The BOPP films are packaged in a tray. The outside of the package is wrapped with a film, while the internal films are protected by three waterproof and dustproof layers. Package transport and stevedoring are all mechanized.

Ningbo Great Southeast Wanxiang Science and Technology Co.,Ltd. supplies BOPP capacitor films with superior dielectric properties. DDN has employed four BOPP capacitor film automatic production lines from Bruckner company (Germany) featuring excellent performance in winding capacity, dielectric breakdown strength and saturating properties. Additionally, DDN is equipped with stable production lines ensuring large annual output and JIT delivery. We also utilize highly advance testing instruments and professionals to guarantee the rate of BOPP capacitor films.
