    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a wooden tray friendly to environment wherein it can be incinerated without generating a toxic gas and a performance for returning to soil when buried in the soil is provided.
      SOLUTION: The method for manufacturing the wooden tray is composed as follows: a log of a specific length is practically processed into a rectangular state by sawing axially and then sliced to a thickness of 1.0 to 1.5 mm by using a slicer (process A); an obtained sheet-like lumber is laminated and pressed for a specific time with a press device to remove twist of each sheet-like lumber (process B); thereafter, cutting is carried out conforming to a size of a tray to be prepared (process C); the sheet-like lumber after cutting is heat press molded with a press molder in which a male mold and a female mold for tray molding are installed (process D); and a coating layer having a water proofing property and comprising a biodegradable material capable of being decomposed by microbe is provided at least on an inside surface of the obtained wooden tray (process E).

    • 要解决的问题:提供一种制造木质托盘的方法,其可以在不产生有毒气体的情况下被焚烧,并且在埋设在土壤中时返回土壤的性能。 解决方案:制造木质托盘的方法如下:通过轴向锯切将具体长度的对数实际上加工成矩形状态,然后通过切片机(方法A)切成1.0至1.5mm的厚度。 用压制装置将得到的片状木材层压并压制一段特定时间,以除去每个片状木材的扭曲(方法B); 之后,进行与要制备的盘的尺寸一致的切割(工序C)。 切割后的片状木材用压模机进行热压成型,其中安装有阳模和用于托盘成型的阴模(工艺D); 并且至少在所获得的木质托盘的内表面上提供具有防水性并且包含能够被微生物分解的生物降解材料的涂层(方法E)。
