04/23/2018 – 04/27/2018
From 23rd until 27th of April, the worlds leading trade fair for industrial technology, the Hannover Fair, and the CeMAT 2018, fair for intralogistics and supply chain management, took place in Hannover simultaneously .
As part of the joint stand of the State of Lower Saxony, we had the opportunity to show our solution for minimization of packaging volume and filling material – the folding box volume reducer Vario 558. The visitors of our booth, including the Prime Minister of Lower Saxony Stephan Weil and his Deputy and State Minister for Economic Affairs Bernd Althusmann, were enthusiastic about the advantages our machine will bring for parcel shipping sectors and society.
Furthermore, we contributed a part to the smart Supply Chain shown on the Logistics 4.0 Hub at the CeMat: our half automatic folding box sealer with wet adhesive tape.
We thank the visitors of our booth for interesting conversations and the State of Lower Saxony for giving us the opportunity to participate in their joint stand.
03/13/2018 – 03/15/2018
From 13th until 15th of March OPITZ exhibited at one of the most important international trade fairs for intralogistics solutions and process management – the LogiMAT 2018 in Stuttgart.
Visitors of our booth had the opportunity to get a live impression of our automatic packaging solutions for industry and commerce. Showing our Volume reducer Vario 558 in process gave us the possibility to demonstrate the benefit of volume optimization of folding boxes by fully automatic measuring, cutting, folding and sealing.
Especially the flexibility of our machines met the visitors’ enthusiasm: OPITZ Volume reducers can process various ground formats at once, which is a unique feature in the market.
We thank the visitors of our booth for interesting conversations and a very successful LogiMAT 2018!
The entire developer and production team of Opitz is glad to gain 2nd prize with our product innovation “closing automatic machine for volume reduction” category 20 employees).
We are pleased to receive this award, which we regard as confirmation of our creative solutions for the market of packaging and also for the environment.
Further information about the product and the solution “volume reduction” can be found here.

Who would have thought that: tried-and-trusted wet adhesion technology is making a comeback. Traditional glue from the era of protective sleeves, counting houses and post counters still provides great benefits to internet-based mail-order businesses.
There is a good reason for that! Below we have listed the benefits of the wet-adhesion method for you. OPITZ has adapted this technology and has perfected it for building sealing systems. The wet adhesion sealing head, which we have developed in various respects, plays a key role in this process.
Please contact us. We will advise you – and you are likely to find this wet adhesion method exciting!
1. Theft protection
Only a wet adhesive strip can guarantee protection of the contents of the shipping box against theft. The adhesive of the wet adhesive strip penetrates into the folding box surface and creates a strong, wall-plug-like connection that is clearly visible and can only be separated by destroying the outer layer of the box. Wet adhesive strips are not sensitive to weather fluctuations, light exposure and ageing.
2. Drop tests Reinforced
wet adhesive strips have superior strength when compared to self-adhesive strips made of PP or PVC. The Fraunhofer-Institute for Food Technology and Packaging has performed drop tests at the request of the F.I.P.A.G.O. (International Association of Rubberised Paper Manufacturers) that clearly demonstrated their superior performance. A corrugated cardboard shipping box according to FEFCO 201-4070 was filled with bulk material (peas) to a total weight of 18 kg and dropped at 23ºC and 50 % relative humidity. The drop tests were performed according to DIN 55441 Sheet 1. The initial dropping height was 80 cm.
4. Box sealing with wet adhesive strips is economical.
Wet adhesive tape will win a direct price comparison between equally sized rolls of self -adhesive tape and wet adhesive tape. The wet adhesive tape is the most cost-efficient alternative of all sealing systems, when all costs for machines, material, wages for automated closing of the packaging units, etc. are considered – e.g. for a volume of 2000 units per day.
5. High tear propagation resistance of wet adhesive strips
Adhesive plastic strips have no tear propagation resistance; as soon as the edge is damaged, the whole seal tears extremely easily. Fibre-reinforced wet adhesive paper strips, on the other hand, have high resistance against tear propagation, due to embedded glass fibres, so that the fibres keep the box closed even after the paper layer has been completely broken.
Adhesive plastic strips have elongation-at-break values of 40 to 70%. When the strips are over-extended, the box flaps may open wide enough to allow loose content to pour out. Reinforced wet-adhesive paper strip shave elongation-at-break values of less than 4%, so that the box remains closed until it breaks completely, which requires high force, due to the fibre reinforcement.
Dust during filling and dusty box surfaces do not spoil the effects of bonding with wet adhesive strips. By contrast, dust significantly spoils the effects of the sealing process with contact adhesives and reduces the bonding capability of self-adhesive film.
Pulling the strip from the roll during manual processing requires no noticeable force, as wet adhesive strips only become adhesive once they have been moistened. Self-adhesive tapes, on the other hand, adhere to varying degrees to the uncoated side of the roll; force must be applied to process them, which may tire the staff involved. Wet adhesive strips run silently, while plastic adhesive strips make considerable noise. In extreme situations, this may require noise protection measures or at least personal hearing protection.
Wet adhesive strips have been standardised for decades (DIN 55475 and DIN 55476 Sheet 1 and 2). This standardisation will reassure even users who are not familiar with the technology with regard to quality and reliability.
10. Environmental acceptability
The raw materials for the wet adhesive strip – paper made of wood and starch-based adhesives made of potatoes – are natural products that are not scarce. Wet adhesive strips can be included in recycling processes without problems. Wet adhesive strips have been in use for more than eight decades. FIBEPA concluded that their use will continue as long as large amounts of folding boxes have to be closed in an economic and reliable way.
