television show or other media franchise. For example, Imagination Farms has marketed produce with collectible Disney character stickers such as Toy Story and Finding Nemo under the Disney Garden brand, and Chiquita has marketed bananas with Minions stickers on them, along with a competition. Collecting Although the collecting of PLU labels as a hobby already existed for a while, it became widespread through social media presence and fashion designs that use fruit stickers. The popularity of the hobby was further increased by online catalogs and collector clubs. In addition to illustrations, important factors for collectors are compositions of these stickers and the type of product they are used on. Most popular materials for creating PLU code stickers are plastic film and paper, however cardboard, metallized film, wrapping tissue, and textiles are also known to be used. Environmental concerns Although PLU labels are recognized globally and most chain supermarkets use them, they sometimes cause rejection of the fruits and vegetables they are attached to from being accepted for composting disposal. Generally, they are not made of biodegradable material.
