The utility model provides a double sheet PE membrane moisture-proof breathable bag, enhance the permeability of the whole bag, to ensure the quality of filling process and coherence; at the same time, filling material stacking, can effectively prevent the entry of external moist air, so as to protect the bag material, including valve bag body, wherein the valve pocket the bag body is provided with an outer wall, the inner wall and the interlayer, the inner and outer walls are the kraft paper, the middle layer is a PE film, which is characterized by comprising a plurality of interlayer PE film, the PE film to overlap the edges of. The PE membrane is connected by overlapping ways, which improves the overall air permeability of the bag, ensures the quality and consistency of the material filling process, and reduces the burst bag problem caused by air permeability. The connection between PE films is simple and reduces the processing cost. After filling and stacking of materials, the PE film overlaps each other tightly and is tightly pressed together to avoid the entry of damp air outside, thus protecting the material from moisture in the bag.
【技术实现步骤摘要】
双片PE膜防潮透气袋
本技术涉及阀口袋
,具体涉及双片PE膜防潮透气袋。
技术介绍
阀口袋,俗称糊底袋,为目前国际流行包装袋,从顶部或底部阀口进料,采用专门灌装设备,灌装物料后装成方体,堆包整齐,美观,属于环保袋。目前,要求阀口袋同时具有防潮和透气的性质,大部分为砂浆用纸袋,例如瓷砖胶等,在灌装过程中因物料含有气体,袋子必须具有透气性,一边装一边排气,才能灌装到标准重量。在储存和运输的过程中,必须具有高度的防潮性,才能保证袋子中的物料不会结块,避免影响客户使用,就目前的技术来说具有一定的瓶颈。
技术实现思路
针对现有技术的不足,本技术提供一种双片PE膜防潮透气袋,提升了袋子整体的透气度,保证物料灌装过程的质量和连贯;同时,物料灌装码垛后,能有效避免外部潮湿空气的进入,从而保护袋中物料。一种双片PE膜防潮透气型阀口袋,包括阀口袋袋体,所述阀口袋袋体设置有外壁、内壁和中间夹层,所述外壁和内壁均为牛皮纸,所述中间夹层为PE膜,其特征在于:所述中间夹层包括若干片PE膜,所述PE膜的边缘相互重叠。为更好实现本技术,可进一步为:所述中间夹层包括两片所述PE膜,当在所述阀口袋袋体内填料后,所述阀口袋袋体呈方形,所述两片PE膜的重叠部分靠近所述阀口袋袋体侧面的中分线处。本技术的有益效果:PE膜之间采用重叠的方式连接,提升了袋子整体的透气度,保证物料灌装过程的质量和连贯,同时降低了因透气性而导致的爆袋问题。PE膜之间连接方式简单,降低加工成本。物料灌装码垛后,PE膜相互重叠后被紧紧的压在一起,避免外部潮湿空气的进入,从而保护袋中物料受潮。附图说明图1出示了本技术的剖视结构 ...
