  • Politics/Legal
  • Socio-cultural Factors
  • Demographics
  • Ecology
  • Raw Material Availability
  • Economics

The Role of Packaging

  • Mass production of packaged food has been enabled by technological innovations.
  • Economies of scale and competition have made many products more affordable.
  • Consumer demand for pre-packaged food has increased alongside global population increases.
  • Large retail groups and food service industries have evolved in response to lifestyle and logistical changes.
  • Sourcing of products around the world is increasingly assisted by reduced trade barriers.
  • Packaging is integral to logistical systems and prevents or reduces waste in the food supply.
  • It assists in preserving resources by preventing spoilage and protects products until consumption.

Essential Functions of Packaging

  • Containment: Depends on the product’s physical form and nature.
  • Protection:Prevents mechanical damage.
  • Preservation: Prevents chemical changes and microbiological spoilage.
  • Information: Includes legal requirements and ingredient lists.
  • Convenience: Facilitates pack handling for end user.
  • Presentation:Involves material, size, colour and merch display units.
  • Brand communications: includes pack persona.
  • Promotion (Selling):Includes free product new product etc.
  • Economy: Includes Efficiency in Storage
  • Environmental Responsibility include reuse etc

Packaging Strategy

  • Delivers safe products in line with organizational strategies and objectives

Packaging Design and Marketing

  • Is a prerequisite that includes a marketing pull in order to succed.
