  Composite Machine is generally used for laminating tape casting film, air permeable film and non-woven fabric. It is suitable for baby diapers, medical protective clothing, food desiccant packaging bags and other industrial products; on the other hand, it is applied to non-woven fabrics and other materials for gluing (laminating) and cutting processing.

Composite Machine

  Pur hot melt adhesive is a kind of polyurethane (- nhcoo -) or isocyanate (- NCO -) with polar and chemical activity in molecular structure. It has excellent adhesion with materials containing active hydrogen, such as wood, leather, fabric, paper, ceramics and other porous materials, as well as plastics, metal, glass, rubber and other surface finish materials.

  Some Composite Machine substrate surface adhesion adhesive ability is poor, in order to improve this kind of substrate surface adhesion ability, ensure the coating quality, the substrate surface tension should reach 42-56mn / cm. Before coating, a set of corona processor can be added to carry out corona treatment on the surface of the substrate to make the surface hairy, so as to enhance the surface tension. In this way, the coating amount on the surface of the substrate can be increased to avoid bubbles.
