Introduction
Is newspaper acid free paper? This is a very common question. Many people notice that old newspapers turn yellow and brittle very quickly. Furthermore, this happens much faster than with other types of paper. So why does newspaper deteriorate so fast? Moreover, what is acid free paper and why does it matter? In this article, we answer the question — is newspaper acid free paper — in a clear and simple way. Furthermore, we explain everything you need to know about acid free paper and how it compares to regular newsprint. So let us get started!
Is Newspaper Acid Free Paper? The Short Answer
Is Newspaper Acid Free Paper — Direct Answer
No. Newspaper is not acid free paper. Furthermore, newspaper is actually one of the most acidic types of paper available. It is made from cheap unrefined wood pulp. Moreover, this wood pulp contains a substance called lignin. Lignin makes the paper highly acidic. As a result, newspapers yellow and become brittle very quickly compared to other types of paper.
Is Newspaper Acid Free Paper — What the Experts Say
Paper experts and scientists agree that newspaper is acidic paper. Newspaper has a low pH level which makes it acidic. Carefully stored newspaper can have a life expectancy of up to 20 years. However, left exposed to light and air, it may last only a few weeks. Furthermore, this is a very short lifespan compared to acid free paper. As a result, newspaper is considered one of the least durable types of paper in existence.
What is Acid Free Paper? A Simple Explanation
Is Newspaper Acid Free Paper — Understanding pH Levels
Before we go deeper into the question of is newspaper acid free paper, we need to understand what acid free means. Acid free paper is a type of paper that has a neutral or basic pH of 7 or slightly higher. Furthermore, pH is a scale from 0 to 14. Anything below 7 is acidic. Anything above 7 is alkaline or basic. As a result, acid free paper sits at 7 or above on the pH scale.
Newspaper, on the other hand, has a pH well below 7. Furthermore, this makes it highly acidic. As a result, it breaks down much faster than acid free paper.
Is Newspaper Acid Free Paper — How Acid Free Paper is Made
Acid free paper is paper that, if infused in water, yields a neutral or basic pH of 7 or slightly greater. It can be made from any cellulose fiber as long as the active acid pulp is eliminated during processing. It is also lignin and sulfur free. Furthermore, during production, acid free paper is treated with a mild base. This is usually calcium or magnesium bicarbonate. Moreover, this treatment neutralizes the natural acids in the wood pulp. As a result, the paper becomes stable and long lasting.
Why is Newspaper Not Acid Free Paper?
Is Newspaper Acid Free Paper — The Role of Lignin
The main reason newspaper is not acid free paper is lignin. Standard paper made from wood pulp is usually acidic, and becomes increasingly so the older it gets. The natural deterioration of lignin — a natural part of plant cells in paper — causes the paper to become acidic and break down. Furthermore, newsprint uses the cheapest and least refined wood pulp available. Moreover, very little lignin is removed during the production of newsprint. As a result, newspaper starts breaking down almost immediately after it is made.
Is Newspaper Acid Free Paper — The Chemical Process
A chemical compound within wood called lignin, mixed with the bleach from the refining process, will turn to hydrochloric acid as the paper ages. The acid will break down the chemical compounds within the paper, resulting in what is commonly seen as yellow and brittle newspaper clippings. Furthermore, this chemical process speeds up when newspaper is exposed to light and heat. Moreover, even normal indoor lighting can speed up the yellowing process. As a result, old newspapers are a perfect example of what acidic paper does over time.
Is Newspaper Acid Free Paper — Cost vs Quality
Newspaper is not acid free paper because of cost. Furthermore, making acid free paper is more expensive than making regular newsprint. Newspaper companies need to print millions of copies every day. Moreover, they need to do this at a very low cost. As a result, they use the cheapest wood pulp available — which happens to be highly acidic.
How Long Does Newspaper Last Compared to Acid Free Paper?
Is Newspaper Acid Free Paper — Lifespan Comparison
This is one of the most important aspects of the question — is newspaper acid free paper. The difference in lifespan between newspaper and acid free paper is enormous. Here is a simple comparison:
| Paper Type | pH Level | Lifespan |
|---|---|---|
| Newspaper (Newsprint) | Below 7 (Acidic) | 20 years stored / weeks if exposed |
| Regular Office Paper | Around 7 (Neutral) | 50 to 100 years |
| Acid Free Paper | 7 or above (Alkaline) | 200 to 500 years |
| Archival Acid Free Paper | 7.5 or above | 500 to 1000+ years |
Furthermore, this table makes it very clear. Newspaper lasts only a fraction of the time that acid free paper does. Moreover, acid free archival paper can last over 1000 years under the right conditions. As a result, the choice of paper makes a huge difference for anything you want to preserve long term.
What Happens to Newspaper Over Time?
Is Newspaper Acid Free Paper — The Yellowing Process
Everyone has seen old yellow newspapers. But why does this happen? Is newspaper acid free paper — the answer to this question explains the yellowing perfectly. When newspaper is exposed to light, heat, and air, the lignin in the paper reacts chemically. Furthermore, this reaction produces acid. Moreover, the acid breaks down the paper fibers. As a result, the paper turns yellow and eventually becomes brittle and crumbly.
Is Newspaper Acid Free Paper — Speed of Deterioration
The deterioration of newspaper is surprisingly fast. Furthermore, a newspaper left outside in sunlight can show visible yellowing in just a few hours. Moreover, even stored indoors, a newspaper will show significant yellowing within a few years. As a result, newspaper is considered completely unsuitable for any long term storage or preservation purposes.
Is Newspaper Acid Free Paper — Can You Slow Down the Decay?
Yes. You can slow down the decay of newspaper. However, you cannot stop it completely. Here are some tips:
- Store newspapers away from direct light and heat
- Keep them in a cool and dry environment
- Place them in acid free storage boxes or folders
- Avoid storing them near other acidic materials
- Scan or digitize important newspaper clippings
Furthermore, even with careful storage, newspaper will still deteriorate over time. As a result, the only truly effective solution is to transfer important newspaper content to acid free paper or digital formats.
