For the latter, the shrinkage rate and contraction force of the cigarette film are required to be relatively large, so as to maintain the smooth, uniform and compact packaging effect of the cigarette for a long time. Therefore, strengthening the detection of the shrinkage performance of the cigarette film to ensure the suitability and uniformity of the shrinkage performance has far-reaching significance for improving the appearance and quality of cigarettes.
Proper shrinkage properties are important to the shrink packaging for bottled drinks and it is necessary for the manufacturers to test the shrinkage properties of the shrink films before use. This article provides a test method of the shrinkage properties of shrink film for your reference.
The screen protective film is usually pasted on the screens of electronic products such as mobile phones and computers. Its function is to protect the screen from water and dust, while preventing fingerprints from remaining on the screen. Its materials usually include PP, PVC, PET and AR. The test indicators for the adhesiveness of the screen protection film include primary adhesive strength, last adhesive strength, peel strength, etc. There are no relevant standards for the protection film in China. This article refers to GB/T 2792-2014 "Test Method for Peeling Strength of Adhesive Tapes". Adhesive testing of screen protectors.
Proposals to common quality problems of aluminum lamination packaging
Packaging sealing performance refers to the characteristics of the package to prevent other substances from entering or the contents from escaping. If the packaging is poorly sealed, it is easy to cause air leakage, liquid leakage, or damage to the packaging during long-term circulation and storage after leaving the factory.
The appearance reduces the grade of the product, and at the same time, it is easy to cause deterioration of the barrier properties, puncture resistance, impact resistance and other physical and mechanical properties of packaging materials, which in turn leads to a series of problems such as oxidation deterioration, deliquesce, and bag breakage. Therefore, it is particularly important to strengthen the detection of the influence of the ink on the composite fastness of the composite film.
The quality of aluminum medicinal ointment tubes is directly related to the quality of medicines. Therefore, it is very important to test the sealing performance of aluminum medicinal ointment tubes.
Summary of quality problems in milk powder and nutrient powder packaging
Before entering the production link formally, through the test of the film friction coefficient, the friction coefficient can be quantitatively evaluated, and the production risk can be minimized. So how to test the friction coefficient of the smoke film under high temperature production conditions?
How to solve the problems of easy opening and good sealing on the basis that the opening force required by the screw cap is within the acceptable range of the consumer for similar screw cap bottled cosmetics needs to be verified by effective monitoring methods.
