摘要： A plastic bag comprises first and second panels each having a top, a bottom, and first and second opposing sides. The first and second panels (25, 26) are joined to each other along their respective bottoms, their respective first opposing sides, and their respective second opposing sides. The plastic bag includes a zipper (11) having a male and female track (12). The male track includes a male profile and a first fin (16), in which the first fin is affixed to the first panel in proximity to the top of said first panel. The female track (13) includes a female profile and a second fin (16), in which the second fin is affixed to the second panel in proximity to the top of said second panel. The male and female profiles having complementary cross sections. The inventive fins comprises a first resin and optionally a second resin which along with the fins seals are able to withstand greater forces and more adverse conditions. At least one of the fins comprises a first resin having a polydispersity of about 1 to about 4, a melt index of about 0.2 to about 20, and a melt flow ratio of about 12 to about 35. The second resin, if used, may either be coextruded or blended with the first resin.

摘要： A reclosable plastic bag comprises first and second opposing panels fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The bag is provided with a reclosable zipper (22) extending along a mouth formed opposite the sealed bottom (20). The zipper includes a male track with a male profile and a female track with a female profile. A slider (32) is slidably mounted to the zipper for movement between a closed position and an open position. The male and female profiles are engaged to each other while the slider is in the closed position. The male and female profiles are disengaged from each other in response to movement of the slider to the open position. To prevent tampering with the contents of the plastic bag prior to being initially opened, the slider is initially parked in the closed position at one end of the zipper, and upper edges of the male and female profiles are detachably connected to each other, except at the one end of the zipper supporting the parked slider. The slider cannot be moved from the closed position until a one-time tamper-evident feature (36, 38) is broken or, alternatively, movement of the slider from the closed position will break the tamper-evident feature.
摘要翻译：可再封闭的塑料袋包括沿着一对侧面彼此固定连接的第一和第二相对的面板以及桥接该对侧面的底部。该袋设置有沿着与密封底部（20）相对形成的口延伸的可再闭合的拉链（22）。拉链包括具有公型材的男性轨道和具有女性轮廓的女性轨道。滑动件（32）可滑动地安装到拉链上，用于在关闭位置和打开位置之间移动。当滑块处于关闭位置时，阳型和阴型彼此接合。响应于滑块移动到打开位置，阳和阴轮廓彼此脱离。为了防止在最初打开之前篡改塑料袋的内容物，滑块首先在拉链的一端停放在关闭位置，并且阳型和阴型材的上边缘彼此可拆卸地连接，除了在拉链的一端支持停放的滑块。直到一次性篡改特征（36,38）破裂为止，或者滑块从关闭位置移动将破坏防篡改特征，滑块不能从关闭位置移动。

摘要： A plastic bag comprises first and second opposing panels, a reclosable zipper, and a slider. The first and second opposing panels are fixedly connected to each other along a pair of sides and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth formed opposite the bottom. The zipper includes a first track with a first profile and a second track with a second profile. The first and second profiles are releasably engageable to each other. The slider is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles are engaged to each other while the slider is in the closed position, and the first and second profiles are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider from going past the ends of the zipper and to provide adequate end strength that resists stresses applied to the profiles during normal use of the bag, end terminations in the form of posts pass through the male and female tracks adjacent to the ends of the zipper. To retain the posts on the zipper, each of the posts includes enlarged heads at its opposing ends.

摘要： The present invention provides a plastic bag to which a zipper (24, 32) having fins (26, 34) may be attached without fusing the fins together. The bag has an excellent seal between the fins and the respective body panels (12, 14) of the plastic bag. The zipper includes a male and female track. The male track includes a male profile (24) and a first fin (26) with the first fin having an inner layer (28) and an outer layer (30). The female track includes a female profile (32) and a second fin (34) with the second fin having an inner layer (36) and an outer layer (38), in which the inner layers of the fins are formed from a higher melting point material than the outer layers of the fins. Preferably, the inner layer should have a melting point at least about 5 DEG C higher than the outer layer seal to be produced between the fins and their respective body panels without fusing the fins to each other. Some examples of higher melting point material resins comprising the inner layer include the following: high density polyethylene (HDPE), linear low density polyethylene (LLDPE), metallocene-catalyzed LLDPE, polypropylene (PP) and ethylene-propylene copolymer (E-P copolymer). Resins comprising the lower melting outer layer include the following: ethylene vinyl acetate copolymer (EVA), low density polyethylene (LDPE), very low density polyethylene (VLDPE), LLDPE and metallocene-catalyzed LLDPE.

摘要： The present invention improves performance of the side and/or fin seals (16) of plastic bags through the use of resins that have a narrow molecular weight distribution or polydispersity. The performance of the side seal and/or fin seal of a plastic bag is improved by using body panels (25, 26) which comprise a first resin, and optionally, a second resin. The first resin is preferably prepared in the presence of a single site catalyst. The first resin has a polydispersity of from about 1 to about 4, a melt index of from about 0.2 to about 20, and a melt flow ratio (I20/I2) of from about 12 to about 35. The use of such first resins results in side and fin seals which are stronger, tougher, and less likely to leak. The second resin is a polymer such as LDPE, LLDPE, or a blend thereof. In body panels comprising both a first and a second resin, the first resin may be coextruded with LDPE or LLDPE as a thin layer of the body panel or the first resin may be blended with the LDPE and/or LLDPE.
摘要翻译：本发明通过使用具有窄分子量分布或多分散性的树脂来改善塑料袋的侧面和/或翅片密封件（16）的性能。通过使用包括第一树脂和任选地第二树脂的主体面板（25,26）来改善塑料袋的侧密封和/或翅片密封的性能。第一树脂优选在单中心催化剂存在下制备。第一树脂具有约1至约4的多分散性，约0.2至约20的熔体指数和约12至约35的熔体流动比（I20 / I2）。使用这种第一树脂结果侧面和翅片密封件更坚固，更坚韧，更不可能泄漏。第二种树脂是诸如LDPE，LLDPE或它们的共混物的聚合物。在包括第一和第二树脂的主体面板中，第一树脂可以与LDPE或LLDPE共挤出作为主体板的薄层，或者第一树脂可与LDPE和/或LLDPE共混。

摘要： A plastic bag comprises first and second opposing panels, a reclosable zipper (22), and a sider (32). The first and second opposing panels (12, 14) are fixedly connected to each other along a pair of sides (16) and a bottom bridging the pair of sides. The reclosable zipper extends along a mouth (10) formed opposite the bottom. The zipper (22) includes a first track with a first profile (24) and a second track with a second profile (28). The first and second profiles are releasably engageable to each other. The slider (32) is slidably mounted to the zipper for movement between a closed position and an open position. The first and second profiles (24, 28) are engaged to each other while the slider (32) is in the closed position, and the first and second profiles (24, 28) are disengaged from each other in response to movement of the slider from the closed position to the open position. To prevent the slider (32) from going past the ends of the zipper and to provide adequate ends strength that resists stresses applied to the profiles during normal use of the bag, end stops (36) in the form of flexible segments severed from a flexible plastic strip, fairly rigid segments severed from an extruded clip profile, or softened plastic material, are applied and secured to opposite ends of the zipper.
