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.
