摘要： A flexible package includes a closure arrangement having first and second closure members. Each of the first and second closure members has a pull tab extending from a respective flange. The pull tabs are constructed and arranged to selectively disengage the first and second closure members and provide access to an interior of the flexible package. Each of the pull tabs is movable between a resting position, where the tab is lying against its respective flange, and a working position, where the tab is spaced from its respective flange. Methods for constructing and using a flexible package are provided herein.

摘要： A package header arrangement includes a header with first and second opposing films, a tear bead and a support member. The support member is attached to the first film below the tear bead. The tear bead is disposed between the first and second films. When heat and pressure are applied to the first and second films in proximity to the tear bead, the tear bead scores the first and second films creating a breakable tear bead line. When heat and pressure are applied, the tear bead pushes aside the inner layer of the first and second films, weakening the film along the breakable tear bead line without harming the hermetic seal provided by the films. The breakable tear bead line tears easily because it does not have the tough, flexible inner layer of the films to aid in tear resistance. The breakable tear bead line also provides an even tear along a straight line. The support member provides support while tearing along the breakable tear bead line.

摘要翻译： 包装头部装置包括具有第一和第二相对膜的集管，撕裂珠和支撑构件。 支撑构件附接到泪珠下方的第一膜。 撕裂珠设置在第一和第二膜之间。 当热和压力施加到靠近撕裂珠的第一和第二膜时，泪珠评分第一和第二膜，产生可破裂的撕裂珠线。 当施加热和压力时，撕裂珠推动第一和第二膜的内层，使薄膜沿着可破裂的撕裂珠线线弱化，而不会损害由膜提供的气密密封。 易碎的撕裂珠线容易撕裂，因为它不具有韧性，柔性的内层，有助于抗撕裂。 可撕裂的撕裂线也沿着直线提供均匀的撕裂。 支撑构件沿着可破裂的撕裂线线撕裂提供支撑。
