Some companies (e.g. Old Hickory Clay) use this as an alternative to shrink-wrapping every pallet of bagged materials (for environmental reasons for example). This wood derivative material is very sticky and behaves like a glue. However it redissolves quickly when whetted. Dark hard particles of this glue can be a concern in batching operations where they fall into the mix. However in a pugmill the particles dissolve during movement through the barrel and are not visible in the extruded product.
