Embodiment 1
[0030] A packaging film for a deoxidizer. The packaging film comprises oil-resistant and waterproof paper, and the opposite sides of the oil-resistant and waterproof paper are covered with a layer of perforated PE film and perforated PET film respectively.
[0031] The thickness of the perforated PE film in this embodiment is 25-50 μm, and the thickness of the perforated PET film is 10-15 μm.
[0032] The hole pitch of the perforated PE film in this embodiment is 0.1-2.5 mm.
[0033] This embodiment also provides a method for preparing a deoxidizer packaging film, comprising the following steps:
[0034] Step 1. Glue the oil-resistant and waterproof paper with a gluing mesh roller, dry it in an oven, and bond it to the PE film. Then corona treat the exposed surface of the PE film, and put it in a drying room for 24-48 hours. Made into semi-finished product I; corona treatment process: speed 100m / min, power 4200KW, test corona value> 38 dynes.
[0035] Step 2. Add a needle ro...
