Clingz® Design Guides

ClingZ® Standard Design Guidelines
ClingZ , or static cling as it is often called, is a patented, electrically charged polypropylene film. The benefit of using ClingZ is its ability to cling to virtually any clean, dry surface without leaving a residue. This unique ability creates new and creative ways to provide graphic images for many different applications. These include POP advertising, retail promotions, pharmaceutical and educational signage and greeting cards. To maximize the ability to cling it is important to consider the following design recommendations.

ClingZ Certified Printers
Vinalith PlasPrint are a ClingZ certified printer with many years of experience with this substrate.

Minimum finished size should be at least 8 x 13cm

Design for as little ink usage as possible. Build PMS colours; process ink builds allow more charge to reach the surface than a solid PMS flood. 4-colour process is also less dense and adds less weight to the piece. The ClingZ film is highly reflective and does not require heavy ink coverage to achieve a quality image. Avoid designs that would leave heavy deposits of ink near the edge of the piece to prevent the film from curling. ClingZ, Inc. does not recommend the use of varnish or aqueous coating. They will reduce the charge, curl the film, and void all product warranties.

ClingZ is a polypropylene film tipped onto a 10pt. paper backer, and is offset printable.  The ClingZ material itself cannot be printed on both sides; however, the liner can be printed on the back side. Clear ClingZ can be printed reverse or right reading for window applications. To enhance the colour of an image on clear, an opaque white can be printed before a pass of 4 colour process, or add the white last if reverse printing.

ClingZ can be die-cut or kiss-cut to create unique images; avoid long thin pieces. ClingZ can also be perforated, scored and folded. Review any special finishing processes with your printer. These guidelines for designing on ClingZ are collected from users of ClingZ products and are intended to help designers maximize the creativity, performance and printability of the material.

ClingZ Standard.  Frequently Asked Questions

How long will ClingZ stay on a surface once it has been applied?
It depends on the texture of the surface, but an average time frame is up to 6 months. The smoother the surface the longer it will cling.

Is ClingZ repositionable? How often can it be moved?
Yes, ClingZ is repositionable. The fewer times it is moved the longer it stays on a surface.

What is the shelf life of printed ClingZ?
One year if it is wrapped and stored in a clean dry location.

What surfaces does ClingZ adhere to? Which are best?
will adhere to clean dry indoor surfaces (except cloth) on either the printed or unprinted side. Try it on glass, metal, wood, wallboard, brick, plastic, marble or stucco. The smoother the surface the longer it will cling.

Can ClingZ be inserted into envelopes, or tipped into magazines?

Does direct sunlight or humidity affect ClingZ?
Inform your printer of the location where ClingZ will be placed. If placed in direct sunlight the printer will recommend fade resistant inks. Normal indoor humidity has no effect on the film or liner.

What thickness and size is ClingZ available in?
is available in a variey of sizes. Please contact us for details.

Can you UV print or put a coating on ClingZ?
UV printing is fine if it is not subject to high heat exposure.  High heat will cause ClingZ to lose its electrical charge. Coatings are not recommended as they will reduce the charge and curl the film.

Are there imperfections in the film as a result of the charging process?
Yes. The appearance of lightning bolts is inherent in ClingZ as a result of the charging process, with an incidence of 3%-5% overall. Conventional inks will print over them.

Can ClingZ be kiss-cut or die-cut?
Yes. ClingZ can be perfed, die-cut, kiss cut, scored and folded.

Is ClingZ environmentally friendly?
Yes. The ClingZ film is a #5 recyclable polypropylene film and the 10pt paper backer can be recycled with any standard paper, it does not contain adhesives.

ClingZ Standard Offset Printing and Storage Guidelines

Storage Requirements
Store inside at room temperature, 65º to 80º F with relative humidity levels between 25% and 50%. Unwrap product once it has acclimated to press room temperature. Remove bands from skid 24 hours prior to running, leaving the ClingZ material in the original bag. Use the material within 4 hours of unwrapping and reseal any remaining unused material in the original bag. ClingZ is moisture sensitive and will wrinkle if improperly stored.

Ink Usage
Maximum ink density of 220% in the colour build with a line screen of 150-175 are recommended. Screen down inks and utilize under colour removal. Build PMS colours from process inks. Using PMS inks may cause the film to swell. Colour bars should be 1/2” from the lead edge of the sheet and 1” from the tail edge. Heavy deposits of ink near the edge of the image should be avoided to prevent film from curling. Minimize alcohol to 7-10% in fountain solution. Keep water levels low to eliminate ink emulsification and drying issues.

is a polypropylene film tipped onto a 10pt. paper backer. It is converted with a solid glue line on the gripper edge and a spotted glue line on the tail. Load the solid glue line to the gripper when feeding. Do not trim glue lines prior to printing. Run in short lifts of 200-250 sheets. Position feeder air blowers so the air separates sheets to minimize blocking; use additional side air blowers. Position side air toward the rear of the stack to blow and separate the first 5-10 sheets. Run at press speeds of 7000-7500 sheets per hour. The appearance of lightening bolts is inherent in ClingZ as a result of the charging process, with a 3-5% incidence overall. Conventional inks will print over them.

Static Eliminators
is an electrically-charged material. DO NOT USE STATIC ELIMINATORS. They will reduce the electrical charge within the material.

Varnish and aqueous coatings are not recommended on ClingZ. Coatings will dissipate the charge and curl the  material. ClingZ, Inc. will not accept claims, or warranty material if coated.

UV Printing/Screen Printing
UV and Screen printing are not recommended. Heat from UV lamps and the catalytic ink curing process reduce the electrical charge. Screen printing produces heavy ink coverage causing the film edges to curl. ClingZ, Inc. Willnot accept any claims, or warranty the material for UV or Screen printed sheets.

can be die-cut and kiss-cut, avoiding long thin pieces. Folding, scoring, and perfing can also be done.

Contact ClingZ, Inc. for Technical Assistance. Polybagging is a preferred method for packaging ClingZ. Do not shrink wrap as heat used in the process will reduce the electrical charge.

VOC’s (Volatile Organic Compounds/Solvents)
Exposing ClingZ to VOC’s will cause wrinkling and charge loss in the material. VOC’s may be present in fresh corrugated packaging and printed materials, so use care when packaging ClingZ with other materials.
