Trailblazers in Rotogravure and More!
Printpack leads the packaging industry in manufacturing capabilities. Our vertically integrated manufacturing approach to flexography, rotogravure, and digital printing methods have garnered much recognition throughout the years, and we couldn’t be more grateful. Our plants are FSSC 22000 and GFSI certified. FSSC 22000 is an ISO certification system for evaluating food safety management systems. GFSI is a continuous improvement platform for food safety management from the Global Food Safety Initiative. Printpack is committed to providing award-winning, safe, and quality products to our customers day in and day out.
- A solvent/water based or solventless lamination is used to combine two or more layers
- The adhesive can perform additional functions, such as: resistance to chemical migration, maintaining bond during high temperature processing, combining layers without adding bulk and barrier
- Annular die
- Forms by melting into tube with multiple distinct layers
- Air cooled, therefore higher crystallinity
- Coat hanger die
- Forms melt into single sheet with multiple distinct layers
- Rapid quenching with cooled chill roll
- Printing options that go beyond the capabilities of flexo and roto such as variable content and hyper-customization
- Custom codes for gaming and personalization
- Reduced risk to experiment with new designs and packaging formats
- More timely and relevant product offerings
- Packaging for seasonal/calendar/event-based promotions and limited editions
- Packaging for heat-seal or cold-seal applications
- Order sizes that fit product demand
- Order sizes that fit marketing campaigns
- No investment in printing plates or engraved cylinders
- Reduction of obsolete inventory
- Molten plastic (or extrudate) is used to combine two or more layers
- The extruded can add or enhance properties, such as: bulk, toughness, puncture resistance, barrier (gas, flavor/aroma, moisture, chemical) opacity, and zero cure time
- Flexography is a method of direct rotary printing using raised image printing plates. First, fluid ink is applied from the inking system to the anilox roll. The anilox roll is a metal cylinder consisting of microscopic cells. Metal doctor blades shear excess ink from the surface of the anilox roll transferring a thin, controlled layer of ink to the surface of the printing plate. The flexible plates, which contain the image, are adhered directly to the plate cylinder utilizing a double-sided tape called sticky back. The substrate passes between the plate cylinder and the impression cylinder transferring the ink from the surface of the printing plate onto the substrate. This process will occur for each individual ink color making up the package design.
- Rotogravure is a method of direct rotary printing using a relief printing process. The packaging design is etched directly into a metal cylinder with microscopic cells. The amount of ink released to the substrate is controlled by the depth and size of the individual cells. Fluid ink is applied directly to the engraved cylinder. Metal doctor blades shear excess ink from the surface of the engraved cylinder. The substrate passes between the engraved cylinder and the impression cylinder transferring ink out of the recessed cells in the engraved cylinder onto the substrate. This process will occur for each individual ink color making up the package design.
