Choosing the right label specification involves more than selecting a material or finish. The facestock, adhesive, release liner, printing method, and surface treatment must work together to meet the requirements of the packaging, application environment, and finished appearance.

 

We help customers evaluate these factors when developing custom product labels, packaging labels, and specialty stickers. Material and finishing options are selected according to the intended application, artwork, order specifications, and confirmed production capabilities.

 

Label Materials
 

The facestock determines the label's appearance, print surface, flexibility, and resistance to environmental conditions. The appropriate choice depends on the packaging substrate, application method, and conditions the label will encounter during use.

Paper Label Materials

Paper labels are commonly used for product identification, retail packaging, and applications where a printable surface and a paper-based appearance are preferred.

Coated Paper
Coated paper provides a smoother printing surface than many uncoated papers. It is suitable for product labels requiring clear text, detailed graphics, and well-defined brand colors.

  • Typical applications: Consumer product packaging, retail products, and general-purpose product labels.
  • Key considerations: Surface finish, ink compatibility, moisture exposure, and the need for additional surface protection.
  • Finishing compatibility: Lamination and foil stamping may be considered when supported by the selected paper and production process.

Uncoated Paper
Uncoated paper has a more natural, less glossy surface and can be suitable for designs that emphasize a simple or understated appearance.

  • Typical applications: Selected product labels, paper-style packaging labels, and designs requiring a natural visual texture.
  • Key considerations: Paper absorbency, ink behavior, surface texture, and the clarity of fine details.
  • Finishing compatibility: The suitability of foil stamping, embossing, or other decorative treatments should be checked against the specific paper grade.

Thermal Label Paper

Thermal paper is designed for image formation through heat-sensitive technology rather than conventional ink-based printing.

Typical applications: Product identification, logistics, inventory, and selected retail labeling applications.

Key considerations: Direct thermal and thermal transfer are different printing methods. The material must match the intended printer, ribbon requirements where applicable, and expected label life.

Important note: Thermal paper should not be selected solely on price. Exposure to heat, sunlight, friction, and certain chemicals may affect image legibility, depending on the material grade.

Film Label Materials

Film labels are often considered when paper may not provide the required flexibility, moisture resistance, or surface durability. Performance depends on the specific film grade, adhesive, printing system, and finishing construction.

BOPP / PP Film
Polypropylene film is commonly used for product labels where a smooth surface, clean appearance, and resistance to moisture are important.

  • Typical applications: Selected food and beverage packaging, personal care products, household products, and other consumer packaging.
  • Appearance options: Depending on the available stock, options may include white, clear, or other specified film constructions.
  • Key considerations: Packaging surface energy, container curvature, application temperature, and the required resistance to moisture or handling.
  • Important note: PP film is not automatically suitable for every plastic container. Adhesive compatibility and application testing may be necessary.

PET Film
Polyester film is considered for applications requiring dimensional stability and particular levels of surface or environmental resistance.

  • Typical applications: Selected durable product labels, technical identification labels, and applications where the properties of the specific PET construction are appropriate.
  • Key considerations: Required thickness, transparency or opacity, printing compatibility, adhesive selection, and exposure conditions.
  • Important note: Chemical resistance, temperature performance, and outdoor durability must be verified against the exact material construction rather than assumed from the PET designation alone.

PE Film
Polyethylene film is flexible and may be suitable for packaging with curved, squeezable, or deformable surfaces.

  • Typical applications: Selected flexible bottles, tubes, and containers where label flexibility is important.
  • Key considerations: Container deformation, film flexibility, adhesive performance, and the risk of lifting or wrinkling during application and use.
  • Important note: PE film may require a carefully matched adhesive and application process, particularly on low-surface-energy plastic packaging.

Transparent and Specialty Label Materials

Transparent labels can help create a "no-label" appearance on suitable clear packaging, while specialty materials can support specific visual or functional requirements.

Before selecting a transparent or specialty construction, confirm:

  • Whether the packaging surface is clear, colored, curved, or textured.
  • Whether the label needs a transparent, white, metallic, or opaque background.
  • Whether white ink or other special printing requirements are necessary for the intended artwork.
  • Whether bubbles, visible adhesive, or background interference could affect the final appearance.
  • Whether the required material and printing process are available for the order.

 

Adhesive Selection

Adhesive selection is as important as facestock selection. A label that prints well may still fail if the adhesive does not match the packaging surface, application conditions, or service environment.

Permanent Adhesive

Permanent adhesives are designed to provide lasting attachment under their specified conditions of use.

Suitable applications may include: General product labels, retail packaging, and product identification labels where routine removal is not required.

Selection should consider the surface material, surface energy, cleanliness, application temperature, and the time allowed for the adhesive to build its bond.

 

Removable Adhesive

Removable adhesives are designed for applications where label removal is required within specified conditions.

Suitable applications may include: Selected temporary labels, promotional labeling, and products requiring removable identification.

Removability depends on the adhesive formulation, surface, dwell time, environmental conditions, and removal method. A removable adhesive does not guarantee residue-free removal from every surface.

 
Release Liner and Label Construction

 

A self-adhesive label typically consists of three main components:

Facestock: The printable or decorative surface material.

Pressure-sensitive adhesive: The layer that bonds the label to the target surface.

Release liner: The backing that protects the adhesive before application and supports handling and dispensing.

The release liner is not merely packaging waste; its properties can affect label conversion, dispensing, and application performance.

 

When specifying a label, consider:

Liner type and thickness: The liner must be compatible with the intended die-cutting, dispensing, and application process.

Roll or sheet format: The final format should match the customer's storage, handling, and labeling equipment.

Dispensing requirements: For machine-applied labels, liner release, label spacing, roll direction, and winding configuration may need to be specified.

Die-cutting and stripping: The liner and facestock construction should be suitable for the required label shape and converting process.

The appropriate liner and delivery format should be confirmed together with the label dimensions and application method.

 
Printing Options
 

The printing method should be selected according to artwork complexity, color requirements, order quantity, material compatibility, and finishing requirements.

Four-Color Printing

Four-color process printing generally uses cyan, magenta, yellow, and black (CMYK) to reproduce a broad range of colors and images.

It can be suitable for labels containing product photography, gradients, and multi-color graphics.

Important considerations include:

  • Artwork resolution and file preparation.
  • Bleed, trim dimensions, and safe areas.
  • Color references and approved artwork.
  • Substrate color and surface characteristics.
  • Registration requirements and the compatibility of subsequent finishing processes.

Brand-critical colors may require specific color references or an agreed proofing procedure. The final result can vary with the substrate, ink system, and production conditions.

Digital Printing

Digital printing transfers artwork directly from a digital file without conventional printing plates. Depending on the equipment and material, it may be appropriate for short runs, variable artwork, or jobs requiring changes between versions.

Before choosing digital printing, confirm the available print technology, compatible materials, color requirements, finishing compatibility, and production quantity.

Digital printing and digital inspection are separate functions. If digital equipment is used for proofing or quality checks, the exact workflow should be confirmed before it is described as a quality-control capability.

 

Surface Finishes and Decorative Effects

 

Surface finishing can change the appearance, texture, and protection of a label. The appropriate finish depends on the substrate, artwork, intended use, and compatibility with subsequent production processes.

Gloss Lamination
Gloss lamination adds a glossy surface layer and can increase visual contrast and color vibrancy.

  • Consider it when: A shiny appearance is desired or the label requires an additional protective surface layer.
  • Check before production: Film compatibility, adhesion between layers, flexibility, and whether the finish affects barcode readability or other functional requirements.

 

Matte Lamination
Matte lamination creates a lower-gloss surface that can support a more restrained appearance.

  • Consider it when: The design calls for a soft, understated finish or reduced surface glare.
  • Check before production: The effect on color appearance, fine details, surface marking, and any required writing or scanning functionality.
  • Lamination can provide additional surface protection, but it does not automatically make a label waterproof, chemical-resistant, or suitable for outdoor exposure. Those properties depend on the complete label construction.

 

Foil Stamping
Foil stamping transfers a decorative foil onto selected areas of a label to create metallic or other specialty effects, depending on the foil used.

  • Typical design applications: Logos, product names, borders, and selected decorative details.
  • Artwork considerations: Foil areas should be clearly identified in the artwork or production file. Very fine lines, small text, and intricate details require review for production suitability.
  • Material considerations: The paper or film surface, foil type, and process conditions must be compatible. The effect should be confirmed on the intended material where appearance is critical.

 

Embossing and Debossing
Embossing creates raised details, while debossing creates recessed details in the label surface.

These processes can add tactile depth to logos, lettering, or selected design elements.

Before production, confirm the location and size of the effect, the substrate's suitability, and the relationship between the textured area and printed artwork. Fine details and heavily textured designs may require adjustments to maintain clarity.

 

Die-Cutting
Die-cutting determines the final label outline and separates the label shape from surrounding material.

Labels may be produced in standard geometric shapes or custom outlines, subject to tooling and production requirements.

Key specifications include:

  • Finished label width and height.
  • Corner radius and shape complexity.
  • Bleed and safe-area requirements.
  • Spacing between labels.
  • Roll or sheet layout.
  • Compatibility with the intended dispensing or application method.

For irregular shapes or labels intended for automated application, the cutting layout and finished format should be confirmed before production.
