Metal Closure Types
|
Threaded
Lug Style Roll on Press on Crown Friction fit |
|
|
Roll on Cap threads
|
are formed by forcing the aluminum shell to conform to bottle finished threads.
|
|
|
Press on/twist off closure
|
utilizes a plastisol that expands during steam vapor vacuum sealing to become, in effect, a threaded closure.

Packaging Machinery
|
-Uses packages but does not make them
-Includes code marking but does not include printing in general. |
|
|
Machinery converting
|
Makes the package, so converting operations not considered part of packaging machinery.
|
|
|
Often individual machines are made by different companies but must operate together in a packaging line.

|
|
Machinery line speed
|
What really counts is the output
|
|
|
Filler is a critical operational unit in a production line and is frequently used as the benchmark from which all machine speeds are derived.
|
True
|
|
|
machines run at 100% efficiency
|
False
|
|
|
Calculating CPM
|
effiency of each machine x cpm of slowest machine = actual cpm
|
|
|
Machinery- Accumulator
|
Isolates the slowest station and increases output. Improves output.
|
|
|
The more accurate the filler, the smaller the standard deviation and closer the filler can be set to the declared fill
|
True
|
|
|
Because many containers vary slightly in their actual volumes, filling to a constant volume results in visible fill-level differences
|
True
|
|
|
Constant Fill level
|
Higher probability of giveaway
use for transparent packages for inexpensive product |
|
|
Constant Volume
|
Less giveaway
For opaque packages expensive product |
|
|
Gravity Fill
|
Slower than a vacuum fill and used for products that foam a little.
|
|
|
Vacuum Fill
|
Seal package to filler, starting vacuum which pulls product into package.
|
|
|
Pressure and vacuum fill
|
Used for thick and foamy products
|
|
|
Piston Filler
|
Used for thick, paste products and liquids.
|
|
|
Net weight fillers
|
Includes weight of package and product
|
|
|
Net Weight Fillers
|
Weighs product only
|
|
|
Gross weight fillers
|
faster but also has more chance of giveaway
set scale for heaviest possible package weight so you never sell underweight |
|
|
90-100% of next day air parcels are dropped 30"
|
True
|
|
|
Lighter weight packages have to be dropped from lower heights.
|
False
|
|
|
Average IMPACT speed is
|
5 mph
