The heat-sealing effect of the heat-sealing of the packaging bag directly affects the overall sealability of the mask packaging, so improving the heat-sealing strength of the packaging is an important measure to keep the mask moist during storage and sales.
What are the packaging forms of plastic medical packaging? What should we do if the powder medicine packaged in the vial appears agglomerated? What are the key focus items of glass containers for pharmaceutical packaging?
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.
