Types of Containers
Primary Come in direct contact with the food
Secondary Outter box or wrap that holds several
secondary containers together Tertiary
Group several secondary holders into shipping units
Packing Materials and Forms Metal Plant matter (paper and wood) Glass Plastic
Cans
Formed at the food processing factory or shipped with bottoms attatched and separate lids
Lids are later seamed onto the cans
Can Make-Up
Outside protected from rust by a thin layer of tin (.025% by weight)
Inside is protected by a thin layer of tin or baked-on enamel
Tin-free steel and thermoplastic adhesive-bonded seams have become more common to do away with solder and possible traces of lead in food.
Tin is used due to its lightweight, low levels of rust, recyclability, and ease of shipping
Glass
Chemically inert Noncorrosive Recylable Reusable in the cases of home canning Downfalls
Breakable Recyling is not always easy
Paper
Must be treated, coated or laminated when used as a primary container
Paper that comes in contact with food must meet FDA standards for chemical purity
Paper used for milk cartons must come from sanitary virgin pulp
Major safety concern is papers puncturability that will allow for the outside environment to enter and contaminate the food
Plastics
Popular Copolymer plastics extend the range of
useful food packaging applications Ionomer plastic materials are improved
food-handling materials that function under greater oil, grease, solvent resistance, and have a higher melting strength
Newer plastic materials contain cornstarch to make them more biodegradable
Laminates
Made up of layers of different materials Typically in this order
1. Polyethylene 2. Polyethylene 3. Aluminum foil 4. Polyethylene 5. Paper 6. Polyethylene
Edible Films
Used in sausage casings, breakfast cereal raisins and nuts
Edible wax films are also used on fresh vegetables to reduce mouisture loss and provide resistance to the growth of molds
Packages with Special Features Freezable Microwavable Squeezable Aseptic packaging
Sterile liquids that once packaged do not require refrigeration like fruit juices

Environmental Considerations Aluminum most recycled Plastic
Type of plastic is identified within the recycling logo by numbers 1-7 Example: 1 refers to PET the plastic used to
produce large 2-liter soda bottles Important in all parts of the packaing
industry due to environmental regulations

Activity
Take a potato chip out of a package and describe what it looks, feels and sounds like when broken. Taste it, what does it taste like?
Let a potato chip set outside the packaging over the long weekend, when we return on Monday look at the chip and describe it again. What does it look, feel and sound like when broken? Taste it, what does it taste like?
Compare the results and relate the differences in the potato chip from when you took it out to a few days later, to its packaging.
