Today the Walter Widmann GmbH now already is an exempt private company in that 3. Generation.
Our grandfather, Walter Widmann created that enterprise at the beginning of the thirties metalworking at that time.
In the fifties the core business producing by lathe was main, from bearing bushes and similar parts.
But in the beginning of the sixties the first experiences in the plastic injection molding technology were already gained on the legendary ARBURG C4B machines.
With the rapidly progressing development of the plastics engineering, also our enterprise grew up to a competent supplier of technical plastic parts.
A milestone was the development and patenting of our wire feeding units end of the sixties. With this technology completely new fields, which constitute the most important support leg of our enterprise up to the today's day, opened.
The wire feeding units are adapted constantly to most modern machine engineering. Together with our tool technology individual bending, coining/shaping and a moldong-in of wires in one single processing step is possible.
A philosophy of our enterprise is to attain a maximum of quality and customer satisfaction by continuous improvement of all our processes.
We are certified according to DIN ISO EN 9001/2000.
A guarantor for competence and know-how are our coworkers. Some of them accompany us already over decades and did also their training with us.

Founded as partnership W+B Linder, our company started in 1950 as specialist for steel wire and wire products. In the very beginning, bottle stands for the beverage industry were brought to market - being replaced later on by plastic boxes. Bottle stands were followed by cardboard stitching wire - at first in small rings, later in up to 1,000 kg coils.
The quite rough carton stitching wire was one, the fine bookbinding wire the other field of activity in that time. The sale of binding wire, used for securing parcels, can also be considered as starting point of our activities in the strapping business that became our biggest pillar in our product portfolio quite quickly.
Later on, packaging wire was replaced by PP strapping, representing the nucleus of the plastic strapping specialist LINSTRAP. PET strapping were added subsequently and made replacement of steel strapping in many industries possible for the first time. PET strapping has the advantage of being less expensive (~ 60% less than steel strapping) without the risk of damaging the packaging good due to corrosion or sharp edges. In addition to extruded plastic strapping, polyester textile strapping also became part of the product programme – at first only as hot melt strapping, later on as woven and composite strapping as well.
As consequent further development of woven strapping, LINSTRAP added one-way lashing belts to its product range. That kind of lashing is mainly used by export packaging companies. With the Lash HD, a lashing tensioner was launched setting new standards in terms of possible tension force, massiveness and price.
In 2011, SeeveTEC joined us as specialist for strapping machines, carton sealers and erectors as well as conveyor technic. SeeveTEC started as small engineering office, they designed packaging machines for other companies and started producing under their own brand in 2009. Thanks to a European network of technicians, a 24h service can be offered to all clients buying directly from SeeveTEC.
After the foundation of W&B Linder in 1950, the renaming in Draht-LINDER Seevetal in the year 1991, now in 2011 we see the big merger of Draht-Linder, LINSTRAP and SeeveTEC to the new entitiy "LINDER GmbH", that will move in the new company buildings in Seevetal in the same year: With our new central warehouse with more than 5,000 m², we make sure that our customers will get their goods even faster and more flexible than today. We are looking forward to being your reliable partner also for the next 60 years in the field of "strapping - binding - stitching"!

LINSTRAP is THE specialist for plastic strapping in the LINDER Seevetal brand network.
Many industries are gradually switching from steel to plastic strapping. This is mainly due to the following advantages that plastic strapping offers:

• No risk of corrosion
• Significant price advantages (up to 50% compared to steel strapping)
• Minimised risk of injury to people and packaged goods

Plastic strapping can be roughly divided into three categories:

• PET strapping
• PP strapping
• Polyester textile strapping

The following questions help to answer the question which type of strapping is the right one for the respective application:

• How often is strapping required?
• What strength is required?
• Does the volume of the packaged goods change?

The highest strength values can be achieved with PET and polyester textile strapping. If strapping is required frequently, PET strapping is preferable, as it can be processed very efficiently - with battery-operated strapping tools or fully automatic machines. For smaller quantities, the investment in these devices is usually not economical, so that textile strapping should be used here.
If only low strengths are required, PP strapping is often the best option - especially since very inexpensive strapping tools are already available here.
If the volume of the packaged goods changes, e.g. when wood dries or bulk goods settle, PP strapping is recommended due to its high elongation or, alternatively, textile strapping due to the possibility of re-tensioning the strap. For strongly expanding packages, such as foams or baling presses, straps with lower elongation are preferable.
