The disclosure relates to a top engaging carrier formed from a paperboard substrate having a first surface and an opposing second surface, with a polymer film laminated onto the first surface.

Carton and blank therefor

A paperboard structure including a paperboard substrate having a first major side and a second major side opposed from the first major side, and a coating layer on the first major side, the coating layer includes a polymer and talc, wherein the polymer includes at least one of poly(butylene succinate) and poly(butylene succinate-co-adipate).

Compostable paperboard structure and method for manufacturing the same

A coating for paperboard includes polyethylene outer layers and a polyethylene inner layer with calcium carbonate filler. In addition to the lower cost, benefits include a surprising better heat sealing behavior compared with a coating of polyethylene alone.

Heat sealable coating with filler

A coating for paperboard includes polylactic acid and an inorganic material. The inorganic material may be talc. The presence of the talc has a beneficial effect on extrusion processing behavior including lower melt temperature, lower head pressure, and lower motor load. Additionally, the presence of talc reduces edge weave and neck-in during extrusion coating processes.

Biopolymer coating for compostable paperboard packaging

A compound suitable for hydroclaving is disclosed, comprising polyester, polysulfone, and an epoxy-functional styrene-acrylate oligomer. In order for successful repetitious hydroclaving to be possible, the compound must also have a polysulfone content of greater than 45 weight percent of the compound.
