Edible film adalah alternatif ramah lingkungan yang menjanjikan untuk menggantikan bahan kemasan plastik sintetis. Penelitian ini bertujuan mengevaluasi pengaruh bubuk teh hijau terhadap karakteristik edible film berbasis whey-gelatin. Penelitian menggunakan rancangan acak lengkap dengan tiga perlakuan: P1 (5%), P2 (10%), dan P3 (15%), masing-masing dengan tiga ulangan. Hasil menunjukkan penggabungan bubuk teh hijau secara signifikan memengaruhi waktu gelasi dan kelarutan film (P<0,01). Waktu gelasi berkisar antara 9 menit 56 detik hingga 17 menit 32 detik, sementara nilai kelarutan berkisar antara 43,31% hingga 45,87%. Penambahan teh hijau juga memengaruhi mikrostruktur film, memperbaiki fitur permukaan dan memperkuat matriks polimer. Konsentrasi optimal bubuk teh hijau adalah 5%, menghasilkan waktu gelasi lebih singkat (9 menit 56 detik) dengan kelarutan 45,87%. Temuan ini mendukung potensi edible film berbasis whey-gelatin sebagai bahan kemasan ramah lingkungan yang biodegradable.
