2
Packaging and the Food Environment

• A brief perspective to demonstrate the key roles
  played by food packaging in meeting consumer food
  and nutrition needs and desires better than at
  any time in history, at lower cost and with less
  environmental insult and disruption

3
Packaging

• Packaging separation of the product from an
  environment attempting to return products to
  their original states - indispensable to the
  distribution of all consumer and most industrial
  goods
• Without packagingindustrialized society could
  not exist
• With packagingconsumer and industrys goods are
  delivered

4
Packaging

• A holistic system comprehending
• The productalways the primary consideration for
  packaging
• Protection against an always hostile natural
  environment
• Physical structure
• Equipment to marry the package structure to the
  product
• Consumer/customer use
• Distribution channels
• Safety
• Minimization of environmental insult
• All at an economic price

5
Food Packaging

• Food packaging protection for safety, quality
  retention
• Without food packagingindustrialized society
  could not eat
• With food packagingindustrialized society
• Less than 4 of the population is employed in
  agriculture
• Delivering the safest, highest quality food
  supply in world history
• Broadest variety of food imaginable
• Convenience for consumers to prepare, serve and
  eat

6
Food Packaging

• Food today is at its lowest cost in world history
• Less than 11 of disposable income
• Even with away-from-home eating
• Packaging costs less than 7 of retail price of
  food
• And we strive to continuously reduce the cost of
  food and its packaging

7
Food Packaging

• And, despite the consumer desire for more
  convenience, the weight of packaging per unit of
  food contained is the lowest in history
• As heavier-weight glass, metal, and high-caliper
  paperboard structures decline
• And lightweight plastic and flexible structures
  grow

8
Food Packaging

• Nearly 60 of all packaging is used to protect
  our food supply
• 40 of packaging is paper and paperboard and
  static in growth
• More than half is recaptured
• Most is recycled
• Returns to become new packaging
• A recycling infrastructure has been operational
  for gt 100 years
• 20 of packaging is plastic and growing

9
Food Packaging

• Purpose of Food Packaging
• Protectionagainst natural environment
• Oxygen
• Moisture
• Water
• Microorganisms
• Light
• Dirt
• Odors
• Animals
• Humans
• Without this protection, food waste would be over
  50

10
Food Packaging

• Purpose
• Protectionagainst distribution environment
• in-plant trucks, rail cars, ships, in-store,
  etc.
• Impact
• Vibration
• Compression

11
Food Packaging

• Purpose
• To ensure microbiological and chemical product
  safety
• To retain initial product quality
• Nutritional value
• Sensory characteristics
• In conjunction with distribution, to deliver the
  product intended by the food processor/marketer
• To permit commercial shelf life

12
Food Packaging

• Microbiological safety
• Despite the headlines, our food supply is the
  safest in world history and becoming safer
• But, too many people die/become ill
• Food science and technology strive to ensure food
  product safety in conjunction with
• Processing
• Packaging
• Distribution

13
Food Packaging

• Further purposes
• Communication
• Mandatory
• Marketing in a competitive environment
• Portioning
• Dispensing
• Unitizing
• Meet legal and regulatory requirements

14
Why Food Packaging?

• The guidelines for food packaging
• Safety
• Protect the contents
• Consumer convenience, ease of access and use
• Facilitate finding on 100 000 self service retail
  outlets
• Attractive to a diversity of consumers
• Also applicable for away from home eating half
  of all food consumption
• And to minimize insult to the environment

15
Plastics and Packaging

• To reduce the mass of material to protect the
  contents
• Intimate marriage of materials for functionality
• Polyethylene plus plastic and/or paperboard
• Ethylene vinyl alcohol (EVOH) oxygen barrier
• Polyester (PET) for carbonated beverage packaging
  displaced glass
• Hot-fill high acid fluid foods, e.g., tomato
  paste, into laminated flexible pouches displaced
  metal cans
• Retortable plastic trays and cans for low acid
  foods, e.g., macaroni and cheese
• Microwavable and dual-ovenable packaging
• High technology food packaging

16
A 20th Century Technology Aseptic Packaging

• Aseptic packaging
• Product sterilized with little heat package
  sterilized independently and assembled in sterile
  conditions to deliver higher quality product
• Composite paperboard bricks
• Juice
• Milk

A Brief History of Food Packaging

• In the beginning, packaging was
• Leaves
• Skulls
• Animal skins
• Pottery
• Amphorae
• Glass
• And so, little food was packaged
• And farming was mans and womans principal
  activity
• And, under the stresses, humans did not live well
  or long

95
The Nineteenth Century for Food Packaging

• Appert, Durand, Kensett were key to the emergence
  of canning
• Pasteur related microorganisms to spoilage
• Underwood, Prescott developed the scientific
  basis of thermal processing to sterilize foods
  valid today
• Linkages were established among
• Product
• Process
• Package
