Common Label Materials for Automatic Labeling Machines: A Complete Guide

In modern packaging lines, automatic labeling machines play a crucial role in improving efficiency, consistency, and product appearance. However, choosing the right label material is just as important as selecting the right machine. In this guide, we will walk you through the most commonly used label materials for automatic labeling machines, their characteristics, and how to choose the best option for your products.

What Labels Are Used in Automatic Labeling Machines?

Most automatic labeling machines use pressure-sensitive labels (self-adhesive labels) in roll form.

These labels consist of three layers:

Face material (label surface)
Adhesive (glue layer)
Release liner (backing paper)

The machine peels the label from the liner and applies it directly onto the product surface, enabling high-speed and precise labeling.

Common Label Materials

To meet these demands, we engineered a dual labeling head non-stop round bottle labeling machine with the following key features:

Coated Paper Labels (Art Paper)

Coated paper labels are the most widely used option in the market.

Features:

Smooth surface with excellent print quality
Cost-effective
Suitable for general applications

Applications:

Food packaging
Cartons and boxes
Retail products

Limitations:

Not waterproof
Limited durability

Thermal Paper Labels

Thermal labels are widely used in logistics and warehousing.

Features:

No ink or ribbon required
Fast and convenient printing

Applications:

Shipping labels
Barcode labels
Warehouse management

Limitations:

Sensitive to heat and light
Text may fade over time

PET Labels (Polyester)

PET labels are a premium solution for demanding environments.

Features:

Waterproof and oil-resistant
Tear-resistant and highly durable
High-end appearance

Applications:

Cosmetics and personal care
Electronics
Outdoor and industrial products

BOPP Labels (Polypropylene)

BOPP is another popular film material, especially in high-volume industries.

Features:

Lightweight and flexible
Moisture-resistant
Available in transparent or white finishes

Applications:

Beverage bottles
Plastic containers
Food packaging

Laminated Paper (PP-based)

Synthetic (laminated) paper combines the advantages of paper and plastic.

Features:

Water-resistant
More affordable than PET
Good printability

Applications:

Food and daily chemical products

Types of Adhesives

Choosing the right adhesive is critical for label performance.

Permanent Adhesive

Strong bonding
Suitable for long-term labeling

Removable Adhesive

Easy to remove without residue
Ideal for retail and export packaging

Freezer Adhesive

Works in low-temperature environments

High-Tack Adhesive

Designed for rough or uneven surfaces

Why Roll Labels Are Essential

Automatic labeling machines require labels in roll form.

Roll labels allow:

Continuous operation
High-speed application
Accurate positioning

Without a release liner, the machine cannot peel and apply labels properly.

How to Choose the Right Label Material

When selecting labels for your automatic labeling machine, consider:

Product surface (flat, curved, rough)
Environment (moisture, temperature, friction)
Branding requirements (appearance, transparency)
Budget and production volume

Frequently Asked Questions (FAQs)

Q1: What types of labels are supported?

Our machine supports all standard self-adhesive labels in roll form, including paper labels, PET, BOPP, and other film materials.

Q2: Can it handle transparent labels?

Yes, the machine can handle transparent labels. We use a high-sensitivity label sensor specifically designed for transparent or clear labels to ensure accurate detection and positioning.

Q3: What is the max label roll size?

The standard configuration supports a maximum roll outer diameter of 280 mm, with a core diameter of 76 mm (3 inch).

Q4: Does it support different adhesives?

Yes, the machine is compatible with various adhesive types, including permanent, removable, and high-tack adhesives, as long as they are standard self-adhesive labels.
