How do I confirm pouch features before production?
Write down how the pouch will be filled, sealed, displayed and opened. A pouch filled by hand has different space requirements from one running on automatic equipment. A pack sent through e-commerce also faces different handling from one placed directly on a retail shelf.
Mark the zipper, valve, tear notch, window and final seal on the dieline. Keep small text, barcodes and important product information away from folds, seals and cut lines. With a valve, check the space occupied on both sides of the film, not only the visible circle on the front.
Feature materials also matter. CEFLEX advises designers to align zippers, spouts, closures and valves with the material stream of the main package. Its flexible-packaging design guidance explains this point. A mono-PE bag with an incompatible zipper or valve should not automatically carry a recyclable claim.
Test the sample with the product inside. During the test, watch the filling process and check the top seal, zipper, valve, window, opening path and standing stability. Then handle or ship the filled pack in the same way you expect it to move after production. A dieline cannot show how the finished pouch will feel under load.
You can review available options on our custom flat bottom pouch page. When requesting a sample, provide the product, fill weight, material, target shelf life, filling method and the features you are considering.
