A wrapper for a smoking article has a base web and a plurality of elements each having at least a pair of patch areas where diffusivity is in the range of 0 to about 0.2 cm/sec. Patches of adjacent elements are circumferentially offset from one another along the axis of a smoking article. The add-on material can be applied by gravure printing in a single pass in a chevron pattern such that an apex of the element is co-linear with substantially symmetrically spaced points on a trailing, outer edge of an adjacent element. Testing elements may be simultaneously printed with the add-on material to monitor diffusivity and/or presence of add-on material.

Herbage such as trimmed Cannabis flowers have a reflective coating that sparkles and improves shelf life. The invention includes a first coating of a first Cannabis plant extract including at least 60%-98% Tetrahydrocannabinol (THC) that forms a hardened layer on the dried herbage to mechanically preserve the shape of the herbage and enables handling and grinding of the herbage. A second coating of a second Cannabis plant extract, including at least 90-99% Tetrahydrocannabinolic acid (THCa) forms crystals, or “diamonds”, that are embedded in the first coating to improve aesthetics by reflecting light. The crystals improve shelf life by reducing absorption of light by the herbage. The weight sum of the combined coatings are in a particular ratio to the herbage. This ratio is between 1:4 and 2:1 on a weight to weight basis to cause the herbage to sparkle, to improve shelf life, and to enable grinding without sticking.

An aerosol generating substrate element includes an aerosol generating substrate comprising a glycerine content of between about 10% and about 30% and at least one paper layer circumscribing the aerosol generating substrate. The paper layer has a thickness in a range from about 78 micrometers to about 160 micrometers. At least about 80% of the aerosol generating substrate circumference is circumscribed by less than two paper layers.

An aerosol generating substrate element is circumscribed by exactly two paper layers that do not extend beyond an aerosol generating substrate. The aerosol generating substrate includes from about 10% to about 30% glycerine by weight. The first paper wrapper and the second paper wrapper have a combined thickness in a range from about 60 micrometres to about 200 micrometres. The first paper wrapper does not overlap itself and a second paper wrapper does not overlap itself.
