紙餐盒是指制作紙盒的材料，一般為一次性紙餐盒，使用方便，成本低，在餐飲業得到廣泛應用。由于使用紙張材料，可回收，可埋或燃燒，但不造成嚴重的環境污染，具有較高的環保價值。下面，來說下，紙餐盒包裝運輸貯存及性能測試方法。

Paper lunch boxes refer to the materials used to make paper boxes, generally disposable paper lunch boxes, which are widely used in the catering industry due to their convenient use and low cost. Due to the use of paper materials, which can be recycled, buried or burned, but do not cause serious environmental pollution, it has high environmental value. Next, let's talk about the packaging, transportation, storage, and performance testing methods for paper lunch boxes.

一、一次性紙餐盒的包裝和標識應按照GB/T10342的規定進行，一般為內外兩層，包裝應整齊，數量準確，或按訂貨合同的要求進行。內包裝材料應清潔、無毒、無異味、防塵、防水。應在包裝盒上附上解釋性標簽，具體說明如下：

1、 The packaging and identification of disposable paper lunch boxes should be carried out in accordance with the provisions of GB/T10342, generally with two layers inside and outside. The packaging should be neat and accurate in quantity, or in accordance with the requirements of the ordering contract. The inner packaging material should be clean, non-toxic, odorless, dustproof, and waterproof. An explanatory label should be attached to the packaging box, with specific instructions as follows:

1、產品名稱、型號、注冊商標、生產許可證和衛生許可證編號。

1. Product name, model, registered trademark, production license, and hygiene license number.

2、生產制造廠名、產地、批號或生產活動日期、有效期。

2. Name of the manufacturer, place of origin, batch number, or date of production activity, expiration date.

3、檢驗合格的標志和標準規范。

3. Mark and standard specifications for qualified inspection.

二、餐盒、紙板和紙張應妥善存放，以防止雨雪和地面潮濕的影響。

2、 Dining boxes, cardboard, and paper should be properly stored to prevent the impact of rain, snow, and moisture on the ground.

三、在運輸、儲存過程中，有關單位應當嚴格防止重金屬粉塵的污染。

3、 During transportation and storage, relevant units should strictly prevent pollution by heavy metal dust.

四、未開封批次產品的保質期不得超過1年。過期產品應按（3.2）的要求重新檢驗，符合標準的方可使用。紙餐盒性能的測定方法如下：

4、 The shelf life of unopened batches of products shall not exceed 1 year. Expired products should be reinspected according to the requirements of (3.2), and those that meet the standards can be used. The method for measuring the performance of paper lunch boxes is as follows:

1、容積測定。

1. Volumetric measurement.

在室溫下用1000mL測量缸，將相應體積的水入紙餐盒、大餐盒600mL，中餐盒500mL，小餐盒400mL，目視檢查無溢水合格。

Using a 1000mL measuring cylinder at room temperature, pour the corresponding volume of water into a paper lunch box, a large lunch box of 600mL, a Chinese lunch box of 500mL, and a small lunch box of 400mL, and visually inspect whether there is any water spillage.

2、耐水試驗。

2. Water resistance test.

將紙制飯盒放在紙板（或漿板）上，倒入溫度（90±5）℃的5％NaCl水，加入1～2滴甲基紅指示劑溶液，高度不應低于20mm。1小時后倒水，觀察背面及兩側是否有滲漏痕跡，如無滲漏痕跡則合格，否則判定不合格。

Place a paper lunch box on a cardboard (or pulp board), pour 5% NaCl water at a temperature of (90 ± 5) ℃, and add 1-2 drops of methyl red indicator solution. The height should not be less than 20mm. After 1 hour, pour water and observe whether there are leakage traces on the back and both sides. If there are no leakage traces, it is qualified, otherwise it is judged as unqualified.

3、耐油試驗。

3. Oil resistance test.

（150±10）°c食用油（花生油、豆油），用瓷勺加上（10±2）毫升的紙制午餐盒，然后將紙制午餐盒放在餐巾紙上。經過1h，觀察餐巾紙上是否有油點，如果沒有油點，是否合格，否則不合格。

(150 ± 10) ° C edible oil (peanut oil, soybean oil), add (10 ± 2) ml of paper lunch box with a porcelain spoon, and then place the paper lunch box on a napkin. After 1h, observe whether there are oil spots on the napkin. If there are no oil spots, check whether it is qualified, otherwise it is unqualified.

4、負重性能試驗。

4. Load bearing performance test.

將紙質飯盒平放在平板上，蓋上盒蓋。用金屬尺測量紙質飯盒的高度（甚至蓋子），精確到1毫米，然后倒入砂漿-沙子混合物。盒蓋合上后，放一塊200毫米’200毫米’3毫米的平板玻璃在上面。然后在平板玻璃中心放置3kg砝碼，當砝碼加載15s后立即取下砝碼和玻璃板，然后精確測量上述高度。

Place the paper lunch box flat on a flat plate and cover it. Use a metal ruler to measure the height of the paper lunch box (even the lid) to the nearest 1mm, and then pour in the mortar sand mixture. After the lid is closed, place a 200mm '200mm' 3mm flat glass on top. Then place a 3kg weight in the center of the flat glass, immediately remove the weight and the glass plate after loading the weight for 15s, and accurately measure the above height.

5、盒蓋折次試驗。

5. Box cover folding test.

將試樣盒蓋連續180°角開合15次，觀察與盒體連結處應無裂口、開裂。

Open and close the cover of the sample box at a continuous 180 ° angle for 15 times, and observe that the connection with the box body should be free of cracks and cracks.
