INFUSION BAG Abstract of the Disclosure An infusion bag for particulated food products such as tea, coffee and the like, constructed of a coextruded multilayer perforated thermoplastic film having a heat resistant outer layer of film forming resin and an outer layer of a somewhat less heat resistant film forming resin and having a multiplicity of minute uniform holes each of which is sufficiently small to prevent the migration of the particulated product therethrough and which are sufficiently large to permit adequate fluid flow therethrough. The heat resistant outer layer of the film forms the outside of the bag and the less heat resistant layer of the film forms the inside of the bag. The film is also substantially odorless and tasteless.
