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, ...

[0022] 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.

[0023] 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 invention relates to a holographic anti-counterfeiting polyester base film, which comprises two surface layers and a core layer. The core layer contains a certain proportion of crystalline polyester and polyester base film trimming components, and one of the surface layers is a holographic anti-counterfeiting The other surface layer is a holographic anti-counterfeiting surface layer or an ordinary polyester surface layer. The holographic anti-counterfeiting surface layer contains 80%-100% non-crystalline polyester and 0-20% additive carrier by weight percentage. The polyester surface layer contains 50%-90% of crystalline polyester and 10%-50% of additive carrier by weight percentage. The above-mentioned additive carrier, in addition to containing crystalline polyester, also contains additive silica , kaolin, calcium phosphate or barium sulfate, wherein the additive content is 3000ppm by weight. The holographic anti-counterfeiting polyester base film can directly mold a holographic anti-counterfeiting mark pattern on the holographic anti-counterfeiting surface layer, thereby improving efficiency, reducing production costs, and expanding the application field of anti-counterfeiting products.

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 ...
