Product Description:

Application: Flame retardant polypropylene filler yarn is used as filling material in the manufacturing

of cables. The fillers are employed in multicore cables, being laid in the interstices of the cable cores

to make the assembled cable shaping round.

The color is available in light blue, natural white or other colors according to customer requirements.

As FR cable filler, it easily to ensure cables to pass the IEC60331, IEC60332-3 & BS6387 tests.

Q:What adhesive tape do you use?
Heavy weight wooden cases can be packaged in PET plastic steel belts and steel strips, in which the plastic steel belt is a new strapping belt instead of the steel belt. It is widely used in ceramics, cotton spinning, aluminum, building materials, tobacco and paper industry.
Q:What is the reason why the packing belt breaks easily?
For a long time, and do not pay attention to cleaning, resulting in packaging machine hot tongue on the dirt is too much, as long as sandpaper is used to rub off the stain on it;3, semi automatic packing automatic packing machine or the hot side, packaged hot melt zone is too small, the use of pliers correction;
Q:How should the packing tape be printed?
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's the reason why the packing belt breaks easily?
When the operator does not wait for the back of the pallet on the packing machine, the goods will be moved down and the hot melt surface has not been condensed
Q:What kind of joints are used in the packing belt
Iron buckle packing.The one-way tensioner ratchet, the packing tape tensioning, then pack joints placed a hasp, hasp and clamps make wrap two layer packing belt, and the tooth shaped hasp side teeth bump, bite strap does not cause the loose. Usually made of galvanized sheet iron buckle, the operation to choose to adapt according to the specifications of the metal packing belt type.
Q:What do you mean by the viscosity of the packing belt?
Pack by perm heating hot melt packing machine and stick together, then the joints are cooled down after the tension can be called adhesion (adhesion).
Q:Blue belt principle is what?
Blue will be packaged with packaging with heating to proper temperature in the air - water vapor to form a blue layer of the surface process.
Q:What's the difference between PP strapping and PET packaging
Pet packing belt is suitable for packing large and heavy materials, such as glass, steel, stone, brick and so on. It is more suitable for long distance transportation. The PP straps are suitable for packing cartons or other lighter objects. The steel belt is suitable for auto parts, oil drums and so on.The above mainly from the material, performance, cost, safety and use of simple analysis of the PET packaging belt, PP packaging belt and steel belt three packaging tape, respectively. In order to facilitate the vast numbers of users with good choice, different packaging belt, packaging different products. Double glow PET belt has been widely used in the steel industry, aluminum, glass, wood, stone, brick and so on.
Q:Why is plastic strapping broken?
Plastic steel belt itself is elastic, broken tension standard 1608 plastic tape, breaking tension to close to 200kg. There is little possibility that a dozen will break.
Q:Identification of PP packaging belt
Some packaging machines with new materials outside, the middle folder filling material (poor), as long as the cut open to see the section, you can see inside the black heart is poor quality.Packing machine with color problems, packaging machines with different grades, hard to say. The transparent baler belt is the best strapping belt at present. The quality of the packing machine depends entirely on the purity of polypropylene. The higher the purity of polypropylene, the better the tension of the baler.
