Embodiment 2

[0045] Compared with Example 1, except that the preparation process is different, all the others are the same.

[0046] The preparation process of this embodiment is specifically:

[0047] Step 1: Select a suitable water-based paint and color paste with good compatibility for mixing, standardize and adjust the proportion of corresponding materials according to the requirements of hue, pay attention to the order of adding materials (first add the original liquid, then red paste, and finally add yellow paste) , and the frequency and time of stirring (stir manually while adding the color paste, use a special mixer to stir at a uniform speed after all the addition, and the stirring time is controlled at 10-20 minutes), that is, the colored water-based paint is ready for use.

[0048] Step 2: Select 12u PET food-grade composite base film (i.e. PET base film layer 6), uniformly coat colored water-based paint by means of gravure wire to obtain color water-based paint layer 5, pay att...

Embodiment 3

[0055] Step 1: Select a suitable water-based paint and color paste with good compatibility for mixing, standardize and adjust the proportion of corresponding materials according to the requirements of hue, pay attention to the order of adding materials (first add the original liquid, then red paste, and finally add yellow paste) , and the frequency and time of stirring (stir manually while adding the color paste, use a special mixer to stir at a uniform speed after all the addition, and the stirring time is controlled at 10-20 minutes), that is, the colored water-based paint is ready for use.

[0056] Step 2: Select 12u PET food-grade composite base film (i.e. PET base film layer 6), uniformly coat colored water-based paint by means of gravure wire to obtain color water-based paint layer 5, pay attention to generally choose 180 mesh wire, the uniformity of the mesh The amount of coating can be controlled well. The viscosity of colored water-based coatings on the machine is cont...

Abstract

The invention relates to a holographic laser anti-fake colored aluminized double-faced composite food package material and preparation thereof. The package material includes a base paper layer, a PETbase membrane layer, a colored water-based paint layer, an aluminized layer and a water-based environment-friendly composite adhesive layer, wherein the PET base membrane layer, the colored water-based paint layer, the aluminized layer and the water-based environment-friendly composite adhesive layer are compounded on the front and back surfaces of the base paper layer separately from outside to inside in sequence; a holographic laser anti-fake information layer is also printed on the colored water-based paint layer compounded on the front surface of the base paper layer. Compared with the prior art, the package material effectively achieves application in food package and other domains, overcomes defects in current membrane spraying modes in the prior art and has the advantages that the precision is high, the anti-counterfeit performance is great, lasers are gorgeous, and the appearance is novel.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and relates to a holographic laser anti-counterfeiting color aluminized double-sided composite food packaging material and its preparation. Background technique [0002] Food packaging is a large player in the packaging industry, accounting for about 70% of the entire packaging industry. Food companies attach great importance to the selection of product packaging materials. Because plastic packaging is harmful to human health and extremely difficult to degrade naturally, it causes serious environmental pollution and limits its further development in the field of food packaging. In recent years, the development of food packaging paper has become the consensus of the food and packaging industry as the voice of global environmental protection is increasing day by day. The "green packaging" method of paper food packaging is becoming the best substitute for non-degradable packaging due t...
