Abstract: A stone paper includes a first material layer and a second material layer. The first material layer includes a first inorganic material, a first plastic material, and an additive, wherein the first inorganic material, the first plastic material, and the additive are mixed together. The second material layer is coextruded on at least one surface of the first material layer, and the second material layer includes a second inorganic material, a nonmetal thermoconductive material, and a second plastic material, wherein the second inorganic material, the nonmetal thermoconductive material, and the second plastic material are mixed together. A manufacturing method of a stone paper is also disclosed herein.

Abstract: A waterproof corrugated paper includes at least one stone paper medium and at least one stone liner paper, wherein the at least one stone paper medium includes a first fluting surface. A stone glue is utilized to adhere the at least one stone liner paper and several wave crests of the first fluting surface. The stone glue includes a linear polyolefin plastic material and an inorganic material. The linear polyolefin plastic material is 30 wt %-70 wt % based on the stone glue, and the inorganic material is 30 wt %-70 wt % based on the stone glue. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food. A manufacturing method, a manufacturing apparatus, and a usage of the waterproof corrugated paper are also provided in the present invention.

Abstract: A waterproof corrugated paper includes a stone paper medium, a stone glue, and at least two stone liner papers. The stone paper medium includes a first fluting surface and a second fluting surface. The stone glue is applied to wave crests of the first fluting surface and wave crests of the second fluting surface. The at least two stone liner papers are respectively attached to the first fluting surface and the second fluting surface by the stone glue applied to the wave crests of the first and second fluting surfaces, thereby allowing the stone paper medium to be located between the at least two stone liner papers. The stone paper medium, the stone glue, and the stone liner papers includes a linear polyolefin plastic material and an inorganic material. The waterproof corrugated paper provided by the present invention is waterproof and frost-resistant, which is adapted to package cooled or frozen food.

Abstract: A composite waterproof corrugated paper includes a stone paper medium and at least one stone liner paper. The stone paper medium has a first fluting surface and includes at least one first body layer and at least one adhesive layer which are coextruded. The first body layer includes a first surface. The adhesive layer is disposed on the first surface. The stone liner paper includes at least one second body layer and a supplementary layer which are coextruded. The supplementary layer is disposed on the second body layer and is attached to several wave crests of the first fluting surface, so that the stone paper medium adheres to the stone liner paper via the adhesive layer. A manufacturing method of the composite waterproof corrugated paper is also provided in the present invention.
