RFIDAK / Linen & uniform identification
Give each sheet, towel or uniform a UHF identity. Compare eight fabric tag models for sewing, pouch insertion or heat sealing, then match the selected construction to your laundry process and readers.
Start with the physical fit
Choose the available space and attachment first. Each model name opens its own datasheet, with no form required.

Match the exact code. LDT7010 and LDT301-7010S share a footprint but have different published frequency, temperature and installation specifications.
Pressure is model-specific. “Not specified” means the sheet does not provide a rating. Request supporting conditions if pressure extraction is part of your process.
Read temperature and time together
The eight model sheets each list the four exposures below. Use these as inputs to the sample plan for your actual laundry line.
| Process | Temperature | Duration | Listed cycles |
|---|---|---|---|
| Washing | 90°C | 15 minutes | 200 |
| Pre-drying | 180°C | 30 minutes | 200 |
| Ironing | 180°C | 10 seconds | 200 |
| Sterilization exposure | 135°C | 20 minutes | 200 |
These figures are not an independently verified result for 200 complete cycles through your combined process. Agree detergent and bleach concentration, mechanical load, attachment and read-performance criteria. A listed sterilization exposure does not establish sterilization efficacy.
The LDT301 sheets list storage at −40 to +120°C, with no separate operating-temperature range. LDT7010 lists operation at −25 to +110°C and storage at −40 to +110°C.
Include the temperature and duration of every step, chemicals and concentrations, extraction pressure, textile composition and any required test method. Agree the conditions before samples are approved.
Select the installation route
The installation has to hold through the same process as the tag. Approve placement, textile and attachment together.
Make the ID useful in your system
A single-tag read distance does not establish complete-cart performance. Validate the tag at the actual intake, sorting and dispatch read points.
Include your reader setup in the inquiry →Six LDT301 sheets list up to 7 m; LDT301-8030H lists up to 8 m, depending on the reader; LDT7010 lists about 6 m. The sheets do not identify power, antenna or textile test conditions. LDT301 models list 860–960 MHz; LDT7010 lists 865–940 MHz. Match the reader band and settings to the installation country.
Use representative wet and dry textiles, cart material, packing density, orientation and movement speed. Record missed tags and reads from neighboring loads within the allowed reading window, before and after the agreed processing.
The model sheets list UCODE 8 or UCODE 9. Confirm chip availability, memory, numbering and lock rules in the order. Keep the writable EPC, factory TID and printed number as separate fields; approve a read-back file and software import before batch encoding.
NXP UCODE 8 / 8m technical reference ↗Check the article behind the claim
OEKO-TEX STANDARD 100 concerns testing for harmful substances. It is separate from the wash-cycle and reader-performance checks above.
23.HCN.97349
Issued by Hohenstein for a UHF laundry tag using white polyester woven laminated fabric, conductive yarn and white polyester sewing thread. The published certificate shows an expiry date of 2027-02-28.
Match the ordered article to the certificate scope, including any backing, color or adhesive variation, and check current status. The LDT7010 sheet does not list this certification.
Quote & sample planning
Choose an application, attachment and model. On the next page, add process conditions, reader details, encoding, quantity and destination to an editable inquiry.
The standard MOQ baseline is 1,000 pieces; confirm your model and configuration in the quote. Agree sample costs, freight and the production schedule separately.

Model sheets reviewed September 9, 2026.
The eight linked model sheets list 200 cycles for each stated exposure: washing at 90°C for 15 minutes, pre-drying at 180°C for 30 minutes, ironing at 180°C for 10 seconds, and sterilization exposure at 135°C for 20 minutes. These are supplier datasheet statements. They do not establish the result of 200 complete cycles through your combined process. Agree chemistry, mechanical loads, attachment and reading acceptance criteria for a representative pilot.
The LDT301-5512S, LDT301-7015S and LDT7010 datasheets list 60 bar. The other five linked sheets do not state that pressure rating. Confirm how the tag will be loaded during extraction and request the applicable test conditions. The 0.6–0.8 MPa used in heat sealing is an installation setting and should not be treated as an extraction-pressure rating.
No. LDT301-7015H and LDT301-8030H specify heat sealing at approximately 210°C, 0.6–0.8 MPa and less than 18 seconds. LDT7010 gives a separate instruction: under 215°C, 18 seconds and 0.6–0.8 MPa. The other five sheets specify sewing, pouch or hem insertion. These press settings are attachment instructions; approve the tag, backing and textile together on the actual press.
A distance measured with one tag does not establish complete-cart read performance. Water, folded tags, metal carts, antenna layout, reader power, motion and the available read window can change the result. Test known item counts in representative wet and dry loads, record missed and unintended reads, and repeat after the agreed process exposure.
These are UHF EPC Gen2 tags. A phone’s built-in NFC reader works with supported 13.56 MHz NFC tags and does not read this UHF tag family. A mobile workflow needs an appropriate UHF accessory and compatible software, or a separately specified NFC product.
Certificate 23.HCN.97349 identifies a UHF laundry tag construction using white polyester woven laminated fabric, conductive yarn and white polyester sewing thread, under Product Class II. Match the ordered article to that scope and verify current status with the issuer. STANDARD 100 concerns harmful-substance testing; it does not establish wash-cycle life, sterilization efficacy or coverage of every model, color or adhesive variant.
Specify the exact chip, EPC length, numbering rules, lock requirements and output-file fields. Keep the factory TID separate from the writable EPC and any printed number. Read back the encoded samples and import the mapping into your software before batch approval. If a proposed substitute chip has different memory, approve the revised data format and RF performance first.
The standard tags-and-labels MOQ baseline is 1,000 pieces. Confirm the minimum for your selected model, chip, attachment and encoding in the quotation. Evaluation samples and pilot quantities are discussed separately under the sample policy. Ask for sample charges, freight, unit pricing, quote validity and the production schedule for the approved quantity; transit time is separate from production.
