Abstract

The invention belongs to the field of packaging materials, and particularly relates to an emulsifiable concentrate pesticide packaging film which comprises a supporting layer, a first adhesive layer,an aluminum foil layer, a second adhesive layer and a heat sealing layer which are sequentially stacked, wherein the supporting layer adopts a bidirectional tensile polyester film or bidirectional tensile nylon film and is high in mechanical strength, the first adhesive layer is used for interlayer bonding, the aluminum foil layer is used as a barrier layer and a cold formed strength layer, and the second adhesive layer adopts maleic anhydride modified polyolefin resin and enhances cohesiveness of the aluminum foil layer and the heat sealing layer to solve the problem of swelling of an existing second adhesive layer due to pesticide organic solvent invasion. Besides, polyvinylpyrrolidone, alkyl glycoside, microcrystalline cellulose, nano-silica, nano-zirconium dioxide and coal ash, and deformation amplitude in heat sealing is decreased. Moreover, all components are directly applied to the aluminum foil layer and dried by a dry process to form the second adhesive layer, and a special hot-press forming device for processing is omitted.

Description

technical field [0001] The invention belongs to the field of packaging materials, and in particular relates to an emulsifiable cream pesticide packaging film. Background technique [0002] Pesticides are generally highly toxic and extremely harmful to the human body, so the packaging safety of pesticides is very important. Liquid pesticides are currently commonly used pesticide formulations. For a long time, liquid pesticides have been packaged in glass bottles. However, due to the disadvantages of high damage rate, poor sealing and inconvenient measurement of glass products, people have to seek other packaging methods. With the composite technology With continuous improvement and wide application of new materials, people have also begun to apply soft packaging technology to pesticide packaging, and "replacing glass with plastic" has become an irreversible development trend of pesticide packaging. [0003] At present, there are two commonly used structures for liquid pestic...
