Know the legal recyclability grade before the artwork goes to print.
Korea grades every package Best, Good, Fair or Difficult. A Difficult pack must say so on its face and pays more in producer fees. Describe your pack and see the grade, the exact clause behind it, and the cheapest fix.
Grade a whole product range in one pass.
Upload one CSV row per SKU. Gradeproof grades every row, adds up the tonnes of packaging that would carry a "재활용 어려움" (Difficult) mark, and ranks the single design changes that lift the most SKUs.

Use the template (column names are the field keys shown under "The rules"), or load the sample range of a fictional drinks and food maker to see the report.
Where every verdict comes from.
Gradeproof encodes Annex 1 of the Korean Packaging Recyclability Grading Standard, rule by rule. Each finding quotes the Korean clause it applies and gives an English working translation.
