A method of packaging a product within a bag includes the step of providing for at least one product security element to be present on or within the bag, in a region of where the bag will be sealed. The method also includes the steps of filling the bag with the product, and subsequently sealing the bag, using heat sealing apparatus, whereby the seal thus formed passes through at least a portion of the at least one product security element, thereby permanently heat sealing the product security element to the bag.

A lock for a food container of the type having a lower front flap and a partially-overlapping upper front flap, comprises an elongated body that has a tapered front end, a rear end, and a transverse stop disposed between the front end and the rear end. The front end of the elongated body has at least one angled resilient flange that has have a distal end adapted to flex towards the body temporarily in a compressed position when under force. Thereafter the at least one flange springs back to a natural position once inserted through front flap apertures of the container, inhibiting the removal thereof without breaking a perforated section or an otherwise frangible section of the container, thereby leaving evidence that the container has been opened. An embodiment that includes a clasp for receiving the front end of the body with a bag therebetween is also disclosed.

A storage and transport system for containers of liquid, comprising a detachable or separable handle component configured to securely hold or enclose a liquid-holding container and provide a carrying handle therefor; and a self-sealing receipt or label configured to receive printed information regarding the contents of the liquid-holding container, wherein the self-sealing receipt or label cooperates with the carrying handle to securely close the handle component around the liquid holding container, and wherein the self-sealing receipt or label is configured to provide visual evidence of tampering if the self-sealing receipt or label is separated from itself.

A wrapping material includes a substrate and a buffer layer, wherein the substrate has a first lateral edge and a second lateral edge, and the buffer layer has a third lateral edge and a fourth lateral edge. The buffer layer is stacked on the substrate. The first lateral edge of the substrate is tightly merged with the third lateral edge of the buffer layer, and the second lateral edge of the substrate is tightly merged with the fourth lateral edge of the buffer layer. A method of making a wrapping material includes: providing a substrate; stacking a buffer layer on the substrate; using a thermal cutting tool to cut the stacked substrate and buffer layer so that the substrate and the buffer layer are tightly merged at where they are cut as being melted by heat.

An easy-to-open gunny sack sewn by a single thread is disclosed. The easy-to-open gunny sack minimizes the costs of sewing a gunny sack through single thread sewing, allows a user to easily open the sack, prevents a sewing-finished section formed by single thread sewing from being easily loosened, and allows the user to easily identify an opening identification tape and to open the sack using the opening identification tape. The easy-to-open gunny sack allows a clip tape (20) to cover at least one of upper and lower ends of a sack portion, allows a single-thread sewing portion (10) by single thread sewing to be formed around the covered portion, allows an extended clip tape portion (21) formed by extension of the clip tape to be formed at both sides of the single-thread sewing portion (10), and allows an anti-loosening means to be provided at the extended clip tape portion (21) of the end portion placed in a sewing proceeding direction.
