PKG 221 Metal
1. What are the advantages of Metal? Recyclable
Good Barrier
Very efficient process
Easy open ends
2. What are the disadvantages of Metal? Cost of setting up production is very high
Is not a flexable process when size is consid-
ered
3. What were cans originally made of? tinplate
4. What mechanism was patented for can The crimping method
production by Max Ams in 1896? It is also called double seaming
5. Originally production of cans was ___ 10
cans/min. Today the production can be up 2500
to ______ cans/min
6. What two metals are predominately used Aluminum and steel
in packaging?
7. What is alloying? Adding elements
8. What temper classifications does steel "dead soft" (easily folded over) to stiff and
range from? springy
9. What is steel referred to as when it in a low Blackplate and it is converted to tinplate or
carbon form? What is this converted to ? tine free steel
10. What metal provides a good corrosion re- Tin, which is why it is used for plating steel
sistance? cans
11. What is Bisphenol A (BPA)?
, PKG 221 Metal
An organic compound use as a coating in
some packaging that has been linked to
health problems
12. What is Aluminum? Very abundant element
Lightweight
Good strength to weight ratio
odorless, tasteless, non toxic
Very good packaging material for these rea-
sons
Corrosion resistant
Can gain stiffness from alloying
High recycling rates
13. What are the rigid applications of Alu- Beer/pop
minum? Semi rigid trays
Tubes
14. What are the Flexible applications of Alu- Foil
minum? Metalized Film
15. How was tin plating originally conducted? The steel strip used to be simply just
dragged through molten tin. This hot dip-
ping process was replaced by ELECTROPLAT-
ING
16. How thick is the tin coating on a steel can? It is only about 0.000015 in
17. What is another way to coat steel and pro- Use Chromium
tect from corrosion? Electrolytic chromium-coated steel (ECCS or
TFS)
Same price as Tin plating
