The 4 Types of Laser Holographic Anti-Counterfeit Packaging Film

Anti-counterfeit film emerged in response to cutthroat market competition. It comes in many varieties; laser holographic film is the most widely applied, and it falls into four types.

This technology organically fuses fluorescent security features with conventional holography. Its hallmark is that the fluorescent layer sits not on the film's surface but within the laminate, making the film far harder to counterfeit, as well as abrasion- and solvent-resistant. Plate-making and volume production are extremely complex — requiring costly lasers, photolithography plates, embossing machines, coaters, slitters, and metallizers — and the material draws on optics, chemistry, cryptography, physics, and information science, so imitation is very difficult. It comes in two forms: a stamping foil, and a film printed to order with colorless fluorescent security text or graphics — invisible in natural light but crisp and clear under UV light.

BOPP, PET, or PE. The organic resin reflective layer uses polyurethane, polystyrene, or amino resins capable of high single-layer refraction. Coating the film base with this organic resin reflective layer and then printing the holographic image layer onto it yields a practical, flexible, transparent holographic security film.4. Flexible holographic security film

Flexible holographic security film comprises an organic film base, a reflective layer, and a security-image layer. Structurally, the reflective layer — a high-refractive-index organic resin — is coated onto the film, and the security image is printed onto that resin layer, forming the grating of the holographic image. Suitable film base materials include

Ten Causes of Label Fly-Off in Die-Cutting — How Many Do You Know? (Part 2)

06 Facestock too thick or too stiff

The thicker or denser the label facestock, the higher its stiffness. Once die-cut, stiff labels passing over relatively small-diameter guide rollers easily lift at the leading edge and separate from the liner —

"fly-off" — and they also tend to drop or fly off during feeding on automatic applicators. Thick (for example, laminated), stiff, high-density label materials are therefore unsuited to small labels.

If the die blade picks up adhesive as it cuts through the adhesive layer, it can lift the label's edges (locally) off the liner as it retracts, leaving them pre-released. Small labels are then especially prone to07 Adhesive on the die blade pre-releasing label edges
