一次性紙餐盒是指制作所述紙飯盒所用的材料為紙材料的餐盒，一般為一次性紙飯盒，其使用方便，成本低廉，已廣泛運用于餐飲行業(yè)中。由于采用紙材料制作，因而既可以回收使用，又可以通過掩埋或燃燒等方式處理，而不致于造成嚴重的環(huán)境污染，具有較高的環(huán)保價值。那么一次性紙餐盒的檢驗規(guī)則包含什么呢？

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?

以一次交貨為一批，餐盒紙板的樣本單位為令或卷，紙餐盒的樣本單位為個。

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.

供方應保證所供應的餐盒紙板或紙餐盒符合本標準的要求，每卷筒(令、箱)應附質量合格證一份。

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.

交收檢驗項目為相關的規(guī)定，并按GB/T2828進行。交收檢驗抽樣方案、檢查水平、合格質量水(AQL)及批質量判定按表5的規(guī)定，試樣的采取應按GB/T450進行。

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.

供方應保證所提供的產品符合衛(wèi)生指標的要求，投產前該產品應進行一次毒理檢驗，毒理檢驗結果符合GB15193.1要求的方可投產。在工藝條件、原材物料穩(wěn)定的連續(xù)生產的條件下，每三個月應進行一次衛(wèi)生指標的測定。若工藝條件或其它條件有變動時，應隨即進行測定。

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.

需方有權按本標準的規(guī)定進行驗收，如對批質量有異議，應在到貨后三個月內通知供方共同復驗。如不符合本標準的要求，應判批不合格，由供方負責處理；若符合本標準要求，則由需方負責處理。

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.

紙餐盒使用性能的測定方法：

Method for measuring the performance of paper lunch boxes:

容積測定

Volume measurement

在常溫下用1000mL的量筒，量取相應體積的水倒入紙餐盒中，大號餐盒600mL、中號餐盒500mL、小號餐盒400mL，目測應無水溢出即為合格。

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.

耐水試驗

Water resistance test

將紙餐盒平放在紙板(或漿板)上，倒入溫度(90±5)℃、濃度約5%的NaCl水，再加甲基紅指示液1～2滴，高度不應低于20mm。1h后將水倒出，觀察背面、兩側是否有滲漏痕跡，若沒有發(fā)現滲漏痕跡即為合格，反之判為不合格。

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.

耐油試驗

Oil resistance test

將(150±10)℃的食用油(花生油、豆油)，用瓷匙加(10±2)mL于紙餐盒中，再將紙餐盒放在一張餐巾紙上。1h后觀察餐巾紙上是否有油點，如無油點則為合格，反之為不合格。

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.

負重性能試驗

Load bearing performance test

將紙餐盒平放在平板上蓋好盒蓋，用金屬尺測量紙餐盒的高度(連蓋)，精確至1mm。然后倒入漿砂混合物。蓋好盒蓋后，在上面放一塊200mm′200mm′3mm的平板玻璃。再將3kg砝碼置于平板玻璃中央，負重15s時立即取下砝碼及玻璃板，再精確測量上述高度。用下式計算試樣的負重性能值：

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：對于各種型號紙餐盒所用的漿砂混合物具體如下：

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

大號餐盒(600mL)：250mL水、50g紙漿及200g砂子；

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

中號餐盒(500mL)：200mL水、40g紙漿及160g砂子；

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

小號餐盒(400mL)：150mL水、30g紙漿及120g砂子。

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

A5盒蓋折次試驗

A5 box cover folding test

將試樣盒蓋連續(xù)180°角開合15次，觀察與盒體連結處應無裂口、開裂。

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.
