“It would be worthwhile to calculate and compare the power cost per kilogram slit before making your next purchase decision.”

The extent to which power consumption can vary from machine to machine for the same application, or for that matter even for the same set of jobs, would surprise many flexible packaging converters. While a detailed discussion on the underlying factors that influence power efficiency is beyond the scope of this article or series, the usual suspects for this evaluation would include the selection of motors, the power distribution grid, the selection of gear ratios, and the measures taken to restrict the torque of rotating members.

The data available with most manufacturers as regards the power efficiency of their equipment is scanty at best, and misleading at worst. However, if you do have the benefit of more than one machine running nearly the same set of jobs in your plant, it would be worthwhile to calculate and compare the power cost per kilogram slit before making your next purchase decision.

Where do the components come from?

“Any due diligence while evaluating a slitter rewinder purchase would be incomplete without an in-depth survey of the bought outs used in the equipment.” Like any other machine, a slitter rewinder includes its fair share of “bought outs” or parts that are procured from a third party that specializes in the respective domain. Prominent examples include motors, drives, PLCs, and pneumatic components which are common to most industries, and web-handling devices such as reel chucks, web guides, rubber rollers, and differential shafts which are particular to the converting industry.

These bought outs play a vital role in the functioning of the machine and as such, the performance of the machine depends, to a large extent, on their working well and together. Besides, many breakdowns of the machine can be traced to a malfunction in these bought outs. Therefore, any due diligence would be incomplete without an in-depth survey of the bought-outs used as standard (remember, it is one thing to make use of a reputed brand on the insistence of a customer and quite another to have it as a default, stemming from a ‘no compromise’ policy of the manufacturer). Apart from knowing which criticals come from where, how easy is it to access, service, repair, and or replace them and what are the costs?

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are grown similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans and to inspire and mobilize our editorial and advertising teams!
