What is fireproof bag?

Fireproof bag is a device used to prevent the spread of fire, usually made of flame retardant materials, which can inhibit the spread of flame and heat, thereby reducing the losses caused by fire. They are used in a wide range of places and situations, from homes to commercial buildings, to industry and the military.

The structure and principle of fireproof bags:

The structure and principle of fire-resistant bags are designed to protect their contents from fire and high temperatures in the event of a fire.

The following is the general structure of a fireproof bag:

Outer layer of fireproof material: The outer layer of fireproof bags is usually made of materials with fireproof properties, such as fiberglass, fireproof coating, etc. These materials can resist flames and high temperatures to a certain extent and slow down the spread of fire. Flame retardant Velcro is a special kind of Velcro, which improves its fire resistance by using flame retardant materials. This material does not ignite easily when it comes into contact with a fire source, and maintains its structural stability even under extreme conditions, preventing the spread of fire through the sealing site. Flame-retardant Velcro makes the opening and closing of the fireproof bag easier, while ensuring the safety of the contents of the bag in the event of a fire. Flame retardant zippers are zippers made of traditional zippers with special treatment or select specific materials to enhance the overall fire resistance of fireproof bags. This zipper will not easily melt or damage at high temperature, and can remain closed, so as to isolate the outside flame and heat to a certain extent, and protect the items in the bag. The use of flame retardant zippers is one of the important measures to improve the protective effect of fire bags. Flame retardant edge strip is a special material used for the edge of a fire resistant bag, which enhances the fire resistance of these potential weaknesses by covering the seams and edges of the bag. This wrapping strip material maintains its structural integrity at high temperatures, preventing flames from penetrating or entering the bag along gaps. Through the use of flame retardant wrapping strip, can effectively improve the overall sealing and fire resistance of fire bags. Fire-resistant bags are usually made with high-temperature-resistant seams to ensure that the entire bag is not easy to break or crack in high-temperature environments, which enhances the durability of the fire-resistant bags.

Inner layer of high-temperature insulation material: The inner layer of the fire-proof bag is made of high-temperature insulation material, such as glass fiber, ceramic fiber, etc. These materials have good thermal insulation properties and can effectively isolate external high temperatures and prevent internal items from being heated.

Sealing design: Fireproof bags usually adopt a sealing design to ensure that the internal space is isolated from the outside world and prevent flames and high temperatures from directly entering the interior. This design helps protect the contents inside from fire.

Waterproof function: Some high-end fireproof bags are also equipped with waterproof function, which can prevent moisture from intruding inside to a certain extent. This design provides protection during fire extinguishing or in the event of water damage caused by a fire.

Working principle:

When a fire occurs, the outer layer of fire-proof material of the fire-proof bag can block flames and high temperatures, slowing down the spread of fire. At the same time, the inner layer of high-temperature insulation material can effectively isolate the external high temperature and protect the internal items from being affected by heat. The sealed design ensures that the internal space is isolated from the outside world, preventing flames and high temperatures from directly entering the interior. During the fire extinguishing process, the waterproof function of the fire-proof bag can also protect the contents inside from water damage. Taken together, the fireproof bag provides effective fire protection for the contents inside through multiple protection mechanisms such as outer fireproof material, inner high-temperature insulation material, sealing design and waterproof function.

Application scenarios:

The application scenarios of fireproof bags are very wide. In families, people often place fireproof bags in fire-prone places such as kitchens and bedrooms in case of emergency.

Fire-resistant bags are also widely used in commercial buildings and public places as part of fire-fighting equipment to respond to fire emergencies and ensure the safety of people's lives and property.

In the industrial field, fireproof bags are often used to store and transport flammable and explosive items to prevent fire accidents.

Even in the military field, fireproof bags are used as protective equipment to protect soldiers from fires and explosions on the battlefield.

Explosion-proof fireproof bag：Explosion-proof fireproof bag is a safety bag specially designed for storing and transporting flammable and explosive items, such as lithium batteries. These bags are usually made of high strength, high temperature resistant materials, which can effectively prevent the occurrence of fire and explosion, and contain the fire inside the bag, reducing the damage and danger to the surrounding environment.

In addition to the above application scenarios, fireproof bags also have some other special uses. For example, in some outdoor activities, people can carry foldable fireproof bags to temporarily build firewalls or block fires to deal with the risk of fire caused by wild campfires. In addition, some cars and aircraft are also equipped with fireproof bags to respond to emergencies when a vehicle or aircraft fire occurs and ensure the safety of passengers and crew.

Where can you bulk purchase fireproof bag in China?

You can purchase fireproof bags at Proway, which are constructed with the following materials: an outer layer of silicone-coated fiberglass cloth, an inner layer of fiberglass cloth, and aluminum foil. They are equipped with flame retardant magic stickers, flame retardant zippers, and flame retardant edge strips. These bags have a high temperature resistance of up to 550°C.
