archival storage of paper products  -  polyester film uses
The archival storage of those precious items we work hard is often overlooked.
Imagine buying a long-sought
After the comics (
Under mint conditions)
After reading it, you put it up to make sure it's safe.
A year later, you dig it out and appreciate it and find that it is not the same shape as when you put it up.
The former white pages are now yellow and brown.
You start crying.
Even though we use computers a lot today, we all have items or collectibles that we want to keep safe for a lifetime.
Some are collectible items (
Stamps, comic books, magazines, postcards, sports cards, etc. )
While others are very personal items, and while we may put them on the computer, we want to be able to feel and smell history (
Photos, books, greeting cards, etc. ).
Among these products, paper products are the most vulnerable.
Proper storage of these items must be considered, especially if you plan to keep them in any time.
Sunlight, rodents, moisture, insects and mold are just a few enemies of paper.
This helps to understand how the paper is made and how it goes bad.
Let's start.
A lot of paper in the paper making process starts with trees used on raw materials, but many types of fiber plants can be used (
Cotton, bamboo, rice, straw, marijuana, etc. ).
Cotton is used to make high-quality paper, which is used in the United States. S. currency.
Despite the high quality of the paper, most of the paper is made of trees and of lower quality.
The fibers found in the paper must be reduced to pulp first, and there are two basic varieties: grinding wood and chemical Wood.
Grinding wood is basically made by mechanically grinding logs to separate the fibers.
This is a very cheap and efficient method, so it is widely used in news paper, comic books and paperbacks.
Because this pulp is made of all wood fiber, the paper is not made of pure cellulose.
Exposed to the Sun, the ground pulp turns yellow or brown.
Chemical pulp uses heat and chemicals to release more cellulose fibers that produce 40-50% of raw wood.
Used in more expensive paper (
Stationery, hardcover books, etc. ).
Then press the pulp into thin sheets.
In today's paper-making process, bleach and other chemicals are heavily used and will not last on paper centuries ago.
The main reasons for the deterioration of paper products are oxidation and acid hydrolysis. Oxidation (
Combined with oxygen in the air)
Destroy cellulose, resulting in increased acidity and dimming.
Oxygen and UV rays also cause the paper to turn yellow and some ink to fade.
As acid hydrolysis involves heat and acid, the paper becomes brown and fragile.
When they get to this extreme, it crashes even by touching the paper.
The sources of acids can include oxidation reactions, chemicals used for paper making, and even the fibers themselves.
Some of the paper today is acid free, but most of the paper collections do contain acid and need help to extend the life of the paper.
Archive storage guidelines try to keep paper products cool, dark and dry.
It is very important to avoid light, heat and moisture.
Make sure your hands are clean and even use white cotton gloves if you handle paper products.
Aim at the relative humidity of 35% as much as possible and the temperature is less than 72 degrees (
According to the Library of Congress).
Storage Materials (
Envelopes, sleeves, boxes, etc. )
Quality of files.
The Mylar D type produced by DuPont is a polyester film that is resistant to moisture, oil and acid and is more durable than most other plastics. The U. S.
The Library of Congress says the first material to keep valuable documents is a movie like Mela.
Don't store your paper souvenirs in regular cartons, they are acidic and will speed up deterioration.
For proper storage, please use the back panel and box that meet US standardsS.
Minimum government requirements.
They have a minimum pH of 8.
5 and the buffer has alkaline reserves throughout the process.
Be careful when buying products that are "acid-free when made" because they are usually just coated with alkaline substances on the surface.
This will wear out soon.
De-acid before File storage is a process in which spray is used to soak paper with alkaline reserve, thereby neutralising existing acid and preventing further decay.
It is best to leave the process to professionals.
File storage fire protection solutions fire safety deposit boxes and filing cabinets are easier to buy today and more expensive than before.
One thing that people ignore is whether the safe is waterproof.
In a fire, there will be firefighters who will inject quite a lot of water into your house or building.
Water destroys paper collectibles, photos, or souvenirs.
Many people don't realize that water hurts paper as much as fire.
The safe they make is fire and waterproof.
Another option is to put your item in the bank's safe.
If you search for "archive storage supplies" on Google, you will get a few pages of valuable resources.
When we begin to realize how fragile the paper is, they are more readily available today.
Do your research well because some companies are trying to cheat you with clever wording.
They are trying to convince you that their product has the quality of archival storage.
The higher your quality, the higher the cost.
You have to decide how important each project is to you.
Going this extreme on all your paper products may not be practical or realistic, but I hope you will be able to use some of these tips to protect even a very small layer.
Don't forget to meet with your insurance agent and adjust your coverage for any collection.
If you have recently purchased a high-priced paper collection, you may have to increase your coverage.
