来源:www.sdynbz.com 发布时间:2022-10-20 浏览次数:122
一次性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。下面来说下一次性纸餐盒性能的参考测定方法。
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。一次性纸餐盒性能的测定方法如下:
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、容积测定。
1. Volumetric determination.
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。
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 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 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、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),准确到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,然后准确测量上述高度。
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 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.
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,更为详细的内容可以来我们网站咨询!
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.
