6results about "Coated paper substrate" patented technology

The present invention relates to the use of a paper substrate (11) in a high-quality, barrier-coated paper substrate (10) for providing good toughness, flexibility and oxygen barrier properties to a laminated packaging material and to packaging containers comprising the laminated packaging material. The barrier-coated paper substrate may also provide heat sealing capability to a laminated packaging material comprising it. The barrier-coated paper substrate (10; 23), is suitable in packaging of oxygen-sensitive food products.

The application discloses a preparation method of a large-capacity quick oil-absorbing paper towel for kitchens, and the oil-absorbing paper towel preparation method comprises the following steps: S1, providing a surface layer substrate, an intermediate layer substrate and a bottom layer substrate respectively; S2, treating the surface layer substrate in the step S1 to obtain a micro-nano roughened surface layer; S3, preparing a finishing liquid; S4, immersing and padding the micro-nano roughened surface layer obtained in the step S2 with the finishing liquid, and then carrying out baking and curing after drying to obtain a modified surface layer; S5, sequentially stacking the modified surface layer, the intermediate layer substrate and the bottom layer substrate, adopting point-like hot-pressing compounding, and cutting after cooling and shaping to obtain the large-capacity quick oil-absorbing paper towel for kitchens. Through the synergistic design of the three-layer gradient structure and the dual-function modified auxiliary agent, the excellent comprehensive oil-absorbing performance is realized. The overall preparation process of the application is mild, and the substrate is not damaged; the obtained fabric is soft, heat-resistant and can be mechanically extruded and regenerated for more than 50 times, which is significantly superior to the existing products.
