Abstract

La présente invention aborde le problème de la fourniture d'un nouveau contenant approprié pour le transport et le stockage, ledit contenant supprimant de manière fiable une réduction sérieuse de l'aptitude à la commercialisation d'une récolte agricole ou horticole provoquée par des moisissures tout en empêchant la migration d'odeurs due à un composant actif antimicrobien, la coloration et la détérioration de la qualité, d'un nouvel emballage et d'un nouveau procédé de stockage. La solution selon l'invention porte sur un contenant pour le stockage à froid d'une récolte agricole ou horticole, ledit contenant étant pourvu d'un film antimicrobien à libération prolongée qui comprend une couche de film de substrat, une couche de composant actif antimicrobien volatil contenant un ou plusieurs composés choisis dans le groupe constitué de composés actifs antimicrobiens volatils ayant un point d'ébullition dans la plage allant de 100 à 240 °C, et une couche perméable aux composants actifs antimicrobiens volatils formée d'un film polymérisé par dépôt en phase vapeur, ces couches étant stratifiées dans cet ordre. Ce contenant satisfait aux exigences 1 à 3 ci-après. [Exigence 1] Le volume du contenant de stockage va de 25 cm3 à 250 000 cm3 inclus. [Exigence 2] La surface du film antimicrobien à libération prolongée va de 1 cm2 à 5 000 cm2 inclus. [Exigence 3] Le rapport de la surface (cm2) du film antimicrobien à libération prolongée au volume (cm3) du contenant de stockage est supérieur ou égal à 0,02.
