A method of producing a wrapped package comprising of the wrapper material sealed around a product in a manner as to inflate the package to provide evidence of tampering if the seal or wrapping has been broken. It is known to wrap items such as chocolate bars within wrappers which have a single longitudinal seal, and two end seals. These wrappers may be tampered with and foreign compounds or objects may be introduced to the package and its contents without the knowledge of a consumer before ingestion of the contents. The present invention seeks to ameliorate one or more of the abovementioned disadvantages.
