3. What are hang tag materials and their gsm?

Paper and paperboard are widely used for hang tag.
Standard gsm including: 300g, 350g, 400g, 600g and 700g
HUAYUAN adopts materials from UPM and Avery Dennison which guarantee quality, certifications, and the stability of adhesive performance.

4. What is highest and lowest storage temperature to RFID Tags? Any special request to the facestock and adhesive?

Flexible RFID Tag consisted of two parts: raw material and RFID inlay. It needs to be stored in 10°C - 30°C degree and RH20% - 60%. Do keep the package sealed before usage. RFID tags must be applied at room temperature, storing for at least 10 hours if the working environment is out of room temperature range.
Flexible RFID tags can be stored in temperature between -198°C to +150°C with special facestock and adhesive.
RFID tag working temperature is -20°C to +80°C, therefore, we can’t guarantee RFID tags’ performance when temperature out of this range. And standard RFID readers only work at room temperature as well.

5. How can flexible RFID tags be waterproof?

HUAYUAN has a variety of materials and glue solutions for waterproof, oil resistant, and chemicals resistant. Please tell us the object or material and the working environment to ensure that the label works properly in a specific environment.

6. What factors affect RFID frequency?

Only metal issue needs be considered for HF/NFC RFID Tag e-performance.
As UHF RFID is very sensitive to achieve the target performance, the dielectric constant of the working environment needs to be considered, like glass, marble, fabric etc. And water and metal affect frequency seriously.

7. How to increase UHF RFID Tag’s reading range?

* Optimize Antenna Design
* Antenna Size: Enlarge antenna dimension
* RFID Chip: Adopting a highly sensitive RFID chip, like UCODE 7/8, MONZA R6/R6-P
* RFID Reader: Select qualified reader
* RFID Reader Power
* Optimize cooperation of RFID tag antenna and reader antenna

8. Which RFID Tag with good omnidirectional performance?

Omnidirectional RFID Chip: IMPINJ MONZA 4QT
Antenna: Generally, antenna design in square or rectangle, such as 44x44mm, has good reading performance in multiple directions.
An omnidirectional antenna is composed of two sets of far-field antennas.

9. What issues affect RFID consistency? How to improve?

Since UHF RFID is very sensitive that all components and processes during production may affects its consistency. HUAYUAN has strict QC system by using Tagsurance online inspection equipment and Voyantic.
Please consultant detailed information with our sales and engineers.

10. What issues affects RFID tags’ performance?

In general, RFID tags’ performance including electrical performance, physical performance and reliability performance.
* E-Performance: Antenna materials, RFID tag converting process, as well as the object to be attached.
* Physical Performance: Distortions, bends, stretches, etc.
* Reliability Performance: Temperature, humidity, and other conditions, as well as the adhesion of adhesive layer.

11. Can Roll to Roll RFID Tags be CMYK Pre-printed?

Yes, full color can be CMYK pre-printed on paper or plastic face stock or liner.

12. Can different RFID chips share the same antenna design?

Definitely not. But the same serial of RFID chips could share the same antenna if their technical specifications are all the same, like IMPINJ MONZA R6 and R6-P, and NXP NTAG21X serial chips.

13. Can HUAYAUN design RFID antenna based on customers’ request?

Of course, please consult our sales and share all request of application and target performance. 

14. Can HUAYUAN do EPC encoding and QR printing? How to ensure the data accuracy?

Yes, we can do EPC encoding and QR/Barcode printing. And the OCR facilities, Tagsurance, for online verification system ensures data accuracy.

15. How to inspect Web RFID Tag?

By using Tagsurance online inspection equipment, and artificial visual inspection. The optical visual checking line will be used when quantity reaches 5m.

16. What are RFID Label packaging precautions?

RFID dry inlay requires 2 line paper tap protection on each side, packed with dry inlay, to protect RFID chip from crush damage.
RFID labels typically use a 3-inch roll core, and the OD is less than 210 mm.
Both packed by an anti-static bag with vacuum applied.
Please note, custom package can be offered.

17. What are RFID Label storage requirements?

RFID label needs to be stored at 10℃ ~ 30℃, and RH20-60% environment, with anti-static bag sealed. They can be stored for one year in such environment. 

18. What are RFID Apparel Tag standard format and their features?

Flexible RFID Tag, RFID Hang Tag, Fabric RFID Tag
* Flexible RFID Tag: Most cost-effective solution.
* RFID Hang Tag: Embedded RFID inlay into the hang tag, easy to use, and won’t affect the hang tag design.
* Fabric RFID Tag: 2-10 times washable. It solves the trouble that RFID tags or RFID hang tags are easily missing.

19. How to improve the softness of Fabric RFID Tag?

* Customized RFID inlay with thinner substrate and use softer fabric.
* Printing graphene or silver antenna on the fabric directly.

20. What are features to RFID Windshield Tags?

Flexible RFID Label and RFID Card are two standard formats as windshield tag. They are widely used for highway toll collection, parking lot access etc. Heat resistant, chemical resistant, anti-oil, anti UV and waterproof etc. are required due to the working environment. Furthermore, as some applications involve authentication, payment etc., special requirements for EPC memory and encryption levels are needed in such case.

21. Due to the complexity of the industrial environment applications, what factors need to be considered?

The factors need to consider as follows
Application environment, temperature, humidity, indoor or outdoor use, pressure, and anti-collision.
The material of the tracked object (such as metal, wood, plastic, carton, etc.), size, material, installation method, etc.
Electrical performance: reading and writing distance, direction, and group reading requirements.
Variable data, numbering, encoding, Logo printing, etc.

22. What product forms can be provided in waste management applications? What are the characteristics of these products and how to choose?

There are two product solutions for trash management, laminated PVC tags and RFID worm tags.
