Last year BillerudKorsnäs and Haver & Boecker published a total of nine sack packaging norms. These norms cover the basics and some of the most critical factors relevant to pack powdered goods. The reactions in the market show that the norms support the work of bulk goods manufacturers. They provide a helpful guideline for determining the optimal packaging process and the perfect sack packaging for products to be filled.

BillerudKorsnäs and Haver & Boecker have decided to develop further norms after receiving positive feedback worldwide jointly. The sack packaging norms contain recommendations for creating and using packaging solutions and processes and defining basic standard know-how or standard procedures. They provide orientation for questions that manufacturers of bulk materials confront daily.

The cost of empty sacks

Both companies have experienced that customers are increasingly paying attention to the cost of empty sacks. The right quality and design of the empty sacks are crucial, as they directly determine the performance at all steps in the value chain. For example, a particular sack design may be cheaper, but it costs millions in lost production if it fills slower on the filling machine.

Bulk goods manufacturers have a direct influence on all factors through the design of the packaging process. Here, the Sack Packaging Norms indicate how bulk solids manufacturers can ideally act in this area of conflict between cost and quality. “Together, BillerudKorsnäs and Haver & Boecker now offer a set of recommendations to minimize problems and maximize performance in the packaging chain. If manufacturers and users of paper sack packaging follow the recommendations and guidelines and implement the usage of these norms in their supply chain, efficient and effective packaging production, filling, handling, storage, and transport of the end products will be ensured,” says Mikael Peterson, Technical Service director at BillerudKorsnäs.

Expert knowledge from both companies is within the sack packaging norms. BillerudKorsnäs contributes with years of expertise in packaging paper production, practical experience, and analytical tests, design, and developments at the BillerudKorsnäs Packaging Development Centre. Haver & Boecker contributes with its extensive experience in filling technology and handling powdered bulk materials. “In the Haver Institute, we run more than 300 packaging trials per year together with customers. Many meetings and discussions with our customers and converters show us again and again that people are looking for such guidelines to perfect packaging. The information presented within these norms are collected throughout years of experience, and we are pleased to see they will be used worldwide,” explains Thomas Hilling, manager Haver&Boecker Institute.

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.
