I've worked with Custom Packaging Lane a few times this year on packaging for our soaps. They always deliver great looking boxes within our tight deadlines. Frank is super communicative and a pleasure to work with.

Very happy with Custom Packaging Lane. Sam and Sarah were great to work with. The quality of the printing and speedy delivery was very much appreciated. I use them for 2 of our custom printed boxes and will be using them for more projects moving forward. Sam was wonderful and even caught a typo that I missed. Thank you.

A permanent top seal closes the pouch for first opening, while a zipper lets the buyer reclose it afterward. Heat, pressure, and dwell settings depend on the sealant layer, film thickness, jaw design, line speed, and material inside the seal area.
Seal planning begins above the zipper, tear notch, or hang hole. Powder, oil, crumbs, and folded film in that zone can create channels or weak spots. Production checks commonly inspect continuity, wrinkles, burns, and peel behavior, then repeat the check after the filled pouch has cooled. If contents will touch the film, ask us about food-contact options for the intended product.
A foil laminate can pair a printable outer web with a barrier center and a heat-sealable inner web. The exact construction should follow the product, filling conditions, target shelf environment, and sealing equipment rather than the word Mylar alone. A foil layer also changes how metallic areas and white ink appear in print.
Layer count by itself does not prove seal strength. The converter must keep the chosen inner web compatible with the jaw temperature and dwell window, while the packer must keep product dust and oil out of the seal zone. A mockup made from production-intent film gives a more useful result than testing an unrelated stock pouch.
Width, finished height, gusset depth, and usable fill height are the four measurements that control pouch capacity. Stand-up pouches are commonly 3 to 7.5 inches wide, but the correct format comes from filled product volume and headspace, not front-panel width alone. Usable height excludes the top seal area, zipper track, and any hang-hole zone.
| Pouch format | Construction | Typical packing use | Final closure |
|---|---|---|---|
| Three-side seal pouch | Three factory-sealed edges and one fill edge | Flat portions and samples | Cross seal at the fill edge |
| Stand-up pouch | Bottom gusset opens into a base | Products displayed upright | Top seal, often above a zipper |
| Center-fin pouch | Longitudinal back seam with end seals | Continuous form-fill-seal lines | Upper end seal |
| Die-cut pouch | Shaped perimeter rather than a rectangle | Distinct display silhouettes | Seal zone follows the approved profile |
The broader bag collection gives format context, while custom vacuum seal bags and custom food storage bags show related flexible package directions. Test actual fill weight because dense granules, light powders, and irregular pieces occupy the same nominal volume differently.
Graphics can be reverse printed on the inside face of an outer clear web before lamination to the barrier and sealant webs, keeping ink away from handling surfaces. Flexible packaging commonly uses flexographic, digital, or gravure printing, with digital favored when short runs or multiple versions make cylinder or plate setup inefficient.
The dieline must reserve zipper, seal, gusset, tear-notch, and registration areas before the front panel is composed. Fine reverse type can fill in, weak white underprint can dull colors over metallic film, and RGB files can shift after press conversion. Approve the digital proof before tooling or print setup.
Film construction, finished size, print coverage, number of colors, zipper or valve components, finish, quantity break, and tooling are the main price drivers. A shaped perimeter can require dedicated tooling, while high ink coverage or a registered matte effect adds production steps. Compare quotations only when every supplier is pricing the same layer structure, dimensions, closure, artwork version, and delivered quantity.
Use the sample kit to compare tactile and visual options, then test a production-material mockup on the intended sealing equipment. The operating window belongs to the chosen laminate and packing line, not to the package name.
