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.
Analysis and Solution of Common Quality Issues in Health Products Packaging
What is vacuum packaging? Why use vacuum packaging? How to ensure the sealing performance of vacuum packaging? How to check the quality of the leakage performance?
The mouth of the jam bottle is mostly packed with screw cap, that is, it needs to be manually twisted to open the cap before eating. If the cap is sealed too tightly, it is not convenient for the eater to open. If the cap is not tightly sealed, the bottle will leak Causes jams to deteriorate during the shelf life. How to solve the problem that the screw cap bottled jam has proper cap sealing and good cap opening force requires effective detection methods to verify. In this paper, the Link Testing Lttt-20 torque meter is used to test the torque value of the sample.
The pendulum impact energy of the film is a physical quantity that measures its impact resistance. Generally speaking, the higher the pendulum impact energy, the better the impact resistance and flexibility of the film. After the film is used for packaging products, it will inevitably be impacted by external forces during the later transportation and storage. If the impact resistance of the film is poor, it is easy to break the bag under such impact or impact, so it has good resistance. Impact performance is one of the necessary properties of film materials.
Packaging sealing performance refers to the characteristics of the packaging bag to prevent other substances from entering or content overflowing. If the packaging is poorly sealed, the packaging leaks or breaks during long-term circulation and storage after leaving the factory, causing the content to occur Quality problems such as mildew, agglomeration, and swelling of bags occur, and enterprises suffer greater risks and economic losses as a result.
