Special heat glue for express packaging, highly adhesive and extremely strong, environmentally friendly and odorless. Good heat resistance, no glue separation during transportation, effectively preventing bag rupture, suitable for all types of express packaging materials.
1.Excellent wettability
Exhibits excellent wettability on the surface of PE/PP bags containing recycled materials
2.Good temperature resistance
no oil leakage in summer and no cracking in winter
3.Long-lasting bonding strength
The initial adhesion force and holding adhesion force are balanced, ensuring that the seal does not open during transportation.
4.High material compatibility
The bag body made of both new and old materials can achieve a firm bond.

1.Temperature Control
The recommended temperature for the glue cylinder is 160-170℃
The temperature of the hose and nozzle should be maintained at 165-175℃
A preheating period of more than 30 minutes is required for the first use
2. Equipment Maintenance
Clean the nozzles and filter screens thoroughly every week
Regularly check the working condition of the heating elements
3. Material Compatibility
Before use, test the surface tension of the substrate first.
It is recommended that when using the new batch of rubber compounds, a small-scale trial production should be conducted first to verify the effectiveness before commencing large-scale production.
1.Q: What should I do if the seal of the express bag seeps oil in summer?
A:This is due to insufficient heat resistance of the adhesive. It is recommended to use a high-temperature resistant formula.
2.Q: Why does the seal of the express bag easily crack in winter?
A:Low temperatures cause the adhesive to become brittle. It is necessary to switch to a low-temperature resistant formula and select an adhesive with a lower glass transition temperature.
3.Q: How to solve the poor adhesion of express bags containing recycled materials?
A:Recycled materials have low surface energy. It is advisable to use a specialized adhesive with high wettability and appropriately increase the application temperature to improve flowability.
