Usually not.
A laboratory report, compliance statement, and third-party certification are different things. Certification may apply only to a specific resin, film, thickness, color, or product configuration.
The final branded product may include:
- different thickness;
- different pigment;
- printed ink;
- adhesive;
- zipper;
- label;
- carton or accessory.
Those changes can affect whether the finished product is covered.
Before using any certification logo, the brand should confirm:
- the certificate holder;
- product scope;
- allowed private-label or sublicense arrangement;
- covered thickness and formulation;
- current validity;
- labeling rules.
The final package should be approved, not assumed.
