Standardization domestic packaging industry behind the development of the packaging industry. Some standards and production unrealistically, content is still stuck at the level of a decade ago. For example, the "Container" standard was developed by the transport sector, "cement bags" standard building materials sector to develop, "geotextile" standard was developed by the textile sector, "woven" plastics department of standards and so on. Due to the lack of interest among woven products targeted and industry use, also known as snakeskin. Is a kind of plastic, packaging bags wholesale hand, the raw material is usually polyethylene, polypropylene and other chemical plastic raw materials. The main terms of bags: Plastic bags are polypropylene, polyethylene resin as the main raw material, extruded, drawn into flat yarn, and then weaving, the preparation, the bag is made. Foreign production is mainly polyethylene (PE), polyethylene (PE), is a thermoplastic resin polymerized ethylene obtained. Full consideration, there is not a unified, effective, taking into account the interests of standards. Woven bags in application fisheries mainly in fish bag, fish bags suggests that it is mounted fish bag, bags have been very good use of the fishermen to the various aspects of transportation and other fisheries.

What is the main process of screen printing process is that it is the needle it is mainly the screen printing process:?? Making the originals, making silk screen printing, printing, ink drying. ▼ 11. What is the tension meter? Tension meter is subjected to tensile force measurement instrument screen size of its internal mutual traction with the fixed screen between the contact body. Tension meter mechanical electronic type two, expressed in units of measurement of tension in N / cm. Tension can also be used to represent the relative values. Cm tension meter is represented by the relative value of a tension, a tension meter by its own weight so that the value of the screen sinking depth (mm) to calculate the tension value can be obtained directly from the dial, or indirectly from the control panel get. There are two kinds of tension meter manual and mechanical handling. Tension testing instrument is an important quality screen printing plate detection equipment. Plate requirements in order to get the tension in the stretching process should use or the stretching tension measurement wholesale hand bags, hand bags, packaging provided by Xiong Yu Xin Yu Xin plastic packaging plant.
