一次性纸餐盒是指制作所述纸饭盒所用的材料为纸材料的餐盒，一般为一次性纸饭盒，其使用方便，成本低廉，已广泛运用于餐饮行业中。由于采用纸材料制作，因而既可以回收使用，又可以通过掩埋或燃烧等方式处理，而不致于造成严重的环境污染，具有较高的环保价值。那么一次性纸餐盒的检验规则包含什么呢？

A disposable paper lunch box refers to a lunch box made of paper material, which is generally a disposable paper lunch box. It is easy to use and has low cost, and has been widely used in the catering industry. Due to the use of paper materials, it can be recycled and treated through burial or combustion, without causing serious environmental pollution, and has high environmental value. So what are the inspection rules for disposable paper lunch boxes?

以一次交货为一批，餐盒纸板的样本单位为令或卷，纸餐盒的样本单位为个。

Each delivery is considered as a batch, with the sample unit of cardboard for meal boxes being in rolls or rolls, and the sample unit of paper lunch boxes being in pieces.

供方应保证所供应的餐盒纸板或纸餐盒符合本标准的要求，每卷筒(令、箱)应附质量合格证一份。

The supplier shall ensure that the cardboard or paper lunch boxes supplied comply with the requirements of this standard, and each drum (bundle, box) shall be accompanied by a quality certificate.

交收检验项目为相关的规定，并按GB/T2828进行。交收检验抽样方案、检查水平、合格质量水(AQL)及批质量判定按表5的规定，试样的采取应按GB/T450进行。

The delivery inspection items are relevant regulations and shall be carried out in accordance with GB/T2828. The sampling plan, inspection level, qualified quality water (AQL), and batch quality judgment for delivery inspection shall be in accordance with Table 5, and the sampling of samples shall be carried out in accordance with GB/T450.

供方应保证所提供的产品符合卫生指标的要求，投产前该产品应进行一次毒理检验，毒理检验结果符合GB15193.1要求的方可投产。在工艺条件、原材物料稳定的连续生产的条件下，每三个月应进行一次卫生指标的测定。若工艺条件或其它条件有变动时，应随即进行测定。

The supplier should ensure that the products provided meet the requirements of hygiene indicators. Before production, the product should undergo a toxicological test. Only those whose toxicological test results meet the requirements of GB15193.1 can be put into production. Under the conditions of stable continuous production of process conditions and raw materials, hygiene indicators should be measured every three months. If there are changes in process or other conditions, the measurement should be carried out immediately.

需方有权按本标准的规定进行验收，如对批质量有异议，应在到货后三个月内通知供方共同复验。如不符合本标准的要求，应判批不合格，由供方负责处理；若符合本标准要求，则由需方负责处理。

The purchaser has the right to conduct acceptance according to the provisions of this standard. If there are any objections to the batch quality, they shall notify the supplier to jointly retest within three months after arrival. If it does not meet the requirements of this standard, it shall be judged as unqualified and handled by the supplier; If it meets the requirements of this standard, the purchaser is responsible for handling it.

纸餐盒使用性能的测定方法：

Method for measuring the performance of paper lunch boxes:

容积测定

Volume measurement

在常温下用1000mL的量筒，量取相应体积的水倒入纸餐盒中，大号餐盒600mL、中号餐盒500mL、小号餐盒400mL，目测应无水溢出即为合格。

At room temperature, use a 1000mL measuring cylinder to measure the corresponding volume of water and pour it into a paper lunch box. The large lunch box should have 600mL, the medium lunch box should have 500mL, and the small lunch box should have 400mL. If there is no water overflow, it is considered qualified.

耐水试验

Water resistance test

将纸餐盒平放在纸板(或浆板)上，倒入温度(90±5)℃、浓度约5%的NaCl水，再加甲基红指示液1～2滴，高度不应低于20mm。1h后将水倒出，观察背面、两侧是否有渗漏痕迹，若没有发现渗漏痕迹即为合格，反之判为不合格。

Place the paper lunch box flat on the cardboard (or pulp board), pour in NaCl water with a temperature of (90 ± 5) ℃ and a concentration of about 5%, and then add 1-2 drops of methyl red indicator solution. The height should not be less than 20mm. After 1 hour, pour out the water and observe if there are any signs of leakage on the back and both sides. If no signs of leakage are found, it is considered qualified, otherwise it is deemed unqualified.

耐油试验

Oil resistance test

将(150±10)℃的食用油(花生油、豆油)，用瓷匙加(10±2)mL于纸餐盒中，再将纸餐盒放在一张餐巾纸上。1h后观察餐巾纸上是否有油点，如无油点则为合格，反之为不合格。

Add (10 ± 2) mL of edible oil (peanut oil, soybean oil) at (150 ± 10) ℃ to a paper lunch box with a porcelain spoon, and then place the paper lunch box on a napkin. After 1 hour, observe if there are oil spots on the napkin. If there are no oil spots, it is considered qualified, and vice versa, it is considered unqualified.

负重性能试验

Load bearing performance test

将纸餐盒平放在平板上盖好盒盖，用金属尺测量纸餐盒的高度(连盖)，精确至1mm。然后倒入浆砂混合物。盖好盒盖后，在上面放一块200mm′200mm′3mm的平板玻璃。再将3kg砝码置于平板玻璃中央，负重15s时立即取下砝码及玻璃板，再精确测量上述高度。用下式计算试样的负重性能值：

Place the paper lunch box flat on a flat plate and cover the lid. Use a metal ruler to measure the height of the paper lunch box (with the lid connected) to the nearest 1mm. Then pour in the slurry sand mixture. After covering the box lid, place a 200mm '200mm' 3mm flat glass on top. Place a 3kg weight in the center of the flat glass, and immediately remove the weight and glass plate when the load is 15 seconds, and then accurately measure the above height. Calculate the load-bearing performance value of the sample using the following equation:

注：对于各种型号纸餐盒所用的浆砂混合物具体如下：

Note: For various types of paper lunch boxes, the specific slurry and sand mixtures used are as follows:

大号餐盒(600mL)：250mL水、50g纸浆及200g砂子；

Large lunch box (600mL): 250mL of water, 50g of pulp, and 200g of sand;

中号餐盒(500mL)：200mL水、40g纸浆及160g砂子；

Medium size lunch box (500mL): 200mL of water, 40g of pulp, and 160g of sand;

小号餐盒(400mL)：150mL水、30g纸浆及120g砂子。

Small lunch box (400mL): 150mL of water, 30g of pulp, and 120g of sand.

A5盒盖折次试验

A5 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 sample box cover at a continuous 180 ° angle for 15 times, and observe that there should be no cracks or cracks at the connection with the box body.
