Film heat shrink tester; Feature Interpretation; Laboratory conditions
Therefore, manufacturers should strengthen the detection of the water vapor transmission rate of foam glass to verify the barrier performance of foam glass to external moisture.
Therefore, the abrasion resistance of the ink layer of paper prints cannot be ignored.
Permeation R and permeability coefficient P are not to change with the variation of pressure difference.
Three test chambers are tightly designed together, which facilitates temperature and humidity control. The comparison of test results of the three test chambers will be more rational and precise as the humidity and the temperature are evenly distributed due to the patented technique, especially when the test materials are temperature and humidity sensitive. External humidity generator is optional for humidity controlling.
How to Select Gas Permeability Tester? Pressure differential method Applications and Significance
This article describes the importance of moisture permeability to diapers by introducing the moisture permeability test of diapers. Therefore, diaper manufacturers should strengthen regular monitoring of the moisture permeability of the outer PE film of diapers.
tobacco manufacturers should strictly control the barrier properties of aluminized paper for cigarette packs against water vapor.
The abrasion resistance of the ink layer of the carton sample tested in this test is 96%, which is good in abrasion resistance.
How to choose the coefficient of friction （COF）tester correctly? Coefficient of friction (COF) is an important physical index of the film for packaging.
Medical dressing-related manufacturers should strengthen the monitoring of water vapor permeability of products to prevent the water vapor permeability of products from being too low, resulting in difficult wound healing.
If the tensile strength of the plastic woven bag body is low, that is, the flexibility of the bag body is poor, and the bag body is prone to damage and leakage in the process of storage and circulation, which not only causes the leakage of the package contents, but also reduces the The life of plastic woven bags.
