Warping, Shrink Tension and Storage Pressure

How stacking, tight wrap and shrinking plastics distort boxes, jackets and cards.

Factory-sealed collecting rewards careful identification and restraint. The same visual sign can be normal on one product and suspicious on another, so category-specific comparison matters more than generic “reseal tricks.”

1. Support evenly

Support evenly should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

2. Avoid heavy stacks

Avoid heavy stacks should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

3. Use correctly sized protectors

Use correctly sized protectors should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

4. Inspect shrink tension

Inspect shrink tension should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

5. Store vertically where appropriate

Store vertically where appropriate should be evaluated against the exact category, era, package format and documented factory variation. Preserve evidence, photograph before handling and avoid turning one visual clue into a definitive authenticity claim.

Preservation rule: Do not open, peel, puncture, heat, rewrap, flatten or chemically treat packaging to test authenticity or improve appearance.
