Tentoma, a new strong player within sawmill packaging of wood and also building materials, insulation materials, geosynthetics, is presenting an exciting machine that can automate and offer clear benefits including removing ergonomic stress for employees.
Watch the video and see the machine working already now before it is being shipped to our partner in Finland. Here:
The machine that can be seen at our Finnish distributor Jartek on stand B-240 is an XL packaging machine for large wood blocks. On the exhibition representatives from Tentoma in Denmark will go into detail on some of the benefits when implementing the machine.
Frank Bruhn ApS (now Tentoma A/S) gets boost by Danish Growth Fund for international expansion with Tentoma and RoRo StretchPack machines
The company Frank Bruhn ApS (now Tentoma A/S), which has developed a unique wrapping solution for large goods, has recently raised money from The Danish Growth Fund. Simultaneously, the company is changing its name to Tentoma while getting ready for further international expansion.
Wrapping of goods is a costly process for production companies around the world. The Danish company Frank Bruhn Aps has developed a new technology, which can relieve the issue.
With a unique wrapping solution using stretch film, Frank Bruhn ApS has already put their machinery in operation in several European countries. An investment from The Danish Growth Fund, is going to boost the international expansion of the company, which as of September 1 changes its name to Tentoma.
Lower costs and better environment
Tentoma has patented elements of a packaging machine that ensures high packaging quality combined with cost saving, less environmental impact and improved work environment. The fully automatic wrapping machine stretches and wraps a tube of plastic foil over large goods from ex. saw mills, building and isolation producers and ensures a close-fitting wrapping.
“With our machines it is possible to package goods up to 6-8 meters long in a 100 pct. sealed plastic, protecting them from external impacts such as water, humidity and contamination. It is especially relevant when it comes to ex. isolation, building materials, wood and textile fabrics rolls. “This way we ensure significantly better packaging quality as well as reducing costs significantly by a reduction in wrapping material and energy consumption compared to traditional solutions. It means that our machines have a very attractive repayment period”, managing director of Tentoma, Henrik Raunkjær, explains.
He continues to elaborate that there are benefits for the environment as well, since the new wrapping technology works without the shrinkage ovens used in traditional package solutions. Thereby, a heat source can be eluded from the workplace, and the energy consumption and CO2 emission is reduced.

Two-digit million investment and new name
The benefits of the new wrapping technology has already brought the packaging machines into the European markets, where they are currently installed in Germany, Poland and Spain and new machines are on their way to Sweden, Austria and Finland.
With an investment from The Danish Growth Fund, the international expansion is exactly the focus moving forward.
Stig Poulsen, partner at VF Venture, is pleased with the investment and sees great potential in Tentoma’s packaging machines.
“Tentoma has managed to develop an innovative and resource-saving solution for an otherwise cost-intensive packaging market. The company is run by a team, who combine many years of experience from the packaging industry with a clear commercial understanding and they have already installed their machines in several European countries. It paves the way to a large potential and the investment from The Danish Growth Fund provides sufficient capital for scaling of i.a. the sales organization, which contributes to the growth and international sales“, says Stig Poulsen.
As part of their growth plans, Tentoma have already hired two more sales representatives and a supply chain manager and expect significant growth in the years to come.
“We are pleased to have an experienced investor such as The Danish Growth Fund on board. To reap the full potential of the European markets, we need to supplement our private investors with a larger investor. With The Danish Growth Fund, we get a strong partner, who makes it possible for us to support large international companies”, says the company’s founder, Frank Bruhn.

How did the 25 years experienced specialist in stretch films create a game changer with Horizontal Stretch Packaging? An Interview about Horizontal Stretch Packaging with founder of Frank Bruhn ApS in Denmark. As of Sept 1st. the company name is Tentoma ApS (now Tentoma A/S).
How did you start with Horizontal Stretch Packaging?
Jensen: Hi Mr. Bruhn, let’s jump right into this. Why did some large building material manufacturers contact you? How did the Horizontal Stretch Packaging journey start? Bruhn: I guess they knew me well enough to seek some advice on how to solve some specific problems. You know, I haven’t been doing anything else for more than 2 decades. But you know what, this time I didn’t have any solution to their problem so hang on.
You see, existing packaging technologies like stretch hood, heat shrink hood, heat shrink tunnel and pallet shrink wrapping couldn’t solve the problem they challenged me with.
Customers wanted to know if it was possible to change existing stretch technology from vertical to horizontal and at the same time solve some of the more critical problems they were experiencing.
Founder Photography, 2011: Frank Bruhn (lower left side) and his brother Gunnar Bruhn (lower right side) founded the company Frank Bruhn ApS in Denmark several years ago. Today Frank Bruhn ApS has gained an international foothold with an established brand based on the horizontal stretch packaging equipment RoRo StretchPack
It all started with a fire in a Heat Shrink Tunnel packaging line
The initial reason was a fire in a factory packaging line caused by a heat shrink tunnel machine. You have a lot of heat exposure in a shrink tunnel and in the worst case it can cause a fire.
This constant fire risk explains the higher insurance costs you pay to protect against potential losses. So, the manufacturer wanted me to explore the possibility of making a machine which could package long products and to get well known problems solved. Also he wanted to get rid of the heat tunnel risk.
Difference between Horizontal Stretch Packaging and other technologies
Jensen: Okay, and in, and before this process, I know, that you have collaborated with both manufacturers like Nordfolien (Stretchfolie - Nordfolien in Germany) and also market leader ExxonMobil Chemical (PFFC-online ) in a collaboration between ExxonMobil Chemical and Frank Bruhn ApS.
I also understand that you later will explain some challenges in going from vertical to horizontal in stretching of PE-films.
But first, please clarify what the difference is between vertical and horizontal stretch packaging equipment.
Bruhn: Sure. We can also later talk about why applying stretch film in general can cause challenges when packaging. Okay, let’s start by taking a look on the difference between the vertical and horizontal technologies. These following pictures illustrate it quite well.
Movie 1: How does the horizontal stretch packaging equipment work? Compared with Heat Shrink Tunnel there are significant savings on PE-Film and Energy.
The horizontal stretch technology is one of a kind compared to vertical stretch hood solutions, pallet wrapping (spiral- or ring wrap) and significantly different to the heat shrink process.
Once the PE-film has been captured by the grabbing unit, it is led to the product lane where components or products will be stretch packed.
When comparing to heat shrink tunnel machines the significant difference is the energy- and film savings that can be achieved. A saving impact can also be seen in the reduced insurance costs to protect against losses in case of a fire due to heat exposure.

Comment on complimentary packaging technologies
Bruhn: So, the heat shrink tunnel and our horizontal stretch packaging equipment both operate in a horizontal way. The stretch hood and spiral/ring-wrap technologies internally have their differences which you can read about on-line on Foodprocessing Technology & Manufaturing.
The traditional vertical stretch hood technology is an excellent end-of-line packaging solution which our customers typically have. Our Horizontal Stretch Packaging machine will often be located as primary packaging before-end-of-line. You can say, that RoRo StretchPack helps to feed the final packaging station.
Some products, e.g. larger building material components and larger insulation material components are today typically running through a manual process or a heat shrink tunnel. Here our customers see the unleashed cost saving potential when replacing these with the RoRo StretchPack. For such larger components or products a traditional vertical stretch hood cannot be applied.
Looking at the performance criteria for horizontal stretch and heat shrink tunnel below, it is obvious that there are some significant differences when comparing for instance operational costs and optical features. Let’s go into this right away.
Performance comparison between Heat Shrink Tunnel and Horizontal Stretch Packaging
Bruhn: If we talk about comparing performance on horizontal stretch technologies it would make sense to compare the newest technology, our horizontal stretch, with the widely applied heat shrink tunnel technology.
We can define various relevant performance criteria that we know are important to our customers including operating costs and savings on energy and film consumption. However, never forget the packaging speed as well as the optical features. Let’s have a look at an extract of a comparison.
Table 1: Performance comparison between Heat Shrink Tunnel and Horizontal Stretch Packaging (RoRo StretchPack) Source: Frank Bruhn ApS
Comments to the comparison Bruhn: Obviously, a comparison between different technologies and equipment’s is not always easy and can even vary from customer case to customer case. We did this comparison in the beginning and included, I think more than 80 parameters. We did it in order to verify that we could introduce a solution to the market that would be extremely competitive. And at the same time be disruptive in comparison with at least heat shrink tunnels.
Challenges in going from vertical to horizontal stretching
Jensen: What were the most critical challenges in going from vertical stretch to horizontal? Bruhn: There were many and once we solved them we also applied for several patents right away to protect these innovations.
When thinking back, I would mention three things in particular; firstly, it’s about controlling the winding and un-winding process 100%. My experience from vertical stretch hood technology has taught me that you need to be focused on these two processes if you want a smooth and reliable end result. The second challenge was huge in the industry and about controlling the film opening problematic. How to smartly open or separate the PE-film coming from the film roll? This has for everyone been the big question. Actually we can write a whole book about this issue.
The problem is that 2 PE-film sides stick together and must be turned into a PE-stretchfilm-tube in order to be stretched. As the film roll gets rolled off you will find that the it gets harder and harder to open or separate. We have now found a way to solve this by introducing a more stationary tool which enables us to operate with a more static film. Now you know what the problem was and I think it would be an idea to take up this topic separately later on in a separate post.
The third critical challenge was to adapt our technology into a horizontal mode. Let’s talk about the winding process first.
100% control of the film-winding and film-unwinding process Bruhn: The winding and un-winding process we can also call film roll-on and film roll-off. This, by the way, led to the name of our final packaging equipment solution; RoRo StretchPack.
It is critical to master this film-winding and film-unwinding process in order to tackle the well-known challenges from all technologies, such as film-wrinkles, holes in the PE-film, precise film positioning and finally the important optical features.
The principle in doing it horizontally is to create a horizontal tube and pull it tightly over the component which is fed-in on a conveyor belt. Well, it is principally a kind of stretch hood in horizontal mode. The components, and not the people, are moving which frees up resources that can be dedicated to other value-added activities.
Jensen: Maybe it is a good time now to watch the video showing the actual roll-on and roll-off process in the RoRo StretchPack solution (Horizontal Stretch Packaging). Let’s see it now.
Movie 2: Horizontal Stretch Packaging - How the innovative roll-on and roll-off process of PE-Film takes place avoiding wrinkles, holes and packaging damages
Bruhn: As you could see in the video our patented roll-on and roll-off process enables us to 100% control the winding and un-winding of the film-material. So we can deliver a 100% sealing proof packaging if this should be required. If not, you still get all the other benefits mentioned during our talk.
PE-Film Savings with Horizontal Stretch Packaging compared to Heat-Shrink-Tunnel
Now, the principle in a heat shrink tunnel concept is that an excessive amount of film is being shrinked. We instead offer an optimized, and much smaller film that is being stretched. Do you see the saving potential here?
We achieve a much lower film consumption and most importantly we can reduce the energy consumption bill and improve the CO2 foot-print of our customers. Most customers care a lot about green packaging and have fixed KPI’s on improving this. In fact, just the energy savings and the film consumption savings, compared to heat shrink tunnel packaging, can give you a very, very interesting ROI besides reducing the CO2 emission.
Jensen: And the challenge in creating a solution that made it possible to operate horizontally?
Bruhn: We needed to focus on as few machine part movements as possible between the actual PE-film-roll, film-feed-in point and the component to be packaged. The thing to know was; where does the product come from and where must it depart after the packaging. We decided to position the PE-film-roll unit right next to the horizontal stretch packaging operation point in order to increase the feed-in-efficiency and packaging speed.
Competitive package speed
In this way we can achieve as a minimum, the same speed, compared to heat shrinking machines. Today we also offer several options, like a duplex PE-film-feed-in or semi-flow packaging. It all depends on what our customers need and want. Today it is no problem to reach an even higher speed. Jensen: I understand that you have had to study intensely whether it makes sense for a customer to change from heat-shrink-tunnel into horizontal stretching. What 1 or 2 things would you recommend to look at here?
Bruhn: Hmm, well, I did mention the energy savings, green packaging and improved CO2 foot print. What many customers also look at is their own value proposition. See, if your products can live up to the value proposition when considering for instance logistics and do a simple 3-step-test yourself.
How to choose the correct packaging solution fit for your logistic
Bruhn: When deciding on your packaging solution you should consider the whole outbound logistic journey. Think about it; you often will have several intermediate loading and unloading points within your own manufacturing facilities, at the logistic forwarder, 1 or 2 logistic international transportation hubs with loading and unloading, unloading at customer, storage, new shipment and then unloading at the final end customer.
All these loading and unloading points calls for well-considered package solutions to sustain them. And, don’t forget the always changing weather elements during the whole journey.
What we see is also that customer geographies and destinations are not static. The packaging should be adopted to always more and more global supply chain developments. Your film-supplier can surely advise you based on their vast experience.
How to check for potential savings and quality improvements on your packaging
Bruhn: My close collaboration for many years with various PE-film manufacturers and distributors has made clear to me that the choice of PE-film, is not where you want to compromise on quality. But be aware. You may need to drive down costs continuously and at the same time ensure excellent quality. Certainly. But what I have seen again and again is that lack of know-how in choosing the appropriate PE-film for the packaging process leads to unnecessary high costs.
Start by making sure, that your machinery is adjusted precisely. Whatever machine we are talking about. Whatever logistic challenges you have. This can lead to significant savings on consumption.
As to the quality improvements, there are certainly a lot of parameters to be aware about and we cannot cover them all here so let me show you just one 3-step-test that you can do yourself without being an expert.
Go to your end-of-line packaging point, or even better, to the last in-house intermediate storage point. Pick out a packaged product and do these 3 steps:

1. Check the optical features!
Figure 7 - Check for optical features of the packaging Source: Frank Bruhn
Does it live up to your value proposition and your customers’ expectations? Will your brand be represented the way you want it to at the final destination?
Will it sustain, without any doubt, the outbound logistic journey towards all your customers considering all geographic destinations? Should it, and is it, 100% sealed against moisture and dirt
2. Make a punctual resistance test!
Figure 8 - Punctual resistance test Source: Frank Bruhn
Is hardly no pressure needed to break the film material? If easy punctured; is it realistic that it will sustain all customer destinations with all loading and unloading points?
3. Test the tearing resistance!
Figure 9 - Tearing resistance test
Does the PE-film-material easily tear down/up/sidewards when tearing in the point where you made a hole in step 2? How will it affect the load resistance of multiple packaged products after several unloading and loading points? Does it imply risks to be aware about for your valued customer?
Bruhn: So, this easy do-it-yourself-test will often give you a good indication whether you should improve something or not. Taking it to the next level will of course mean to carry out the same test at maybe 3 or 4 different customer destinations in different geographic locations.
Jensen: I’m sure there are many other quality check points we can address like the above. However, here at the end, maybe it’s time for you to tell a little bit about the company today.
Bruhn: For me, and my brother who is the co-founder, it is important that the original company values are the same today as when we started years ago. Also after we have grown together with our international oriented customers. To see, that everyone in the company lives up to these same values when performing their jobs, whether in our supply chain, service, sales or management, really makes us proud.
And what really makes me excited is that our RoRo StretchPack solution opens up the minds of our customers. Again and again I hear that they, much better than us, can see the vast opportunities in our solution and the packaging contexts it can be used in.
It’s very simple. At the end of the day they know their supply chain better than any outsiders.
Jensen: Thanks for taking the time for this internal company interview. I also look forward to working together on our upcomming webinars where we will go into detail with the RoRo StretchPack technology and adress savings on film and energy and much more.

Horizontal stretch packaging – Wood Packaging – a big success on Ligna
It was a pleasure for the team of Frank Bruhn ApS to present on Ligna how manufacturers can apply horizontal packaging in wood packaging for their long wood products such as doors, furniture and more of all sizes and shapes.
Example of cost saving (3,2 Eur/Wood Block) in film consumption when using RoRo StretchPack to pack a long wood block
A special stretchfilm applied in the RoRo StretchPack machine can be stretched up to an incredible 70%. Typically this means that film savings between 10 and 50% can be achieved. This is a new innovative way of optimizing current automated packaging lines.
A lot of customer dialogs on Ligna were also centered around how to automatize a packaging line in the first place with this new innovative way of packaging. The feed-back during the exhibition on the typical ROI times experienced by our current customers, indicated the vast cost saving potential our future customers are expecting to realize when investing in the RoRo StretchPack solution.
We thank all of the visitors for their genuin interest in the new generation of horizontal packaging machine.
