Plastic packaging film is an indispensable part of the modern packaging industry, it is widely used in food, medicine, cosmetics and other industries. For the production and users of plastic packaging film, it is very important to understand the size and thickness of the film.
1. common units of measurement
- Thickness: The thickness of plastic packaging film is one of the important indicators to measure its quality. In general, the thickness of the plastic packaging roll film is measured in micrometers (μm). For example, 15 μm, 20 μm, etc.
- Width: The width of the plastic packaging film is also one of its important parameters. In general, the width of the plastic packaging roll film is expressed in millimeters (mm). For example, 100mm, 200mm, etc.
- Length: The length of the plastic packaging roll film refers to the length of the whole roll film. In general, the length of the plastic packaging roll film is measured in meters (m). For example, 1000m, 2000m, etc.
- Weight: The weight of the plastic packaging roll film refers to the weight of the whole roll film. Typically, the weight of the plastic packaging roll film is in kilograms (kg). For example, 1kg, 5kg, etc.
2. measurement method
- Thickness measurement: The thickness measurement of plastic packaging roll film is generally carried out with a thickness gauge. Thickness gauge is a special instrument for measuring the thickness of the film, can be divided into mechanical and electronic two. When measuring, place the thickness gauge in the vertical direction of the roll film, press it gently, and read the displayed value.
- Width measurement: The width measurement of plastic packaging film is generally carried out with a ruler or tape measure. When measuring, place a ruler or tape measure flat on the width direction of the roll film, read the values of the edges on both sides of the roll film, and then calculate the average value.
- Length measurement: The length measurement of plastic packaging film is generally carried out with a tape measure. When measuring, fix the tape measure on one end of the roll film, then straighten it along the length direction of the roll film, and read the value on the tape measure.
- Weight measurement: The weight measurement of plastic packaging roll film is generally carried out by electronic scale. When measuring, place the whole roll of film on the electronic scale and read the displayed value.
All in all, understanding the common measurement units and measurement methods of plastic packaging film is of great significance for production and use. Producers need to strictly control the size and thickness of the roll film to ensure product quality; users need to understand the size and thickness of the roll film to ensure proper use.
