Paper Technology

Step 1. Basic converting

Lacquering

Based on multi-lacquering technology the foil material gets pre converted with self developed heat seal lacquers and print primers and is being prepared for printing and further converting. In order to meet the high environmental requirements at Teich mainly water based on environment-friendly lacquers are used which are all supplied by our internal competence and R&D centre for lacquers.
 

Laminating

Applying an adhesive on the foil material and attaching a second reel material such as foil, film or paper laminates are produced (e.g. alu/paper, alu/film) as they are used for confectionery. Repeating this process with an already produced laminate multi layer materials are produced (e.g. alu/paper/alu) as they are used for butter wrappers or waffle foil. At Teich following laminating technologies are available: dry lamination, wet lamination and wax lamination.

Metallizing

In a high vacuum chamber a metallised layer is being applied on film material due to vaporising of aluminum particles. The metallizing can either be applied full coverage or striped. Besides optical value adding the metallizing gives an improved oxygen and steam barrier to film material.

Step 2.  Printing

Rotogravure

Foil material as well as laminates are printed with engraved steel core cylinders and solvent based inks. The design is engraved into a copper layer on the cylinders which are then chrome plated – the excessive colour on the surface is removed with a doctor blade so that only the ink in the engraved cells remains and prints on the substrate. On our rotogravure machines we can print designs consisting of up to 10 colours including back side printing facilities – additionally further converting (such as hotmelt, cold seal or over lacquering) is possible in line.

Step 3. Lamination

Depending on the requirements the lamination of paper based products can be:

• Solvent based & solvent-free
• Extrusion lamination

Step 4. Converting & finishing

Slitting

With our slitting machine we cut our reels into narrower lanes and reel diameter according to customer demands to ensure that it fits to our customers´packaging lines.

Die cutting

With a cutting tool consisting of stamp and die the lids are pressed out of the converted reels. The cutting tools are individually made according to the required shape – the most common shapes are available as standard tools. Additionally we can do in line embossing of the lids with all various kinds of embossing designs. As a special application also sectional embossed or deep drawn shapes are possible.
