What is Mylar Encapsulation?
Mylar encapsulation, also known as polyester encapsulation, is a preservation technique. It seals your documents, photos, or other flat items within two layers of clear film. The film is often referred to as Mylar, a brand name that has become synonymous with the material. This creates a protective barrier against dust, dirt, moisture, pollutants, and even the oils from your skin. All of these elements can contribute to deterioration of soft materials over time. Think of it as creating a mini time capsule for your treasured items.
Why Choose Mylar Encapsulation?
You may be wondering, “Why Mylar encapsulation over other preservation methods?” The answer lies in its unique combination of benefits:
- Superior Protection
Mylar is incredibly strong and durable, providing a robust shield against physical damage. It’s also chemically inert, meaning it won’t react with your items causing further deterioration. This is crucial for preserving delicate or aged items. - Long-Term Preservation
When done correctly, Mylar encapsulation can extend the lifespan of your documents and photos. This will help ensure they remain in good condition for years to come. It’s a proactive way to protect your legacy. - Enhanced Appearance
The clear Mylar enhances the look of your items, making colors more vibrant and text more legible. It provides a professional, finished look while allowing the item to be fully visible. - Reversibility
Unlike lamination, Mylar encapsulation is completely reversible. If you ever need to access the document or photo, the Mylar can be removed without causing damage. This is a critical advantage for archival purposes. - Ease of Use
Mylar encapsulation is a relatively simple process you can do with the proper know-how and the right supplies. This makes it an accessible and cost-effective option for preserving your personal collections.
What Can You Encapsulate?
The versatility of Mylar encapsulation makes it suitable for a wide range of flat items. This includes:
- Important Documents
Preserve birth certificates, marriage licenses, diplomas, and other essential records. - Letters and Correspondence
Safeguard sentimental letters, postcards, and other personal correspondence. - Photographs
Protect your precious family photos from fading, scratches, and water damage. - Artwork on Paper
Preserve drawings, prints, and other artwork on paper. - Collectibles

How to Encapsulate Items Yourself
Professional encapsulation services are highly recommended for the best possible preservation. However, you can also try to encapsulate your items at home using the instructions below.
Mylar Encapsulation Supplies
- Mylar Sheeting
Choose a high-quality, archival-grade polyester film specifically designed for encapsulation. It’s available in rolls or pre-cut sheets. - Heat-Activated or Ultrasonic Welding
This is the method of sealing the Mylar film. Heat-activated involves using a tacking iron or heat press. Ultrasonic welding uses sound waves to create a seal. - Release Paper
This special paper prevents the Mylar from sticking to your items during the sealing process. - Scissors or Rotary Cutter
Sturdy enough for cutting or trimming the Mylar plastic film. - Ruler or Measuring Tape
For accurate measurements of your documents, photos, and Mylar film. - A Clean, Flat Surface
A spotless, level workspace is essential to prevent debris from getting into the sealing process.

The Sealing Process (Heat-Activated)
- Prepare Your Items
Ensure your items are clean and free of dust or debris. Handle them with care, ideally wearing cotton gloves to avoid transferring oils. - Cut the Mylar
Cut two pieces of Mylar sheeting slightly larger than your item, allowing for a border around all sides. - Position Your Item
Place your item on one sheet of release paper, then center it on one of the Mylar sheets. Cover with the second sheet of release paper, then the second sheet of Mylar. - Seal the Edges
Set to the appropriate temperature on your tacking iron. Then, carefully seal the edges of the Mylar, working your way around the item. Be sure to leave a small border. - Trim the Excess
Once sealed, trim any excess Mylar around the edges for a neat finish.

Tips for Success
- Practice Makes Perfect
If you’re new to encapsulation, practice on some less important items first to get the hang of the process. - Work in a Clean Environment
A clean workspace is crucial to prevent dust and debris from getting trapped in the encapsulation. - Only Use Archival-Quality Materials
Ensure all your supplies, including the Mylar, release paper, and tape, are archival-quality and acid-free. - Handle Items with Care
Always handle your delicate documents and photos with care, ideally wearing cotton gloves. - Store Properly
Even after encapsulation, it’s important to store your items in a cool, dry place away from direct sunlight.

Decorative matting rests on top keeping the item away from the frame’s edges. This is usually where acids and moister creep in through the wood over time. Matting is also important for the item to breath. In addition, it isolates the item and gives the viewer’s eye space to move into the centerpiece. Finally, choosing textured matting gives the frame design a richer look that can’t be achieved with paper matting alone.
