Heavier-duty suspender belt is provided with in corner, four, described outer bag top.
Described netted partition is formed by connecting by horizontal stripe and vertical bar, is provided with heavier-duty point of connection at described horizontal stripe and vertical bar junction.
Described PA film is fixedly connected with inner bag blanching.
Described PA film is fixedly connected with netted partition blanching.
Described netted partition is overlapped on the corner of inner bag, and described netted partition and inner bag sidewall are 45 °.
Described inner bag and outer bag are respectively equipped with inlet point and discharging opening.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: integral structure of the present invention is simple, reasonable in design, easy to use and reliable, described inner bag is by aluminium foil, bonding coat and PET film nine layers are co-extruded, there is excellent high barrier, adopt described netted partition, ensure that overall molding effect is good, anti-expandability is excellent, large quantity space can be saved, meet transportation request, described netted partition is formed by connecting by horizontal stripe and vertical bar, heavier-duty point of connection is provided with at described horizontal stripe and vertical bar junction, Joint strenght is high, described netted partition is connected with inner bag by PA film, after using baffle plate in bag body before solving, the problem of PE plastic inner bag cannot be added again, in adopting, Over-bag is combined, good leak tightness, health is clean, adopt heavier-duty suspender belt, suspender belt is not drooped, facilitate the handling of flexible freight container, improve whole work efficiency, realistic operating needs.
