Abstract

本实用新型涉及一种真空包装薄膜。解决了现有技术中平面薄膜在抽取空气时,平面薄膜极易压贴另一面接合面,使空气较难完全抽去并易使袋体遇到破坏等问题。采用表面有密布的凹凸状纹坑的有纹包装膜而制成真空包装袋(盒)。本实用新型纵横交错而相互连通的纹坑可以在使用时给空气提供通道从而保证能使空气完全抽去。

Description

真空包装有纹薄膜
本实用新型涉及一种真空包装薄膜。
食品、产品真空包装技术的使用,可减少食品的腐坏、产品的氧化。市面上很多的食品、产品的包装均采用真空包装技术处理。但由于真空包装袋使用的薄膜表面为平面型。当抽取空气时,平面薄膜极易压贴另一面接合面,其时,便较难将空气抽去,并易使袋体遭到破坏。
本实用新型的目的在于提供一种便于抽走空气、容易使包装袋形成真空状态而不破坏袋体的真空包装袋(盒)用的薄膜。
本实用新型的技术特征在于:在真空薄膜内壁表面有密布的凹凸状纹坑,纹坑纵横交错,避免了平面薄膜两接合面易贴紧的不足,抽取空气时,相互交叉而连通的纹坑能给空气提供通道,使空气容易被抽净。
所说的有纹薄膜,其表面的纹坑可以是格状、网状、颗粒状及其它凹凸状。
图1、图2为本实用新型实施例1结构示意图;
图3、图4为本实用新型实施例2的结构示意图。
下面将结合附图对本实用新型进一步详述:
图1中,1为网状有纹薄膜,2为网状纹坑所形成的突起,可由一薄膜压贴于另一薄膜而形成。
图2为图1的剖面图,1为网状有纹薄膜,2为突起,3为纵横交错,相互连通的纹坑,4为包装袋底面的平面薄膜。
图3中,5为格状有纹薄膜,6为格状纹坑形成的突起。
图4为图3的剖面图。5为格状有纹薄膜,6为突起,7为纹坑,8为包装袋底面的平面薄膜。
使用时,若包装袋薄膜完全压贴另一面的膜或盒时,纵横交错的纵坑便起作用,形成一空气通道,便于将袋(盒)内空气完全抽走而形成真空,并保证袋体不遭到破坏。

Claims (3)

1、一种真空包装有纹薄膜,其特征在于:薄膜内壁表面有密布的凹凸状纹坑。
2、如权利要求1所述的有纹薄膜,其特征在于所说的纹坑,可以为纵横交错、相互连通的格状、网状,颗粒状凹凸纹坑。
3、如权利要求1所述的有纹薄膜,其特征在于所说的凹凸状纹坑可由一薄膜压贴于另一薄膜而形成。
