▎ 摘　　要

NOVELTY - Aging-resistant packaging bag comprises a poly(ethyl benzene-1,4-dicarboxylate) alumina layer, a first adhesive layer, nylon film layer, second adhesive layer and polyethylene layer. The first adhesive layer is a special adhesive for aluminized film. The second adhesive layer is formed by curing a second adhesive. The second adhesive comprises 5.6-12 pts. wt. dimer acid, 0.6-1.2 pts. wt. ethylenediamine, 0.1-0.3 pts. wt. xylene, 2-3 pts. wt. epoxy resin, 20-30 pts. wt. poly(ethyl benzene-1,4-dicarboxylate), 3-5 pts. wt. glass fiber, 0.5-1.5 pts. wt. nano silica, and 1-3 pts. wt. maleic anhydride grafted polyethylene glycol. USE - Used as aging-resistant packaging bag. ADVANTAGE - The packaging bag has the advantages of good thermal aging resistance and ultraviolet aging resistance, strong barrier property, prolongs the storage time of the internal storage material, and having the effect of repelling insects.
