Labels are the most common in the nutraceutical packaging industry. The reason for this is becuase; labels mostly run on a digital press. You can also apply almost any effect on a supported structure. For instance, spot matt/spot gloss raised tactile, cold foild, and much more. For example, when using a silver BOPP allows us to mimic the metallic effect inks.
Pouches are more complicated to produce than labels and shrink sleeves. To create a stand-up pouch requires machinery with a broader web press such as an HP20000. However, flat pouches and stick packs, typically manufactured with a narrow web press machine, which widely found in the packaging industry. There are only a few manufacturers in the U.S. who utilize this technology. Here are the different types of pouches.
It is a type of labeling application in which labels are printed on film (PVC, PET, PETG, or OPS) and then shrunk tightly around a container (glass, plastic, metal) by either manual application, heat or steam tunnels, conforming to the shape of the receptacle. Sleeves often cover 360 degrees, from top-to-bottom, allowing for a greater area for graphics and content.
It is an evolving printing process that has risen in popularity with low volume runs and seasonal packaging productions. It doesn’t require plates or set up waste with a minimum quantity of 1,000, allowing for reduced costs and lead times. Its quality has grown with the technical improvement of CMYK color mixes being able to match a higher number of Pantone inks for full-color jobs.
Utilizes flexible plates that transfer the inks onto almost any type of flexible substrates. The film printed using a reverse printing process or surface-printed paper using foil or film materials with up to 10 colors. Flexography uses water-based and UV curable inks offering excellent print quality for 4-color process and Pantone matching colors. It is mostly suitable for high-volume printing and for custom packaging that requires special effects and finishes many times impossible to achieve with digital printing.
It is a high-speed, high-quality printing process. The images then engraved onto a cylinder, and like flexographic printing, uses a rotary printing press. However, this will mostly for high-volume print in packaging. It delivers a full range of tonal values in photographs, and the cylinders can last for millions of impressions.
