Mylar envelopes, also known as Mylar bags, have become a staple in various industries due to their exceptional durability and protective qualities. Originally developed by DuPont, Mylar is a type of stretched polyester film that offers high tensile strength and chemical stability. These properties make Mylar envelopes an ideal choice for preserving, storing, and protecting a wide range of items.
Why Choose Mylar Envelopes?
1. Superior Protection
Mylar envelopes provide an unparalleled level of protection against moisture, light, and air, which are common culprits in the degradation of stored items. This makes them perfect for preserving documents, photographs, electronics, and even food products.
2. Durability and Strength
The polyester material used in Mylar envelopes is exceptionally strong and tear-resistant. This durability ensures that the contents remain safe from physical damage during storage and transport.
3. Versatility in Use
From archival storage to emergency preparedness, Mylar envelopes are versatile tools. They are used in various fields including food storage, pharmaceuticals, electronics, and document preservation. Their adaptability makes them a valuable asset in both personal and professional settings.
How to Properly Use Mylar Envelopes for Storage
Step-by-Step Guide
Select the Right Size : Choose a Mylar envelope that fits the items you plan to store. The envelope should be large enough to accommodate the contents without excessive folding or cramming.
Prepare the Items : For food storage, ensure that the items are dry and free from any moisture. For documents or electronics, ensure they are clean and dry.
Insert Oxygen Absorbers (for Food) : Place an appropriate number of oxygen absorbers inside the Mylar envelope to remove residual oxygen and extend the shelf life of the food.
Seal the Envelope : Use a heat sealer to seal the open end of the Mylar envelope. Ensure that the seal is airtight to prevent air and moisture from entering.
Label the Envelope : Clearly label the envelope with the contents and the date of storage. This helps in easy identification and inventory management.
Store in a Cool, Dry Place : Store the sealed Mylar envelopes in a cool, dry place away from direct sunlight to maximize their protective benefits.

Frequently Asked Questions About Mylar Envelopes
1. What are Mylar Envelopes Made Of?
Mylar envelopes are made from BoPET (Biaxially-oriented polyethylene terephthalate), a type of polyester film that has been stretched to enhance its strength and stability. This material is renowned for its barrier properties, which protect against oxygen, moisture, and light. Often, Mylar envelopes are also laminated with other materials to enhance their protective qualities.
2. How Do Mylar Envelopes Preserve Food?
Mylar envelopes are highly effective for long-term food storage. Their excellent barrier properties prevent oxygen, moisture, and light from penetrating the envelope, which can spoil food. When used in combination with oxygen absorbers, Mylar envelopes create an environment that extends the shelf life of dry goods like grains, beans, and dehydrated foods. By reducing the presence of oxygen, they inhibit the growth of aerobic bacteria and fungi, thereby keeping the food safe and fresh for years.
3. Can Mylar Envelopes Be Recycled?
Recycling Mylar envelopes can be a bit challenging due to their composite material structure. While the polyester film itself is recyclable, the process of recycling can be complicated if the envelopes are laminated with other materials or contain residues. Some specialized recycling programs do accept Mylar products, but it is important to check local recycling guidelines. Alternatively, reusing Mylar envelopes for other storage purposes can be an eco-friendly option.
4. How Are Mylar Envelopes Used in Document Preservation?
Mylar envelopes are widely used in archival settings for document preservation. They protect against the detrimental effects of humidity, light, and pollutants, which can cause paper to deteriorate over time. Additionally, Mylar envelopes are acid-free, which means they do not contribute to the acidification of paper, a common problem with traditional plastic or paper storage solutions. They are often used to store photographs, important documents, and archival materials that require long-term preservation.
5. Are Mylar Envelopes Safe for Storing Electronics?
Yes, Mylar envelopes are safe and highly effective for storing electronics. Their excellent barrier properties protect sensitive electronic components from moisture, static electricity, and dust. Many Mylar envelopes designed for electronics storage also include an anti-static layer, which further safeguards against electrostatic discharge that can damage electronic circuits.
