In the modern food packaging and food delivery industry, aluminum foil spout bags are widely used for large-capacity liquid packaging such as soup bases, soy milk, beverages, and condiments due to their advantages such as good sealing performance, portabi
The slitting process is the first step in the production of kraft paper bags, and its rationality directly affects the waste rate in subsequent processes.
In the production process of hand-held pure aluminum spout bags, ensuring that the pure aluminum layer is evenly covered and without defects is a key step in guaranteeing product quality and performance.
In the production of kraft paper bags, controlling the moisture content of the paper is a key step in avoiding deformation problems.
In recent years, sugar grain bags have undergone a series of technological innovations in sealing design. Through upgrades in three dimensions—material composites, structural optimization, and intelligent interaction—a comprehensive protective barrier has
The curing process promotes the post-crosslinking reaction of the adhesive by allowing it to stand at room temperature or with heat, which can significantly improve the interlayer bonding strength and environmental resistance.
