XL Power enables up to 19 m long packaging and increases packaging speed

Tentoma introduces a new
XL Power packaging machine

The new XL Power packaging machine enables 6-sided sealed packaging of up to 19-meter-long products. For packaging of shorter products, XL Power can stretch film for even more products per packaging cycle, which increases the packaging speed. The first XL Power is already built and sold to replace an orbital wrapper. It is for a packaging line at a production site, where it will pack panels in varied sizes, all the way up to 13.5 m in length. 

Designed for stretching even more film

XL Power have more forces for stretching film. It means that XL Power can load and stretch even more film on the gripper arms during the packaging process. It opens opportunities for more packaging improvements. Most obvious is the increased maximum length of the products, which now can be packed and protected by 6-sided waterproof packaging. Depending on product shape and film thickness, it is now possible to pack and seal products up to 19 meters long. It is an increase in product length of 50%1), compared to the standard RoRo StretchPack® XL machine.

XL Power increases packaging speed by up to 25%

Another benefit from XL Power is increased packaging speed. The ability to load and stretch even more film on the gripper arms increases the packaging speed when using the “Semiflow packaging” principle. “Semiflow packaging” enables the packaging of multiple products in a row before the machine needs to load more film on the gripper arms. XL Power can load and stretch even more film on the gripper arms, so it is possible to pack even more products in a row compared to the XL machine. A comparison between XL and XL Power shows that when the XL machine packs 210 products per hour, the new XL Power machine packs 260 products. It means an increase in the packaging speed of est. 25%2) when using XL Power.

Technical speaking, the new XL Power is a reinforced version of the proven RoRo StretchPack® XL packaging machine. The main improvements on the XL Power machine are:

  • It is equipped with stronger and longer gripper arms to load more film.
  • The motors have become more powerful to stretch even more film.
  • The steel construction has become stronger to withstand the increased tensile forces. As all the RoRo StretchPack® machines, XL Power will be adapted to the production line and the specific packaging requirement.
1) ex. 60 μ film, 5% stretch => XL: 11 m > < XL Power: 17 m
2) ex. 60 μ film, 5% stretch, product length 1200 mm
The main improvements on the XL Power machine are stronger and longer gripper arms to load more film, more powerful motors, and the steel construction has become stronger to withstand the increased tensile forces.

DYKA orders RoRo StretchPack® for packaging of 10-meter pipes

DYKA Group, a leading European manufacturer of pipework systems, has ordered a RoRo StretchPack® packaging solution from Tentoma A/S for packaging of 10-meter long pipes. It will be installed in mid-2022 at the production site at Steenwijk in the Netherlands.

The main reason for this investment is that DYKA wants to improve the protection of its products against dirt and UV light, to ensure that both the quality and appearance are perfect when the pipes reach customers. The new packaging solution will also make it possible to have the DYKA logo nicely branded on the packaging film. It is not possible with the orbital wrapper, DYKA is using today.  

Using RoRo StretchPack®, DYKA will pack up to 10-meter-long plastic pipes horizontal into a UV-resistant stretch film tube. The film tube will be sealed in both ends for 100% protection against dirt, water and UV light during storage and transportation. The stretch film also ensures tight and uniform packaging while it will minimize film consumption.

New door packaging line provides 100% sealed packaging

Core plug applicator

Tentoma has now introduced a full RoRo StretchPack® packaging line for 6-sided sealed door packaging. The new packaging line includes the following functionalities dedicated to the door manufacturing industry:

  • The door is lifted for mounting corner protection
  • The door is centred on the infeed conveyor
  • The door size is measured (width x height)
  • The door is packed and sealed in one operation

Using RoRo StretchPack®, the door is packed in a tubular stretch film. It provides a 6-sided packaging, with a short 100% waterproof sealing in each end. It protects the door against the penetration of dirt and moisture during storage and transportation.

“We have seen more door manufacturers shifting to use RoRo StretchPack® for packaging,” Jane Tønder says. She is Head of Sales at Tentoma, who has developed the RoRo StretchPack® technology. She continues:” That is the reason why we have developed this complete packaging line  to the door manufacturing industry. It can be installed as a standalone solution or as an inline solution in a fully automated production line. The final configuration will of course always be based on customers’ requirements”.

Core plug applicator for packaging of rolls

Core plug applicator

Automatic insertion of core plugs in rolls using a core plug applicator is now an option for the RoRo StretchPack® packaging machines.

The RoRo StretchPack® packaging machinery has become popular and especially for packaging of nonwoven rolls. The reason is that the horizontal packaging of rolls in a seamless tubular stretch film provides a 100% waterproof and uniformed packaging. It is clients within the nonwovens industry who has requested to include a core plug applicator in the packaging process.

The new plug applicator can insert core plugs in rolls with diameters up to 1400 mm. The diameter of each roll is measured automatically to ensure that the core plug is centred. The applicator has a magazine for 100+ core plugs. This way you can take advantage of the high capacity from a fully automated packaging line without any bottlenecks.

XPS | EPS | PIR | PU – Packaging Machines

Packaging machines for structured insulation panels such as XPS, EPS, PIR and PU have for years been dominated by energy consuming heat shrink systems. This is changing now since new and energy friendly alternatives have proofed to be a strong alternative. There are convincing evidence that manufacturing companies are also eager to benefit from other advantages like high waterproof packaging, high repeatability and low plast film consumption.

  • Film consumption savings (typically between 20-60% in volume corresponding to 10-50% in cost savings) in comparison to heat shrink system solutions
  • Waterproof packaging (this has been tested by e.g. Saint Gobain in their climate chamber test before they invested in our machinery for glass wool where absolutely no water can enter)
  • Better branding (also on the sides)
  • Smooth packaging with better look and feel with high repeatability
  • Energy costs savings
  • Film can be delivered locally (Tentoma does not deliver film but has a range of approved suppliers and others can be approved as well)
  • UV blocking/protection possible with the film
  • Film strength: If your customer has double packs (600+600) in his packs then he will be able to lift and manoeuvre the packs after packaging with RoRo StretchPack

For other products and dimensions please check out the possibilities in this video.

Tentoma product dimensions

Product Dimensions

Structured insulation panels can have various dimensions. Consult with Tentoma to define the exact machine that can cover your product dimensions. The following span of dimensions can be covered.

Product Dimensions

W:          600, 1200 (including 600+600) Max width is 1350 mm

L:            Max 8000 mm

H:           Max 1400 mm

Packaging Capacities

In order to reach industry required capacities the machine series Duplex and the SemiFlow function is required. The SemiFlow function is briefly explained a multiple packaging sequence function where no time is wasted during the packaging process. The film being prepared at one of two film stations is sufficient to cover a series of products. This reduces the time spent going back and forth between film stations and packaging position at the conveyor.

  • Total of 12 km film available (40 micron)
  • Printable film
  • Protection of L-shaped products
  • Corner protection (film pressure on corners in can be controlled)
  • High seal strength and stretchability (particularly important if 2 board layers per pack (600+600)
  • UV protection of film and product an option
  • At the final customer: Film is easier to remove from product, easier to minimize and occupy less space than heat shrink film on a construction site (roof area)

Energy Consumption Savings

A RoRo StretchPack machine of the type above will consume between 4,5 and 5 kW/h during operation. During ramp-up and ramp-down there is no energy consumption. In comparision to heat shrink systems there is a significant energy consumption saving during full operation, during production stops and during ramp-up and -down times. Energy consumption in heat shrink systems is typically 40 kW/h excluding ramp up and down times. In addition: The fire insurance costs can be reduced!

Energy Consumption Savings

ROI – Customer Example

Our customers (when comparing to Heat Shrink Systems) typically see a film consumption saving of 20-60% which corresponds to a film cost saving of 10-50%.
An XPS customers with full year production has calculated a return of an investment of 1,3 years including a capacity increase of 20%. The yearly cost savings amount to 200.000 Euro compared to an existing heat shrink machine. The major costs saving points are film saving (154.000 euro) and energy saving (36.000 euro) and the maintenace saving of 6.200 Euro. Then of course the packaging quality is higher due to a complete control of the packaging film.

Naue Geosynthetics Invest in RoRo StretchPack Machine

The leading manufacturer of geosynthetics in Germany called NAUE GmbH & Co. KG has invested in an XL-S2 machine from Tentoma A/S. The purpose of waterproof packaging for high-value geosynthetic rolls has been a key driver in choosing machinery from Tentoma.

Another driver was to implement a fully automated packaging process in an existing production set-up with limited floor space. The full RoRo StretchPack machine portfolio is characterized by occupying minimal space in the machine length direction. This makes it possible to integrate the machines in existing in-line and off-line packaging areas in an easy way.

NAUE – A RECORD OF INNOVATION:

  • NAUE GmbH & Co. KG has been part of the history of geosynthetics since the very beginning;
  • NAUE introduced the first nonwoven filter material for use in hydraulic engineering applications;
  • Those products are still fully meeting their designated purpose today – for example, on the embankments of the Mittelland Canal, the only East-West waterway in Northern Germany;
  • NAUE of today became an independent company in 1984 under the name of Naue Fasertechnik GmbH & Co. KG.;Tentoma Naue geosynthetics packaging

Geosynthetics | Geomembrane | Geotextile

Product protection of rolls   

In this chapter, you will see more examples of the packaging of rolls. But first, let’s look at some of the typical problems we experience that Geotextile manufacturers are struggling with today:

  • Seals on the length of the reels and the ends are opening;
  • Water comes in the reel;
  • The film needs to be as slippery as possible on the outside for storage reasons;
  • Labels don’t stick well on the sides of reels, because of “folds” in the film;
  • Film tears when handling in-stock situations;
  • Branding is not satisfactory;

How to solve Geosynthetics | Geomembrane | Geotextile packaging problems?

Here are some examples of what is possible to solve with the RoRo packaging technology. Watch these 4 examples:

Eye-to-Sky

Horizontal stretch packaging item 10 - Cloth / Tissue material (must be kept moist)
Cloth / Tissue material (must be kept moist)

Example 1

Example 1 is from a customer in Spain that has requested to encapsulate 100% the product. The reason is that the cloth needs to maintain a controlled state of moisture level.

Note: Quite the opposite really of what is normally the task in packaging. With RoRo you can keep moisture in or out.

Example 2

Example 2 is not only to show a potential customer that the rolls are 100% tight but also to enable a test of:

  1. Film has high enough tear and puncture resistance to withstand normal logistic handling of geotextile rolls
  2. Insertion of plugs in the end while ensuring 100% tight packaging

Product Protection of Outdoor Stored Products   

Outdoor storage of products is a topic Tentoma is receiving positive feed-back since the high quality film material applied in RoRo machinery allows safe outdoor storage of up to 24 months.

The film can be specified with UV protection and UV blocking in order to protect the film and the goods.

Besides protecting the goods from moisture, contamination, dust and alike the film also has excellent capabilities in being a low-friction film. When products are stored tightly together (e.g. geotextile rolls) it is a requirement that the film doesn’t get damaged when placing and removing the products.

Easy transport due to low friction between goods and thus no sticking

  • How to exchange a 500 Kg. film roll in 2-4 minutes
  • Packaging material savings
  • MMI – Man Machine Interface (Standard and detached control system)
  • Tentoma scope of supply

Reduce Film Consumption

Tentoma can assist in reducing packaging material consumptions. When calculating and performing test packaging you typically reduce the consumption with 20-60% leading to a cost saving between 10-50%. Additional cost reductions can be realized and in general we see consumption savings related to:

  • Heat shrink film
  • Going from manual to automated packaging
  • Reduce film material waste compared to heat shrink, manual packaging, orbital wrapping
  • Optimize thickness and stretch percentage depending on the product
  • Open ends / closed ends
  • Eliminate or reduce cardboard
  • Removal of polyethylene bags (manual or semi-automatic packaging)
  • Optimal use of perforated or micro punctured materials
Vertical stretch hooder machines
Global film suppliers for Tentoma RoRo StretchPack machines are equal to those supplying film to vertical stretch hooder machines.

Each LD PE-film can contain 3-5 kilometers of film which means low film roll exchange frequency.

Which Packaging Machine to Choose?

The RoRo machines all apply the same packaging technology and the selection of an appropriate machine will depend on mainly 3 things:

  1. Product dimensions;
  2. Required packaging output/cycle;
  3. Product variance;

Ad 1 - Product dimensions;

Products within e.g. wood (wood blocks, wood building materials, furniture, panels, tables etc.) and within rolls geotextile, geosynthetics, geomembranes, geo fabrics) can typically be covered within the max 8-meter length that is possible with RoRo machines. The maximum height is 1,4 meters and the width is 1,35 meters.

Dimensions

 

Ad 2 – Required packaging output /cycle;

The packaging cycles of the Simplex XL machine series are fit to cover most output challenges. So, a wood block of e.g., 6 meters, 0,6 meters high and 1 meter in width can be packed with a cycle of <65 packs per hour based on the length (follow the red arrows in the figure below.). See the cycle information here for XL-S2.

Machine dimensions and packaging capacity

Ad 3 – Product Variance;

An often-asked question when we get involved in a new packaging project is: How can the product variance be covered?

The versatility of the RoRo machines makes it possible to cover a variance of products. One film roll can as a starting point cover various product dimensions since the film can be stretched from 0% to e.g. 75%. Products that can fit into this range can be packed with this same film roll.

Frames

Now, products outside this range will then need to be covered by a second film roll with other dimensions meaning that we are in S2 solution mode. If this is not enough, we can apply 3 different dimensioned film rolls.

Step-Change in Stretch Hood Machine Design 

The founder of Tentoma, Frank Bruhn, has a long track record as a service technician at a leading manufacturer of vertical stretch hood machines. This know-how was extended to other vertical stretch hood brands when he started his own technical service company with global reach.

He noticed that the same problems occurred frequently, and this vast know-how was key when developing the new generation of packaging machines based on already proven key technological elements back in 2010. The goal was to eliminate the weak elements he experienced with the vertical stretch hood machines.

Step-Change with RoRo Machine Design

  • Opening wedge without any moving parts (avoiding suction cups, etc.);
  • Belts and no roller chains (which require maintenance);
  • Few moving parts;   
  • Standard and acclaimed components used (SEW, SICK, FESTO);
  • PLC: Siemens Serie 1500 with safety module integrated (programmed in TIA portal);

Product Protection of Outdoor Stored Products  Packaging of H+H products

Tentoma is receiving positive feed-back on the RoRo machines because of the outdoor storage capability of the packed products. The high-quality film material applied allows safe outdoor storage of even up to 24 months. The film can be specified with UV protection and UV blocking in order to protect the film and the goods. Besides protecting the goods from moisture, contamination, dust and alike the film also has excellent capabilities in being a low-friction film. When products are stored tightly together it can be a requirement that the film doesn’t get damaged when placing and removing the products.
