There may be the following reasons for the bubble bag seal not breaking after sticking:
1. Improper selection of hot melt adhesive: hot melt adhesive that is not suitable for bubble bag material may be selected, resulting in insufficient viscosity. Solution: According to the material of the bubble bag, choose the appropriate bubble bag hot melt glue.
2. Insufficient heating temperature: too low temperature will affect the viscosity of hot melt adhesive. Solution: raise the heating temperature appropriately, but pay attention to avoid deformation of the material caused by overheating.
3. Insufficient amount of glue: insufficient amount of glue is not provided to ensure the bond strength. Solution: Increase the amount of glue to ensure that there is enough glue at the seal.
4. The surface of the bubble bag is not clean: oil and dust will reduce the bonding effect. Solution: Clean the surface of the bubble bag before bonding.
5. Unsuitable storage environment: high temperature, humidity and other environments may affect the viscosity. Solution: Make sure the bubble bag is stored in the right environment.
The above are some possible reasons and solutions for the failure of bubble bags. I hope it will be helpful to you.
