Heat Sealer
Introduction of Heat Sealer

The STH-3 Heat Sealer utilizes a heat press sealing method to determine key parameters such as sealing temperature, sealing time, and sealing pressure for plastic film substrates, flexible packaging composite films, coated paper, and other heat-sealing composite films. It provides users with precise heat-sealing test indicators. The control system is fully digital, and key components are sourced from internationally renowned brands, offering a high degree of automation and ease of operation.
