example 1

[0010] Example 1: A holographic anti-counterfeiting polyester base film with a thickness of 15 μm, one of the surface layers is a holographic anti-counterfeiting surface layer, and the other surface layer is an ordinary polyester surface layer.

[0011] In this example: the thickness of the core layer is 11 μm, and selects 70% film-grade bright crystalline polyester chips and 30% polyester base film trimmings and granulated chips by weight percentage, and makes after uniform mixing; two The thickness of the surface layer is 2 μm respectively, among which the holographic anti-counterfeiting surface layer is made of 100% non-crystalline polyester chips, and the ordinary polyester surface layer is made of 70% film-grade bright crystal polyester chips and 30% additives by weight percentage The carrier chip is made after uniform mixing. The additive carrier chip contains crystalline polyester and additive silicon dioxide, wherein the content of silicon dioxide is 3000ppm by weight, ...

[0021] Example 2: A holographic anti-counterfeiting polyester base film with a thickness of 15 μm, one of the surface layers is a holographic anti-counterfeiting surface layer, and the other surface layer is also a holographic anti-counterfeiting surface layer.

[0022] In this example: the thickness of the core layer is 11 μm, select 65% film-grade bright crystalline polyester chips and 35% polyester base film trimmings and re-granulate chips by weight percentage, and make after uniform mixing; One holographic anti-counterfeiting surface layer is made of 90% non-crystalline polyester chip and 10% additive carrier chip by weight percentage, and is made after uniform mixing, and the thickness is controlled at 1.8 μm. The other holographic anti-counterfeiting surface layer is made of 80% by weight percentage Amorphous polyester chips and 20% additive carrier chips are prepared after uniform mixing, and the thickness is controlled at 2.2 μm. The additive carrier chips contain crys...

Abstract

The present invention relates to one kind of counterfeit-resistant polyester-base film which contains two intrinsic surfaces and two exterior ones, and everyone of the intrinsic surface has a definitive proportional crystallizing polyester and polyester-based film trimming materials. One of the extrinsic surfaces is a holographic counterfeit-resistant film, the other is a holographic counterfeit-resistant film or a generic polyester-based film. The holographic counterfeit-resistant film contains 10-100 percent amorphous polyester and 0-90 percent additive carrier according to mass percent. The generic polyester-base film contains 50-90 percent crystal polyester and 10-50 percent additive carrier according to mass percent. The additive carrier talked about upward contains silicon dioxide, kaolin, calcium phosphate or barium sulfate, besides crystallizing polyester, and the content of the additive carrier is 3000pp which is counted according to mass percent. The holographic counterfeit-resistant polyester-based film, so that the holographic counterfeit-resistant design can be die stamped at first hand. It will increase of efficiency, reduce the cost of production.

Description

technical field [0001] The invention relates to a polyester film, more specifically a holographic anti-counterfeiting polyester base film. Background technique [0002] With the development of science and technology, anti-counterfeiting packaging of various products has been widely used, and anti-counterfeiting technology has also developed rapidly. In recent years, holographic anti-counterfeiting marks integrating various anti-counterfeiting technologies have been widely used in product marks in the fields of food, medicine, cosmetics, audio-visual products and clothing. The holographic anti-counterfeiting marks of these products are colorful and three-dimensional. , full of dynamics, under ordinary light, hidden images and information will reappear, when the light is irradiated from a certain angle, new images will appear, which not only plays an anti-counterfeiting role, but also adds The ornamental value improves the packaging grade. At present, the base film used for ...
