The Majority Of Complaints Received By PT Xyzwere Related To Thequality  Of  Products  Not  Meeting  The  Promised  Age,  Particularly  Regarding The Discrepancy Between Actual And Claimed Product Shelf Life  On  Wafer  Roll  Packaging.  This  Research  Employed A  Descriptive  Quantitative Approach Utilizing An 8D Methodology Integrated With Various  Quality  Management  Systems  (QMS)  Tools  To  Identify  The  Root   Cause   Of   Customer   Complaints.   Additionally,   The   Sorption   Isotherm Method Was Utilized For Theoretically Accelerated Shelf-Life Testing  Aimed  At  Designing  More  Efficient  Packaging  Solutions.  The Main  Goal  Was  To  Reduce  Complaints  By  Implementing  A  Tailored  Quality Management System. The Findings Indicated   That The Existing Plastic Types (PET12/INK/ADH/VMPET12/ADH/LLDPE 50), With A WVTR  Value  Of  0.5  G  H2O/M².  Day, Were Not Suitable For Wafer Roll Products  With  A  15-Month  Product  Life.  Conversely,  Alternative  Packaging  Materials  With  A  Permeability  Value  Of  0.0032125  G  H2O/M². Day. Mmhgand WVTR Value ≤ 0.1596 G/M²/24 Hours Wereidentified As Capable Of Achieving The Desired Product Shelf Life. This Approach  Significantly  Reduced Customer  Complaints  Related  To  Product  Shelf  Life  By  Selecting  Appropriate  Packaging  Materials  For  Wafer Roll Products. Following The Implementation Of The Task Forceproject, Complaints  Decreased    From  7  Cases  To  0 Cases  Of  Customer  Complaints Regarding Soggy Wafer Roll Products At PT XYZ Observed Within 12 Months.
