Fireproof file bag:
It prevents important documents and data from being burned in fires occurring at home, companies, government offices, archives, or during express delivery, thus avoiding severe losses. If these important documents are stored in this fireproof bag, they will not be damaged by fire-even in the event of a blaze-because the bag can withstand high temperatures up to 700°C.
Fireproof file bags are mainly used for storing various critical documents in personal collections, company archives, and government record rooms, such as ID cards, passports, contracts, checks, and other valuable documents.
This product is composed of three layers, all of which are Class A1 non-combustible fireproof materials:
- Middle layer: Fiber cotton, with high-temperature resistance up to 700°C;
- Surface and inner layers: Fiber cloth, with high-temperature resistance up to 500°C;
- Sewing thread: Also a fireproof component, with high-temperature resistance up to 380°C.
- As a fire-insulating product designed to protect documents from fire sources, the fireproof office file bag primarily aims to delay document damage. It allows users to have more time to rescue important items.
