The normal bags aren’t efficent for the elimination of the air stagnation in the bag because they do not have a “barrier” allowing to keep the vacuum in the bag: this can cause a fast food deterioration.
The bags Besser Vacuum are made with a special film PA/PE suitable for the food preservation under vacuum and they are available in the smooth or embossed version, and in different sizes.
Both bags are made with the same material (PA/PE) but with different thicknesses. The smooth bag is available in various grammages (70, 90 and 140 my), while the embossed bag is available in 90 my.
The main difference concerns the utilization type: the smooth bag is suitable for chamber vacuum packaging machines while the embossed one must be used with external suction machines. In the chamber machine, when desiring an external vacuum (the bag is put exteriorly to the chamber) it is recommended to use an embossed bag because the special embossing allows to extract the air from the bag. It is necessary to follow these recommendations in order to have an optimal vacuum.
Besser Vacuum doesn’t recommend the re-use of the bags because there may be food residuals or humidity in the bag. This is negative on both the hygienic and vacuum quality point of view.
If the bag is perfectly clean and without residuals, it can be reused.
The normal vacuum bags aren’t suitable to reach high temperatures. For all the cooking and heating needs you can use the special cooking vacuum bags Besser Vacuum, that can reach 115°C and are suitable for the cooking in the microwave, with vapour and in bain-marie.
It’s very important to be sure that the bags that are beign used are suitable for the heating and that you are respecting the recommended temperature limits; otherwise there may be the risk that some substances contained in the bag migrate into the food.
You can choose the type of bag according to these parameters:
Medium Barrier Bags For fruits, vegetables and salads (raw)
High Barrier Bags For meat, etc.
Cooking Bags If you cook Sous Vide or want to cook or heat using the bags.

Normal bags are not effective in eliminating stagnant air inside, since that do not have a barrier that keeps the emptiness in the bag, this can lead to a rapid deterioration of food.
