Description

DESCRIPTION

Film for product packaging and use thereof

OBJECT OF THE INVENTION

The object of the present invention is a new film for packaging products that has security measures due to printing with certain types of inks to hinder counterfeiting and the use made of it to package high-priced products.

It is about looking for some type of solution that applies security on the transparent film with which various types of products are packaged that are marketed at different points of sale. Mainly focusing on products from the perfumery-cosmetic range, tobacco, medicines or other consumer products of medium-high price and that currently in a first visual and tactile examination no type of printing or security mark is appreciated on the coating film.

The owner of the present invention, as a security printer and knowledgeable about the properties of certain inks and designs on different printing supports, has developed a transparent film printed with security measures-inks.

BACKGROUND OF THE INVENTION

Until now, different manufacturers of films for packaging products are known that have a series of advantages and disadvantages such as:

- Rolling Optics

Advantages:

- Effects on translucent film.

- High quality and definition lenticular printing.

- The technology is protected by patents EP3453537, US2017336644, US2019137774 and others.

Disadvantages:

- Patented product / technology and depends on a single manufacturer.

- Monochrome effect (black and white)

- Limitation by minimum film thicknesses. > 50 microns.

- To integrate it into BOPP films requires 2 processes, 1st manufacture of the “rolling optic” effect 2nd integration to BOPP film.

- High price and delivery times.

- Manufacturers of holograms / holographic films:

Advantages:

- Applicable effects on translucent films.

- Allows 3D effects, dynamics, color diffractions and very high resolution. Disadvantages:

- There are many manufacturers.

- Master generation costs (holographic plates), medium-high (depending on quality and technology)

- Generally the film is polyester, a second process is required to transfer the holographic effects to the BOPP film:

- The effects are generally opaque metallic, except in demetallised holograms, but the latter are expensive and are only used in very high security products.

- Medium-high delivery times.

- Medium-high price (depending on quality and technology)

- Flexible packaging printers:

Advantages:

- They have adequate means and experience in printing on synthetic supports in rolls.

- They generally use flexo presses, which have medium-low production costs.

- Some flexo presses incorporate in-line ink-jet numbering bodies, hot / cold stamping, screen printing, embossing bodies, die-cutting, etc. which allows multiple additional effects to be made to printed media online. - Medium-short delivery times.

Disadvantages:

- They are not specialists in designs, inks and security measures.

- Flexo printing has certain limitations in terms of printing resolution.

DESCRIPTION OF THE INVENTION

In order to alleviate the drawbacks of the products of the aforementioned manufacturers and highlight the advantages, in addition to adding other additional anti-counterfeiting advantages, the following factors are considered.

- That the film produced is of interest and useful to potential clients.

- Customizable. Offer a film for personalized packaging for different clients, sectors and product ranges.

- Maintain the transparency of the film, without damaging the visibility and design of the packaging.

- That the resulting film is robust / resistant against possible copies-imitation of possible competitors.

- That the effects applied (printing) on the film can be appreciated (absence / presence) through visual inspection, but in a subtle way. Glossy / matte contrast.

- That different levels of security can be applied to the film, being able to offer a solution that complies with the 3 traditional levels of document / fiduciary security.

- That the film transformation process can be carried out in a single step by the machine for its production and thus be able to offer short delivery times.

- A single transformation process to optimize costs and achieve a film that can be sold with a high profit margin.

As a result of the study of these factors, the film object of the present invention has been developed, which consists of reels intended for packaging machine-lines. The widths of the film reels are variable (depending on the type of box-case-packaging to be packed). The mandrel is always the same, and the outer diameter of the reels for packaging machines is usually 24 to 28 cm.

The production process is considered as rotary printing, UV drying inks. Roll to roll printing. Input reels of maximum width 52 cm. and an approximate outer diameter of 70 cm. The length in meters of each input coil will depend on the thickness of the film. For 30 microns, 10,500 linear meters enter.

From all this, reels of film object of the present invention result, which contain the following printing and characteristics:

- Design of a background of repeated motifs, without registration.

- Density of repetition of motifs (images / logos, etc), medium-high;

enough to cover the entire area of the product to be packed, but without affecting the visibility of the packaging it contains.

- 2 invisible UV luminescent inks: Yellow Blue. In addition, between the two overlap in some motifs to obtain a third fluorescence (yellow blue = white)

- Includes iridescent ink motifs. They will be done in flexo body.

- It includes an element that will include translucent ink (varnish) equipped with a taggant particle detectable by means of the Sicpa IR HD21 device.

- Includes "original", "authentic" texts, etc.

- Includes high-definition-resolution design elements; fine lines, guilloche, micro-texts, etc.

In addition to the advantages due to the anti-counterfeiting measures added, it should be noted that current film users would not notice any difference in their way of working, since the film is the same as they currently use, it would simply contain the added security measures without modifying any physical characteristic of the film.

PREFERRED EMBODIMENT OF THE INVENTION

In a preferred embodiment, the product packaging film is characterized by being transparent bioriented polypropylene (BOPP) whose thickness can vary between 25 and 45 microns and that is treated on one or both sides with an acrylic coating and / or with a corona treatment in which character or figure motifs referring to the manufacturer of the product or with words such as "Original", "Authentic" or similar have been printed with at least one of the following inks:

- two invisible UV luminescent inks: yellow blue and additionally some motifs of characters or images can be interposed between the two invisible UV luminescent inks obtaining a third fluorescence.

- iridescent ink to be made on a flexo body.

- translucent ink (varnish) endowed with a taggant particle detectable by means of an IR HD21 device from Sicpa.

The film for packaging products has a design of a background of patterns of characters or images repeated and without registration and the density of repetition of patterns of characters or images is medium-high covering the entire area of the product to be packaged, but without that impairs the visibility of the packaging it contains.

The use of film for product packaging is to add anti-counterfeiting security measures in the packaging of high-priced consumer products and especially in cases where counterfeits are more frequent, such as perfumery-cosmetic products, tobacco , medicines.

Once the nature of the present invention has been sufficiently described, as well as some ways of putting it into practice, it only remains to add that said invention may undergo certain variations as long as said alterations do not substantially vary the characteristics claimed below.
