Successful Projects – Examples from the Field

  • E-bike drives: Well Protected and Perfectly Marked

    Brose as the world’s fourth-largest automotive supplier in family ownership has transferred this know-how to e-bikes and designed an innovative drive system for electric bicycles. Brose applies the high quality standards of the automotive industry to e-bike drives as well.

    Effective Protection against the Elements
    The demands made on marking as well as tamper protection and anti-counterfeiting solutions for these electric motors are high as well. “In addition to retaining their visual appeal during their entire life, the labels must be UV- and weather-resistant, and withstand mechanical impacts such as gravel on the road,” says Brose. Specifically for these demands, the experts from Schreiner ProTech developed three different solutions: A label with a protective overlaminate effectively displays the manufacturer’s logo and optimally protects it against external influences. The second label is a nameplate which, in addition to marking the product, enables it to be authenticated by means of a complex, tamper-evident checkerboard film that is difficult to counterfeit. Furthermore, a housing closure seal with security slits on the e-bike motor reliably indicates potential tampering attempts.

  • Nameplate with venting function

    SICK produces sensors that have to resist numerous environmental influences such as major temperature fluctuations and the effects of moisture in target applications. To vent such housings while maintaining ingress protection according to their IP code and to mark them, Schreiner ProTech has developed a nameplate that is provided with a pressure compensation seal (PCS).

    Marking and Venting Combined Nameplate with venting function

    Temperature fluctuations may result in excess pressure or vacuum in electronic housings. Pressure differences stress the assembly components and their individual elements and may cause damage resulting in the destruction of the electronic system. A pressure compensation seal regulates this pressure by means of its membrane and at the same time provides protection against external influences such as water or dust. For the sensor housing of a driverless transport system (FTF), SICK was seeking a solution for venting and marking, and opted for a pressure compensation seal from Schreiner ProTech. The solution saves a lot of space because marking and venting elements do not have to be installed side by side. The processing of the pressure compensation seal and nameplate in a single pass saves process times.

  • Documentation of Repairs: Serialized Marking Solution

    Schreiner ProTech has developed a plastic clip with laser-engraved code and human-readable text, as well as two silver-colored labels made of Color Laser Film (CLF) for the Bosch QualityScan. As the world’s leading manufacturer of diesel injection systems, Bosch attaches major importance to top-quality repairs. Therefore, in the Bosch QualityScan, the company is now offering garages and consumers transparent web-based documentation of common rail component repairs by authorized garages. Schreiner ProTech supplies the elements for respective proof.

    Two Solutions from a Single Source
    “As a result, we’re receiving exactly the two solutions we need from a single source,” says Dirk Schoenfeld, Engineering Project Manager Automotive Aftermarket at Bosch, commenting on the innovative proof of quality. Account Manager Axel Müller from Schreiner ProTech explains: “By using our proven Color Laser Film and the new development for laser engraving the plastic clips, we were able to successfully achieve a solution for two different requirements.”

  • Avalanche Transceiver: Pressure Compensation Seal Protects Electronics

    Devices used to search for avalanche victims increase the victims’ chances of survival many times over. The “Barryvox” high-tech tool by Mammut makes it possible to precisely locate several people due to highly complex electronics that have to resist harshest ambient conditions. Adequate electronics protection is provided by a rugged housing for which Schreiner ProTech supplies the pressure compensation seals (PCS). They ensure venting of the transceivers and prevent moisture ingress.

    Functional Component for Protection against Excess Pressure and Moisture
    Pressure compensation seals prevent excess pressure in the electronic housing and, at the same time, are completely impermeable to water due to a special membrane. “The membrane resisted our load test, which simulated a dive in an alpine brook”, says Ilari Dammert, Product Manager at Mammut. As a result, users can be assured that the transceivers also work in heavy snowfall, rain and wet conditions.

  • Tachograph: High-security Seal Protects against Tampering

    Schreiner ProTech, together with Continental, has developed high-security seals that indicate attempts to tamper with tachographs by opening their housings at first glance. The seals combine a Void Effect, Hologram and sequential numbering

    Visible Tampering Protection Thanks to Seals
    When police officers or customs officials conducting routine checks suspected that drivers had not taken their mandatory breaks or spent more than the legally permissible time behind the wheel in the past, they had to perform complex examinations of the tachographs for potential tampering attempts. Tachograph housings consist of two parts that are closed with a screw. This is the weak area that allows people with criminal intentions to tamper with the device. The seals are placed precisely on top of the screw and the connecting edges of the housing parts. They immediately indicate if someone has tampered with the tachograph.

  • RFID Special Development: RFID Label (UHF) with a 4K Chip(UHF)

    Schreiner ProTech, together with Siemens, has developed a new RFID label (UHF) with a 4K chip (4KByte) for Siemens’ new Simatic RF600 reader generation. The 4K chip offers 53 times more storage capacity than conventional RFID solutions. This capacity is required for complex processes in manufacturing control. In addition, manufacturing-relevant data is stored on the product or transport container in the automotive sector and in the process industry.

    RFID Including Process Know-how
    The technology corporation had three reasons for selecting Schreiner ProTech as its development partner: industry-specific process knowledge, specific know-how in manufacturing RFID labels, and knowledge of potential suppliers and cooperation partners.

  • Packaging of Plastic Vials: Breathable Container Closure

    Re-sealable, dirt-repellant, air-permeable: Intelligent protective films often have to perform several functions. For a renowned biotech company, Schreiner ProTech has designed a special product solution which is breathable and thus prevents the packaging of plastic vials from bursting while being shipped as air freight. At the same time, the innovative cover protects the sensitive vials again dust and dirt.

    Fully Automatic Processing that Includes Venting
    The customer applies the Protective Film on a dedicated packaging line in a clean room environment. Fully automated processing of the material ensures reliable sealing of the blister packs. Thanks to the venting function of the Protective Film, the blister packs sustain no damage during air shipment and hygienic handling of the vials is assured.

Certified Quality on the Highest Level

Quality management is one of Schreiner ProTech’s top priorities. It is guaranteed by certifications which entail periodic review of compliance with quality standards by independent auditors.

In line with IATF 16949 certification, Schreiner ProTech practices systematic quality management on the highest level, directly aimed at a constant and reliable production and delivery of high-quality products.

The Right Solution for any Challenge

  Marking, Labels and Nameplates
Kennzeichnungsetiketten von Schreiner ProTech

Customized labels mark various products, make it possible to identify them, and allow for careful documentation of a variety of actions and processes – for instance when installing technical elements in cars.

From single- to multi-layer composites, from analog to digital printing techniques, as colored or monochrome versions, due to a large material mix and diverse machinery, Schreiner ProTech meets practically any customer requirement.

PreScript labels are marking solutions which are pre-printed with all the desired data. PolyScript labels on the other hand provide space for customized subsequent printing using TTR or inkjet printing techniques at the customer’s site. Variable text, numbers or codes are printed, generated and managed as required as well.

Challenges include difficult substrates, harsh environmental influences or labels that are subject to official approval.

Our Pre-Polyscript product demonstrator visualizes the various elements that can be integrated into a parts marking solution.

Examples of the various fields of application and related system solutions can be found here:

  RFID and NFC

RFID (Radio Frequency Identification) refers to a technology that enables data identification via radio without visual contact. There are three main applications where RFID labels for product marking make sense: if it is essential that data be gathered quickly, if there is no direct visual contact with the label or if the label is at risk of becoming illegible during its service life due to environmental influences.

As part of RFID technology, NFC (Near Field Communication) is tailored to mobile readout via smartphone and allows interactive labeling.

  Brand Protection

Customized marking labels and system solutions offer reliable and efficient authentication, tamper evidence or track & trace options for products and documents, as required. 

  Laser Films

Color Laser Film (CLF) is superbly suited for creating self-adhesive nameplates and nameplate sets on Nd:YAG, vanadate and fiber laser systems. The contactless laser marking process takes place inside the material composite underneath a transparent protective film. As a result, the marking process is emission-free and the nameplates are particularly scratch-resistant and durable.

  Ventilation of Housings

Electronics are not installed in an absolute vacuum but in a component surrounded by air. Their operation combined with external influences such as changes in temperature can result in excess or negative pressure inside the housing. Pressure differences heavily stress assemblies and their components, and may cause damage to the housing through which water or dirt may enter. A Pressure Compensation Seal (PCS) that equalizes pressure differences and, at the same time, ensures that neither water nor oils or fuels can enter the housing from the outside can be essential to the smooth operation of electronics.

The PCS product solutions from Schreiner ProTech offer:

  • Secure retention: fastening by self-adhesive coating or ultrasonic welding
  • High airflow rate for fast compensation of pressure differences between the housing and the environment
  • High water retention capability
  • High product design flexibility: PCS are variable in terms of shape, size, material and adhesive - customized solutions are possible
  • No mechanical fastening to the housing, eliminating the need to change the housing geometry
  • Low height < 0.5 mm
  • Packaging on rolls for manual or automatic application for ease of handling, integration into manufacturing line is possible

  Paint Mask

Paint mask films prevent contamination by paint of the area to be protected. By means of a starter tab, the protective films can be easily peeled off after the painting process. Multi-layer designs for repeated painting processes are available as well. 

  Protective Films

Dust, dirt, oil, chemicals and corrosion: General industrial and automotive components are processed, shipped and stored. This often entails exposure to harsh weather conditions and diverse environmental influences. Reliable protection is vital to ensuring impeccable processing and perfect performance of the products. The protection films from Schreiner ProTech cover components of various sizes, shapes and surfaces, either permanently or temporarily, which makes them an ideal solution for your products.

  Occupant Safety

Passive safety in automobiles thanks to functional labels: Labels for occupant protection encompass solutions for airbags, also known as supplemental restraint systems (SRS), in the car. The products are customized to suit any requirement, be they intended for frontal airbags, side airbags, knee airbags or head airbags. 

  Printed Electronics

Electronics in Film (EIF) are conductive printed or die-cut structures on thin and flexible film substrates that can conduct low current flows. EIF performs many functions of traditional electronic applications but offers a crucial advantage compared with conventional technology: low height of less than a millimeter combined with minimal weight, as well as high flexibility and bendability. For instance, this enables the integration of EIF behind exquisitely designed curved surfaces or into tight assembly spaces.

Fields of Application:


  • Flat and flexible film structure (approx. 50 - 300µ) with minimal weight
  • Flexible choice of materials according to specific customer requirements and adjusted to the respective application: conductive paste printing, die-cut parts from conductive films, e.g. copper- or aluminum-based
  • Transparent film substrates for functions involving transmitted light
  • Easy integration into the customer’s product due to self-adhesive coating of the film
  • Easy bonding with customer electronics by plug connections, crimping or conductive gluing possible

  Adhesive Bonding

Adhesion - guaranteed to stick! Adhesive die-cut parts from Schreiner ProTech are the solution to a wide variety of challenges in the field of joining and fastening. Pressure-sensitive adhesives clearly simplify and accelerate manufacturing processes, and additionally offer the following advantages:

Adhesive die-cut parts effectively and reliably join components even if they’re made of different materials. Uniform distribution of force across the entire length of the component prevents unilateral, isolated loads. Processing is clean and fast, without drying and curing times or trails of adhesive left on components, which eliminates related maintenance requirements.

Adhesive die-cut parts can even perform additional functions such as height, pressure and temperature compensation, protection, sealing or insulating. Suitable materials and geometries are selected and utilized by Schreiner ProTech according to the application - and may also be combined with an application unit from Schreiner ProTech.

  Label Application and Processing

Application and processing of specialty labels and customized product solutions should lend itself to perfectly smooth integration into existing processes. This requires appropriate equipment and systems as well as tailored connections.
