Vacuum Sealer For Mylar Bags

A vacuum sealer for Mylar bags is an essential tool for long-term food storage, keeping items fresh and protected from moisture, oxygen, and pests. Whether you’re preserving dry foods, emergency supplies, or valuable items, using the right vacuum sealer ensures maximum shelf life.

In this guide, we’ll explore the best vacuum sealers for Mylar bags, their benefits, key features to consider, and tips for effective sealing.

Why Use a Vacuum Sealer for Mylar Bags?

Mylar bags are one of the best materials for food storage because they provide a strong barrier against air, light, and moisture. However, to achieve the best preservation results, a vacuum sealer removes excess oxygen, preventing spoilage and extending food freshness.

Key Benefits of Using a Vacuum Sealer for Mylar Bags

Extends Shelf Life – Removes oxygen, preventing mold, bacteria, and food spoilage.
Preserves Flavor and Nutrients – Keeps food fresh for years.
Protects Against Moisture and Pests – Keeps out insects, rodents, and humidity.
Space-Saving Storage – Compresses food, making storage more efficient.
Ideal for Emergency Preparedness – Keeps food ready for long-term survival situations.

Types of Vacuum Sealers for Mylar Bags

Not all vacuum sealers work well with Mylar bags. Here are the main types:

1. Chamber Vacuum Sealers

Best for heavy-duty food storage.
Works well with thick Mylar bags.
Removes air from both the bag and inside the chamber, ensuring a complete seal.

2. External Vacuum Sealers

Most common and affordable option.
Works best with channel-style vacuum bags but can be used with Mylar bags with an oxygen absorber.
Requires textured Mylar bags or sealing with an impulse heat sealer.

3. Handheld Vacuum Sealers

Portable and easy to use.
Works with zip-lock Mylar bags with a valve.
Less powerful than chamber or external sealers.

How to Choose the Best Vacuum Sealer for Mylar Bags

1. Suction Power

Higher suction power removes more air, ensuring better preservation.
Look for models with at least 20-25 Hg vacuum strength for optimal performance.

2. Compatibility with Mylar Bags

Some standard vacuum sealers don’t seal Mylar bags properly because they lack textured surfaces.
Choose a sealer with an adjustable heat setting or use a separate heat sealer.

3. Sealing Strength

Double-seal function ensures a tight and secure seal.
Adjustable sealing time allows for custom sealing based on bag thickness.

4. Size and Portability

Compact models are ideal for home use, while larger chamber sealers suit bulk storage needs.

5. Additional Features

Moist and Dry Settings – Allows sealing of both dry and moist foods.
Built-in Cutter – Helps customize bag sizes.
Adjustable Temperature – Useful for sealing different thicknesses of Mylar bags.
