In our pattern construction process, we use CAD technology. This enables us to guarantee that the dimensions and design of the special bag will match the prototype when it goes into series production. This applies regardless of the type of bag, whether shoulder bag or document bag, work bag or toiletry bag.
Modern cutting technology with CAD enables cost-effective production of special bags: The time-consuming production of punching knives is no longer necessary. Changes to shoulder bag, etui or presentation folder can easily be incorporated into the production of the next series.
Equipped with innovative sewing technology, we manufacture your technical bag. With our sewing machines and sewing field automats, we can fulfil special requirements for bartacks and seams stitch by stitch with pinpoint accuracy, regardless of whether emergency backpacks and bags or small modular systems are being produced.
In order for a seam to be watertight, such as in the emergency cases used in water rescue, it must be sealed using a tape machine after sewing. The elasticity of the material to be sealed and the heat setting play an important role here. We have different types, colours and textures of tape to use for our various emergency backpacks and bags.
We use high frequency welding technology to manufacture waterproof bags, such as courier bags and bicycle bags. With this technique, the parts are joined together by applying high frequency energy in the form of an electromagnetic field and pressure. The right mix of pressure, welding and cooling time ensures a perfect result. We mainly process PVC and PU as the base material for special bags.
Ultrasonic welding technology is used in our AEROcase® – EMS+ Series. This technology produces seams without punctures and the welded seams are therefore very easy to clean and disinfect. This is particularly important for our PROpack - Emergency Backpacks and our PRObag - Emergency Bag, considering the EASY Clean hygiene concept, which are used in the professional emergency medical services and where special hygiene is essential.
We offer our customers customized finishing techniques for their special bags. This allows companies to apply their logo to shoulder bags, backpacks, belt bags or presentation folders. Whether digital printing, sublimation printing, thermal transfer printing or woven labels: together we will find the perfect solution for your product to ensure that your company is recognised on the textile product.
Digital printing makes it possible to print photos or other multi-coloured motifs in brilliant quality on shoulder bags, crossbody bags, travel bags or etuis. The prerequisite for this technique is a material that is as smooth as possible, which is why we like to use this process for bags or cut parts made from truck tarpaulin or film.
Our technology for applying single-colour logos to special bags: In thermal transfer printing, a film coated with temperature-sensitive ink is passed between the material to be printed and a thermal print head. The print head becomes hot, the colour layer in the foil melts and is transferred to the material. The result: an exact colour print with precise print quality. We use this process for nylon and polyester bags.
With this technique, we can print cut parts made of white materials, such as polyester, realistically and in any colour. White fibres do not distort the printed image. Printing on coloured plastic is also possible but leads to slight deviations. In sublimation printing, the motifs are first printed on paper and then pressed for around one minute. This allows the ink to penetrate deep into the fibres of the fabric and there are virtually no limits to the creativity of the motifs.
Embroidery gives a bag a look and feel – regardless of the fabric it is made of. This type of finishing allows logos, entire lettering or motifs to be placed. Many shoulder bags, writing cases or transport bags are enhanced in this way. We use one or more threads for embroidery.
We insert black woven labels, often called “woven flags”, into the outer seam. This gives each emergency backpack and each of our bags – from our PROpack to the FirstAid Bag and the WASHbag –an additional standardized design detail.
All textile products sold in the European Union must be labelled. This applies to all products that contain at least 80 percent textile fibres by weight – including, of course, our emergency backpacks and transport containers. Our textile labels are sewn into the inside of the bag and provide information on article numbers, lot numbers, addresses and contain care symbols.
Rubber badges or rubber labels are patches made of plastic or rubber. They are usually provided with a sewing channel on the edge for sewing on the badges. These accessories serve as eye-catchers for shoulder bags, tool bags, bicycle bags, doctor's bags and many other special bags. Rubber badges are very durable and weather resistant.
The processing technology used for your technical bags depends on the requirements of the product in question. For example, a bicycle bag has to fulfil completely different criteria than a belt bag or a holster. We determine the processing techniques together with you in advance of the production process.
