Universal lid to Vacuum GN Containers

Gastronorm lid to put under vacuum any GN stainless steel containers of the maker. System similar to Greenvac solution

What satisfactory professional solution is there currently on the market to store your vegetables, fruits, cheeses, meats, or other dishes for 2 to 5 days on the refrigerator?
The observation is simple, not much...

Cover your food with cling film: this is the fastest solution, often impractical, especially on large containers, but also the least effective. This is because your food will stay in contact with the oxygen in the air and will oxidize. In addition, there will always be a risk of bacteriological contamination between foods in your fridge.
Vacuum-pack your food or dish in a pouch: this is a very effective solution. If you have a vacuum chamber machine you can even adapt the vacuum precisely according to the food. Unfortunately this method requires a lot of steps, is time consuming and you will have to use a significant amount of pouches. In addition, this solution is unsuitable for foods that should not be compressed.
The Greenvac-type system: this is an excellent way to vacuum food directly into gastronorm containers. The vacuum is of high quality, well controlled and the food is not crushed. Unfortunately this system requires SPECIAL containers and lids. It will take several hundred euros for a full set .... If you do not have a vacuum chamber machine with a specific outlet, you will have to buy an external pump which is also expensive.

What we offer for sale is a fast, efficient, economical vacuum system allowing you to use ALL gastronorm stainless steel containers available on the market and especially those you already use in your kitchen. The purchase of the portable cordless pump is necessary for the use of this system.
