CleanMark Terms Glossary


Acrylic Adhesive - Pressure sensitive adhesive based on high strength, acrylic polymers; can be coated as a solvent or emulsion system.

Acrylic Emulsion - A water-based latex made with acrylic polymers, used in coatings and adhesives.

Adhesive -A substance used for sticking objects or materials together typically made from acrylic, rubber, UV solvent.

  • Permanent - Pressure sensitive adhesive; once this adhesive is in place it is permanent. Removing label from where it was would damage either the label or surface of which it was on.

  • Semi Permanent - Offer adhesion values between removable and permanent and are ideal for applications requiring more adhesive strength but also removability characteristics.

  • Removable - An adhesive characterized by relatively high cohesive strength and low ultimate adhesion; it can be removed easily form most surfaces; some adhesive transfer could take place depending on the affinity of the adhesive to the surface, will leave no residue behind.

  • Ultra Removable - A product with ultra removable adhesive would be that of a sticky note. The product will stick but can be removed without causing damage to where it was stuck and or the sticky note itself.


Back Lit Labels - Labels or overlays that are designed to be lit from behind and thus have more color depth.

Barcode Labels -Preprinted labels fitted with various types of bar codes and human readable text.

Blank and Pre-Printed Labels - Labels that can be used for a multitude of functions.


Caution and Warning Labels - Labels whose function is to illustrate potential dangerous activities to avoid, as well as potential consequences.

CleanMark Cleanroom -Completely sterile room that is also environmentally controlled.

Cleanroom Labels -Labels made from synthetic materials that will not particulate or outgas so they can be used in ISO certified cleanrooms. These labels maybe removable, replaceable, or permanent.

Cleanroom Tape -Tape made from synthetic materials that will not particulate or outgas so they can be used in ISO certified cleanrooms.

Control Panel - Also known as graphic overlays and are commonly used to identify switches, knobs, lights, and dials on equipment.

Cryogenics - Is the production and behavior of materials at a very low temperature.


Decals -In addition to increasing visual impact, the dome also serves to protect the image from damage.

Doming - Domed labels are printed pressure-sensitive labels that have a thick, dome-shaped clear polyurethane coating to create a 3D effect.

Die Cut -The process of cutting a desired shape into metal, paper, or other material in which sharpened thin steel blades are pressed into the chosen material which creates different shapes.


FIM IMD (Film Insert Moldingt & In Mold Decorating) -Processes for decorating injection molded parts during the molding cycle.


  • Glossy - Is shiny and reflects most light

  • Matte - Dull with no shine components

Flexography (Flexo) -A form of printing is essentially the modern version of letter press which can be used for printing on almost any substrate including plastic metallic films, cellophane, and paper.

Formed Components - Labels, overlays, functional materials that have been formed via a thermal or mechanical process to fit unique shaped parts.


Gaskets -A shaped piece or ring of rubber or other material sealing the junction between two surfaces.

Graphic Overlays, Labels, Badges -Graphic overlays are a critical printed interface layer component in electronic products providing both protection, and a surface for graphic printing to create a functional and user-friendly interface.


Indication (Gamma and Autoclave) - Labels fitted with indicating strips, dots, or inks that will change appearance according to different types of exposure.

Injection Molding -The shaping of rubber or plastic articles by injecting heated materials into a mold.

IPA (Isopropyl Alcohol Cleaning) - A highly effective, general use cleaning product used to clean a variety of substrates and remove a variety of soils. Used in CleanMark’s Cleanroom.


Laser Marking - A laser beam comes in contact with the surface causing the surface to melt or be cut at that point.


Membrane Switches -Printing method using metallic ink to create electrical panel controls.


Nameplate - Describes a label product generally manufactured of metal of other material that is designed to withstand exposure to adverse conditions. Usually contains information such as serial numbers of components, electrical requirements, and are generally affixed to products utilizing a permanent adhesive.


OEM Products -An original equipment manufacturer (OEM) traditionally is defined as a company whose goods are used as components in the products of another company, which then sells the finished item to users.

Optically Bonded Lenses -Refers to a protective glass that is glued in front of a display to enhance its readability. There are a wide variety of adhesives used for optical bonding processes.


Particulate - A very small particle, as of dust or soot. Are given off by the burning of oil, gasoline, and other fuels can remain suspended in the atmosphere for long periods.

Polypropylene - A material in which labels are made from. More durable than most label material and are tear-proof and waterproof. Can hold up in tough conditions and are resistant to fading and discoloration.

Powder Coat - Is applied like a paint, except this is a dry powder, after the curing process takes place then the coat will appear as paint. Powder coat does have a small amount of texture to it. A powder coat surface is tough to stick products to because of the texture.

Printed Electronics -The printing method used to create electronic devices by printing on a variety of substrates. Electrically functional electronic or optical inks are deposited on the substrate, creating active or passive devices.


Regulatory Labels - Labels that indicate certain practices and ingredients within a product as per a variety of governing agencies including but not limited to; ROHs, Reach, WEE, EPA, CSA, UL.

RFID - Labels that detect/identify radio frequencies and store information.

Ribbon (Clean and Standard) -Ribbons made from synthetic materials that will not particulate or outgas so they can be used in ISO certified cleanrooms.

RoHS (Restriction of Hazardous Substances) - Restricts the use of specific hazardous materials found in electrical and electronic products.


Semiconductor -Is a material that conducts current, but only partly.

Sterilized -Made free from bacteria or other living microorganisms.


Tamper Labels -Labels that indicate whether or not the packaging has been tampered with.

Thermal Transfer - Is a digital printing method in which material is applied to paper by melting a coating of ribbon so that it stays glued to the material on which the print is applied.


UV Resistant Labels - Labels that can withstand harsh temperatures, including UV rays.


Void Labels -Labels that when removed leave behind a “VOID” print to indicate that the associated product is no longer viable.
