In mid September, Tub-ex, Pro-ex og Rævhede Naturprodukter invited meat producers, chefs and other interested people from our network to a big eye opening event at Agro Food Park in Aarhus.

During the last year, our three companies have been working intensely on a new maturing technique under a project called OMHU.

OMHU is a visionary food project supported by EU funds under Future Food Innovation and also supported by the knowledge and experience from Professor Jorge Ruiz Garrachal from Copenhagen Universitity and Dieter Gravesen from ISI Food Projection.

The focus of project OMHU is a technique is called Tublin QCP (Quality Curing Process) which refers to the maturing of meat in Tublin bags.

More than 60 Danish stakeholders attended the event, and we were pleased to discover that the feedback on this project was extremely positive. We expect to be able to present a full university report by the end of the year including proof of concept.

Tub-ex’ Rilsan bags used for testing Amazon forest soil

How do undisturbed forest soils in the Amazon basin react in comparison with post-forest land cover ones?

The Brazilian-German research project EcoRespira-Amazon tries to understand this by determining soil to atmosphere gas fluxes and by intense soil geochemical analyses.

The environment is harsh and demanding, and all equipment is put to the test.

Soil sampling (auger-based) and transport is done with Rilsan bags because of their impressive durability, ultra low migration and highly reliable handling, securing the samples in the best way possible.

New product development
Public Date: 10/03/11
Tub-Ex has developed a special kind of breathable film for a company,which has invented a special range of “cushion” like products for the medical sector.

Decumed has invented a whole range of different products, which are used in the medical sector to avoid bedsores. The two inventors behind the company – Lars Bak-Christensen and Jens Ulfeldt approached Peter Schou at Tub-Ex some years back to ask, if some kind of cooperation could be established.

 At Tub-Ex we are always open to new challenges and Peter Schou developed a new film, which could fulfill the requirements by the inventors. The products are designed and sold by Decumed, but Tub-Ex works closely together with Decumed in the development and production of the products.

 On February 25th. 2010 many regional medias learned about the cooperation, and Decumed and Tub-Ex were invited to tell about the products and the cooperation in regional radio and news programmes – and articles were printed in severeal on-line and written medias. Even though all the links are in Danish – you can still get an idea of what the products are like here:

Ringing of casings
Public Date: 10/02/09
We can ring your shrinkable casings in calibres from 35 to 85 mm.
(equal to lay flat size 35 to 120 mm).

Tub-Ex has a unique coiling/ringing system. Instead of “ringing” we have chosen to call our process “coiling” as our process is very different from normal ringing process.

Our process gives a higher stability of the coil and a much lower percentage of loss. Using the HT system, you might even gain metres for some casing types.

A loss of material of up to 10 to 20% is the norm in the ringing process depending on the type of casing, but with the HT-coiling system, we have managed to achieve uo to 8% gained meters compared to the usual loss.

Please contact Tub-ex for futher information.
