Plastic bags thickness range and measuring method

The thickness of the plastic bags range and measuring method 1. What is the thickness of the plastic packaging unit? The thickness of the plastic packaging unit for general use & other Silk & throughout; As a unit, a wire is 0. 01 mm, of course, some places also use micron as a unit, 1 um ( Micron) = 0. 001mm（ Mm) 。 2. Well, what's the thickness of the plastic bags in general? Our daily use plastic bags according to the design and use of the functions of different thickness are not identical, but the basic are 0. 025mm- 0. Between 15 mm, 2. 5 wire to 15 wire. Because in 2008 countries issued plastic limit, the thickness of the plastic bags must be reached 0. Above 025 mm, the thickness of above is called green shopping bag, below the thickness is called & other; Thin bags & throughout; Or & other Ultra-thin bags & throughout; 。 In fact, the thickness of the plastic bag can be custom-made, from 0. 0075 mm to zero. 15 mm can be produced. Plastic bag size can be customized, customized according to user demand, there is no fixed size. But less than 0. 025 mm bag is special function or is commonly use very large such as garbage bags and bags of thickness are basically in 0. 01 mm to 0. 02 mm between. 3. The thickness of the plastic bag how to measure it? Tend to use thin film thickness gauge measurement, measurement is usually the thickness of single layer plastic bags. The correct measurement method is to measure the thickness of a few different positions and then averaged, because generally plastic bags if there is no special purpose, thickness will not very accurate control, often have thickness error of about 5%. A 10 silk plastic bag thickness measured is 9. Wire 5 or 10. Five SiDou belongs to the normal range of error. Bags thickness measurement methods and tools 1 bag thickness measurement tools are used for measuring the thickness of the bags according to the accuracy requirement, there are two kinds of different film thickness gauge and high accuracy of film thickness gauge. If it is industrial packaging bags or shopping bags, the accuracy is not high you can only use ordinary film thickness gauge measurement, the precision of this kind of thickness gauge is generally 0. 001mm。 If it is food sack or pharmaceutical packaging these packaging requirements higher then use high precision measuring film thickness gauge, this kind of the precision of the thickness gauge is 0. 1 um, namely zero. 0001mm。 Film thickness gauge: high precision thin film thickness gauge: 2 bags thickness measurement method of simple measuring method is the plastic bags of monolayer is measured directly using the instrument, measuring several times after the average. Thickness in the lab for quality test is more complex, the method is as follows: longitudinal ends from the sample about 1 m, take the sample, the entire width along the horizontal specimen width of 100 mm. The surface of the sample should be no fold, no pollution, no dust pollution, etc. According to the uniform sample length method to locate the thickness measuring points, as follows. 一个。 Sample length & le; 300 mm, at 10 o 'clock. b。 Sample length - in 300 Between 1500 mm and 20 points. c。 Sample length & ge; 1500 mm, 50 mm should be from the start. After the measurement to the formula to calculate the results. Measure thickness of plastic packaging bags: ENDPE/PO/PP/PVC/CPE/PPE/OPP/EVA
