Abstract:
Forming webs and packages are provided having improved sealability to peelable lidstocks. The thermoformed containers (12) may have a mouth (14) having an opening and a flange being disposed about the opening, the flange formed from a forming web and having a thickness greater than about 12 mils and up to about 80 mils. The forming web may have a base layer (20) with a skim coating (24) thereon, a portion of the skim coating being on the flange having a skim coating thickness from about 2 mils to about 8 mils. A peelable lid (18) may include a film (28) with an inner lid sealant layer (26) which is sealed to the portion of the skim coating on the flange, the skim coating and inner lid sealant layer each having a common polyolefin majority component, the common polyolefin component being different than a majority component of the base layer.
Abstract:
An easy open and reclosable package is provided including a package body formed from a flexible film having a heat sealable inner layer, an outer layer, and a pressure sensitive adhesive disposed between the inner layer and the outer layer. A transverse end seam with a heat seal region is disposed across a transverse end of the package body and has at least a portion of a patterned die cut formed in the heat sealable inner layer therein, so as to allow a portion of the inner layer to delaminate and expose a portion of the pressure sensitive adhesive in the heat seal region when the transverse end seam is opened to form a substantially full opening in the transverse end of the package body. Flexible films and methods for fabrication of the flexible films and packages also are provided.
