Zipper, spout, or valve? Start with the function.

Zipper: plan use after opening

Will customers use everything at once or return to the pack? That question helps define the need for reclosure. Discuss the contents, opening size, and how the product is removed. The zipper must be considered alongside the seal position and body construction.

Spout: consider how the contents are dispensed

Spout size and position relate to product flow, particles, and the intended use. Include filling conditions when discussing options. A visually attractive spout is not automatically the final choice for your product.

Valve: discuss gas-release requirements

A one-way degassing valve is designed to release gas from inside a pack while limiting entry of outside air. Its need depends on the product and process, rather than on making every coffee pack look as though it has a valve.
