【 Abstract 】 A liquid pesticide packaging film production process is the four-layer film material of the packaging film including modified polyester film (PET), aluminum foil (AL), nylon film (NL), modified polypropylene film (CPP) Three dry composite processes. The process flow includes pattern or text printing on one surface of a modified polyester film (PET); the first compounding is a media resistant adhesive on another non-printing surface of a modified polyester film (PET). Glue, laminate and laminate with aluminum foil (AL), winding, and curing; second compounding is the resistance to media-type adhesive on one surface of nylon film (NL) and the other with aluminum foil (AL). One-side lamination compounding, winding, and curing; the third compounding is the application of a medium-resistant adhesive on one surface of a modified polypropylene film (CPP) laminated on the other side of a nylon film (NL). Composite, winding, curing. The product produced by the invention has the advantages of anti-volatility, anti-corrosion, anti-deterioration, anti-fading and strong mechanical properties, and can be widely applied in the field of liquid pesticide soft body packaging.
【Sovereignty Items】 1. A process for the production of liquid pesticide packaging film, characterized in that the packaging film referred to in the process is modified polyester film (PET), aluminum foil (AL), nylon film (NL), modified The four-layer film material of polypropylene film (CPP) is processed by three times of composite processing. The process flow is: A. Packaging film printing A pattern or text printing on the surface of a modified polyester film (PET); B first composite The other non-printed surface of the modified polyester film (PET) is subjected to a medium-resistant adhesive sizing, laminated with an aluminum foil (AL), wound, and cured; C second composite to a nylon film (NL One surface of the surface is glue-resistant with a medium-type adhesive and laminated, wound, and cured with the other side of the aluminum foil (AL); D. The third compound is performed on one surface of the modified polypropylene film (CPP). Resistant to the medium type adhesive, laminated with the other side of the nylon film (NL), coiled and cured.
