• The Expert Answer: Tape failure in the Klang Valley is typically due to the adhesive type or poor surface bonding. Always use high-quality Acrylic-based OPP tapes for long-term storage and export; avoid cheaper, basic rubber-based tapes which break down in heat. For best results, ensure the carton surface is dust and oil-free before applying. Apply pressure to the tape's ends, and use at least three layers across the main seam.
