Question 1

Which filling technology is best suited for high-viscosity products like peanut butter or thick pastes?

Accepted Answer

Piston filler

Answer

Piston fillers use a positive displacement mechanism that can generate the pressure needed to move thick, viscous products accurately into containers.

Question 2

What is the function of a 'desiccant' inserted inside sealed pharmaceutical packaging?

Accepted Answer

Absorb moisture

Answer

Desiccants such as silica gel absorb moisture inside sealed packages to protect moisture-sensitive products from degradation.

Question 3

A packaging machine rated at 200 units per minute has an actual output of 150 units per minute. What is its performance efficiency?

Accepted Answer

75%

Answer

Performance efficiency = (Actual Output / Ideal Output) × 100 = (150 / 200) × 100 = 75%.

Question 4

In induction sealing, what material property of the foil liner generates the heat that bonds the seal to the container finish?

Accepted Answer

Magnetic permeability causing eddy current losses

Answer

The alternating electromagnetic field induces eddy currents in the conductive aluminum foil, generating resistive heat that melts the bonding layer.

Question 5

Which labeling technology applies labels using a 'wipe-on' method as the container passes a label applicator pad?

Accepted Answer

Wipe-on labeling

Answer

Wipe-on labeling uses a dispensing pad that contacts the label onto the container surface as it moves past, suitable for flat or slightly curved surfaces.
