01
Front label hierarchy
Material choice should follow product needs and brand position. Matte, gloss, windows, valves, high-barrier films, zippers, and spouts each solve different shelf, protection, and usability problems.
02
Format and structure
Sparal checks whether the structure fits finish selection, shelf-life review, window planning before artwork proofing.
03
Material and finish callout
Connects tactile feel to brand position.
04
Back panel, barcode, lot/date
Back-panel and variable-data zones are fixed before proof so quote review, artwork approval, and reorder files stay aligned.
