Hot melt adhesive particles for high-speed sealing of cardboard boxes are not necessarily better with higher tensile strength. The sealing fastness also depends on the wetting of the corrugated paper by the adhesive particles, the cooling speed of the adhesive dots, the spraying rhythm, and the pulling direction during transportation. Sunlife hot melt adhesive recommends determining the carton material, sealing size, line speed, and transportation environment before selecting and verifying.
The tensile strength on the test report can only be used as a screening indicator and cannot directly represent the sealing effect on site. High weight cardboard requires more stable adhesive point support, and low-temperature transportation will increase the risk of adhesive layer cracking; Excessive glue points can also increase glue consumption, extrusion, and equipment pollution.
Only by providing cardboard box samples, sealing machine models, speeds, and transportation environments can Guangzhou Sunlife Trading arrange targeted samples and acceptance conditions. Suppliers and customers jointly confirm standards, which is usually more reliable than comparing individual material data.
Q: Can the tensile strength report represent the sealing effect?Answer: It cannot fully represent the situation, as the site is also affected by paper materials, glue points, equipment, and rhythm.
Question: Is the more adhesive points, the stronger it is?Answer: Not necessarily. We should pursue a uniform and effective amount of glue to avoid overflow and equipment contamination.
Q: How to apply for a sample?Answer: Provide cardboard box samples, equipment models, speeds, and transportation environments to facilitate matching and verification plans.
