Freshness Locked In: Vacuum Bags, Barrier Bags, and Vacuum Sealers

When it comes to keeping food fresher for longer, few tools are as effective as vacuum sealing or barrier bags. At Durapak Supply, you’ll find not only a wide selection of food-safe vacuum and barrier bags, but also reliable vacuum sealers designed to work seamlessly with them. Together, they form a powerful solution for preserving taste, texture, and shelf life—whether you’re a restaurant, butcher, food processor, or simply someone who wants to store bulk groceries at home.

What Are Vacuum and Barrier Bags?

• Vacuum Bags are specially designed pouches that allow air to be removed before sealing. By extracting oxygen, they reduce oxidation, bacterial growth, freezer burn, and spoilage. This dramatically extends shelf life and locks in freshness.

1. 3 Mil Poly Nylon Vacuum Bags – durable, transparent bags used with chamber vacuum sealers or commercial vacuum sealer with nozzle for commercial or professional cooks.
2. Channel Vacuum Bags – Perfect for home use, these textured vacuum bags have a special embossed surface, creating channels for air to easily be removed from the bag. They work with inexpensive plug and play Food Saver kind of vacuum sealer which can be easily purchased at Costco Wholesale or online.
3. Poly Nylon Zipper Reclosable Lock Vacuum Moisture Barrier Bags – Multi layers, polyethylene for secure sealing and nylon for moisture barrier and air-tight packaging. Work with vacuum sealers with nozzle or chamber vacuum sealer.

• Barrier Bags are zip reclosable and do not need a vacuum sealer. Constructed with multiple layers—often polyethylene, nylon, or foil, kraft—they block moisture, oxygen, light, and even odors from entering. Common Foods Packaged in Barrier Bags:

1. Snacks: Potato chips, popcorn, and cookies
2. Dry Goods: Coffee beans, tea, spices, nuts, dried fruit, and flour
3. Meats and Seafood: Fresh and processed meats, including jerky
4. Dairy & Frozen Foods: Ice cream, frozen items, and cheese blocks
5. Liquids & Sauces: Juices, sodas, sauces, and powders
6. Other: Candy, pastries, baby food, and ready-to-eat meals

Key Features to Look For

• Multi-Layer Construction: Polyethylene for sealing strength, nylon for puncture resistance and oxygen barrier, optional foil/PET for blocking light and aroma.
• Puncture Resistance: Essential for sharp foods like meat with bones or seafood with shells.
• Strong Seals: Heat-sealed seams prevent leaks and air intrusion.
• Thickness Options: Heavier gauge bags offer more protection for long-term storage.
• Food Safety: All materials must be safe for direct food contact.

Durapak’s lineup includes poly-nylon vacuum, channel vacuum bags, food barrier bags for everyday storage, as well as zip-reclosable barrier bags for moisture and aroma-sensitive foods.

Introducing Durapak’s Vacuum Sealers

Of course, bags are only half the solution— for vacuum bags you need the right machine to make them work.

Durapak offers 5 options:

1. Vacuum Sealer with Nozzle / Single Jaw
2. Vacuum Sealer with Gas Purge
3. Vacuum Sealer with Gas Purge and Dual Nozzles. All above 3 options need outside air pumper to work with. They are more efficient, higher speed solution than following self-contained vacuum sealer.
4. Chamber vacuum sealer. Plug and play, easy to use. Air pump built in, no need outside air pump.
5. Self-contained vacuum sealer with a built-in air pump, meaning you don’t need an external compressor. This plug-and-play design makes it simple to set up and operate, even in busy kitchens or production environments.

• All-in-One System: Internal air pump—no external equipment required.
• Compact and Portable: Space-saving design, perfect for small businesses or limited counter space.
• Easy Operation: Just plug in, load the bag, and seal—ideal for batch packaging.

This makes Durapak’s vacuum sealers an excellent match for their range of barrier and vacuum bags, ensuring consistency and reliability with every seal.

Benefits of Pairing Vacuum Bags with the Right Sealer

When you combine Durapak’s vacuum sealer with their vacuum bags, you get a complete system designed to maximize preservation:

• Longer Shelf Life: Foods stay fresher, flavors last longer, and freezer burn is minimized.
• Reduced Waste: Prevent spoilage and leaks, saving money in the long run.
• Professional Presentation: Clear, tight-sealed packaging looks clean and appealing.
• Versatility: Works for fresh meats, cheeses, dry goods, coffee, prepared meals, or sous-vide cooking.

Best Practices for Use

• Leave a little headspace in bags before sealing, especially when freezing.
• For sharp items, wrap edges to prevent punctures.
• Label bags with content and date for better rotation.
• Use barrier bags for light- or odor-sensitive products.
