[Abstract] a production process of liquid pesticide soft packaging film, which is a four-layer film material of the packaging film, including modified polyester film (PET), aluminum foil (AL) Nylon film (NL) and modified polypropylene film (CPP) are processed by three dry composite processes. The technological process includes: printing patterns or words on one surface of modified polyester film (PET); The first compounding is to glue another non printing surface of modified polyester film (PET) with medium resistant adhesive, and laminated, rolled and cured with aluminum foil (AL); The second composite is to glue one surface of nylon film (NL) with medium resistant adhesive, and laminate, roll and cure with the other side of aluminum foil (AL); The third compounding is to glue one surface of modified polypropylene film (CPP) with medium resistant adhesive, and laminate, roll and cure the other side of nylon film (NL). The product produced by the invention has anti volatilization, anti-corrosion, anti deterioration, anti fading and strong mechanical properties, so that it can be widely used in the field of liquid pesticide soft packaging

[sovereignty] 1 A production process of liquid pesticide soft packaging film, which is characterized in that the packaging film referred to in the process is made of four film materials of modified polyester film (PET), aluminum foil (AL), nylon film (NL) and modified polypropylene film (CPP) through three composite processes. The process flow is: a packaging film printing, pattern or text printing on one surface of modified polyester film (PET); B for the first time, the other non printing surface of the modified polyester film (PET) is glued with a medium resistant adhesive, and laminated with aluminum foil (AL) without fatigue damage Winding and curing; C the second composite is to glue one surface of nylon film (NL) with medium resistant adhesive, and laminated, rolled and cured with the other side of aluminum foil (AL); D the third composite is to glue one surface of the modified polypropylene film (CPP) with a medium resistant adhesive, and laminated, rolled and cured with the other side of the nylon film (NL)
