纸餐盒是指制作纸盒的材料，一般为一次性纸餐盒，使用方便，成本低，在餐饮业得到广泛应用。由于使用纸张材料，可回收，可埋或燃烧，但不造成严重的环境污染，具有较高的环保价值。下面，来说下，纸餐盒包装运输贮存及性能测试方法。

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、一次性纸餐盒的包装和标识应按照GB/T10342的规定进行，一般为内外两层，包装应整齐，数量准确，或按订货合同的要求进行。内包装材料应清洁、无毒、无异味、防尘、防水。应在包装盒上附上解释性标签，具体说明如下：

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、产品名称、型号、注册商标、生产许可证和卫生许可证编号。

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

2、生产制造厂名、产地、批号或生产活动日期、有效期。

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

3、检验合格的标志和标准规范。

3. Mark and standard specifications for qualified inspection.

二、餐盒、纸板和纸张应妥善存放，以防止雨雪和地面潮湿的影响。

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

三、在运输、储存过程中，有关单位应当严格防止重金属粉尘的污染。

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

四、未开封批次产品的保质期不得超过1年。过期产品应按（3.2）的要求重新检验，符合标准的方可使用。纸餐盒性能的测定方法如下：

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、容积测定。

1. Volumetric measurement.

在室温下用1000mL测量缸，将相应体积的水入纸餐盒、大餐盒600mL，中餐盒500mL，小餐盒400mL，目视检查无溢水合格。

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、耐水试验。

2. Water resistance test.

将纸制饭盒放在纸板（或浆板）上，倒入温度（90±5）℃的5％NaCl水，加入1～2滴甲基红指示剂溶液，高度不应低于20mm。1小时后倒水，观察背面及两侧是否有渗漏痕迹，如无渗漏痕迹则合格，否则判定不合格。

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、耐油试验。

3. Oil resistance test.

（150±10）°c食用油（花生油、豆油），用瓷勺加上（10±2）毫升的纸制午餐盒，然后将纸制午餐盒放在餐巾纸上。经过1h，观察餐巾纸上是否有油点，如果没有油点，是否合格，否则不合格。

(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、负重性能试验。

4. Load bearing performance test.

将纸质饭盒平放在平板上，盖上盒盖。用金属尺测量纸质饭盒的高度（甚至盖子），精确到1毫米，然后倒入砂浆-沙子混合物。盒盖合上后，放一块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砝码，当砝码加载15s后立即取下砝码和玻璃板，然后精确测量上述高度。

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、盒盖折次试验。

5. Box cover folding test.

将试样盒盖连续180°角开合15次，观察与盒体连结处应无裂口、开裂。

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.
