Harvest Right 12 Inch Impulse Sealer

Protecting freeze dried food for long term storage requires more than removing moisture from the food itself. Once a batch leaves the freeze dryer, the storage package needs a dependable seal that helps prevent outside air and moisture from getting back inside. The Harvest Right 12 Inch Impulse Sealer is designed for exactly that final step.

With a 12 inch sealing length and heavy duty 5mm wide seal, it creates a substantial closure across compatible Mylar storage bags. Pair it with properly sized Mylar bags and oxygen absorbers to create a complete packaging system for freeze dried foods, emergency food storage, garden harvests, snacks, ingredients, and other preserved products.

• Heavy Duty 5mm Seal: Creates a Wide, Dependable Storage Barrier
• Seals Bags Up to 12 Inches: Handles Multiple Mylar Bag Sizes With Ease
• Adjustable Heat Control: Dial In the Setting for Different Bag Thicknesses
• No Warm Up Required: Ready to Seal as Soon as Your Batch Is Packaged

12 Inch Sealing Capacity

The sealing bar accommodates bags up to 12 inches wide, providing enough capacity for many commonly used Mylar bag sizes.

Its generous sealing length also gives users flexibility when packaging different portion sizes rather than limiting the setup to smaller storage bags.

Heavy Duty 5mm Seal

The sealer produces a 5mm wide seal, creating a broad barrier across the opening of the bag.

For long term storage, seal integrity matters. A strong, consistent closure helps protect properly packaged contents against environmental oxygen and moisture that could otherwise compromise storage quality.

Adjustable Heat Control

Not every Mylar bag has the same material thickness. The adjustable heat dial lets you change the sealing intensity to better match the packaging being used.

Start at a lower setting and gradually increase the heat until the bag develops a clean, secure seal without excessive melting.

This adjustability makes the unit useful for operators who regularly work with different Mylar bag sizes and thicknesses.

No Warm Up Required

Impulse sealing technology means there is no lengthy preheating process before you begin packaging.

The heating element activates during the sealing operation rather than remaining continuously heated, allowing the machine to be ready when you need it.

This is particularly convenient when unloading a freeze dryer and packaging multiple trays of finished product at once.

Built for Repeated Packaging

At approximately 13 lbs, the sealer has a substantial base that provides stability while working with filled bags.

That added stability becomes useful when packaging larger quantities, where lightweight sealing equipment can shift or move while a full Mylar bag is being positioned.

An Essential Part of Long Term Storage

Freeze drying removes moisture from food, but proper packaging is what helps protect that food after the cycle is complete.

A typical long term storage workflow involves placing the freeze dried product into an appropriate Mylar bag, adding the correct oxygen absorber, and then creating a secure seal across the bag opening.

The Harvest Right Impulse Sealer provides the final physical barrier in that process.

Checking Your Seal

After sealing, visually inspect the entire seal line. It should appear continuous and uniform without gaps, wrinkles, or visibly unsealed sections.

A gentle tug test can also help confirm that the two sides of the bag have bonded properly.

For additional security, a second seal can be placed above the first seal when sufficient bag material is available. Avoid repeatedly sealing directly over the same location, as excessive heat can damage the packaging material.

Ideal For

The Harvest Right 12 Inch Impulse Sealer is a practical addition for Harvest Right freeze dryer owners, long term food storage, emergency preparedness supplies, garden and homestead preservation, freeze dried fruits and vegetables, freeze dried meals and ingredients, bulk food packaging, and frequent Mylar bag sealing.

Recommended Use Practices

• Confirm food is completely dry before packaging and sealing.
• Start at a lower heat setting and increase gradually as needed for your bag thickness.
• Add the oxygen absorber immediately before sealing.
• Position the bag opening flat and evenly across the sealing bar.
• Inspect the completed seal line for gaps, wrinkles, or unsealed sections.
• Perform a gentle tug test to confirm the seal has bonded properly.
• Add a second seal above the first when extra security is needed, using a fresh section of bag material.
• Allow the unit to cool between uses if performing many consecutive seals.
