deaerating passage is provided by configurating a deaerating passage opening as a non-adhesive part between one side-seal (16B) and the bottom-seal (16C) and by configurating an adhesive part (17) from the bottom of the side-seal to near the other side-seal with the predetermined intervals from the bottom-seal in parallel to adhere between the up-and-bottom films (15). A paint film coated (19) with a sticky substance (18) having the kinematic-viscosity of 4 - 5,000x10<-><6>m<2>/s (100 DEG C) such as polybutene is formed in the deaerating passage. <IMAGE>
