• apertures in the web arranged in sets,
• adhesive labels applied to an external surface of the web so that each adhesive label fully covers a set of apertures and discrete areas of adhesive are exposed at an internal surface of the web, through the apertures,
• a seal in the machine direction of the web, wherein said seal is formed of overlapped edges of the web that are adhered to one another, and
• a seal in the cross-machine direction of the web, wherein said seal comprises the discrete areas of exposed adhesive.

A method for making a biodegradable package on a form-film-seal machine, said method comprising the steps of:

• a) providing a continuous web of a biodegradable material, said web having a machine direction and a cross-machine direction and comprising apertures arranged in a pattern of repeating sets along a cross-machine direction of the web;
• b) providing on the web discrete areas of exposed adhesive, wherein the discrete areas of exposed adhesive are formed by applying labels to the web so that each label fully covers a set of one or more apertures;
• c) forming a seal in the machine direction of the web by adhering overlapping edges of the web to one another;
• and
• d) forming seals in the cross-machine direction of the web using the discrete areas of exposed adhesive.
