BOTTLE SCHOOL | SECTION 4 KNOWLEDGE CHECK
From Design to Finished Package

Section 4 Knowledge Check

Congratulations on completing Section 4 of Bottle School!

You've learned how plastic bottles are manufactured, what preforms and parisons are, how packaging can be decorated and customized, what quality control involves, and how packaging availability works.

Now put that knowledge to the test with five questions.

How It Works

Select one answer for each question. When you've answered all five, select Check My Answers.

You'll immediately see your score, the correct answers, and an explanation for each question.

There is no required passing score. You can review the material and try again as often as you like.

Manufacturing, Quality & Availability

1. What is a PET preform?

A PET preform is an injection-molded starting shape. During stretch blow molding, its body expands into the final bottle shape. The preform's neck finish is generally retained.

2. Which manufacturing process begins with an extruded hollow tube called a parison?

Extrusion blow molding forms a hot, hollow parison. Air expands it inside a mold to create the finished container. Injection stretch blow molding instead uses a preform.

3. A brand wants to add new graphics to an existing bottle without changing its physical shape. Which is a possible solution?

Pressure-sensitive labels or suitable direct printing can change the appearance of an existing bottle. New mold tooling is not automatically required for a decoration change.

4. A bottle has the correct gram weight. Does that guarantee its wall thickness is distributed correctly?

Gram weight measures the overall mass of the empty container. It does not establish that material is distributed appropriately throughout the bottle.

5. A bottle appears in a special-order catalog and has an existing mold. What can you conclude?

Existing tooling does not automatically mean finished bottles are in inventory. Minimum order quantity, tooling access, materials, production schedules, and lead times still need confirmation.

Great Work!

Coming Up Next

Section 5 — Putting Knowledge Into Practice

You've learned about bottles, materials, neck finishes, closures, molding, decoration, quality, and availability.

In our final section, we'll bring these concepts together and explore how to approach a real packaging project.

Lesson 16: Choosing the Right Packaging Solution

Lesson 17: Planning a Packaging Project

Lesson 18: Putting It All Together

After these lessons, we'll complete the final Bottle School Knowledge Check.
