Before production, confirm the backing and adhesive configuration, vector artwork, colour reference, repeat length, print direction, roll dimensions, core and actual carton-sealing conditions.
Report 8621.SHJ6.2608.3623.1 describes a mixed test of printed kraft paper tape and printed BOPP tape. The combined result for four heavy metals is N.D. against a 100 mg/kg limit.
The report states that the mixed-test result can differ from any single material result. A different backing, ink, adhesive or order must be checked again; it cannot support a claim that every printed tape has passed.
