摘要： A multi-layered product having an embossed interior layer is disclosed along with a method of making the product. The multi-layered product has a first layer with an interior surface, a second layer with an interior surface, and a third layer sandwiched between the first and second layers. The third layer has a first surface and a second surface, and has a thickness there between. The third layer is embossed into a waffle pattern having a plurality of protrusions and a plurality of recesses. Each of the plurality of protrusions and recesses is adjacently aligned and horizontally offset from one another. The plurality of protrusions form a horizontal plane, at the first surface, which is positioned above a horizontal plane formed by the plurality of recesses, at the first surface. The product also has an adhesive which secures the three layers together.

摘要： The invention discloses an environment-friendly straw paper and a preparation method thereof, and a manufacturing process of a paper straw, wherein the straw paper comprises a fibrous layer, barrier coating layers are respectively arranged on both sides of the fibrous layer, a heat-sealable coating layer is arranged outside of each of the barrier coating layers, and the heat-sealable coating layers can be bonded by heat- sealing. The straw paper has the following advantages: no wet strength agent is needed, its index parameters meet the requirements of food packaging paper, and through the optimization of the structure of the fiber composition, the control of the water content and the control of the stiffness of the base paper, the paperboard meets the process requirements of being able to roll up with a small radius of curvature and be rolled into a tubular shape with enough flexibility, the index of water resistance is that the water absorption value is not more than 10 g/m2 for 30 min, and the paperboard can maintain good stiffness even after being soaked for a long time, so that the straw paper is completely recyclable, degradable, repulpable and compostable; in addition, the straw paper is also characterized by high bulk and stiffness, has zero plasticity and light weight, and has excellent properties such as good barrier properties, heat sealability and microwave heatablity.
