What the lab reports found.

Independent SGS reports record results for finished bamboo-paper samples supplied by the manufacturer. Every finding below is paired with its report number and date.

At a glance

PFAS, formaldehyde, BPA, BPS and eight named heavy metals were not detected in the submitted samples.

Separate checks on a natural-colour paper sample recorded negative fluorescent matter under UV and Grade 5, no transfer.

“Not detected” means the measured result was below that laboratory method’s detection limit.

How to read the evidence.

What the findings cover

The results apply to the submitted paper samples and the laboratory methods named in each report.

The boundary

The reports do not test every possible substance or guarantee an identical result for every production run.

Why the manufacturer appears

The samples were submitted at manufacturing level, so the reports identify the manufacturer rather than the BAMBUM retail brand.
