Important Notes:
The above data, obtained from our internal testing, is provided for reference only to assist customers in sample evaluation or product use.
The final performance of the product depends on specific production processes, and improper use may cause irreversible damage.
As equipment, processing condtions, and end-use requirements vary across manufacturers, our company shall only be responsible for the
performance of the film itself.
