Problems solved by technology

[0003] In the prior art, stencil seams will inevitably be formed during the printing process of BOPP holographic film, and unqualified products will be formed in the subsequent application of BOPP holographic film. These unqualified products must be manually sorted out, which is troublesome
In addition, the existence of seam will cause a certain waste of material

Embodiment Construction

[0025] Such as figure 1 As shown, the method for making BOPP seamless holographic film is characterized in that it comprises the following steps:

[0026] 1) Unwinding: The continuous plate unwinding device 1 and the BOPP base film unwinding device 8 constitute an unwinding unit, and the continuous plate and the BOPP base film are unwound synchronously;

[0027] 2) Preheating: BOPP base film is first heated to 120-150°C in the preheating unit;

[0028] 3) Embossing: The preheated BOPP base film and the seamless continuous plate are compositely embossed in the embossing unit 3 to obtain a seamless BOPP film. The embossing temperature is less than 50°C and the embossing pressure is 0.1-0.5 MPa, the embossing speed is 20-50m / min;

[0029] 4) Cooling: the BOPP film is peeled off from the continuous plate after being cooled by the cooling unit 4;

[0030] 5) Winding: The continuous plate winding device 5 and the BOPP holographic film winding device 6 constitute a winding unit, a...

Abstract

The invention discloses a BOPP (Biaxially-Oriented Polypropylene) slot-free holographic film and a preparation method thereof, belonging to the technical field of anti-counterfeiting printing. The BOPP slot-free holographic film is characterized by being free of slot and prepared by impressing a continuous panel without the slot, wherein the continuous panel comprises a flexible substrate; and an imaged coating is attached to the substrate and carries holographic information. The BOPP holographic film has no slot, can save the materials and prevent manual picking of unqualified products when in later use and is convenient to apply.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing, and in particular relates to a BOPP seamless holographic film and a preparation method thereof. Background technique [0002] BOPP film has a series of excellent physical and mechanical properties and printing properties such as light weight, non-toxic, odorless, moisture-proof, high transparency, high barrier property, high impact strength, flat shape, stable size, etc. The production process is mature, The price is reasonable and the pollution is small. It is widely used in food, medicine, daily light industry, clothing, cigarettes and other packaging materials. BOPP holographic film (or BOPP anti-counterfeiting base film) is a base film with holographic information (text, pattern) , it can be used directly for packaging, or it can be combined with paper to make a packaging box, or it can be used for packaging after evaporation of aluminum, or it can be aluminized and then ...
