一次性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(yè)得到廣泛應(yīng)用。由于使用紙張材料，可回收，可埋或燃燒，但不造成嚴(yán)重的環(huán)境污染，具有較高的環(huán)保價值。下面來說下一次性紙餐盒性能的參考測定方法。

Disposable paper lunch boxes refer to the materials used to make paper boxes. They are generally disposable paper lunch boxes, which are easy to use and low in cost, and are widely used in the catering industry. Due to the use of paper materials, they can be recycled, buried or burned, but do not cause serious environmental pollution, so they have high environmental value. The following is the reference measurement method for the performance of the next disposable paper lunch box.

未開封批次產(chǎn)品的保質(zhì)期不得超過1年。過期產(chǎn)品應(yīng)按（3.2）的要求重新檢驗，符合標(biāo)準(zhǔn)的方可使用。一次性紙餐盒性能的測定方法如下：

The shelf life of unopened batch products shall not exceed 1 year. Expired products shall be re inspected according to the requirements of (3.2), and those conforming to the standards can be used. The performance of disposable paper lunch box is determined as follows:

1、容積測定。

1. Volumetric determination.

在室溫下用1000mL測量缸，將相應(yīng)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。

At room temperature, use a 1000mL measuring cylinder to pour the corresponding volume of water into the paper lunch box, big lunch box 600mL, Chinese lunch box 500mL and small lunch box 400mL. It is qualified if there is no overflow through visual inspection.

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(yīng)低于20mm。1小時后倒水，觀察背面及兩側(cè)是否有滲漏痕跡，如無滲漏痕跡則合格，否則判定不合格。

Place the paper lunch box on the cardboard (or pulp board), pour 5% NaCl water with a temperature of (90 ± 5) ℃, and add 1~2 drops of methyl red indicator solution. The height should not be less than 20mm. Pour water one hour later, and observe whether there is leakage trace on the back and both sides. If there is no leakage trace, it is qualified, otherwise it is determined 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(jīng)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 paper lunch box with a porcelain spoon, and then put the paper lunch box on the napkin. After 1h, observe whether there is oil spot on the napkin. If there is no oil spot, check whether it is qualified, otherwise it is unqualified.

4、負(fù)重性能試驗。

4. Load bearing performance test.

將紙質(zhì)飯盒平放在平板上，蓋上盒蓋。用金屬尺測量紙質(zhì)飯盒的高度（甚至蓋子），準(zhǔn)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(dāng)砝碼加載15s后立即取下砝碼和玻璃板，然后準(zhǔn)確測量上述高度。

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

5、盒蓋折次試驗。

5. 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(jié)處應(yīng)無裂口、開裂。

Open and close the sample box cover at an angle of 180 ° for 15 times, and observe that there should be no cracks or cracks at the connection with the box body.

紙餐盒的包裝和標(biāo)識應(yīng)按照GB/T10342的規(guī)定進(jìn)行，一般為內(nèi)外兩層，包裝應(yīng)整齊，數(shù)量準(zhǔn)確，或按訂貨合同的要求進(jìn)行。內(nèi)包裝材料應(yīng)清潔、無毒、無異味、防塵、防水。應(yīng)在包裝盒上附上解釋性標(biāo)簽，更為詳細(xì)的內(nèi)容可以來我們網(wǎng)站http://www.ubzi.cn咨詢！

The packaging and identification of paper lunch boxes shall be carried out in accordance with the provisions of GB/T10342, generally in two layers, the packaging shall be neat and the quantity shall be accurate, or according to the requirements of the order contract. The inner packaging materials shall be clean, non-toxic, odor free, dust-proof and waterproof. An explanatory label should be attached to the packing box.
