Logistics student talks about load securing in digital Expert:innentalk in front of around 1,600 participants

Focus on the strength behaviour of stretch film

When it comes to securing goods in transit, stretch film is often used. It is considered an all-rounder when it comes to securing loads. But is it really? Logistics student Jamo Lasse Randhahn looked into this question for his bachelor's thesis. He was able to present his initial findings at a digital training event organised by Bremen-based Battermann & Tillery GmbH. Around 1,600 people took part.

It is very important that goods are well secured during transport. Otherwise they could shift, which can lead to serious accidents. In such cases, experts are often called in to find the cause. Jamo Lasse Randhahn, who is studying transport/logistics at Bremerhaven University of Applied Sciences, not only completed an internship at one such company, but also wrote his bachelor's thesis. Battermann & Tillery GmbH is an international general average agent. The student took a critical look at the strength behaviour of so-called stretch films. "During my internship, I was allowed to accompany the experts when they were looking for the reasons why a load secured with film had shifted. As there were a few of these cases, my supervisor had the idea of offering online training on this topic. He then asked me if I would be interested in presenting my findings," says the student. 

According to Jamo Randhahn, two very opposing views dominate when it comes to the use of the film. Some experts consider it unsuitable for effectively securing cargo, while others overestimate its value. For the student, this cannot be generalised. "The film can do a lot, but only under certain conditions. It depends on the number of wrappings and how stably it is packed. And not every film is identical in terms of dimensional stability and tear resistance. A lot of research is now being carried out in this area, for example into environmentally friendly materials such as paper. From a sustainability point of view, it's good if the film holds securely even with just a few wrappings," he explains. In general, the film is becoming increasingly stretchable and better, which increases load security. 

During the one-hour Expert:innentalks, moderated by Managing Director Nico Nölder, Jamo Randhahn presented typical cases of damage during transport that could be traced back to inadequate load unit securing with spiral-wrap stretch film. He discussed the special features of various films and applicable testing standards and made recommendations on how transport damage could be avoided in future. In addition to Jamo Randhahn, Prof Dr Dieter Heimann also took part in the online format. He heads the packaging laboratory at Bremerhaven University of Applied Sciences and is an expert when it comes to the correct securing of landings. The event was streamed online from the premises of Bremen-based Streamlab Studios & Events GmbH in Bremen. Around 1,600 people took part. "During the talk, I blanked out the fact that so many people were watching. Instead, I focussed on my talk and the conversation. It was a great opportunity for me and good practice for the defence of my bachelor's thesis," says Jamo Randhahn.
