1.要看外包装。产品的包装、封口应整齐牢固,没有破损现象,包装上应印有生产企业的名称、生产日期、产品等级、采用标准号、执行的卫生标准号等完善的信息。2.要看定量(指分量或者张数够不够)。根据相关规定,一般是净含量50克至100克的商品,其负偏差不得超过4.5克,200克到300克的商品,不得超过9克。3.要看横向吸液高度。将水滴在上面看吸收速度怎样,速度越快说明吸水性越好。4.要看横向抗张指数。就是看纸的韧性怎样,使用时是否容易碎裂。纯木浆纸由于纤维长,故拉力大,韧性好,不易断。
1 depends on the packaging. Product packaging, sealing should be neat and solid, there is no damage, the packaging should be printed on the name of the manufacturer, the date of production, product level, the use of standard numbers, the implementation of health standards such as sound information. 2. To look at quantitative (referring to the amount or number of sheets is not enough). According to the relevant regulations, generally the net content of 50 grams to 100 grams of goods, the negative deviation of not more than 4.5 grams, 200 grams to 300 grams of goods, not more than 9 grams. 3 depends on the horizontal suction height. The water droplets in the absorption rate above what, the faster the better water absorption. 4 depends on the horizontal tensile index. Is how to look at the toughness of paper, the use of easily broken. Pure wood pulp as fiber length, so the tension, toughness, not easy to break.
