Division profile
Systems to manufacture blown film have formed part of ALPINE's product range since 1955.
The reliability of these film blowing lines is well known, just as are the long years of experience we have had in the design and manufacture of such complex production equipment.
Our three testing centres - in Augsburg, USA and Japan - are equipped with state-of-the-art machines and components, and are used for both customer and development trials. Test series using the laboratory equipment can be carried out under as-real conditions so that the results fully reflect Alpine's capabilities.

Globally, blown film lines have become a mass product, for which there is high demand in diverse areas of application. The increased variety of products, as well as the growing production quantities go hand in hand with increasing quality requirements. The Reifenhäuser product program for blown film extrusion lines meets all these demands, thanks to the innovative components and overall concept.
Areas of application
The range of applications of blown films produced on Reifenhäuser lines
is huge. Antistatic films, stretch films and protective films are used in the automotive and electronics industries, for example. In the field of industrial packaging, shrink hood films, stretch hood films and heavy duty sack film are manufactured on Reifenhäuser lines. A remarkably wide product range include films for the consumer goods industry, fine shrink films, pallet wrap films, furthermore it includes laminating and adhesive films, as well as barrier films. Lines for agricultural products, such as crop forcing, cover and silage films, as well as building protection films, have been a Reifenhäuser speciality for many years.

Corona treater model BHSN ( BOPP-PET industry).
The field of BOPP-PET film has always been for years a key-field for ME.RO. Only an history and a very long experience can allow you to manufacture treaters able to guarantee a complete reliability as these big producing plants require. It is not by chance that nowadays ME.RO can be considered the most important mufacturer for this application. This is demonstrated by the fact that the most important producers of BOPP film around the world have joined our technology to reach important treatment results with no stops of production for years.
MAIN CHARACTERISTICS:
- Web width up to 10.500 mm.
- Specific power (energy density) kept strictly constant during running.
- Special electrode design to give the best transfer of power on the film and to maintain it clean during running.
- Special electrodes in AISI 316 stainless steel able to heat expand without modification of the pre setted air gap (easy heat expand system).

Nor-Cal offers an extensive selection of commonly used quartz crystal feedthroughs, sensors and multi-channel monitors, cables, quartz crystals, accessories and replacement parts for use in semiconductor, optical and industrial thermal deposition processes. Custom feedthroughs are available with a variety of flanges in all sizes.
Our coating instrumentation products support one of the more popular methods of thin film measurement and rate control _ the crystal monitor, which utilizes the piezoelectric properties of a quartz crystal.
The electrical characteristics of the crystal, which is held in place by the sensor, change during deposition. Single sensors are generally used for short deposition runs, whereas, dual sensors allow for longer runs. Dual sensors require an airline to operate a pneumatic shutter which covers one crystal at a time. The sensor is either welded to the feedthrough or attached with connectors. Most sensors are available with cooling lines.
The application determines the correct choice of sensor. The sensor determines compatible feedthroughs and cabling. The chamber determines the appropriate feedthrough and flange. For application temps up to 150°C, electrical connection between the sensor and feedthrough is accomplished with a vacuum coaxial cable. A bakeable, one piece sensor/feedthrough replaces the standard in-vac cable with a stainless steel high-temp coaxial line for high temperature applications up to 300°C.

Extrusion line for Determination of Film Quality
Stand-alone extruder KE 30 with Film quality analyzer and FSR
The Film Quality Analyzer measures the transparency and optically checks the quality of blown or flat films on a laboratory or production scale. The instrument detects in-line and differentiates between
• black specks
• gels
• fisheyes
• holes
These faults are classified acc. to their type and allocated to size classes.
The film is assessed on the basis of the number of faults and their size distribution.
Evaluation is done automatically through a comfortable Windows® 9x or NT software.
All data are stored in a database and can be imported by commercial programs.

Advantages of PPC's Ion-Beam-Sputtered (IBS) Dielectric Thin Films
--------------------------------------------------------------------------------
Durable, dielectric thin films are easy to clean and chemically resistant
Dense, non-porous structure is insensitive to moisture
Low scatter and absorption losses result in high-damage thresholds
Repeatable, highly controlled process for precise layer control
--------------------------------------------------------------------------------
At PPC, we use ion-beam sputtering (IBS) technology because IBS is a repeatable and controllable process that results in dense, durable, high-damage-threshold thin films. Since the materials are directly sputtered onto the substrate, the process can be precisely controlled and easily automated so that films can be deposited with extremely high accuracy and repeatability.
Unlike conventional evaporative and ion-assisted films that have porous microstructures, IBS films have extremely densely packed structures that make them impervious to water vapor, resulting in an insensitivity to changes in heat and humidity, even in a vacuum environment.
Types of coatings that PPC does every day on standard or customer-supplied substrates:
High reflectors
Anti-reflection (ARs)
Beamsplitters
Polarizers
Partial reflectors
Dichroic mirrors
Non-polarizers
Low dispersion
Broadband dielectric

Thin film coating is a vacuum deposition procedure used to enhance the transmissive properties of an optical surface. The most common types of dielectric coatings are anti-reflection and high reflection coatings, but beam-splitter, band pass filter, edge filter, and polarizing coatings are also available. Because thin film coatings are more durable than optical glass, coatings also help protect an optic surface from scratches and the environment.
Optimax produces optics up to 300mm in diameter with a wide variety of narrow and broadband anti-reflection coatings including doublet interface coatings. Both metal and dielectric mirror coatings are also available. For custom coatings, we utilize TFCalc thin film design software. Please see the reverse side for sample reflectance curves.
Optimax performs test runs of all coatings before beginning production to ensure a good design. We use a Perkin-Elmer Lambda 900 Spectrophotometer to check the performance of the coating upon completion. Adhesion, abrasion, and humidity tests are available to verify coating durability in accordance with sections of MIL-C-675C, MIL-C-48497A, and MIL-C-13508C specifications. Laser damage testing is also available upon customer request.
