紙餐盒生產制作的4步工藝流程
來源:www.zgnjnu.com 發布時間:2022-11-11 瀏覽次數:122
一次性紙餐盒可用于餐廳、食堂、街頭小吃、美食包裝午餐盒、水果蔬菜盒及酒店商務用品等,使用非常方便,可高度降解,不會破壞環境。下面,具體來說下,紙餐盒生產制作工藝流程。
The disposable paper lunch box can be used in restaurants, canteens, street snacks, food packaging lunch boxes, fruit and vegetable boxes, hotel business supplies, etc. It is very convenient to use, highly biodegradable, and will not damage the environment. Next, specifically, the production process of paper lunch boxes.
1、制漿流程。
1. Pulping process.
紙餐盒的主要原料一般為漂白木漿,通常生產較多的商品級產品需要選擇進口木漿。中級產品可以選擇國內普通木材,紙漿、低檔產品可選用蔗渣漿、草漿、竹漿、蘆葦漿和白紙邊等短纖維漿。
The main raw material of paper lunch boxes is usually bleached wood pulp, and imported wood pulp is usually required for the production of more commercial products. Medium grade products can choose domestic ordinary wood, and pulp and low-grade products can choose bagasse pulp, straw pulp, bamboo pulp, reed pulp, white paper edge and other short fiber pulp.
這里,氣泡漿料和水輪機碎漿機作用。通過切絲對纖維進行皂化處理,提高纖維的結合能力,并添加相關輔料,提高紙漿餐具的防潮性能和成品的防水性能,還可以添加特定的相關材料。鋪料配漿后,調節原漿濃度,使其可以達到2%左右,以利原漿在網模上脫水成型。
Here, bubble slurry acts with the hydraulic turbine pulper. Saponify the fiber through cutting, improve the fiber's binding capacity, add relevant auxiliary materials, improve the moisture resistance of pulp tableware and the waterproof performance of finished products, and add specific related materials. After paving and slurry preparation, adjust the concentration of raw slurry to about 2%, so as to facilitate dewatering and molding of raw slurry on the mesh mold.
2、成型流程。
2. Forming process.
成型技術就是將原漿制成,具有一定不同形狀的半濕態紙漿餐具的毛坯。也就是經制漿工序設計出來的紙漿,在金屬材料模具上,脫水過程中形成濕紙漿餐具底層,這是紙制餐具生產過程中的關鍵工序,紙漿中95%左右的水分在形成過程中被去除。
Forming technology is to make raw pulp into semi wet tableware blanks with different shapes. That is, the pulp designed by the pulping process forms the bottom layer of wet pulp tableware on the metal material mold during dehydration, which is a key process in the production of paper tableware. About 95% of the water in the pulp is removed during the formation process.
因此,這一過程的產品質量、能耗都很高消耗、生產效率的提高和破碎率起著決定性的作用。成型質量取決于成型機、成型方式、模具結構以及原漿質量和質量因素。
Therefore, the product quality and energy consumption in this process are very high, and the improvement of production efficiency and crushing rate play a decisive role. The molding quality depends on the molding machine, molding method, mold structure, as well as the quality and quality factors of raw slurry.

3、模壓與烘干。
3. Molding and drying.
通過專用成型機成型,去除成型過程中紙漿餐具雛形中未去除的水分,降低干燥脫水成本的過程稱為成型。同時模壓可提高以及纖維間的結合力并增加濕紙模的強度。
The process of forming by a special forming machine to remove the water not removed from the pulp tableware prototype during the forming process and reduce the drying and dehydration costs is called forming. At the same time, molding can improve the adhesion between fibers and increase the strength of the wet paper mold.
4、整型與切邊。
4. Integer and trimming.
該工藝采用熱模壓制成型,壓延,消除紙張網格成型時留下的網痕,使內外表面光滑,并根據不同客戶的使用要求對一定的壓力,還有文字和圖案。同時切掉餐具邊緣的毛刺,壓下便于一次性飯盒蓋折疊的壓痕打開。
The process adopts hot die pressing and calendering to eliminate the mesh marks left by the paper grid forming, and make the internal and external surfaces smooth. According to the use requirements of different customers, certain pressure is applied, as well as words and patterns. At the same time, cut off the burrs on the edge of the tableware, and press down the indentation that is convenient for folding the disposable lunch box cover to open.
