Securities Star news, Cangzhou Mingzhu (002108) responded to investors' concerns on the investor relations platform on March 31.

Investor's Question: Can your BOPA film be applied in the medical and special fields? For implantable medical devices: using its biocompatibility to develop biodegradable sutures and drug release membranes. Military materials: as a lightweight bulletproof vest substrate or corrosion-resistant ammunition packaging. Although we have not directly involved in military production, the material properties already have replacement potential. Additionally, in new energy and aerospace?

Cangzhou Mingzhu replied: Hello! BOPA film products are one of the high-end packaging materials that have developed rapidly in recent years. They are mainly used for food packaging, especially for retort food packaging, oily food packaging, frozen food packaging, liquid seasoning packaging, etc. In addition, they are widely used in general industrial packaging, pharmaceutical packaging, cosmetic and cleaning products packaging, mechanical and electronic products (such as aluminum-plastic encapsulation film for lithium batteries, packaging for some electronic products), household products (such as vacuum storage bags), balloon decorations, and packaging for some grain products.
