Question:

How should the packing tape be printed

What should I pay attention to, such as whether it should be printed on the inner surface or the outer surface? Also, can the pure transparent packing belt be printed? What are the special requirements for ink? Will increase the cost, etc., we sincerely hope that your heroes.

Answer:

Plastic Machinery Co., PET packing belt production line adopts 100% bottle waste as raw material, through the drying process and the specific equipment, production of qualified products of PET packing belt, anti blocking strength index reaches the industry standard. Not only has realized the low cost, enhanced the market competition ability, but also expanded the plastic recycling market, has stepped out a new road for the sustainable development.This set of equipment is mainly composed of automatic feeding machine, dryer (or dehumidifying device), extruder, mould, filter, water tank, traction machine, oven, drawing unit, heat setting box and winder equipment assembly.
First of all, the extruder temperature control is generally between 250 and 280 degrees centigrade. The next is cooling, strip out the head temperature is very high, to immediately enter the water cooling, because of isotactic polypropylene in acute cold conditions easily generated has crystal structure, molecular structure of paracrystals was loose. In this way, the strap is easy to stretch and obtain high quality products. Then, the tensile and tensile purposes are to increase the longitudinal strength of the strap and reduce the elongation. Tension must be carried out in boiling water, usually by one stretch. Finally, the embossing, stretching after the packaging belt, after two patterns of pressure roller, it will be pressed on the pattern, its role is to increase friction in use, do not slip, from the appearance of looking handsome.
Want to print a good pack of words, three can not be less:1., with the belt before embossing, the blank surface must be smooth and uniform, not one side thick, one side thin.2., the production of printing wheels to be precise, smooth and smooth surface, easy to scrape ink, ink should be thick and shade.3., the packing belt before and after the fixed to be accurate, keep the printing wheel and packing belt between not too big jitter, drive must be stable.
