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.

I approve a retort pouch only after the food, process, pouch structure, sealing conditions, residual air, post-retort integrity, and distribution tests are validated together. I record the accepted materials, dimensions, seal settings, samples, and change controls before bulk production.

I choose spout diameter by matching product viscosity, particle size, target dispensing speed, fill method, cap system, and equipment limits. I then test the actual product in a filled pouch before confirming mass production.
