Advantages of paper plastic composite bag

　　1、高强度:内层为PP或PE编织布，外层为精制复合纸，中间为复合塑料，本产品具有很强的耐穿、抗撕裂特性。

　　1. High strength: the inner layer is PP or PE woven cloth, the outer layer is refined composite paper, and the middle is composite plastic. This product has strong wear resistance and tear resistance.

　　2、外形美观:采用黄色或白色牛皮纸，三色印刷，外观韩国。

　　2. Beautiful appearance: yellow or white kraft paper, three color printing, Korean appearance.

　　3、防滑性好:选用防滑度在25度以上的纸张制造，便于堆放。

　　3. Good skid resistance: it is made of paper with a skid resistance of more than 25 degrees, which is convenient for stacking.

　　适用范围:

　　Scope of application:

　　Chemical raw materials, food additives, pharmaceutical additives, building materials, etc. are suitable for paper plastic composite bag packaging industry.

　　1. 磁导率

　　1. permeability

　　真空法需要五袋,袋/实际内容或类似的内容,热密封(见生产过程使用一个热条件)架,在压力容器试验后到相应的有色溶液(水)用墨水补充道,有色样品架完全,固定架覆盖容器,开始27真空kpa,保证为1分钟,观察实验袋有泡沫,实验后打开实验样品观察是否有渗水现象。

　　The vacuum method requires five bags, bags / actual contents or similar contents, thermal seal (see the production process using a thermal condition) rack, after pressure vessel test to the corresponding coloured solution (water), ink is added, the coloured sample rack is complete, the fixed rack covers the container, the starting 27 real empty kPa is guaranteed for 1 minutes, observe the experimental bag has foam, after the experiment opens the experimental sample to observe whether there is water seepage phenomenon.

　　2. 耐压函数

　　2. Withstand voltage function

　　取5个袋子，将袋子装一半左右的水，并进行热封(参照热封条件下采用的生产工艺)。将样品逐一放在上下板之间。实验时上下板应水平，不变形。与袋子的接触面应润滑。上下板的面积应大于实验袋。根据表3，将重量加1分钟(载荷为上压板重量与重量之和)。

　　Take 5 bags, fill half of the bag with water, and heat seal it (refer to the production process adopted under the condition of heat sealing). Place the samples between the upper and lower plates one by one. During the experiment, the upper and lower plates should be horizontal without deformation. The contact surface with the bag shall be lubricated. The area of the upper and lower plates shall be larger than that of the test bag. According to table 3, add the weight for 1 minute (the load is the sum of the weight of the upper platen and the weight).

　　3.删除函数

　　3. Delete function

　　取5个袋子，将袋子装上大约一半的水，并热封(参照热封条件所采用的生产工艺)，样品按表4的高度放在平整、坚硬的地面上(如水泥地面)。不可损坏视力。

　　Take 5 bags, fill the bag with about half of the water, and heat seal it (refer to the production process adopted for heat sealing conditions). Place the sample on a flat and hard ground (such as cement ground) according to the height in Table 4. Do not damage your vision.
