PERIMETER SEAL FOR MULTILAYERED MATERIAL AND ENCAPSULATION SEAM

摘要

PROBLEM TO BE SOLVED: To provide a container which can form a strong peripheral seam suitable for medical uses.

SOLUTION: The container comprises a first planar member 218, a second planar member 222, a first seam 224 and a second seam 226. The first planar member 218 is made of a multilayered polymeric material and further comprises a first substrate 238 and a first layer 246. The first layer 246 is disposed on a portion of the first substrate 238 to separately define a first overlap area 258 and an adjacent first peripheral flange 262. The second planar member 222 is made of a multilayered polymeric material. The first seam 224 makes a portion of the first overlap area 258 adhere to the second planar member 222. The second seam 226 is spaced from the first seam 224 and makes a portion of the first peripheral flange 262 adhere to the second planar member 222.
