Should the handwritten wristband be made of PVC or TVK?

Medical handwritten wristbands are identification wristbands that medical staff use a ballpoint pen or oil-based pen to manually write the patient’s name, gender, department, hospital number, diagnosis and other relevant information. It can be seen in many hospitals.

The handwriting wristband is mainly divided into two materials: PVC soft plastic film and DuPont paper. Therefore, there are generally two types of handwritten wristbands on the market: PVC handwritten wristbands and TVK (DuPont paper) handwritten wristbands. So what’s the difference between these two handwritten wristbands?
1. Different materials
The PVC handwriting wristband is made of environmentally friendly and non-toxic PVC soft plastic film. Different from the commonly known PVC, the raw material of PVC film is specially refined, so PVC is completely non-toxic and tasteless, and does not have any irritation to human skin or respiratory system. The TVK handwritten wristband is made of stretch-resistant DuPont TYVEK environmentally friendly synthetic paper, which is non-toxic, non-irritating and non-corrosive. Both materials meet the requirements of medical wristbands to ensure the safety of patients.
2. Different printing content
The PVC handwritten wristband only supports single-color or two-color printing patterns, and cannot print color patterns and barcodes. TVK handwritten wristbands can print both color patterns and barcodes.
3. Different ways of wearing
Ensuring the uniqueness of the identification object is one of the most important principles of medical identification wristbands, so both wristbands adopt a one-time anti-counterfeiting design. The PVC handwritten wristband is equipped with a one-time lock. When wearing, the PVC handwritten wristband with written information is wrapped around the patient’s wrist, and the tightness is adjusted. There is about two fingers of space, and the lock can be fastened.
The TVK handwritten wristband adopts a sticky design and uses anti-counterfeiting adhesive to ensure the uniqueness of the recognized object. After writing, wrap it around the wrist, adjust the tightness, peel off the release paper of the double-sided tape on the back of the anti-counterfeiting area (area engraved with the butterfly pattern) of the identification wristband, and align the double-sided tape on the adjustment area of ​​the identification wristband. superior. (Note: Because the wristband is for one-time use, it cannot be torn again after being attached, otherwise it cannot maintain its integrity)
4, the appearance size is different
If you compare the physical objects in your hand, you will find that the shape, length and width of the two wristbands are slightly different. The PVC handwritten wristband is narrow and long, while the TVK handwritten wristband is short and wide
