Even though we have been stopped from taking overseas trips for a long time, we remember the experience of going abroad. Before boarding a plane, we have to go through the most time-consuming process, the check-in procedure. Some airport may have self check-in kiosks in place to enable passengers to check in and print luggage tags quickly. RFID tags are what we are going to talk about today.


Adhesives for RFID tags
 

What are RFID tags?

RFID stands for Radio Frequency Identification, also known as electronic tags.
An RFID system consists of a tag, a reader and an integrated middleware system. Radio frequency identification is a contactless automated identification technology which can automatically identify target objects and obtain relevant data through radio-frequency signals in any severe conditions without human intervention.
The RFID technology is able to identify objects moving at high speed and multiple objects at the same time with rapid and convenient operation.
 

Applications of RFID tags

Medical treatment, personal applications, traffic, entertainment, logistics, manufacturing, security, environment/other applications.
 

Adhesives for bonding of RFID tags 

Hot-melt pressure sensitive adhesives are used during the process that RFID chips are manufactured into identification tags or fare cards. In the past, twin adhesive tapes were adopted and the cost was higher.
The hot-melt pressure sensitive adhesives are gradually replacing the tapes in current product lines since such adhesives have excellent adhesion and adequate heat resistance and are applicable for the bonding of RFID tags to common plastic materials.

7 features of hot-melt pressure sensitive adhesives for RFID tags

Feature	Description
High hardness	After being coating with the adhesives, plug-in or contact cards show higher levels of hardness.
Long-time use	Direct bonding after applying the adhesives without thermal activation during the manufacturing process.
Outstanding adhesion	Excellent adhesion to paper or PP materials.
Good heat resistance	Shear adhesion failure temperature (SAFT) is 76℃.
High temperature and humidity resistance	Our hot-melt adhesives can still firmly bond a paper card and a RFID chip together after being tested under a high temperature and humidity condition for three days.
Excellent water resistance	Without detachment after paper cards are soaked for a day.
Good low temperature resistance	Without detachment of bonded paper cards under -40℃.

Unique features of our hot-melt pressure sensitive adhesives for RFID tags

Feature	Description	Advantages
Well-oil-tight paper base materials	Paper base materials do not have oil leakage problems after being strictly tested at 60℃ for 7 days. This oil-tight feature enables tags to maintain their original appearance after long use.	Higher hardness of tickets Wider material application range High-speed automation Excellent resistance below -25℃ Long-time storage Transport and storage applicable under any conditions without tags being detached easily
Good adhesive strength	Our adhesives have excellent initial adhesion to steel, PET, and PP base materials and are applicable to most materials. The final peel strength can cause permanent damages to paper materials.
Great temperature resistance	The adhesives can be used in the conditions with normal temperature and also have great low temperature resistance to prevent detachment of tags from kraft paper when it is below -40℃.
