Forming webs and packages are provided having improved sealability to peelable lidstocks. The thermoformed containers may have a mouth having an opening and a flange 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 with a skim coating 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 may include a film with an inner lid sealant layer 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.

A recloseable package is provided having a tamper-indicating element. The tamper-indicating element include one or more self-terminating shapes that form one or more chads after opening the recloseable package. Advantageously, the self-terminating shapes provide a simple, visual cue of graphical alignment in the seal to show the customer whether or not a package has been opened.

Tamper-indicating shapes for flexible recloseable packages

A package formed of a package material comprising a heat-sealable inner layer, an outer layer, and a pressure-sensitive adhesive disposed between the inner layer and the outer layer. The package may include a gusset with a center fold that divides the gusset into a first folded portion and a second folded portion. The package may further include a transverse heat-seal region extending across the gusset whereby the first folded portion is sealed to itself by mating surfaces of the heat-sealable inner layer and the second folded portion is sealed to itself by mating surfaces of the heat-sealable inner layer. The package may also include a patterned die cut formed in the heat-sealable inner layer, wherein at least a portion of the patterned die cut is adjacent to the transverse heat-seal region of the gusset so as to allow a portion of the inner layer to delaminate and expose a portion of the pressure-sensitive adhesive when the center fold is unfolded and the resealable pour spout is opened.
