Question 1

Which sealing method uses ultrasonic energy to bond thermoplastic packaging materials?

Accepted Answer

Ultrasonic welding

Answer

Ultrasonic welding converts high-frequency electrical energy to mechanical vibration that generates frictional heat to bond thermoplastics.

Question 2

A form-fill-seal (FFS) machine that forms pouches from a flat roll of film and seals them horizontally is classified as:

Accepted Answer

Horizontal FFS (HFFS)

Answer

Horizontal FFS machines process film in a horizontal orientation, forming, filling, and sealing pouches side-by-side along a horizontal path.

Question 3

What does 'OEE' stand for in packaging machinery performance measurement?

Accepted Answer

Overall Equipment Effectiveness

Answer

Overall Equipment Effectiveness (OEE) is calculated by multiplying Availability × Performance × Quality to give a composite machine efficiency score.

Question 4

In a rotary capping machine, what component applies consistent torque to ensure proper seal integrity without over-tightening?

Accepted Answer

Magnetic clutch

Answer

A magnetic clutch slips at a preset torque value, ensuring caps are tightened to specification without damaging closures or containers.

Question 5

Which type of conveyor uses a series of interconnected flat plates and is commonly used to transport glass bottles in high-speed packaging lines?

Accepted Answer

Slat conveyor

Answer

Slat conveyors use rigid interlocked slats that provide a stable, flat surface ideal for transporting heavy or unstable containers like glass bottles.
