NatureVac’s honeycomb vacuum power technology allows you to seal in a variety of foods, including meats, herbs, seafood, fruits, vegetables, grains, pasta, lentils, cheese, coffee, leftovers, and more. This new material is thicker and stronger for ultimate durability and blocks out harmful light, optimizing product visibility. In addition, NatureVac locks out moisture and air to reduce freezer burn and seal in freshness. These rolls are compatible with NatureVac brand sealers and most other brands.
