Foreword

The revised standard Japanese Industrial Standards Association JISZ1705-1979. This standard compared with JISZ1705-1979, the main differences are as follows. --- Classification material, "class" The following abolition of the "number"; --- Deleted the material requirements for water resistance and resilience; --- Increased paper-based materials for water extraction pH value and class 1 A, C, D kind of material moisture permeability requirements; --- Adds various types, species, grade material the main purpose of explanation; --- Increased requirements for moisture, mildew and other material and non-oil packaging materials. This standard replaces GB/T 12339-1990 "with protective packaging materials." This standard compared with GB/T 12339-1990, the main changes are as follows. --- Modify the protective packaging materials used in the classification, the original "class, grade, number" three levels, was changed to "class, species-level" three level; --- Improve the technical requirements with protective packaging materials, increasing class 1 A, B two water content of the test requirements, an increase of Class 1 D kind of tensile strength test requirements; increased class 1 C Species blocking resistance test requirements; --- Edit "adhesion" test name "blocking resistance"; --- Improved test methods related content, re-clear part of the test reference standard; --- Modify the heat aging resistance test, the technical requirements of Class 1 B kind of material is placed in temperature, modify the water permeability test methods for heat-sealing at The scope of application of the material used, the modified blocking resistance test species of Class 1 C temperature material is placed technical requirements; --- Revised Appendix A mesh operations technical requirements; --- Remove the inspection rules and signs, packaging, transportation, storage of content. This standard Annex A, Annex B normative appendix. This standard by the National Packaging Standardization Technical Committee (SAC/TC49) and focal points. This standard was drafted.
