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(wù)用品等，使用非常方便，可高度降解，不會破壞環(huán)境。下面，具體來說下，紙餐盒生產(chǎn)制作工藝流程。

Disposable paper lunch boxes 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 degradable, and will not damage the environment. Next, specifically, the production process of paper lunch box.

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(chǎn)較多的商品級產(chǎn)品需要選擇進(jìn)口木漿。中級產(chǎn)品可以選擇國內(nèi)普通木材，紙漿、低檔產(chǎn)品可選用蔗渣漿、草漿、竹漿、蘆葦漿和白紙邊等短纖維漿。這里，氣泡漿料和水輪機(jī)碎漿機(jī)作用。通過切絲對纖維進(jìn)行皂化處理，提高纖維的結(jié)合能力，并添加相關(guān)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(guān)材料。鋪料配漿后，調(diào)節(jié)原漿濃度，使其可以達(dá)到2％左右，以利原漿在網(wǎng)模上脫水成型。

The main raw material of the paper lunch box is generally bleached wood pulp. Generally, it is necessary to choose imported wood pulp to produce more commercial products. Intermediate products can choose domestic ordinary wood, pulp and low-grade products can choose bagasse pulp, straw pulp, bamboo pulp, reed pulp, white paper edge and other short fiber pulp. Here, the bubble slurry and the hydraulic turbine pulper function. The saponification treatment of the fiber through shredding can improve the binding ability of the fiber, and add relevant auxiliary materials to improve the moisture-proof performance of the pulp tableware and the waterproof performance of the finished product. Specific relevant materials can also be added. 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(shù)就是將原漿制成，具有一定不同形狀的半濕態(tài)紙漿餐具的毛坯。也就是經(jīng)制漿工序設(shè)計(jì)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(chǎn)過程中的關(guān)鍵工序，紙漿中95％左右的水分在形成過程中被去除，因此，這一過程的產(chǎn)品質(zhì)量、能耗都很高消耗、生產(chǎn)效率的提高和破碎率起著決定性的作用。成型質(zhì)量取決于成型機(jī)、成型方式、模具結(jié)構(gòu)以及原漿質(zhì)量和質(zhì)量因素。

Forming technology is to make raw pulp into semi-wet pulp tableware blanks with certain 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 the dehydration process. This is the key process in the production process of paper tableware. About 95% of the water in the pulp is removed during the formation process. 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, the molding method, the mold structure, and the quality and quality factors of the raw slurry.

3、模壓與烘干。

3. Molding and drying.

通過專用成型機(jī)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(jié)合力并增加濕紙模的強(qiáng)度。干燥是用紙漿和餐具的純銅模具對紙漿和餐具的原型進(jìn)行加熱和蒸發(fā)，并在成型后除去剩余的水分，還具有殺菌功能。對整個干燥過程進(jìn)行合理的設(shè)計(jì)，以節(jié)約成本，已成為提高制漿餐具企業(yè)經(jīng)濟(jì)效益的主要途徑。

The process of forming by special molding machine to remove the water that is 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 wet paper mold. Drying is to heat and evaporate the prototype of pulp and tableware with the pure copper mold of pulp and tableware, and remove the remaining water after molding. It also has the function of sterilization. Reasonable design of the whole drying process to save costs has become the main way to improve the economic benefits of pulp and tableware enterprises.

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(wǎng)格成型時留下的網(wǎng)痕，使內(nèi)外表面光滑，并根據(jù)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。

This process uses hot die pressing and calendering to eliminate the mesh marks left by paper mesh forming, make the internal and external surfaces smooth, and put certain pressure on different customers according to their use requirements, as well as text 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.
