摘要:
Provided are a flame-proof linerboard and a flame-proof corrugated paperboard in which with a small coating amount, a flame-proof layer is formed on the surface of a general linerboard so as to reduce penetration of the flame-proofing agent, and which are thus low in cost and exhibit high flame-proof performance. A flame-proof corrugated paperboard (21) is produced which includes, as a linerboard (15), a flame-proof paper including a paper layer (11), a flame-proof layer (12) containing a flame-proofing agent and a polymer having a molecular weight of 8,000 or more and 10,000,000 or less, and an overcoat layer (13) for protecting the flame-proof layer (12), the overcoat layer (13) being disposed closer to the surface of the corrugated paperboard than the flame-proof layer (12) is.

A water-dispersible sheet is described that maintains water dispersibility while providing suppressed time degradation of the tacky adhesiveness of a tacky adhesive layer. The water-dispersible sheet has a paper substrate with a multilayer structure. One layer of the multilayer structure is an inner layer that is not in contact with the tacky adhesive layer. Another layer is a surface layer that is in contact with the tacky adhesive layer. The layers independently include mixed pulps of a wood pulp and a refined pulp with an α-cellulose content of 88 % by weight or more. The weight ratio of the layers and the beating degree of the mixed pulps are set in the specific ranges.
摘要:
The present disclosure relates to a paper cup comprising a first coating comprising a polyethylene copolymer on a first surface of the paper cup and optionally a second aqueous-based coating on a second surface of the paper cup. In some embodiments, the first coating is on an inside surface of a bottom portion of the paper cup, and the second aqueous-based coating is on an inside of a side portion of the paper cup. The present disclosure also relates to methods of making the paper cups disclosed herein.
摘要:
The present invention relates to a coated paper product and method for making the coated paper product. The product comprises a paper substrate, which can be of a low quality, that is coated with at least two layers of coating in one embodiment. A first coating layer is applied to the front and back sides of the paper substrate before a second coating layer is applied. The first coating layer comprises titanium dioxide, an aluminum silicate, calcium carbonate, clay and a binder. The second coating layer comprises hollow spherical particles, which provides the coating with an improved ability to spread while improving the coverage and formation of the coating layer, and also comprises a printing additive, titanium dioxide and a binder.

This invention relates to a high temperature microwave susceptor structure comprising a microwave interactive material of carbon with a naturally occurring polymer or derivative and a base layer of a high temperature paper.
摘要:
This invention relates to an apparatus and method for enhancing extruded polyethylene terephthalate (PET) film adhesion to a cellulosic substrate. Such structures of this type, generally, use specialized primers which are applied in-line on the extruder such that the adhesion of PET to the cellulosic substrate can be greatly increased. This is accomplished by improvement of the chemical bond between the polymer film and substrate/primer.
摘要:
This invention relates to substrates for paperboard packaging having a press-applied barrier coating. Such structures of this type, generally, reduce the edgewick in the paperboard package such that catastrophic failure of the paperboard package is substantially reduced.
摘要:
The present invention is a photographic paper which includes a paper sheet with a polyolefin resin layer on each surface of the paper sheet. The photographic paper includes a print retaining antistatic layer having a dry coverage of from 80 mg/m.sup.2 to 1000 mg/m.sup.2 on one of the free surfaces of the polyolefin layers. The print retaining antistatic layer includes a smectite clay, and a polymeric binder wherein the polymeric binder can sufficiently intercalate inside or exfoliate the smectite clay. The photographic paper can include a silver halide light sensitive emulsion layer on the other free surface.
