Guide to Choosing the Right Vacuum Bags

Did you know that vacuum bags are the most important factor in quality food storage? If you find that your vacuum bags are melting when you use a vacuum sealer to evacuate them or that the machine is not removing enough air, then the problem is with the vacuum bags you are using, not with the machine as most users believe.

Read the following post for the most important tips when vacuum packing food for freezing and long term storage. 

What are the best vacuum bags for food?

There are three important factors that determine the quality of a vacuum bag.

The material

Thickness of the layer

Ribbing profile

The material

The construction of the vacuum bag is very important as the inside of the bag is in direct contact with the food. The bag manufacturer needs to guarantee that all materials used are food grade and list the temperatures at which the vacuum bags can be safely used (whether the bags are suitable for freezing and cooking by the vacuum low temperature cooking method).

Food vacuum bags are made from PET or PE. Polyethylene (PE) ensures sealing quality. Recent studies have also shown that PE is one of the safest food materials. After six months or more, your food will remain the same as the day it was vacuum packed. Vacuum bags can also be used for freezing and vacuum cooking at low temperatures (up to 12 hours at 70°C, up to 6 hours at 80°C and up to 15 minutes at 100°C).

If you want to protect the quality of your food, use a good quality food vacuum bag.

Thickness

It is important that the food vacuum bags are thick enough as they also protect the food from external mechanical damage. With the right bag, you don't have to worry about food packages rubbing and tearing against each other in the fridge. Be careful when vacuum packing meat with sharp bones. We recommend that you blot the sharp edges with a paper towel before vacuuming.

Ribbed profile

The last two factors that distinguish a good quality vacuum bag from a low quality bag are the shape and height of the ribbed profile. Both are important for efficient evacuation - the removal of air from the bag in many successive cycles of vacuum packed goods.

Let us elaborate: if you try to use a vacuum pump to extract air from two smooth layers of bags, the layers will stick together and the food will not be stored correctly, even before all the air has been removed. The special shape of the channels in the ribbed profiles ensures efficient airflow during the vacuum packing process. The height of the ribbed profiles ensures high quality vacuum storage in many successive vacuum packaging cycles.
