Web materials for use in forming reclosable packages generally include a first material layer made of a barrier material, and an active agent carried by the first material layer. When embodied as a bag, the web is used to form at least one of the body panels of the bag, with a pair of opposing body panels joined together along a pair of opposing sides, with a bottom bridging the sides in order to define a compartment between the opposing body panels. The active agent is disposed on the first material layer so as to be in communication with the compartment.
L'invention concerne des matériaux en bande servant à former des emballages refermables, lesquels matériaux comportent de manière générale un première couche de matériau constituée d'un matériau barrière et un agent actif appliqué sur cette première couche de matériau. Afin de réaliser un sac, la bande est utilisée pour former au moins une des parois du sac, une paire de parois opposées étant assemblées le long d'une paire de côtés opposés et un fond s'étendant entre les côtés pour définir un compartiment entre les parois opposées. L'agent actif est appliqué sur la première couche de matériau de manière à communiquer avec le compartiment.
