Spices demand strong barriers to protect volatile oils and colour. Foil and high-barrier films help lock in potency. Clear windows showcase grinds and blends while aiding selection. Small to medium formats fit kitchen use and gift sets. Resealable zips support freshness and dosing control. Kraft styles deliver a natural, gourmet aesthetic. Heat-sealed seams add tamper evidence. Ideal for blends, rubs and seasoning kits.
