摘要： A method and packaging system for forming a sealed vacuum package having minimal residual air remaining. At least one vacuum lance is provided in the interior of a partially-formed package to withdraw the air, the package being closed on three sides and having a fourth side open for insertion of the vacuum lance. An air restriction can be provided along the fourth side to form a closed edge that prevents ingress of air into the package interior after the evacuation of air. In one aspect, the air restriction may comprise a pair of pinch rollers that compress the package at the fourth side edge to form a pinch seal that provides a relatively airtight air chamber inside of the package prior to and during sealing of the package. In another aspect, the air restriction may comprise a partial seal formed around the lances to prevent or minimize air from reentering the package. In yet another aspect, the air restriction may comprise a compressed air seal formed by an air compression device that keeps the ends of the film pressed together.
摘要翻译： 一种用于形成密封真空包装的方法和包装系统，其中剩余空间最小。 在部分形成的包装的内部设置至少一个真空喷枪以抽出空气，该包装在三侧封闭并且具有用于插入真空喷枪的第四侧。 可以沿着第四侧设置空气限制，以形成封闭的边缘，以防止空气排空后空气进入包装内部。 在一个方面，空气限制可以包括一对夹送辊，其在第四侧边缘处压缩包装，以形成夹紧密封件，其在包装之前和期间在包装件的密封期间在包装内提供相对气密的空气室。 在另一方面，空气限制可以包括围绕喷枪形成的部分密封件，以防止或最小化从重新进入包装的空气。 在另一方面，空气限制可以包括由空气压缩装置形成的压缩空气密封件，其将膜的端部压在一起。
