SEI Laser’s systems enable innovative solutions such as easy-opening and closing as well as easy-breath, ventilation, and window packaging. Its new line of laser systems are designed for laser cutting, laser scoring, macro and micro-perforation of different materials such as PE, PET, PP, nylon, PTFE, laminated film, and paper. An important patented feature is the overlapping of laser scoring which enables laser scoring without gaps between two repeats.  SEI Laser’s patented window lamination is gaining high acceptance in Europe as its Cross Web series laser unit can be mounted or retrofitted on any solvent less laminator. 

SEI Laser’s main features are the precise and selective removal of material removal, laser perforating capability, and repeatability of the process. Up to 400 m/min can be reached in Cross Web (CW) laser cutting, laser scoring, and micro-perforation with its proprietary beam steering optics and galvanometric heads depending on the pattern. And, over 500 m/min can be reached in Web Direction (WD) laser cutting, scoring, and micro-perforation with fixed-optics heads. The all-digital process allows rapid changes of work and a significant reduction of downtime and costs.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Packaging South Asia’s balanced industry journalism and help sustain us by subscribing.
