Polytec in Guatemala has installed a Comexi F2 ML, CI flexo press several months ago. Óscar Escobar, manager of the Guatemalan plant, says that in the past months, Polytec has been able to verify the performance of the new press and confront the current challenges faced by converters in the flexible packaging market. The rapid job change, high quality, and consistency during printing of the new press have been impressive.

 The Comexi F2 ML incorporates the innovative positioning system of doctor blades with low friction pistons, a robust impression body structure, and carbon fiber air mandrels with hydraulic intermediate sleeves. The wide upper platform encompasses an entire heating and drying system, consisting of a five-meter tunnel, and two independent systems with automatic air recirculation regulated by the concentration of solvents. 

As a result, the Comexi F2 ML is consistently capable of the highest performance of printing at a speed of 500 meters a minute. Furthermore, the press can be equipped with an advanced control system to facilitate output quality, including a fully automatic pressure adjustment and registration system based on the machine’s video system monitoring the PDF file of the print job. The press can also access the Comexi Cloud digital services platform.

With the newest CI flexo press, there have already been five occasions where Polytec has trusted Comexi as a benchmark provider of central drum flexo printing services. The purchase of the Comexi F2 ML completes a relationship of more than 20 years. The trust is built on the equipment’s robustness and the impeccable Comexi after-sales service in the region. Comexi is hugely proud to include Polytec among its customers, a company with a character of quality and innovativeness, and one which has been awarded several competition awards in Central and North America.

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.
