PTP aluminium foil

1. Overview​

A high-performance packaging material integrating aluminum foil’s inherent barrier properties with advanced coating technology. It provides comprehensive protection against gases, moisture, light, and odor by sealing pinholes and enhancing heat-seal performance, while balancing mechanical strength and processability—ideal for long-term preservation of sensitive products.​
