Rotomec 50th-anniversary open house shows off gravure-print, lamination
The 250 converters from across the globe who attended the recent Bobst Rotomec 50th Anniversary Open House were treated to an unusual display of high-tech gravure-printing and laminating demos. The flexible-packaging innovations:
The new RS 4003 MP HS gravure press for medium to long runs of printed materials. It achieves speeds of 1,600 fpm and features a new printing-trolley design for quick changeover of the whole inking system and gravure cylinder, or alternatively, of only the gravure cylinder. A 6-color job on 12-micron PET film was demonstrated along with the new TAPS (Total-Automatic-Pre-Register-Setting) sequence. Less than 350 ft of waste material was generated.
The Rotomec MW (Minimized Waste) 80 gravure press. Shown printing a 6-color job on 20-micron BOPP film, the 800-mm-wide MW press is aimed at short-run production. Job preparation is entirely done on floor level by a single operator using the TAPS system.
The Rotomec SL 850 solventless laminator. The duplex-configured unit ran two clear 20-micron BOPP films with 1.8 gsm of solventless adhesive at 1,900 fpm. A flying splice was performed at full web speed.
The Rotomec CL 850 duplex laminator. The system, with more than 30 installations worldwide, features the Rotomec flexo-coating system and was shown laminating a 6.35-micron aluminium substrate to a 12-micron PET film. The CL 850 enables a lower coating weight of solvent-based adhesive at speeds to 1,400 fpm; it also performed a flying splice at full web speed.
Uflex Ltd. to invest $250 million in new flex-pack film projects
The New Delhi, India-based fim maker and flexible-packaging converter says it will spend more than US$250 million in the next two years on various international green/brownfield projects. Among the initiatives:
- A second line for PET films (capacity of 26,400 metric tons/yr) in Mexico with startup in Q1 2011.
- A PP and polyester film project in Egypt (35,000 metric tons/yr of BOPP film; 30,000 MTA of PET; 12,000 MTA of CPP) with complete startup in Q3 2011. Total cost about US$135 million.
- Expansion of Indian capacities for flexible-packaging products involving a total investment of around US$60 million, expected to be fully commissioned by Q1 2011.
