a tray comprising a seal area; and
a lidding film removably coupled to the tray, the lidding film comprising:
a breakable layer comprising a reseal portion and an inner portion, wherein the reseal portion is separated from the inner portion by a break line, wherein the reseal portion of the breakable layer is sealed to the seal area of the tray, and wherein the reseal portion comprises a reseal surface;
a lidding layer coupled to the breakable layer; and
a pressure sensitive adhesive (PSA) layer arranged between the lidding layer and the reseal portion and the inner portion of the breakable layer, the PSA layer comprising a reseal portion configured to adhere to the reseal surface of the breakable layer and an inner portion corresponding to the inner portion of the breakable layer, wherein the reseal portion of the PSA layer is thinner than the inner portion of the PSA layer such that, when the lidding film is removed from the tray, the inner portion of the breakable layer remains coupled to the lidding layer while the reseal portion of the breakable layer remains sealed to the seal area of the tray; and
a tamper prevention portion, wherein the entire tamper prevention portion is positioned over the seal area;
wherein the reseal portion of the breakable layer is configured to separate from the inner portion of the breakable layer along the break line when the resealable container is initially opened such that the reseal portion of the breakable layer remains sealed to the seal area of the tray and the inner portion of the breakable layer remains coupled to the lidding layer; and
wherein the resealable container is configured to be resealed after opening by adhering the reseal portion of the PSA layer to the reseal surface of the breakable layer.
