Easy-open breathable sealing gasket

Abstract

This invention provides an easy-open, breathable sealing gasket, comprising a functional layer, a strong adhesive layer, a wireless information integration sheet, and an adhesive sealing layer. The functional layer includes a surface film and a connecting film. The adhesive sealing layer is located below the functional layer, and the strong adhesive layer and the wireless information integration sheet are located between the surface film and the adhesive sealing layer, respectively. The upper surface of the easy-open, breathable sealing gasket includes a lifting portion, a lifting neck, and a cutout area formed by a perforated cutting line. The cutout area is located around the lifting portion and is connected to both sides of the lifting neck. The thickness of the easy-open, breathable sealing gasket corresponding to the cutout area is less than the maximum thickness of the easy-open, breathable sealing gasket. The functional layer of the easy-open, breathable sealing gasket has a tear line with at least one tearing point. One end of the tear line is connected to the lifting portion, and the other end of the tear line is connected to or separated from the outermost ring of the easy-open, breathable sealing gasket by a tearing distance. The easy-open, breathable sealing gasket also includes a release layer, through holes, and a breathable layer. The release layer is located on the lower surface of the connecting film corresponding to the lifting part, or on the upper or lower surface of the wireless information integration sheet corresponding to the lifting part, lifting neck, and hollow area. The through holes penetrate the functional layer, sealing layer, strong adhesive layer, and wireless information integration sheet in a manner that avoids the placement area of ​​the release layer. The breathable layer is located below the through holes and includes a breathable membrane.
