Enhanced barrier vacuum metallized films |
摘要 |
A multi layer film having enhanced barrier properties against transmission of oxygen and water vapor is provided. The multi layer film includes a polypropylene base layer, with a high density polyethylene layer on at least one surface of the polypropylene base layer. The polyethylene layer includes a surface which has been subjected to plasma treatment with a hydroxyl-donating material such as a methanol. The film further includes a metal layer deposited on the plasma treated surface, such as a layer of vacuum deposited aluminum. Multi layer films according to the present invention are particularly useful as packaging films for food products. |
