Properly dispose of unused flexible packaging polyurethane laminating adhesive.

Flexible packaging laminated Polyurethane Adhesive is a common auxiliary material in the compound production of food and daily chemical packaging, which has the characteristics of strong adhesion and wide adaptability. However, due to its special chemical properties, if the unused adhesive is stored and discarded at will, it will not only cause waste of raw materials, but also lead to curing failure, potential safety hazards and environmental pollution problems, so it must be standardized and properly handled.

 

The unused adhesive on duty should be sealed and preserved first. Polyurethane laminated adhesive is easy to react and solidify when it meets air and water vapor. The remaining adhesive should be put into a clean and sealed container in time, labeled with model and remaining date, and placed in a cool, dry, ventilated and light-proof special storage area, away from fire sources, heat sources, acid and alkali chemicals, to prevent high-temperature exposure and humid environment, and at the same time strictly abide by the shelf life requirements and give priority to recycling to avoid deterioration and scrapping of adhesive.

For the residual waste rubber that can't be used any more, it is strictly prohibited to dump it directly into sewers, the ground or mix it with ordinary domestic garbage. Waste adhesives are industrial wastes, which need to be collected separately and stored separately, and handed over to qualified professional institutions for unified recycling and disposal, so as to prevent soil and water pollution caused by random discharge.

 

In addition, the operator should standardize the operation, take protective measures, and clean the tools and site in time after handling the remaining glue. Standardizing the disposal of unused polyurethane laminating adhesive is not only the key to ensure stable production and control production cost, but also the basic requirement to implement safe production and protect the ecological environment.
