Heat-sealing strength, also known as heat-sealing strength or sealing strength, is an index for evaluating the sealing strength of heat-sealed parts of food packaging. If the heat-sealing effect is significantly stronger than the composite fastness, the heat-sealed parts are likely to be difficult to unpack. If the heat sealing strength is insufficient, the finished package will have problems such as openings, air leakage, and bag breakage.
Matching level of thermal shrinkability between composite layers of retort resistant composite packaging
In response to this problem, this article uses the LTS-05 tensile testing machine to test the tensile properties of the packaging materials before and after contact with the sauce.
It is of great significance to strengthen the monitoring of the composite fastness of composite membrane materials.
How to the adhesion fastness of printing ink on the surface of packaging bag？
For ketchup packed in flexible plastic packaging bags, if the tearing performance of the packaging bag is poor, the ketchup is not easy to take out. Generally, tearing performance is expressed by tearing load, tearing strength and other indicators.
The coefficient of friction is a physical quantity that characterizes the slipperiness of packaging materials. It is divided into two types: dynamic friction coefficient and static friction coefficient. It is an important testing index for packaging materials. The friction coefficient is directly related to the smooth progress of the packaging process.
Common pharmaceutical packaging quality problems monitoring solution
Monitoring proposal for rupture of non-PVC composite membrane infusion bag. The reason for the rupture of the PVC composite membrane infusion bag and its monitoring plan provide a reference for the pharmaceutical industry.
Testing method for peeling strength of aluminum-plated composite film for pharmaceutical packaging
If the carton for the transportation of pharmaceutical products has poor compression resistance, the carton will be easily deformed or even crushed due to external forces such as squeezing and stacking during the transportation process, resulting in the loss of the protective effect of the carton on the medical product. . Therefore, strengthening the monitoring of the compression resistance of cartons is an effective way to prevent the loss of medical products during transportation.
Under low temperature conditions, polymer flexible packaging materials have a tendency to increase brittleness, and brittleness is easy to occur.The flexibility and impact resistance of the material deteriorate at low temperatures, resulting in inability to withstand external impacts, causing damage such as bag breakage and air leakage.
