We build a custom time capsule based on your specifications.
Time Capsule Manufacturer – Time Capsules, Inc.

Time Capsules, Inc. will custom build a time capsule to protect your items from the effects of time. We build a custom time capsule based on your specifications using a controlled environment to protect and preserve virtually any material for centuries.

There’s no telling who may be reading over our shoulders 500 years from now. That’s why contemporary documents and memorabilia that are to be passed on to future generations deserve very special attention. Time Capsules, Inc. will custom build a time capsule especially for you to protect your items from the effects of time. The capsule is extraordinary!

500 Years of Integrity with Our Time Capsule. We Promise. The capsules we design are more than just a container to protect your materials from the effects of time. Each capsule is constructed to withstand humid and/or slat laden atmospheres or urban atmospheres containing sulphur dioxide or corrosive pollutants. The capsule also withstands the pressure extremes to which it is subject during the atmosphere exchange cycle.

Our patented Vapor Phase Deacidification process is what has our time capsules go beyond extraordinary. This process chemically treats the contents with a mild organic alkaline substance which neutralizes the acidity of paper and renders its life expectancy 25 to 40 times greater than untreated paper. No one else can deliver that kind of effectiveness. That’s why our capsules are guaranteed for 500 years.

How our Time Capsule Works

Capsule Preparation

When ready to use, a predetermined amount of Hexamethylenetetramine (HMT) – a mild organic alkaline – is weighed into a fine mesh cotton sack and sealed in the capsule with the items to be preserved.

Vapor Phase Deacidification

When the oxygen is later evacuated and replaced with dry argon gas, the HMT slowly transforms from its solid state into a gas which permeates the contents. The HMT vapor neutralizes the acidity of the paper and extends its life expectancy from 25 to 40 times that of untreated paper. This process is called Vapor Phase Deacidification, and it’s the key to the time capsule’s preserving capability. This chemical process is patented in the U.S. and in four foreign countries


Sealing is accomplished via a special Viton rubber gasketing material and an inert silicone “grease” around the perimeter of the portal. The access cover of both the inner capsule and the out container (if used) are held in place by 1/4″ X 20″ stainless steel hex-head cap screws on approximately 2″ centers around the sealing periphery. When sealed, the capsule is air and liquid tight.

Air Replacement

After sealing, a quick connect manifold withdraws the air by a vacuum pump. The air is then replaced by the argon gas to eliminate the effects of oxygen on the contents.
Deterioration and How Our Time Capsule Technology Protects Against It

We have developed a technology to preserve books, documents, metals, plastics and archival materials of almost any type for as long as the capsule itself lasts. For many years researchers have sought answers to the causes of deterioration of book paper, documents and other cellulose containing archival materials.

Fiber Degradation

Molecule Oxidation

UV Degradation

Fungus Attack

Insect Infestation

Bacterial Attack

The time capsule is unique.

Custom built to your specifications, with a controlled environment to protect and preserve virtually any material for centuries. The construction of the capsule enables us to guarantee it for 500 years against flood damage (fire proof also available) should such natural disasters occur where the capsule is stored.

Individual communities, church and civic organizations, museums, and businesses now have a thoroughly tested, scientifically proven way to safely store vital records and artifacts for the future. Regardless of who may be joining our future generations in discovering what made man tick in the 21st century, Time Capsules, Inc. can make you a part of history.
