BASIC FORMS AND TERMINOLOGY PACKAGING FORMS Three basic forms - Rigid o Defined shape o Can’t be deformed unless massive force exerted o Deformation will result in breakage of the package and/or permanent damage - Semi rigid o Defined shape o Can be deformed with moderate force exerted o Returns to original shape - Flexible o Takes on shape of the product o Distorted with ease o Doesn’t return to original shape (EX. Candy wrapper) Continuum = rigidsemi rigidflexible RIGID Paperboard- corrugated, spiral and convolute cans, set up boxes Metal- cans Glass- only comes in one rigid form Plastics- injection molded and some thermoformed, dependent on type of plastic CLOSURES- SET UP BOXES - Metal o Threaded: CT closures thread goes all the way down the neck of the bottle o Lug style: broken thread on jar; can pop to next one o Roll on: baby food o Press on o Crown: beer, glass bottle sodas o Friction fit/pry off: paint cans - Plastic o Some thermoset o Mostly thermoplastic o Induction seal  Nto really close but part of the seal  Foil lined inner seal is flexible form Closures- types and uses Type Uses Plug (cork) Wine, liquor Crown Beer Continuous thread Beer Roll on Beer Lug/ interrupted thread Jam/jelly Press on Baby food Other types of closures - Child resistant: tested under 5 cannot open package - Tamper evident: visible evidence if opened or tampered with - Decorative product identity - Dispenser or pump style SEMI RIGID PACKAGE FORMS Paperboard- folding cartons, backing for blister packages, egg cartons and berry boxes Plastics- extrusion/injection blow molded container, injection stretch blow molded container, thermoformed container Metal- aluminum foil; ex. Pie pans FLEXIBLE Paper- label, bags Plastic- cast and blow film Metal- foil laminate and metallized films Flexible laminates - Paper, plastics, foil and metallized - Purpose is to combine best properties into single structure FLEXIBLE LAMINATED FILMS Properties - Structural- stiffness, strength - Barrier- moisture, gasses, light - Aesthetic- metallic, clarity feel - Cost- best performance for minimal cost - Sealing- heat seal, cold seal, reseal Performance properties - Machine ability - Coefficient of friction: how materials will slide across machine during proeuction - Body and bead - Tear: 900% elongation of LDPE - Thermoforming - Use environment: boil in bag, microwave, frozen (brittle) BARRIER MATERIALS Material Moisture Oxygen LPDE Fair Poor HDPE Excellent Poor EVOH Poor Excellent PVDC Excellent Excellent Nylon Poor Good PS Poor Poor PET Fair good OPP Good Poor METHODS COMBINING MATERIALS Laminating - Wet bonding- sent to drying tunnel when still wet - Dry bonding - Hot melt- warming and melting glue at some tome - Extrusion- adds a third layer, like a wax seal Coating - Coextrusion TERMINOLOGY Thickness - Plastics- 100 gauge = 1 mil = .001 inches - Paperboard- 1 point = .001 inches - Metals- mils 1 mil = .001 inches - Micrometers (microns): 1 metric: 1x10^-6 - Paper- “pounds” comes from the basis weight of paper; also term used in converting “I put 15# of poly on this web” means ??? To answer this we need: 1 micrometer = 1 x 10-6 1 meter = 39.4 inches 1 mil = 0.001 inches (1 x 10-3 inches) How many micrometers (nanometers) in a mil? When the operator says “I put 15# of polyethylene to the web” it means….. How thick is it? Vol = h?(LxW)  h?(3000 sq. ft.) Need volume rho of PE Given rho PE = 60lb./ft2 What is the volume for 15# PE? Plug into volume equation Solve for h
