The invention relates to a preparation method for lamination blocking type
package materials, which comprises the steps that: a laminated film is extruded at least one side surface of a support layer base material, simultaneously, the surface treatment is carried out on the laminated support layer base material, blocking type
coating liquid is coated onto the surface of the laminated film, a
blocking layer is prepared through baking, a composite hot sealing layer is extruded on the outer surface of the prepared
blocking layer, a light shading layer is compounded on one side surface of the support layer base material, in addition, the
surface tension reaches higher than 38 dynes through pretreatment, in addition, printing layer
coating liquid is coated on the outer side surface of the light shading layer, a printing layer is obtained after baking, and a
protection layer is extruded on the outer side surface of the printing layer, so the printing layer and the
protection layer are compounded. The light shading layer and the printing layer are compounded on the support layer, the requirement on paper boards by printing is reduced, the resolution ratio of images can be greatly improved, simultaneously, the cost is reduced, in addition, an
oxide coating is used for replacing an
aluminum foil to be used as the
blocking layer, the problems of difficult
recovery and difficult degradation caused by
aluminum foil discharge are reduced, and simultaneously,
high oxygen blocking performance is provided.
