Solvent-free grafting is the use of solvent-free adhesives for membrane grafting.
Grafting method: using a solvent-free glue containing the solid component of a machined urethane resin to lower the viscosity temperature and then it is applied to the substrate film and bonded to another film by a reinforced press roller
Combine multiple layers and complex structures
Production speed 250m/min
The glue used is a 1- or 2-component glue, a single-component glue used mainly for joining with paper materials
Advantage
Low production cost.
Reduced noise because there is no ductwork.
Do not pollute the environment.
High production speed, run in bulk.
There is no solvent left in the grafted film, so it is very suitable for food and pharmaceutical packaging.
