Innovative Vapor phase Corrosion Inhibitor Films

At Cortec ® Advanced Films (CAF), in Cambridge, Minnesota, we specialize in manufacturing Cortec’s innovative Vapor phase Corrosion Inhibitor (VpCI ®) films and offer customers complete converting, extruding, printing, and compounding capabilities.

CAF manufactures films and bags according to customer specification in terms of product size and performance. We are very flexible when it comes to order size and meeting special customer requests for emergency delivery.

At present, we are equipped with:

•     Eight monolayer blown film lines from 3” to 360” (76-9144 mm)

•     One co-extruded three-layer blown film line

•     Two compounding lines

•     One pipe-strip processing line

•     One plastic recycling machine

We also have seven bag machines, including one top-seal (zipper closure) bag machine. Additionally, we have a two-color printing press.

How Does VCI Technology Work in Packaging Applications?

The success of our VpCI ® packaging lies in its Vapor phase Corrosion Inhibitor Technology, generically known as VCI. This technology creates a protective anti-corrosion environment inside each VpCI ® package. Application is easy, typically with little or no surface preparation needed. Special Vapor phase Corrosion Inhibitors embedded in VpCI ® packaging vaporize and travel through the air to form an invisible protective shield on all accessible metal surfaces inside the enclosed package. This VpCI ® shield does not alter metal properties. Instead, it blocks the ability of oxygen, moisture, and other corrosive elements to attack the metal surface and make it rust. After the metal part is taken out of the package, the VpCI ® molecules float away, and the metal components, machinery, or products are ready for immediate use, no cleaning or degreasing required.

Compounding Lines 

To produce a high technology VpCI ® film, we begin with a high quality concentrated masterbatch. Our modern, high-tech compounding lines are on the cutting edge of the latest technology. From precise feeding systems to custom screw designs, Cortec ® compounding lines are second to none for ensuring the highest film product quality to our customers. Our compounding lines will produce many different concentrated masterbatch products.* We are also able to integrate our VpCI ® Technology into biodegradable products. Cortec ® has been a pioneer in the formulation and compounding of biobased and/or biodegradable resins, with over fourteen years of experience in working with these materials. We offer a range of standard grades of our Eco Works ® compounded resins and will gladly make custom blends.

We take our high quality masterbatch and run it through one of our many blown film  extrusion  lines to transform resin into VpCI ® film. The film then goes through printing and is sent to the  converting  department to be made into a wide variety of different bag sizes and styles, including popular bag-on-roll and top-seal (zipper closure) formats. 

CAF Laboratory

We have a world-class laboratory that can perform testing compliant to Military Specifications (MIL-STD 3010) and ASTM standards (Section 8 Series D). The laboratory is located on-site at our blown film extrusion facility. All VpCI ® film batches are tested for Vapor phase Corrosion Inhibitor (VpCI ®) effectiveness. Moisture levels are tested by a Computrac Moisture Analyzer for any VpCI ® masterbatch production. Mechanical properties testing available include Tensile Strength, Puncture Resistance, Tear Strength, Dart Drop Impact, Coefficient of Friction, and Shrink. Static decay rates for Electrostatic Discharge (ESD) films are determined using desiccant chambers at 12.5% RH.

ESD films are manufactured as commercial equivalents to Military Specification MIL-PRF-81705 D. Each ESD order is tested on-site for static decay and surface resistivity. Static decay testing complies with Federal Standard 101 Method 4046. Surface Resistivity exceeds ESD S 11.11 specifications.

Custom VpCI ® films are developed and tested on site. Specific strengths, tear resistance, puncture resistance, tackiness, and slip qualities can be formulated according to the customer’s needs.
