Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

Embodiment one

Please refer to Fig. 1, present embodiments provide a kind of packaging film, comprise the first film layer 10, decorative layer 20, adhesion layer 30, aluminium coated 40 and the second thin layer 50 that are cascading.

The first film layer 10 is high density polyethylene (HDPE) (High Density Polyethylene, be called for short HDPE), low density polyethylene (LDPE) (Low Density Polyethylene, be called for short LDPE), linear low density polyethylene (LLDPE) (Linear Low-Density Polyethy-lene, be called for short LLDPE), metallocene low density polyethylene (LDPE) (MAO Low Density Polyethylene, be called for short MLDPE), metallocene linear low density polyethylene (MAO Low Density Polyethylene, be called for short MLLDPE), bimodal linear polyethylene, the cellothene that a kind of in the materials such as bimodal enhanced polyethylene (be called for short delustring PE) makes or delustring polyethylene film.

Decorative layer 20 is attached on the first film layer 10, with display pattern and color.In the present embodiment, decorative layer 20 is one deck ink layeies formed on the first film layer 10 with screen painting.The thickness of ink layer is between 0.005 millimeter to 0.02 millimeter.

Second thin layer 50 is high density polyethylene (HDPE) (High Density Polyethylene, be called for short HDPE), low density polyethylene (LDPE) (Low Density Polyethylene, be called for short LDPE), linear low density polyethylene (LLDPE) (Linear Low-Density Polyethy-lene, be called for short LLDPE), metallocene low density polyethylene (LDPE) (MAO Low Density Polyethylene, be called for short MLDPE), metallocene linear low density polyethylene (MAO Low Density Polyethylene, be called for short MLLDPE), bimodal linear polyethylene, the cellothene that a kind of in the materials such as bimodal enhanced polyethylene (be called for short delustring PE) makes or delustring polyethylene film.Second thin layer 50 is transparent, off-white color or other coloured polyethylene film.

Aluminium coated 40 is attached on the second thin layer 50 by aluminum plating process such as vacuum evaporations.In other embodiments, also first on the second thin layer 50, aluminum plating process can be carried out again after coating.

Combined by adhesion layer 30 between decorative layer 20 and aluminium coated 40.The material of adhesion layer 30 is acroleic acid resins, nitrocellulose resin, polyurethane resins, chlorinated rubber resin, vinyl chloride-vinyl acetate co-polymer resin, polyamide resin, polyester resin, epoxy resin, one in poly-carbonic acid resin, alkene resin, acrylic nitrile-butadiene-alkene-styrene resin etc. or two or morely to mix.The method forming described adhesion layer 30 can use any one general printing process such as such as intaglio printing, screen painting and hectographic printing, or such as spray, the method such as brushing.

In the present embodiment, decorative layer 20 is between the first film layer 10 and adhesion layer 30, and aluminium coated 40 is between the second thin layer 50 and adhesion layer 30.
