A package is the container, wrapper, or enclosure that holds a food product for sale, and as a verb, to package means to place food into such containers attractively and protectively. Packaging performs multiple jobs simultaneously: it protects against contamination, moisture loss, and physical damage; preserves freshness through barrier films and modified atmospheres; carries mandatory information including ingredients, allergens, nutrition, and date marks; and markets the product through design, colour, and branding. Materials range from glass, metal, paper, and board to multilayer plastics, each chosen for barrier properties, cost, and environmental footprint. The sector faces intense pressure to reduce single-use plastic while maintaining food safety and shelf life, driving innovation in recyclable, compostable, and lightweight formats. Packaging failures, from leakers to seal defects, remain a leading cause of food waste and recalls.
