Advantages of paper plastic composite bag

　　1、高強度:內層為PP或PE編織布，外層為精制復合紙，中間為復合塑料，本產品具有很強的耐穿、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、外形美觀:采用黃色或白色牛皮紙，三色印刷，外觀韓國。

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

　　3、防滑性好:選用防滑度在25度以上的紙張制造，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.

　　適用范圍:

　　Scope of application:

　　化工原料、食品添加劑、醫藥添加劑、建筑材料等均適用于紙塑復合袋包裝行業。

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

　　1. 磁導率

　　1. permeability

　　真空法需要五袋,袋/實際內容或類似的內容,熱密封(見生產過程使用一個熱條件)架,在壓力容器試驗后到相應的有色溶液(水)用墨水補充道,有色樣品架完全,固定架覆蓋容器,開始27真空kpa,保證為1分鐘,觀察實驗袋有泡沫,實驗后打開實驗樣品觀察是否有滲水現象。

　　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. 耐壓函數

　　2. Withstand voltage function

　　取5個袋子，將袋子裝一半左右的水，并進行熱封(參照熱封條件下采用的生產工藝)。將樣品逐一放在上下板之間。實驗時上下板應水平，不變形。與袋子的接觸面應潤滑。上下板的面積應大于實驗袋。根據表3，將重量加1分鐘(載荷為上壓板重量與重量之和)。

　　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.刪除函數

　　3. Delete function

　　取5個袋子，將袋子裝上大約一半的水，并熱封(參照熱封條件所采用的生產工藝)，樣品按表4的高度放在平整、堅硬的地面上(如水泥地面)。不可損壞視力。

　　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.
