In industries such as logistics, supermarkets, pharmaceuticals, and food, thermal paper self-adhesive labels (sticky labels) have become a mainstream label material due to their advantages, including no ribbon required, clear printing, and ease of use. However, adhesion, a core performance characteristic of labels, is directly related to reliable information identification during transportation and use. To ensure that labels maintain good adhesion in various application environments, establishing scientific adhesion testing standards is crucial. This article systematically introduces the adhesion testing standards and methods for thermal paper sticky labels to help users better select and use them.
If you need to purchase or wholesale high-quality thermal paper sticky labels, please contact Revolve CF, a thermal paper sticky label supplier, at HarveyXu@revolve-cf.com or https://www.revolve-cf.com.
Adhesion is one of the most critical properties of thermal paper self-adhesive labels, determining whether the label can adhere securely to various surfaces, such as cartons, plastic bags, metal surfaces, or glass containers. Insufficient adhesion can cause the label to peel or shift, leading to information recognition failures and even serious consequences such as product recalls.
Adhesive type: Mainly categorized as permanent and removable adhesives, each requiring different testing standards.
Substrate surface: Rough, wet, or low-energy surfaces can affect adhesion.
Application environment: Temperature, humidity, pressure, and time can all affect adhesion performance.
Storage and use conditions: Storage conditions (such as high temperature and humidity) can alter adhesive properties.
Choosing a reputable thermal paper sticky label supplier, such as Revolve CF, can effectively avoid adhesion issues caused by unstable raw materials.
Adhesion testing primarily adheres to international and industry standards, such as FINAT, ASTM, and GB/T. The following lists some of the most commonly used standards.
Purpose: Tests the initial adhesion strength of a label.
Common Methods:
Loop Tack (FINAT FTM 9): A strip of label material is formed into a loop, briefly contacted with the test surface, then pulled apart to measure the maximum pull force.
Incline Ball Rolling Method (GB/T 4852): The label is placed face-up at an angle, and the angle at which the steel ball stops rolling is determined. A smaller angle indicates stronger initial adhesion.
Application: Suitable for rapid labeling applications, such as assembly lines.
Purpose: Evaluates the ability of a label to maintain its adhesion under a vertical load after application. Common Standards:
GB/T 4851-2014: After applying a specific pressure to a sample, a weight is suspended and the time it takes for the sample to peel off is recorded;
PSTC 7 (Pressure Sensitive Tape Council): A widely used international standard method.
Significance: This test reflects the stability of a label under long-term use or high-temperature conditions and is an important reference indicator for selecting industrial-grade thermal labels.
Purpose: This test measures the force required to peel a label from its adhered surface, measured in N/25mm.
Main Standards:
FINAT FTM 1 / ASTM D3330: The force required to peel a label at a fixed speed at a 180° or 90° angle is measured;
GB/T 2792-2014: A Chinese national standard, performed using a standard testing machine.
Application: A high peel force indicates strong adhesion, making it suitable for applications requiring high adhesion, such as product transportation and cold chain logistics.
Label application environments are complex and varied, and a single test method often cannot fully reflect performance. The following are recommended test combinations based on different usage scenarios.
Recommended Test Items: Initial Tack + Low-Temperature Peel Strength + Maintained Tack
Note: Peel strength and lasting tack should be tested in a low-temperature environment (below -20°C) to simulate actual transportation conditions.
Supply Recommendation: Choose a thermal paper sticky label supplier with cold-resistant adhesive, such as Revolve CF.
Recommended Test Items: Maintained Tack + Peel Strength + High-Temperature Stability
Special Requirements: The adhesive must comply with environmental requirements such as ROHS and REACH.
Purchasing Recommendation: Prioritize labels certified for food contact use.
Recommended Test Items: Initial Tack + Quick Peel
Suitability Requirements: Easy to apply manually or by machine, achieving good adhesion in a short time.
Actual Application Case: Several major retailers have partnered with Revolve CF and widely use its barcode-printing thermal paper labels.
In addition to focusing on adhesion test standards, choosing the right label supplier and product requires comprehensive consideration of the following factors:
The facestock should have a good thermal coating to ensure clear printing.
The backing paper should have moderate release force to facilitate automated labeling.
Quality suppliers offer glues with varying tack levels and functionalities based on industry needs.
As a professional thermal paper sticky label supplier, Revolve CF offers a variety of customized glue solutions for industries such as cold chain, electronics, and logistics.
A reputable label supplier should be able to provide test reports from organizations such as SGS, CTI, and Intertek.
These reports guarantee product quality and environmental compliance.
