Tyhjiöpusseja

Tyhjiöpusseja, known in English as vacuum bags or food saver bags, are specialized plastic bags designed for use with vacuum sealing machines. These bags are constructed from materials that are impermeable to air and moisture, creating a barrier that prevents oxidation and spoilage of food products. The primary function of a tyhjiöpussi is to remove air from the packaging before sealing it, thereby extending the shelf life of the contents.

The vacuum sealing process, which utilizes these bags, removes most of the air surrounding the food. This reduction in oxygen significantly slows down the processes that lead to food degradation, such as bacterial growth, enzymatic activity, and moisture loss. Consequently, food stored in tyhjiöpusseja can remain fresh for considerably longer periods compared to traditional storage methods like plastic wrap or standard containers.

Tyhjiöpusseja are commonly used in both domestic and commercial settings for a variety of food items, including meats, cheeses, vegetables, and dry goods. They are particularly effective for freezing, as the absence of air minimizes freezer burn. Beyond food preservation, these bags can also be employed for non-food items, such as protecting documents or clothing from moisture and pests. The bags are typically made from multi-layered plastics, often including a layer of nylon to provide a barrier against oxygen.
