UV embossed films

Among a wide range of Holostik’s products and solutions, UV embossed films have garnered massive demand and popularity due to their supreme aesthetic and strong visual appeal which makes the client’s product highly saleable. UV embossed films are mainly polyester films coated with UV curable resin, which are later cured by high power UV light at the time of embossing. UV embossing technology helps to produce higher quality lens/3D effects compared to hard and soft embossing processes.

UV embossing is a roll-to-roll manufacturing process consisting of 4 steps:

The coating process: A flexible substrate film such as polyester is unwound from a reel and then a liquid UV curable resin is coated on the bottom side of the film. The film is dried to remove the solvent from the resin.

Curing process: When the film is being embossed a high source UV light cures the resin.

Rewound: In this stage the completely cured embossed film is rewound on the reel.

Metallising: In this process, the UV layer is sandwiched between the metallising and film layers to form the final product.

The UV embossed film provides strong brand appeal to the product and makes it look unique on the shelf. The film is highly durable and thus, the effects on it remain unchanged until the end of product’s life span. It can include wide variety of effects like CRI (crystal relief image), PRI (platinum relief image), lens etc which gives it a distinct look. In addition, the film also includes anti-counterfeiting features embedded in the customised artwork.

The UV embossed film comes with thickness of 12- and 23-microns PET for carton and 50- and 36-micron PET for labels. UV coating comes from 3- to 7-gsm and available as metallised/ transparent. The film can incorporate any customised effects and more than 20 generic effects, texture, lens, images, and pillar of light.

Applications

The UV embossed films can be used to make 3D UV embossed labels and 3D UV embossed folding cartons. While UV embossed labels can be made with or without laminating the film with paper, UV embossed cartons are made by laminating the film with paper board.

The UV embossed films and its applications have changed the world of packaging forever. The films have become popular among FMCG, pharma, nutraceutical, personal care, and many other industries. This is due to the incorporation of various aesthetic and visually appealing effects and designs, which adds value to the final product.

The following are some of the labels and cartons made with UV embossed films:
