The best material for custom stickers and labels depends on where and how they will be used. Industrial labels must be selected based on environment, surface type, durability requirements, and adhesive strength.

Common materials include:

• Polyester (PET): Best for durability, chemicals, and long-term use
• Vinyl (PVC): Flexible and ideal for outdoor or curved surfaces
• Polypropylene (BOPP): Moisture-resistant and cost-effective
• Paper: Best for short-term or indoor use

Choosing the right material ensures labels stay readable, attached, and effective over time. 

For labeling standards and system requirements, see our ANSI / ASME A13.1 overview.

What Are Custom Stickers & Labels?

Custom stickers and labels are used for identification, branding, safety, and operational purposes across a wide range of industries.

They are applied to:

• equipment and machinery
• tools and assets
• packaging and products
• safety signage and identification systems

Unlike standard labels, custom labels are designed to match specific environments, surfaces, and performance requirements. These labels are often used alongside pipe identification labels in industrial environments.

Why Material Selection Matters

The material is what determines whether a label lasts—or fails.

In real-world conditions, labels are exposed to:

• heat and cold
• moisture and chemicals
• abrasion and handling
• UV exposure

If the material isn’t matched to the environment, labels can:

• fade
• peel
• crack
• become unreadable

Durable materials are designed to maintain adhesion and readability even in harsh conditions. In systems like piping and equipment identification, choosing the right material directly impacts long-term performance.

Key Factors When Choosing Label Materials

Before choosing a material, consider these factors:

Environment

Indoor vs outdoor, exposure to moisture, UV, chemicals, or temperature extremes.

Surface Type

Smooth, rough, curved, textured, or metal surfaces all require different materials.

Durability Requirements

Short-term use vs long-term identification (months vs years).

Adhesive Type

Permanent, removable, or repositionable depending on application.

Application Type

Branding, safety, asset tracking, or compliance labeling.

Material selection should always be based on how the label will actually be used—not just appearance.

Common Label Materials Explained

Polyester (PET)

• Highly durable and long-lasting
• Resistant to chemicals, heat, and abrasion
• Ideal for industrial equipment and asset tags

Polyester is one of the most widely used materials for long-term identification because it maintains readability under harsh conditions

Vinyl (PVC)

• Flexible and weather-resistant
• Adheres well to curved or uneven surfaces
• Suitable for outdoor use and equipment labeling

Vinyl is commonly used when flexibility and outdoor durability are both required

Polypropylene (BOPP)

• Moisture and oil resistant
• Cost-effective for large-scale labeling
• Common in packaging and product labeling

Polypropylene balances durability and cost, making it a practical choice for many applications

Paper Labels

• Low-cost and easy to print
• Best for indoor or temporary use
• Not resistant to moisture or abrasion

Paper is useful for short-term labeling but not for industrial or outdoor environments

Specialty Materials for Harsh Environments

Some applications require materials designed for extreme conditions.

These include:

• Polyimide: High-temperature environments (electronics, aerospace)
• Polycarbonate: Impact-resistant and durable
• Anodized aluminum: Long-term outdoor and industrial use
• Chemical-resistant films: Designed for solvents, oils, and corrosive materials

These materials are used when standard label options are not sufficient for the environment

Adhesive Types: What Makes Labels Stick

Material is only part of the equation—the adhesive is just as important.

Permanent Adhesive

• Strong, long-lasting bond
• Ideal for safety, compliance, and outdoor use

Removable Adhesive

• Can be removed cleanly without residue
• Best for temporary or changing labels

Repositionable Adhesive

• Allows adjustment after application
• Useful for flexible labeling systems

Choosing the right adhesive depends on how long the label needs to stay in place and the surface it’s applied to. In many applications, these materials are used in pipe identification labels designed for long-term performance.

How to Choose the Right Label Material (Step-by-Step)

If you’re not sure which material to use, follow this process:

1. Define the environment
   Indoor, outdoor, chemical exposure, temperature range.
2. Evaluate the surface
   Smooth, curved, rough, or textured.
3. Determine lifespan
   Temporary (weeks/months) or long-term (years).
4. Choose material type
   Polyester for durability, vinyl for flexibility, polypropylene for cost balance.
5. Select the adhesive
   Permanent for long-term, removable for temporary use.
6. Test if needed
   Always test labels in real conditions before large-scale use.

This approach helps ensure the label performs as expected in real-world conditions.

Common Mistakes When Choosing Label Materials

These are the most common issues:

• Choosing based on cost instead of environment
• Using indoor materials outdoors
• Ignoring surface type (flat vs curved)
• Overlooking adhesive compatibility
• Not accounting for chemical or UV exposure

Most label failures come from mismatched materials—not poor printing.

Choosing the Right Material for Your Application

Here’s a simple way to think about it:

• Outdoor or harsh environments → Polyester or vinyl
• Curved or flexible surfaces → Vinyl
• Moisture or product labeling → Polypropylene
• Short-term or low-cost → Paper

The best material is the one that matches the real-world conditions your label will face. Material selection should always align with your overall labeling system, including color coding and identification standards. For color-based systems, see our pipe marker color code guide.

Choosing the right label material isn’t about picking the most durable option—it’s about choosing what actually fits your environment. When material, adhesive, and application are aligned, labels stay readable, secure, and effective over time.

A well-matched labeling system helps reduce replacement costs and keeps identification consistent across your operation.
