3.2. Gluing and Thermal Bonding

Try these first

1. 1.

   What is gluing?

   Hint

   Think of how glue sticks things together.

2. 2.

   What does thermal bonding involve?

   Hint

   Remember the melting point of plastics.

3. 3.

   What is the main purpose of gluing?

   • To join layers with heat
   • To join layers chemically
   • To cut materials

   Hint

   Remember what glue is used for!

4. 4.

   Thermal bonding is primarily achieved by which method?

   • Chemical interaction
   • Heating materials
   • Mechanical pressing

   Hint

   Think about melting plastics together.

5. 5.

   Design an experimental procedure to test the strength of different adhesives on various materials.

   Hint

   Consider how to quantify strength—what measuring tools might you use?

6. 6.

   Propose a package design that utilizes both gluing and thermal bonding techniques.

   Hint

   Think about how layers can enhance strength and product protection.
