Michelman in Digital Printing Preferred HP partner since 2006 for inline and offline primers Manufacturer of DigiPrime®, Sapphire, Michem® In-Line Primer products and Topaz Products used by lots of printers, converters, HP approved media centers and substrate manufacturers Network of direct sales, agents and distribution network serves Indigo customers worldwide Developed specific inline primers for the new HP Indigo 20000 & 30000 digital presses

HP Indigo 20000 Wide web digital press for Labels Flexible packaging Integrated PUW: Priming and unwinding unit Gravure coater for inline priming What is new and different: Enabling applications that have not been done digitally so far!

The challenges of Digital Printing in Flexible Packaging? Print is just the decoration of the packaging! Typical long run lengths Majority is reverse printed and laminated to second film Lamination equipment is designed for long run lengths Curing time of lamination up to 7 days Requirements of packaging resistance to Moisture Chemicals Oxygen Grease Temperature

DigiPrime® 050 Design & Value Lamination bond strength is the main extra requirement! In conventional printing special inks are used for lamination Sealant adhesive Outer Film Primer Inner film Print

DigiPrime® 050 Design & Value While keeping advantages from other primers Developed for performance in different applications Pre-Laminated Structures (Surface Print) Single Film (Surface Print) Lamination Structures (mostly reverse print) Good adhesion to printed film (PP, PET, PE) Good lamination bond strength when laminated to a second film OPV adhesion for flexible packaging and label applications Improves the transfer and adhesion to film and metalized film substrates Suitable for food contact Runability in the PUW Water resistance

Structures – Single Film and Pre-laminating Corona treatment on printed substrate is essential OPV needs to be applied (Post printing) for: Upgrading heat-seal resistance) up to 160C. Water resistance (Refrigerator, Freezer) Modifying coefficient of friction (Static and Dynamic) Others Various suppliers of OPV’s water-based, solvent- based or 2 component solvent-based

Structures – Single Film Surface Print PET Paper BOPP PE (B)OPA

Structures – Pre-laminated Surface print PET/PE PET/ALU/PE Paper/PE/ALU/PE BOPP/PE OPA/PE More are under evaluation

Structures – Lamination Reverse Print Corona treatment on printed substrate is essential Corona treatment on the inks, when applying the lamination adhesive is essential Corona treatment on the sealant film when laminating can improve the bond strength Adhesive suppliers who can provide different lamination adhesives: Water-based 2 component solvent-based 2 component solvent-free

Structures – The Pyramid Lamination PET/ALU/CPP PET/ALU/OPA/CPP High Retort, 134 C Retort Aggresive Goods Severe conditions. Pet Food High Performance. 10% MS PET-AlOx or SiOx/OPA/CPP OPA/ALU/CPP OPA/CPP Medium High Performance. 10% MS Clear Retort, 121 C, boiling Bag, Aluminium Packaging, Food,Detergents, oil , cosmetics PET/ALU/PE Multi Substrates en Processes (Pouches), Hot Fill, Cosmetics, Seasoning Detergent.

Structures – Lamination Reverse Print PET/PE PET/ALU/PE BOPP/BOPP BOPP/Met BOPP BOPP/PE This covers a big part of the so called General Performance. More are under evaluation. Bond strength values of 3.5 N/inch and above can be obtained.
