Description

可预装食品的微波炉蒸煮袋
技术领域
本发明涉及食品包装技术领域， 具体是一种可预装食品的微波炉蒸煮袋。 背景技术
塑料拉链因其质量轻、 柔顺性好、 价格低廉， 可反复使用等特点而被广泛 应用于包装领域。 虽然小巧并不起眼， 但是却紧随世界包装业的脉搏而快速发 展。 目前市场广泛应用的拉链是由一个公条和一个母槽分开的两部分组成， 公 条和母槽的边缘材质与结构基本相同，在热封时将公条和母槽同时烫压到袋子 开口的两侧， 从而达到可重复开闭袋子， 保持袋子内容物新鲜度， 安全性， 延 长内容物的保质期等优良效果。但是采用这种普通微波炉蒸煮袋子存在如下缺 点： 因排气孔是在袋子制作好后添加的， 所以袋子本体也会被打上孔， 这样预 装食品就很容易泄露到外面， 使消费者操作时麻烦， 食品也不能很好的保存。 发明内容
为了克服上述缺陷， 本发明提供了一种可预装食品的微波炉蒸煮袋， 排气 孔外层设有撕裂条或者单层薄膜材料， 在填充物料过程中， 物料不会从排气孔 渗漏。
本发明的技术方案是这样实现的： 技术方案一： 可预装食品的微波炉蒸煮 袋， 袋体内相对位置设有两排相互咬合的公条和母槽， 公条和母槽分别通过两 片薄膜连接在袋体上，袋体一侧的公条之间或者母槽之间或者公条和母槽之间 的薄膜上开有至少一个排气孔， 其上方的袋体上叠加一条撕裂条， 使撕裂条撕 开后能漏出内部排气孔。
所述排气孔上方的的拉链的打开强度为 80N/50mm，排气孔下方的的拉链的 打开强度为 30N/50mm。撕开撕裂条， 把食品放入微波炉内， 启用微波炉， 由于 热气压作用， 下排的拉链被蒸汽冲开， 排气孔处排出， 上排的拉链仍然能够保 持闭合状态。 加热完成后取出蒸煮袋打开上排的拉链， 即可食用。
所述撕裂条采用低温热封材质， 能很好的与袋体热封， 能很容易的撕开袋 体。 撕裂条一端进行热封加固处理， 当撕开撕裂条后， 末端仍然能够牢固的留 在袋体上， 这样人们就不会随手将撕下来的撕裂条丢弃， 既方便了使用者又不 会污染环境。
公条和母槽分别通过两片薄膜热封或者胶粘或者超声波粘合在袋体上。 所述拉链的上部袋体设有激光线， 激光线的末端开拉裂口， 从拉裂口处沿 激光线撕开， 可以取出内容物。
技术方案二： 可预装食品的微波炉蒸煮袋， 袋体内相对位置设有两排相互 咬合的公条和母槽， 公条和母槽分别通过两片薄膜连接在袋体上， 袋体一侧的 公条之间或者母槽之间或者公条和母槽之间的薄膜上开有至少一个排气孔，且 其上方的袋体上、 排气孔的两侧位置开有两条激光线， 激光线中间部分的袋体 可沿激光线撕开漏出内部排气孔。
所述排气孔上方的的拉链的打开强度为 80N/50mm，排气孔下方的的拉链的 打开强度为 30N/50mm。公条和母槽分别通过两片薄膜热封或者胶粘或者超声波 粘合在袋体上。 所述拉链的上部袋体设有激光线， 激光线的末端开拉裂口， 从 拉裂口处沿激光线撕开， 可以方便的取出内容物。
本发明的有益效果为： 排气孔的上表面附有撕裂条或者塑料薄膜， 预先装填 内容物时， 不会泄露在外面， 又避免了袋子在移动中或长期放置时， 从孔的位 置渗入杂质或空气细菌等， 延长食品的保质时间。撕裂条末端进行了加固热封 处理， 使其更好的固定在袋体上， 当撕开时末端仍然能够牢固的留在袋体上， 这样人们就不会随手将撕下来的撕裂条丢弃， 既方便了使用者又不会污染环 境。
