Pressure-Sensitive Labels

A pressure-sensitive sticker refers to a label, decal or adhesive tag that adheres to a surface when pressure is applied, eliminating the need for heat, water or solvents during the application process. These stickers feature a specialized adhesive that creates an immediate bond with surfaces such as glass, plastic, metal, cardboard and more, making them extremely versatile for various packaging and branding options. Pressure-sensitive stickers are widely used in industries where reliable adhesion and consistent product identification are required. These stickers can also be customized with different materials, coatings and finishes to match specific durability, aesthetic or regulatory needs.

Pressure-sensitive labels are self-adhesive labels that stick to a surface with a simple press, using an adhesive layer that doesn't require water, heat or solvent to activate. They consist of a face material, an adhesive and a release liner, and are commonly found on product like food and beverage containers, packaging, and medical supplies. Their popularity is due to their versatility, durability and ease of application, whether by machine or manually.

In the labeling industry, the terms "self-adhesive labels" and "pressure-sensitive labels" are often used interchangeably, but there is an important distinction worth noting.

Pressure-sensitive labels adhere to surfaces when pressure is applied; there is no need for heat, water or solvents to activate the adhesive during label application. Adhesion occurs simply by pressing the label onto a surface.

Self-adhesive labeling, on the other hand, is a broader term that refers to any label with a pre-applied adhesive. This includes pressure-sensitive labeling but also may refer to other adhesive types. For example, heat-activated labels have an adhesive that requires a heat source to bond to a surface. Likewise, moisture-activated labels (such as old-fashioned postage stamps) have an adhesive that activates with water.

So, while all pressure-sensitive labels are self-adhesive labels, not all self-adhesive labels are pressure-sensitive labels.

Pressure-sensitive labels are available in a wide variety of types to accommodate a diverse set of packaging and product identification needs across industries. Common types include prime labels, which are used as primary branding or product labels on retail goods, and secondary labels, such as barcodes or instructional stickers that supply additional information. Specialty options also exist, like tamper-evident labels for security, expanded content labels for regulatory or multilingual needs, and promotional labels that incorporate removable coupons or instant redeemable offers. Additionally, pressure-sensitive labels are used for food traceability, produce identification (PID) and price look-up (PLU) applications, each tailored for performance on specific surfaces or environmental conditions. Businesses can choose from an array of pressure-sensitive label types, each engineered to optimize durability, efficiency, compliance and shelf appeal based on their unique requirements.

Pressure-sensitive labels are constructed from a combination of carefully chosen materials, each selected to optimize the label’s performance and appearance for its intended application. The key components include the facestock, adhesive and liner.

• Facestocks can range from cost-effective papers, such as semi-gloss, matte, coated or uncoated sheets, to durable synthetic films like polypropylene (BOPP), polyester, vinyl and specialty materials designed for unique packaging or aesthetic needs.
• The adhesive layer, positioned beneath the facestock, may be permanent for long-term use, removable, repositionable, food-grade or engineered for challenging conditions like high-moisture or extreme temperatures, ensuring reliable bonding to surfaces such as glass, plastic, metal, cardboard or textured substrates.
• Liners serve as the backing that protects the adhesive until application and are available in a variety of materials, including super calendared kraft (SCK), glassine, clay-coated kraft (CCK) and plastic films like PET or polyethylene, providing stability during printing and dispensing. Enhancements such as specialty coatings, protective laminates, varnishes and unique finishes further contribute to the resilience, print quality and visual appeal of pressure-sensitive labels.

Selecting the right adhesive for different surfaces requires careful consideration of both the application environment and the material of the packaging or product. To ensure adhesion, businesses must evaluate factors such as surface energy, texture, cleanliness and the presence of coatings or contaminants.

• For example, high surface energy materials like glass and metal allow for strong bonding with standard permanent adhesives, while plastics or powder-coated substrates may require specially formulated adhesives with enhanced tack or chemical resistance.
• Temperature ranges during application and end use also play a critical role. Some adhesives are designed to remain effective in cold environments or withstand exposure to moisture, chemicals or UV light.
• It is also essential to determine whether the label needs to be removable, repositionable or tamper-evident, as each functionality demands a distinct adhesive chemistry and performance profile. Consulting with a label supplier and conducting thorough application testing are recommended, ensuring the final label maintains secure, long-lasting adhesion and supports both regulatory compliance and brand integrity across diverse packaging types.

Digital printing and flexographic printing offer distinct advantages depending on your label requirements, production volumes and desired customization. Selecting between digital and flexographic printing depends on factors such as run size, project complexity, the need for variable data and material preferences, ensuring that your pressure-sensitive labels achieve both optimal performance and brand impact.

• Digital printing excels in producing short to medium runs with minimal setup time, allowing for fast turnaround and the flexibility to incorporate variable data, such as unique barcodes, QR codes or sequential numbering directly onto each label. This process offers exceptional print quality, vivid colors, and easy customization, making it an ideal choice for brands that frequently update designs or require personalization for limited editions and market testing. Digital printing also eliminates the need for printing plates, which reduces setup costs, material usage and waste.
• Flexographic printing becomes highly cost-effective at scale, making it the preferred method for large-volume label runs where consistent image reproduction and high-speed output are essential. Flexography can accommodate a wide variety of substrates, including papers, films and specialty materials, while delivering durable, high-quality results and a versatile range of finishes and specialty inks.

Yes, sustainable options are increasingly available for pressure-sensitive labels, enabling businesses to align their packaging with modern environmental standards. Businesses can meet regulatory requirements and strengthen brand reputation by selecting pressure sensitive label solutions that support sustainability initiatives.

• Many manufacturers now offer label materials made from recycled content or sourced from responsibly managed forests, helping to reduce the reliance on virgin resources.
• Innovative advancements include biodegradable films, compostable face stocks and wash-off adhesives that facilitate the recycling of containers by allowing labels to be removed cleanly during industrial washing processes. In addition, thinner liners and efficient production methods contribute to waste reduction throughout the label’s lifecycle.
• With eco-friendly inks, such as water-based or low-VOC formulations, brands can further minimize their environmental impact without sacrificing print quality or durability.

Absolutely. Ensuring your pressure-sensitive labels comply with FDA and other industry-specific regulations is an essential part of the label development process. Regulatory requirements can vary significantly depending on the product type and sector, and be governed by distinct rules regarding content, materials, and labeling information.
