Application: Polypropylene filler yarn is used as a 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.

Q:What's the difference between PP strapping and PET packaging?: PET packing belt, PP packing belt and steel belt. The following packages are used to analyze the differences between the three packaging belts.

Q:What is the reason that the packing belt of the packer is not glued?: Packaging materials with the belt has a bearing, you may have this batch of packaging materials, raw materials doped more ingredients, and now on the market with the main component of polypropylene, commonly known as PP. A better pack should have a PP content of more than 95%. Other ingredients are complex, such as mixing calcium carbonate, talc, wollastonite, glass fiber and other inorganic fillers. If the ingredients are more, the hot-melt viscosity is poor. It is recommended that you provide the supplier with the matching parameters.

Q:What is the reason that the packing machine can not be put in?: Tighten wheel belt did not stir, blocking the slip past

Q: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.: 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 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:Packing belt 120616061608.: You see the tensile strength index, according to your box size, weight, you decide.

Q:What band is the most popular packing belt?: This is generally not business insiders do not know.I am doing logistics, packaging tape with a lot of consumption. As for other industries

Q:The baggage for my American traveler's cloth is to be checked. Do you need a doggy belt? Will it protect the box?: Someone will steal the main transferThey also have a lot of people, leaving a gap above the handle, so it is also convenient. It's still used, but not much

Q:What material is the packing belt made of?: The arrangement of methyl groups on the same side of the molecular backbone is called isotactic polypropylene. If the methyl group is arranged in random order on both sides of the backbone, it is called atactic polypropylene, and when the methyl group is arranged alternately on both sides of the backbone, syndiotactic polypropylene is called. In general industrial polypropylene resins, the isotactic structure is about 95% and the remainder is atactic or syndiotactic polypropylene. Industrial products are based on isotactic substances. Polypropylene also includes copolymers of propylene with a small amount of ethylene. Usually translucent, colorless solid, odorless, non-toxic. The melting point can be as high as 167 DEG C because of the highly crystalline structure. Heat resistance and corrosion resistance, products can be steam disinfection is its outstanding advantages. Small density, is the lightest general plastic. The disadvantages are low temperature resistance, low impact and easy aging, but can be overcome by modification.

Q:Why is plastic strapping broken?: A serious imbalance in the proportion lead to too brittle packing belt. Or stored for a long time, long sunny rain. It might get crispy. Originally, the quality of plastic belt maintenance time is very long, it is a substitute for steel belt in horizontal wet packaging environment. It should be low cost and strong breaking force.
