What are the three (3) physical evaluations for defects in primary packaging?

Critical Defects

Physical Evaluation:

Prevents the glass bottle from performing their intended function of safely holding the product causing danger to consumers.

Major Defects

Physical Evaluation:

Make handling of the bottle difficult (ex. durability).

Minor Defects

Physical Evaluation:

Adversely affect the appearance but not the function of the bottle.

Vernier Caliper

Measure the height and diameter of bottles.

Closures

Hair-like string inside the bottle.

Split

Critical Defect:

An open crack staring at the top of the finish (top) and extending downward.

Poor Distribution

Critical Defect:

Uneven thickness of glass.

Soft Blister

Critical Defect:

A thin walled bubble in glass.

Cracks

Critical Defect:

Partial fractures.

Pinhole

Critical Defect:

Any opening causing leakage.

Chipped Finish

Critical Defect:

Pieces broken out of the top edge in the manufacturing process.

Contamination of foreign materials

This occurs when unintended substances are present in the product or its packaging, potentially compromising quality and safety.

Mismatch

Major Defects:

When the bottle and its closure do not fit properly.

Fin

Major Defects:

A thin, raised edge of excess glass on the bottle surface.

Out of round finish

Major Defects:

A pinch, flattened, or oval finish.

Stone

Major Defects:

Small inclusion of nonmelted material.

Rocker Bottom

Major Defects:

Warped bottoms which makes bottle unstable when placed on a flat surface.

Sunken (Dropped Shoulder)

Minor Defects:

Shoulder not fully blown, sagged after blowing.

Tear

Minor Defects:

A small crack or split in the bottle that does not affect its overall integrity.

Washboard

Minor Defects:

Heavy glass on one side of the bottom.

Seeds

Minor Defects:

Small bubbles in the glass.

Critical Defects

Defects that can cause serious harm or product failure and make the item unsafe for use.

Major Defects
