Various forms of tabbed sealing members are described along with the laminates from which the sealing members are formed. In some forms, the tabbed sealing members may be considered inverted tabbed sealing members for induction sealing as the induction heating layer is provided in the upper laminate instead of the lower laminate. In this regard, the induction heating layer is positioned further from the heat seal, contrary to conventional tabbed sealing members.

The invention relates to a sealant antifog composition for polyester films comprising anionic and non-ionic surfactants in a mixture of amorphous and (semi)crystalline polyesters. The invention also relates to a multi-layer film comprising a sealant layer having the above composition, to the use of said films in food packaging and to the packages obtained therefrom.

This invention relates a compostable lid for sealing a beverage capsule or a beverage pad wherein the lid comprises a natural-fiber based support obtainable by: (i) providing a first fibrous base sheet comprising natural fiber material sensitive to a gelatinizing agent; (ii) treating the first base sheet with a gelatinizing agent to give a treated first fibrous base sheet comprising gelatinized material; (iii) providing a second fibrous base sheet; (iv) contacting the treated first fibrous base sheet and the second base sheet with each other; (v) causing at least partial migration of the gelatinized material from the treated first fibrous base sheet into the second fibrous base sheet to give a multilayer product; and (vi) neutralizing and/or washing the product thus obtained and then drying it.
