Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seal having strength of a re-closed seal that is significantly lower than strength of an original, not-yet-opened seal, but high enough to provide a reliable seal in the re-closed state of the package.SOLUTION: A cold seal formed between a first and a second sealing portion of the reclosable package for food products, in which the bonding force of the cold seal to the first and the second sealing portion is greater than the bonding force within the cold seal, so that the cold seal is separated and partly adheres to the first sealing portion, and partly adheres to the second sealing portion when the seal is opened. The cold seal is provided with an initial opening force of preferably 2.5 to 4 N/15 mm, and opening forces for one or more re-closings of 0.5 to 2 N/15 mm, preferably 1 to 1.5 N/15 mm.
