Envelope with 2 rolls 15x600 cm awkward 3 layers per vacuum -vacuum.

Sacchetti for vacuum with nylon exterior to be impenetrable in the air, and internal in food material; A rough side (awkward or with a footprint) to allow an effective air extraction, the thickness of 105 microns guarantees robustness and kept against accidental breaks; The imprint bag, with an additional external layer in polytene, is more? Resistant and impenetrable to humidity, for better conservation in the freezer. Cut and weldable to obtain customized measures; Usable in the refrigerator, freezer, microwave and to heat in a bain -marie. Washable and reusable; Materials suitable for contact with food, for frozen -40 and for cooking up to 100 for 4 hours. The vacuum bags must be resistant, waterproof in the air and suitable for contact with food. The triple stratum bags respond to all these requirements: the interior in polyethylene? suitable for contact with the contained food; The central layer in Polyamide guarantees the holding of the penetration of the air; The external layer, still in polyethylene, makes the bag more resistant to perforation or laceration, safe in case of contact with other foods and, preventing the penetration of humidity, reduces the formation of frost and ice crystals in the freezer. The special footprints (patented system) on the surface favor the leakage of the air and the creation of a real vacuum.
