Q:Features of PP packing belt
Strong adhesive force, large tensile force, light weight, corrosion resistance, beautiful appearance and high grade
Q:The packer does not have a packing belt
The electromagnet is not working properly. Check that the coil is burned out. If neither of them is abnormal, the electromagnet will not work. First check whether the electromagnet welding head is off. Should check whether the electromagnet displacement, or is blocked by the stolen goods, so that bullets can not move freely.

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.

Q:What types of Baling straps are used for packing?
Galvanized belt (also called iron straps). Steel is easy to rust in air and water, and the corrosion of zinc in the atmosphere was only the corrosion rate of steel 1/15 in the atmosphere, is the use of micro thick galvanized steel galvanized layer of protection against corrosion of steel.
Q:Do you have your bags ready before boarding?
Baggage checked, you can prepare your own packing belt, or packaged at the airport.Depending on the baggage, the choice is different.

PET plastic steel belt identification: the most important standard (not crisp, is to use clamps will be packaged with the middle of the pack, just sampling clamping, cracking, rupture is the most poor packing belt, lines should have been clear, color should be transparent, with small font size 7 in the package down to see this just clear, packing belt very good.
Q:What is the reason why the packing belt breaks easily?
Packing belt temperature settings are not suitable, summer should be around 450 degrees, in the northern winter to about 600 degrees;
Q:How should the packing tape be printed?
The characters on the packing belt are not printed on the back, but made directly. It is a belt with Chinese characters.
