Established in 1976, COSJAR brings decades of experience in plastic beauty packaging, supported by manufacturing facilities in Taiwan and China to ensure consistent quality, stable lead times, and reliable production control. We focus on mono-material and refillable packaging, functional airless solutions, and droppers—helping R&D teams balance sustainability targets, material clarity, product compatibility, and functional performance throughout development and scale-up. For selected solutions, PCR material options are available at adjustable percentages to support internal testing and specification needs.
With in-house decoration capabilities—including varnishing, hot-stamping, and multiple printing services—plus private mold development, we support both standard and bespoke projects. COSJAR is strongly aligned with ESG principles through internationally recognized management systems and ISO9001/14001 & SA8000 certs.
COSJAR partners with global beauty brands to develop responsible packaging solutions aligned with evolving sustainability, quality, and performance expectations.
