Method and apparatus for sealing materials without glue

A system, comprising:

• first and second material pieces, wherein the first material piece is paper material having a coating on at least a portion of a first side of the first material piece, wherein the coating includes at least one polymer having a softening point and capable of being heated to the softening point using radio frequency energy;
• a disc positionable between the first and second material pieces;
• and
• a die press including top and bottom press components operable to create a heat-seal between the first and second material pieces to fuse the first and second material pieces together around the disc, the disc being substantially surrounded by the heat-seal, wherein at least one of the die process components is operable to melt a portion of the coating of the first material piece to the second material piece using radio frequency energy to create the heat-seal.

A method, comprising:

• providing first and second material pieces to be heat sealed, wherein the first material piece is paper material having a coating on at least a portion of a first side of the first material piece, wherein the coating includes at least one polymer having a softening point and capable of being heated to the softening point using radio frequency energy;
• providing a disc and positioning the disc between the first and second pieces;
• and
• forming a first heat-seal with a die press fusing the first and second pieces together, thereby melting part of the coating of the first piece to the second piece and forming a space between the first and second pieces where the disc resides, the disc being substantially surrounded by the first heat-seal, wherein the die press includes top and bottom press components, wherein the forming includes causing the die press components to be pressed together and heating at least one of the die press components via radio frequency energy to create the first heat-seal, wherein at least one the first and second material pieces includes access means therein positioned over the space to access the disc.
