At the end of 2019, the sea packaging is preparing to add a number of production lines, after the resumption of work in 2020 has gradually started to put into use, including solvent-free composite machine. In the past, the dry compounding process used solvent-based adhesives. In the process of producing composite flexible packaging materials, the solvent in the adhesive needs to be dried before the iron box of the two substrates after gluing, while the solvent-free compounding process uses solvent-free adhesives. After gluing, the two substrates can be compounded without drying. The difference between the two different processes, it is clear that the solvent-free composite method has obvious advantages over the dry composite method. What are the advantages of solvent-free laminating machine with dry laminating machine? Many advantages of solvent-free laminating machine compared with dry laminating machine:
1. solvent-free compound to save resources
1. Not applicable to solvents;
2, there is no drying process, can save a lot of energy consumption;
3. The amount of glue is small, and the adhesive coating amount per unit area of the solvent-free laminating machine is about 2/5 of the adhesive coating amount per unit area of the dry composite;
Good 2. adaptability to environmental protection
The adhesive applicable to the solvent-free laminating machine is 100% glue and does not contain any solvent. Therefore, in the production process, except that a small amount of solvent needs to be used to clean the gluing part during shutdown, there is no solvent emission, no three wastes are produced in the production, and a large amount of volatile solvent will not affect the health of workers, nor will it pollute the surrounding environment, which is conducive to clean production.
3. contribute to the improvement of product quality
The composite film will not pollute the contents of the package due to residual solvents, and the product has good hygiene and reliability;
2. When compounding, the substrate will not deform the film due to the heating of the solvent and the drying channel, which is beneficial to ensure the certificate of the composite film.
