PKSC 1020 TEST 2 EXAM UPDATED
QUESTIONS AND CORRECT ANSWERS.
Flexible laminates - ANS purpose is to combine best properties into a single structure
flexible laminated films properties - ANS structural, barrier, aesthetic, cost, sealing
flexible laminated films performance properties - ANS machinability, coefficient of friction,
body and dead-fold properties, tear, thermoforming, use environment
the lower the COF... - ANS the less energy involved
VFFS - ANS vertical form fill seal
HFFS - ANS horizontal form fill seal
Vertical form fill seal - ANS has vertical orientation, makes pouches (capri sun, ketchup
packs)
horizontal form fill seal - ANS not as fast as VFFS, don't have to seal the bottom
permeability equation - ANS volume (mL) and thickness (mil) divided by area per day

, methods of combining materials - ANS laminating, wet bonding, dry bonding, holt melt,
extrusion, coating, coextrusion
gravure coating - ANS metal cylinder has pits in it, coated into whatever (ink, wax), the pits
pick up the coating
extrusion lamination - ANS 3 layers laminate, substrate C is the melted polymer coming off
the extrusion dye, the three-ply laminate is what is sold
wet bond lamination - ANS wet or dry depends on the type of adhesion being used, wet has
1 unwind on the left which is passed over the glue and picks up substrate B, then sent to the
drying tunnel
dry bond lamination - ANS both dried before glued together, some glues have to set/dry
laminate constructions - ANS read outside to inside, first layer is the outside layer which you
can touch, outside is the material directly in contact with the product
plastic terminology - ANS 100 gauge=1 mil=0.001 inches
paperboard terminology - ANS points; 1 point=0.001 inches; above 12 points
metals terminology - ANS mils; 1 mil= 0.001 inches
micrometers terminology - ANS 1 micrometer=1x10^-6 meters
ream of paper terminology - ANS 3000 ft squared
primary - ANS contains product
