Mid-2026 Bag Buyers Lock Kraft GSM with Handle Load Tests

Mid-2026 paper-bag RFQs on PackTrades show buyers refusing to approve kraft bag artwork until GSM, grade family, and handle-load test methods sit on the same specification sheet.

Brand teams say many field failures start when a bag was quoted on a nominal GSM, while handle rope, patch, and bottom construction were left to converter defaults after print plates were ordered.

Kraft converters and bag plants report more requests for retained paper lot samples, burst or tensile data with methods, and carry-test photos from production-process bags—not hand-made prototypes.

The documentation push is strongest ahead of seasonal retail peaks, when humidity and heavier gift fills expose weak handle roots that looked acceptable in dry showroom checks.

Buyers are also tying recyclable claim language to the frozen kraft grade so fiber substitutions cannot silently invalidate on-pack icons.

Why buyers care: a bag can match brand print and still tear at the handles if paper grade and load tests were never frozen with the handle construction.

Buyer takeaways

Put kraft GSM/grade, handle/patch construction, and carry-test method on every shopping-bag RFQ.

Approve production-process samples before releasing mass print.

Ban silent kraft grade substitutions without a re-tested handle-load record.
