Buyers should confirm unwind direction from the actual machine web path: identify the leading artwork edge, print face, sealant face, and registration-mark side, then approve a marked diagram or sample roll. A supplier direction number alone is not enough because numbering systems can differ.

Buyers should choose side-gusset depth from the coffee’s actual filled volume, target pack shape, usable seal area, and packing equipment—not fill weight alone. We confirm the dimension convention with a drawing, then test the chosen size using the real coffee before bulk production.

Buyers should leave open the edge that gives their filling equipment the straightest, widest access while preserving enough clean film for the final seal. We confirm the opening, seal allowance, artwork direction, and opening features together before production.

Choose a round hole for a simple single-hook display and consider a Euro slot when the retailer uses that fixture or the pouch needs a wider hanging interface. Final selection must follow the actual hook, filled weight, header layout, and hanging test.

Buyers normally avoid a new plate fee when they reorder the exact same confirmed pattern. Changes to artwork, size, layout, colors, or print specifications may require new plates, so every revision needs supplier review before production.

The tear notch should sit below the finished top seal and above the zipper, with enough removable header for a clean grip and enough clearance to protect the reclosure. Buyers should approve its exact position on the final dieline and confirm it with filled-pouch opening tests.

Buyers should size and position a clear window only after confirming the filled product level, pouch folds, zipper, seals, artwork, and display angle. We recommend approving a dimensioned dieline and a filled sample instead of choosing the window from an empty mock-up alone.

Buyers should choose a zipper by matching the pet food format, pouch size, consumer opening habits, filling equipment, seal area, and required reclosure performance. We recommend testing filled samples on the actual packing line before approving bulk production.

I recommend that buyers include the packed product, pouch format, dimensions, fill quantity, filling and sealing method, material needs, artwork status, SKU quantities, sample expectations, destination, and target schedule in every custom flexible packaging RFQ.
