| Detailed Product Description: | The concept is to vacuum wooden packaging goods into the box, out of the air inside the box, after reaching a predetermined degree of vacuum sealing process is completed. Vacuum inflatable packaging articles into the box, out of the air inside the box after a predetermined degree of vacuum, and then filled with nitrogen or other gas mixture, and then complete the sealing process. So that the box reaches a certain vacuum. Wooden vacuum vacuum vacuum wooden wooden packaging material has been able to reach the vacuum state, depending on the kind of wooden packaging materials used in the interior, the current vacuum inside wooden packing material used is aluminum, in addition to anti-oxygen through good shrinkage properties and polyvinylidene ethylene dichloride (PVDC), there are polyester, polyamide; or nylon, polyester and polyethylene multilayer film and other materials. Polyvinylidene chloride, ethylene which prevents oxygen and water vapor permeability of the membrane material for a variety of crown, but the biggest drawback is not heat-sealed. Polyester has a strong tensile strength, soft; nylon prevents oxygen transmission rate is still good, heat, cold also good mechanical properties are also very strong, but the water vapor transmission rate is large, and expensive, so much so as to in the form of a multi-layer composite wooden vacuum packaging materials. |
