Is paper fire resistant?

This blog post will answer the question, “Is paper fire resistant” and cover topics like fire-resistant properties of paper and frequently asked questions related to the topic.

Is paper fire resistant?

No, paper is not fire-resistant.

What is the definition of paper?

Paper is a thin, sheet-like substance formed from plant fibers.

It’s made up of cellulose, hemicellulose, lignin, and fillers like caco3 and china clay in a heterogeneous combination. 

Chemical additives like starch, rosin, alum, and others are also included in this combination and are utilized according to the paper’s quality.

Paper is one of humanity’s most impressive creations. For thousands of years, it has contributed to the documentation and preservation of information.

People used to write on bamboo or bits of silk clothing before the paper was developed. Silk was also too costly for most people to purchase, despite its light weight and convenience.

Bamboo, on the other hand, was inexpensive and easily accessible, but it was difficult to use and store. It was also superior to the prior writing replacements since the paper was both cost-effective and practical.

Is it true that paper is flammable?

YES. Paper is combustible and easily burns. Paper is classified as a combustible substance in countries with building and fire rules. On the other hand, various types of paper may have different properties. As a result, the pace at which they ignite is different.

It is critical to understand what causes the paper to ignite. You should also be aware of the different types of paper you have on hand.

This aids in the selection of paper and reduces/eliminates the chance of misplacing/losing your valuable books/documents.

What causes the burning of paper?

Paper is a substance made from cellulose fibers that come in the form of a thin sheet in nature.

They obtained this cellulose fiber from a variety of sources, including rags, woodlands, and other plant-based materials. These compounds are very combustible in their dry state.

They do not, however, create paper directly from these components. Before the final product is formed, these materials are exposed to several procedures.

The Making of Paper

Cutting logs of timber into chips is a common initial step in the manufacturing of paper. These logs of wood come from a variety of plant types, including softwoods like pine trees.

They then used chemical or mechanical methods to turn the chipped woods into a pulp-like substance.

Chemical pulping includes weakening the link that binds the wood together and separating a complicated substance known as lignin from the cellulose fibers using a chemical technique. 

The lignin is subsequently dissolved in a liquid known as cooking liquor, which is then rinsed away from the cellulose fibers.

The mechanical procedure entails compressing the wood chips, which are subsequently transformed into fibers by machinery. The lignin is not removed from the cellulose fibers during this procedure.

The existence of this lignin causes the paper to yellow & weaken.

The wet pulp from any of the foregoing procedures was then transported to a paper machine. They then pressed and dried it repeatedly to eliminate the water.

Finally, the dry sheet of paper is cut into various sizes depending on their intended use.

Depending on the kind of pulp used, different papers have different density and thickness characteristics. This has an impact on their flammability and application. Let’s have a look at some various papers and their qualities.

Types of paper

Types of paper are listed below:

  • Glossy paper
  • Blotting paper
  • Bond paper 
  • Cardboard paper
  • Copier paper

I will now elaborate on the guidance given above.

Glossy paper: 

This kind of paper is lustrous and is utilized in periodicals, flyers, and brochures. It’s produced from a pulp-based substance that’s about 90% of the way through.

At 250 gm, the typical glossy paper has a thickness of 0.23mm. It’s made from kaolin (white mud) and caco3.

The addition of calcium carbonate, a non-flammable material, reduces the total paper’s flammability.

Blotting paper: 

Cotton pulp is often used to make this sort of paper. Organic liquids, such as oil and ink, may be absorbed.

They’re commonly used in cosmetics to soak up excess oil from the skin.

This sort of paper has an average thickness of 0.35mm and a weight of 192gsm. Because they are produced entirely of cotton, they are weaker yet more combustible than paper created from low-grade wood pulp.

Bond paper: 

This kind of paper is formed from cotton pulp, although it is not totally comprised of it. They’re mostly employed as currency papers, letterhead stationery, and other office machinery.

The tissue paper may be made from wood fiber or recycled materials like cardboard and newspapers. A blend of recycled paper products and wood pulp may also be used to make it.

It is light, weighing between 10 and 45 grams per square meter. When compared to standard office paper, they are very combustible.

Cardboard paper

Cardboard paper is created from a combination of pulps obtained by chemical, mechanical, & semi-mechanical processes. Because it has been mechanically pulped, it is high in lignin, which accounts for 5percent of the total pulp.

It also has ash content, which varies in chemical and physical properties according to the kind of wood utilized.

It is thicker than most ordinary paper, with a density ranging from 250 to 1000gsm depending on the use.

It’s often used to make product boxes and other packaging materials. When compared to standard office paper, it is less combustible.

Copier paper: 

This sort of paper may be bought practically everywhere and is widely used. They are printing papers that may be used at home or in the workplace.

They usually include cellulose, caco3, and a material called china clay in them. At 100gsm, the typical copy paper has a thickness of 0.08mm.

Even though their qualities are dissimilar, many papers are combustible. When compared to tissue paper, cardboard may burn more slowly. They are, nevertheless, still combustible.

As a result, it’s best to remain away from fire and fire-causing substances, particularly if you’re protecting a vital piece of paper.

When the population of old papers in your area becomes out of hand, you could attempt to get rid of them by burning them. However, there is no way to get rid of them by burning them.

Burning paper, particularly on a big scale, has several environmental and health consequences. It produces a variety of problems, including air pollution, water contamination, and soil contamination.

Recycling papers is a preferable alternative to burning them. Paper trash may also be transformed into biomass fuel, which is a dependable and sustainable energy source.

What does burning paper mean when it comes to chemical change?

Paper is burned in the combustion process. Combustion is a chemical process that occurs when a hydrocarbon & oxygen come into contact. When a reaction happens, heat & light energy are released.

Let’s do an experiment by burning several pieces of paper and observing the results. Follow these instructions in the presence of an adult and with extreme caution to ensure personal safety:

  • Gather a few sheets of paper. Weigh it and make a note of how much it weighs.
  • Use a match stick to light these pieces of paper on fire.
  • After the papers have been burned gather all of the ash that has been left behind.
  • Weigh the ash and write it down.

It’s possible that you’ll notice the following changes:

  • When you ignite the pieces of paper on fire, they produce a lot of heat & light.
  • The papers emit smoke and water vapor during the burning process.
  • The papers have decomposed into ash, a new material.
  • In comparison to the initial weight of paper, the ash gathered thereafter is lighter.

For the following reasoning, all of these findings lead to the conclusion that burning paper is a chemical change:

Carbon compounds make up the majority of the paper. When carbon compounds combine with oxygen to produce carbon dioxide and water, it is burned. 

Water and carbon dioxide makes up the majority of the smoke & water vapors emitted. They get disoriented and are unable to be retrieved. There occurs the formation of new material.

The ash that remains cannot be recycled into paper. The transformation is both permanent and irrevocable. On paper, you may write, but not on ash.

The ash generated has characteristics that vary from the original paper. The ash is practically black since it is made primarily of carbon, while the paper was white.

The ash has an amorphous form and size, while the paper was defined by its size and shape.

During the process of burning paper, a considerable quantity of heat and light energy is produced. During the reaction, one may feel the warmth & watch the dazzling flames.

As a result, burning paper results in a chemical change.

Paper’s Applications

Applications of paper are given below:

  • It’s a cleanser for the grill.
  • Packing of breakable or delicate items
  • Deodorant

I will now elaborate on the guidance given above.

It’s a cleanser for the grill.

When you’re done grilling, the grills are normally tough to clean, and it would require a lot of effort. However, if you use a damp newspaper and set it on the grill a few minutes after you finish cooking your barbecue, it will be much easier to clean.

Packing of breakable or delicate items

Paper may be used to prevent easily breakable or delicate goods from being ruined while they are packed. This is usually done while you’re packing your belongings or getting ready to relocate to a new location.


Some of your belongings, such as shoes, might benefit from the use of paper as a deodorant. When you’ve worn your shoe for an entire day and then put it on your shelf, it might smell horrible, but if you put paper in it, it will deodorize it and make it smell normal again.

Frequently Asked Questions(FAQs), “Is paper fire resistant?”

What is the temperature at which paper catches fire?

Although paper ignites at roughly 480 degrees F, it burns at a much higher temperature. A paper fire reaches a temp of 1,500 degrees F, give or take a few hundred degrees. 

The flames themselves are normally between 650 and 800 degrees at their tips.

Is tissue paper flammable?

The temp at which paper burns varies depending on the material, moisture content, and thickness. It will ignite and burn at a temp of 424 to 475 degrees F on average (218 and 246 degrees celsius).

How do you securely burn paper?

If you have a lot of letters, burn them carefully in a stone or metal fire pit. Fire pits will keep the blazing papers contained, allowing you to enjoy a hot fire without endangering the tree branches or grasses in the area. But don’t worry if you don’t have access to a fire pit.

Is it possible for a newspaper to spontaneously combust?

Paper is an enthralling and very useful substance. It has a flashpoint of 480 degrees F, which means it will ignite and burn at this temp or higher. 

Paper can readily catch fire when it comes into touch with sparks or flames since bare flames are considerably hotter than this.

Is it possible for cardboard to catch fire in the sun?

No, since the temperature at which paper self-ignites is roughly 480 degrees Fahrenheit. That’s the temp at which a light substance will ignite if it isn’t touched by a flame. Because cardboard is less combustible than paper, the needed temp may be greater.
