Embedding structure for cutting edge of multi-layer packaging material

Patent Name A Multi-layered Packaging Material Cutting Edge Embedding Structure Patent Applicant Gaozhongyi Applicant Address 273300 Shandong Gaochunyi, inventor of Linyi Melody Packing Co., Ltd., Chengnan County, Shandong Province ) No. 200420089174.1 Application date 2004.08.30 Certification date Approval Notice No. 2734661 Validation announcement date 2005.10.19 Instruction CD-ROM D0542 Main classification number B65D65/40 Classification number B65D65/40 Division Original number Priority Item Abstract A multilayer packaging The embedded structure of the sheared edge of the material relates to a multilayer packaging material for packaging liquid, in particular to an embedded structure of a bare inner layer of a multilayer packaging material. In order to overcome the defects of the multi-layer packaging material, the exposed inner layer of the cut line is exposed to the air or soaked by the liquid, the structural layer at the cut-off line is easy to separate and fall off, the packaging apparatus is damaged, and the toxic substances are contaminated. The technical proposal is that: the strip film (6) folds and embeds the embedded structure of the cut edge of the multi-layer packaging material of the exposed inner layer (8) and the outer side surfaces (4) on both sides thereof along the clipping line (3). Since the exposed inner layer (8) is embedded in the strip-shaped film (6), it overcomes the problems that the packaging equipment caused by the expansion, deformation, or adhesion of the matrix due to the nakedness caused by the liquid sterilization, liquid packaging, or other liquid treatment is easy to handle. Loss, or defect due to contamination by harmful metal ions or hazardous chemicals. Sovereignty item 1, an embedding structure for a cut edge of a multilayer packaging material, comprising a multilayer packaging material (7) and a strip film (6), characterized by a strip film (6) along a cut line (3) Fold the exposed inner layer (8) on the cut-out line (3).
