plastic shopping bag manufacturers should strengthen the flexibility of plastic shopping bags, enhance their tensile strength, and extend the service life of plastic bags.
What properties should be paid attention to when bagged convenience bread comes into the factory? What is the reason for the increase in acid value (peroxide value) in instant noodle cakes? What are the reasons for the micro pinholes and air leakage on the surface of the instant noodle packaging bag?
The friction coefficient of the soft plastic packaging material is mainly affected by additives such as slip agent and anti-blocking agent added in the production process of the material, and it is also related to the stiffness and hardness of the material itself.
cigarette manufacturers should strictly control the barrier properties of BOPP film materials to water vapor.
How to solve the agglomeration of bottled powder health products? What should I do if bottled health drinks are prone to leakage at the mouth of the bottle? Why does the gas composition inside the nitrogen-filled packaging of health products change?
It is necessary to ensure that the product has a good sealing performance during the shelf life, so as to reduce the large risks and economic losses that the company will bear due to packaging and sealing problems.
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.
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.
