Two kinds of vacuum bags are available on the market: standard or Vacuum Channel Bags. Vacuum channeled bags are manufactured for machines without chambers. The surface of these bags is embossed in a way that makes channels for the air to come straight out of the bag.
Channel vacuum pouches make it almost impossible for oxygen to get into the bags. Using a vacuum bag will make your food last much longer and keep its flavor. It will also prevent freezer burn and dehydration loss so that you won’t waste any food.
Any vacuum sealer on the market will keep essential nutrients in the taste. But these bags are robust enough to withstand being punctured thanks to their multi layer design, and they can even be heated in the microwave.
These vacuum packaging bags extend the shelf life of food products, forming an airtight seal, and protecting against moisture and bacteria. Vacuum packaging with vacuum pouches also provides a clean, uniform, and professional appearance.
Important factors in choosing a Vacuum Channel Bag:
Three factors are important for determining the quality of vacuum channel bags:
- Materials of Vacuum Channel Bag
- Thickness of Vacuum Channel Bag
- Textured layer design of Vacuum Channel Bag
Materials of Vacuum Channel Bag:
Bag impermeability and seal quality are directly related to the nature of the bags’ materials.
Bag’s material is very important, because they are in direct contact with food. They are made of multi layers of poly amide and polyethylene. Poly amide (PA) ensures oxygen impermeability and polyethylene (PE) ensures quality sealing.
Thickness of Vacuum Channel Bag:
It is very important that food vacuum bags are thick enough, because they also protect the food from outside mechanical damages. Bag thicknesses are measured in Mil, 1 Mil is 1/1000th of an inch. That is not the same as 1 millimeter.
Vacuum sealer bags usually have two separate thicknesses, a smooth side (front) and a textured side (back). The back is almost always thicker than the front. Bags generally have a thickness between 3 Mil and 5 Mil on the front, Most Vacuum Sealer Bags have a back that’s 9 Mil or 10 Mil in thickness.
Thicker Bags are preferable over thinner bags. The textured side of most vacuum sealer bags is often thicker than the smooth side.
Textured layer design of Vacuum Channel Bag:
The last factor that distinguishes top quality vacuum bags from lower quality bags are the shape of the ribbed profile.
The thicker side of a vacuum sealer bag is textured; the texture is created by hundreds of microscopic one-way air valves that allow air to escape but not get back in.
If you would try to pull out the air of the bag with two smooth layers, the layers would stick together even before all the air was removed and the food wouldn’t be stored properly.
The special shape of the channels in the ribbed profile ensures effective air flow during vacuum packing.
Features of Vacuum Channel Bag:
Vacuum channel bags are being made using a multi layer film. The combination of several layers of different materials improves the mechanical and physical properties of the film, including puncture, tear, and heat resistance, as well as moisture and oxygen barrier properties.
- Suitable for home vacuum sealers
- A clear multi layer barrier film
- Easier removal of air from the package
- Preventing the oxidation and discoloration of foods
- Extending the shelf life of products and preserving the food taste
- Reducing freezer burns of the refrigerated food products
- Possibility of printing on the packaging
- Easy storage and transportation
Applications of Vacuum Channel Bag:
These bags are used for long-term food storage in a vacuum. Since they create a stronger vacuum compared to traditional vacuum bags, they have the following advantages:
- Extend the shelf life.
- Better preservation of taste and color of food products
- Reduce the incidence of freezer burn and moisture loss.
- Store dry foods for long periods.
- Prevent moisture from entering the packaging
- Prevent moisture loss from food
Foods You Should Never Vacuum:
A vacuum channel bag is capable of extending the shelf life of all kinds of dry goods, including cereals and grains, milled products, coffee, spices, nuts and beans; but it is not appropriate for some of food; For example:
- Soft Cheeses
- Raw Onions and Garlic
- Raw Mushrooms
- Raw Bananas
- Whole Apples
Advantages of a Vacuum Channel Bag:
Using a vacuum channel bag has many advantages for you that we mention some of them:
- Protect from Freezer Burn. Vacuum sealing foods protects them from freezer burn and dehydration.
- Fresher Food for Longer
- Year-Round Freshness
- Increase Cabinet Space
- Improve Taste, Marinating
- Save Money on Bulk or family packs
- Reduce Waste
- No Chemical Preservation
How to use a Vacuum Channel Bag:
Channeled vacuum bags are commonly used with home use nozzle vacuum sealers to obtain a full vacuum on less powerful machines. The nozzle vacuums the air around the contents, vacuum-packing it.
For using Vacuum Channel Bag First fill the bag with the food you want to seal then start vacuum sealing with your vacuum machine.
