many environmental protection bags are produced by waste paper, the technology will have several need to pay attention to:
for general dry cargo, it is recommended to use the waste or the waste, according to the grade A or B liner board paper technical indicators to control the production of base paper. Surface can dry noodles, also can not dry noodles, depending on want to print the patterns of the complex and advertising. Sheet can be quantitatively in 135 ~ 150 g/m2, 25 * 20 x 15 cm bags under weight up to 8 to 15 kg.
for goods need to bear a certain moisture, can also use the waste paper. Just on the basis of the above standard, add some wet strength agent 0. 5 ~ 1. 0%, wet strength reached 10 ~ 15% of the dry strength.
for meat or other wet goods, also can choose all the waste paper making shopping bags. This need in the process of paper pulp add or surface coated with environmental protection agent; Also can use the paper surface strength good liner board secondary spray water soluble, or degradation of resin.
in recent years, many domestic manufacturers, has developed the whole paper waste paper clip muscles. In writing, combined with textile principle between two layers of pulp added into water soluble yarn, this paper layer can achieve the strength of the four layers of kraft paper, can completely replace the ordinary cement bag paper. Similarly, single paper can use the shopping bag.
