发明名称 Non-glossing thermoformed film
摘要 A process of calendering a sheet or a film having at least one textured surface entailing passing a web of polymeric resin through a nip between a rigid roll and a resilient roll is disclosed. The inventive process comprises slowing down the cooling rate of the web by rolling its textured surface about the resilient roll. The rate of cooling is in comparison to a corresponding process where the web is rolled about said rigid roll. Products thus produced are suitable for making thermoformed articles having low gloss.
