    摘要: The specification discloses a multilaminar paperboard composite having improved recyclability and methods for forming and recycling the paperboard composite. The paperboard composite comprises a paperboard substrate having two surfaces, a highly alcoholized polyvinyl alcohol binder layer adjacent at least one surface of the paperboard substrate and a polyethylene polymeric layer bound to the polyvinyl alcohol layer. The highly alcoholized polyvinyl alcohol layer is present in an amount of from about 2 to about 12 pounds per 3000 square feet of substrate.

    摘要: A method and an apparatus for testing the adhesion between the polyethylene coating and paperboard stock of polyethylene coated paperboard stock, such stock typically used in forming milk and fruit juice cartons. A normally open ended pressure chamber is closed by clamping a piece of polyethylene coated paperboard over its open end. The coating facing the pressure chamber is cut completely through to form an opening. Air of a predetermined value is introduced into the pressure chamber. The opposite coating will form a bubble, indicating delamination, if the integrity of the adhesion between the polyethylene coating and the paperboard is poor. The air pressure at which delamination occurs is then used to quantify adhesion.

    摘要: A method of improving heat-seals for polyolefin polymers which are coated onto a paperboard substrate. The method obviates the need for use of a curable bonding agent. The materials are exposed to high energy radiation prior to formation of the heat seal to induce crosslinking of the poller and thereby increase the average molecular weight of same.

    摘要: A dual ovenable paperboard based structure which contains a food contact resin layer. The resin layer in direct contact with the ovenable food product exhibits superior food release properties, grease and oil resistance, and resistance to warpage even after extended periods of time following oven heating. The unique laminate is formed via coextrusion coating techniques on conventional coextrusion equipment at conventional temperatures. The resulting product has a high degree of adhesion between the paperboard and the polymethylpentene food contact layer, and is capable of being utilized for forming pressed or locked corner food trays which can be subjected to oven cooking temperatures.
