1. Overview of Dental Floss
a. What is dental floss?
Dental floss is a tool used to clean teeth and maintain oral hygiene. It is used by inserting it between two teeth and pulling it through the gap to remove food particles and bacteria that a toothbrush cannot reach.
Dental floss is usually made from nylon or polytetrafluoroethylene (PTFE) fibers and comes in various types, including flavored versions to make the experience more enjoyable.
b. Types of machinery used in dental floss production
Machinery used in dental floss production includes:
- Nylon fiber production machines: These machines are used to produce nylon fibers of sufficient length and thickness for dental floss. The fibers are passed through a series of iron grids of different sizes to create different floss dimensions.
- Floss winding machines: These machines are used to package the floss after production. The floss is cut into small sections and wrapped in packaging of various sizes and shapes according to requirements.
- Printing machines: Used to print company names and logos on the packaging or directly on the floss to brand the product and enhance brand recognition.
- Quality inspection machines: These machines check the strength and flexibility of the dental floss, ensuring it does not break or snap during use.
- Packaging machines: Used to pack dental floss segments into standard packages, using various packaging technologies such as heat sealing, roll wrapping, and pneumatic sealing.

According to Clause 2, Article 24 of Decree 44/2016/ND-CP, there are two cases:
- If there is an employment contract between the employer and employee, the employer must sign and stamp the safety card for the Group 3 worker after completing training and passing the exam.
- If the worker is freelance or seasonal with no employment contract, the training unit must sign and stamp the safety card after the worker completes the training and passes the exam.
