AJ Plast

What AJ Plast does

A.J. Plast Public Company Limited (AJ Plast; BKK:AJ) is a Thailand-based, publicly listed manufacturer of specialty plastic films serving the global flexible packaging industry. Founded in 1987 and headquartered in Bangkok with manufacturing facilities in Sriracha (Laem Chabang and Pinthong, Chonburi), the company produces a broad polymer-film portfolio including BOPP, BOPET, BOPA, CPP, and metallized variants, plus a sustainable BOPLA line marketed under Earth Care Solutions.

The core technology centers on biaxially oriented and cast film extrusion combined with a proprietary metallization process using 99.99% pure aluminum and a high-level metal-coating line. The company claims this delivers up to 75% improvement in water-vapor and oxygen transmission rates (WVTR/O2TR) and more than 40% improvement in bond strength versus standard metallized films, supporting food-packaging applications requiring extended shelf life. Product variants are sold through dedicated BOPP, BOPET, BOPA, CPP, Metallized, Earth Care, and High Performance Solutions lines.

Commercially, AJ Plast operates a one-time purchase / direct-sales model through separate domestic and international export sales channels, with the Bangkok HQ handling export inquiries and the Laem Chabang facility dedicated to export production. Revenue and customer mix are concentrated in the packaging and food-packaging converter segments, with no public pricing disclosure. FY2021 reported revenue was 9,444.46 million baht against 428.62 million baht net profit (4.42% net margin, 9.07% ROE), with 440 million shares outstanding and a year-end 2021 market capitalization of 7,612 million baht on the Stock Exchange of Thailand.
