The name on the box isn't always the company that coated the film. This is what the public record shows about who owns which brands and who manufactures for others, and where the paper trail stops.
Controlled by Eastman Chemical Company, which also owns Ai-Red Technology (Dalian), a film maker it bought in 2023
Ownership and manufacturing relationship confirmed in Eastman brand materials. A shared parent does not prove the films are identical.
Eastman / LLumar source ↗Madico, MaxPro and Nexfil publicly describe private-label or OEM work, and Global Hi-Tech says it manufactures for other brands. ASWF is one corroborated example in a much wider market.
The private-label ledger ↗A company can formulate, commission, distribute or warranty a film without coating it. Until the manufacturer is documented, the database says so.
The evidence standard ↗LLumar, FormulaOne and SunTek sit under Eastman, and Madico has announced it is buying Johnson. Both are on the record. The claim that matching shades are identical needs product-level evidence I haven't found.
The Reddit thread and the ownership record ↗Private label isn't a quality grade. The useful questions are who stands behind the warranty, whether revisions are traceable and whether the testing can be inspected.
How private label is reported here ↗One forum post is a tip. Repeated independent reports are a lead. Only a document, a test report, a legal entity or an on-record statement counts as proof, and only proof gets a solid line on the chart.
