Peelable seals including porous inserts

Abstract

Peelable seals including porous inserts are described. An example peelable seal includes a porous insert positioned between a first sheet and a second sheet. The porous insert includes a plurality of interwoven strands and a plurality of pores adjacent the interwoven strands through which a bond is formed between the first sheet and the second sheet when heat is applied to at least one of the first sheet, the second sheet or the porous insert.

1 . A peelable seal, comprising:
 a porous insert positioned between a first sheet and a second sheet, wherein the porous insert comprises:
 a plurality of interwoven strands; and 
 a plurality of pores adjacent the interwoven strands through which a bond is formed between the first sheet and the second sheet when heat is applied to at least one of the first sheet, the second sheet, or the porous insert. 
   
     
     
         2 . The peelable seal as defined in  claim 1 , wherein each of the plurality of pores is between about eleven micrometers and fifty micrometers. 
     
     
         3 . The peelable seal as defined in  claim 1 , wherein each of the plurality of pores is approximately 30 micrometers. 
     
     
         4 . The peelable seal as defined in  claim 1 , wherein the porous insert comprises a plastic material. 
     
     
         5 . The peelable seal as defined in  claim 1 , wherein the porous insert comprises a PET material. 
     
     
         6 . The peelable seal as defined in  claim 1 , wherein the first sheet and the second sheet each comprise at least one of a single layer plastic sheet or a multilayer plastic sheet. 
     
     
         7 . The peelable seal as defined in  claim 1 , wherein the first sheet and the second sheet each comprise a single layer PVC sheet. 
     
     
         8 . The peelable seal as defined in  claim 1 , further comprising a seal along corresponding edges of the first sheet and the second sheet to form a container. 
     
     
         9 . The peelable seal as defined in  claim 8 , wherein the container is separated into a first compartment and a second compartment by the peelable seal. 
     
     
         10 . A method of producing a container having a peelable seal, comprising:
 sealing a first set of corresponding edges of a first sheet and a second sheet;   positioning a mesh insert between the first sheet and the second sheet, wherein the mesh insert comprises:
 a plurality of interwoven strands; and 
 a plurality of pores adjacent the interwoven strands; 
   sealing a second set of corresponding edges of the first sheet and the second sheet to form the container; and   applying heat to a portion of the first sheet, the second sheet, and the mesh insert to form a peelable seal between the first sheet and the second sheet.   
     
     
         11 . The method as defined in  claim 10 , wherein forming the peelable seal between the first sheet and the second sheet comprises fusing the first sheet and the second sheet through at least some of the plurality of pores. 
     
     
         12 . The method as defined in  claim 10 , wherein applying heat to the portion of the first sheet, the second sheet, and the mesh insert comprises applying RF-energy to the portion of the first sheet, the second sheet, and the mesh insert. 
     
     
         13 . A container for use in the medical industry, comprising:
 a first sheet;   a second sheet;   a seal along corresponding edges of the first sheet and the second sheet to form the container;   a porous insert positioned between the first sheet and the second sheet, wherein the porous insert comprises:
 a plurality of interwoven strands; and 
 a plurality of pores adjacent the interwoven strands; and 
   a peelable seal between opposite edges of the first sheet and the second sheet and adjacent the porous insert, wherein the peelable seal is to form separate compartments in the container.   
     
     
         14 . The container as defined in  claim 13 , wherein a bond is formed between the first sheet and the second sheet through at least some of the plurality of pores. 
     
     
         15 . The container as defined in  claim 13 , wherein each of the plurality of pores is between about eleven micrometers and fifty micrometers. 
     
     
         16 . The container as defined in  claim 13 , wherein each of the plurality of pores is approximately 30 micrometers. 
     
     
         17 . The container as defined in  claim 13 , wherein the porous insert comprises a plastic material. 
     
     
         18 . The container as defined in  claim 13 , wherein the porous insert comprises a PET material. 
     
     
         19 . The container as defined in  claim 13 , wherein the first sheet and the second sheet each comprise at least one of a single layer plastic sheet or a multilayer plastic sheet. 
     
     
         20 . The container as defined in  claim 13 , wherein the first sheet and the second sheet each comprise a single layer PVC sheet.
