Shrink Wrap and Factory Seams

Why seam style can help but cannot authenticate every category by itself.

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. Different factories vary

Different factories vary 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. Age changes plastic

Age changes plastic 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. Rewrap equipment exists

Rewrap equipment exists 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. Retail overwrap can confuse

Retail overwrap can confuse 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. Compare known originals

Compare known originals 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.
