A method for nano-depth surface activation of a PTFE-based membrane and relates to the technical field of polymer composites is disclosed. The method comprises the following steps: covering a functional surface of a PTFE-based nano functional composite membrane, performing surface activation treatment on a single surface of the membrane to which a bonding adhesive is applied, and migrating and complexing a high-toughness cold bonding adhesive tape on the membrane surface, with an activated structure layer, of the PTFE-based nano functional composite membrane through a mechanical adhesive applying device to form an adhesive-membrane complex. An extremely strong affinity and a high-strength bonding performance are generated between the membrane and the adhesive, and the adhesive-membrane complex is formed. Integration of membrane/adhesive bonding complexing, membrane/membrane bonding complexing and membrane/adhesive layer bonding is realized.

An examination of microwave oven-resistant sheets for heat-insulating foamed paper containers revealed that blisters occur in the containers in the course of microwave oven treatment. That is to say, the present invention addresses the problem of providing a sheet for heat-insulating foamed paper container such that no blisters occur during microwave oven treatment. The present inventors have found that the problem to be solved by the present invention can be solved by a method for producing a sheet for a heat-insulating foamed paper container, wherein an air gap of 150 mm or larger, a drawing speed of 65 m/minute or lower, and a polyethylene resin density of 923 to 930 kg/m.sup.3.

A method for producing a wood sheet that is between 0.6 and 0.8 mm thick, includes covering both surfaces with a matte crystal clear polyester film that is between 70 and 80 micrometres thick joined by thermopressing to the wood sheet. The wood sheet is sanded between the method steps to a thickness ranging from 0.6 to 0.8 mm, a matte polyester film with a thickness ranging from 70 to 80 micrometres is applied, they are then thermopressed at a controlled temperature and speed, and the wood sheet covered with the plastic material film is cold-pressed. The present invention also relates to a translucent wood sheet which allows illumination lamps having unique configurations to be produced.
