How to identify the quality of packing tape

Release date:2015-06-27 00:00 Source: Views:

Strap quality is good or bad, depending on purity polypropylene packing tape Gaobu Gao, now packaged with a variety of sub-markets: pure polypropylene, add masterbatch, polypropylene plus renewable materials, PP renewable materials plus and masterbatch. Packing pure polypropylene production with full transparent state, plus packaging polypropylene masterbatch production for translucent polypropylene plus production of renewable materials packaged with substantially opaque, polypropylene plus masterbatch production and packaged with recycled materials completely opaque. There is also a full-renewable materials and calcium carbonate powder packaged with sandwich material production, complete production of renewable materials packaged with relatively soft material of the tape sandwich is only the surface of the raw material, the rest are calcium carbonate (lime powder). Strap quality is good or bad depends entirely on the purity of polypropylene, the higher purity polypropylene packing tape tension better.

  Packing belt fitting manner:

  a) melt lap. After it uses electric welding, heat welding method of high frequency oscillation mechanical and ultrasonic welding or the like, it is heated to melt the plastic surface with the melted surfaces of the two ends of the lap belt up at a certain pressure to maintain a certain time, to be melted surface condensation adhesive plastic strip joints good way. The joint approach applies to polypropylene plastic tape, because polypropylene plastic with metal buckle belt when fastened mechanically, its strength is only 50% of the base material, adhesive connection does not apply.

  b) metal button. This method is to use a one-way ratchet tensioner work to make the belt tension, then placed an iron buckle at the joints, and then clamp the iron buckle wrap two straps and sides of teeth irregularities iron buckle tooth, bite the tape will not to release it. Iron buckle usually made of galvanized iron, to adapt to choose the specifications of the iron buckle strap model based on the operation.

  c) Ligation. Such joint approach is based on flexible plastic rope, twine as the tying materials, joints labeled slipknot. This joint approach both strong and beautiful, and easy to untie.


Strapping PP and PET is made by mixing two plastics.

The main production processes: plastic pellets melt pressure zone --- ---- ----- wrapped roll forming ---- cooling ---- Packaging - storage system using polypropylene packing tape by heating, melting, pull stretch, cooled to produce packaging material mesh structure, influence strap quality of basic parameters is tension, length, bending, elongation. At the same tension and other parameters, the lower the cost of longer length.

Several commonly packaged with:

a) steel strapping. Generally used to make a very heavy load integral transport member or the load securing inside the train, trailer or ocean-going vessel, rarely used after tying subsidence or displacement of contractile load, but can be firmly tying already compressed loads and loads are often bundled for rigidity.

b) nylon strapping. With high sustained tension, generally used for heavy objects and can withstand high initial contractile tension load strapping, elongation and recovery rate with a larger than polyester or polypropylene packaging, is the most expensive plastic packing tape.

c) polypropylene strapping. Cheapest tying material, which is generally used for lighter loads tying, bundling and sealing cartons. PP strapping has a high elongation and recovery rate, but not as good as others continued tension plastic packing tape.

d) polyester strapping. It has the highest strength and maximum sustained tension in the plastic packing tape. For the requirements in the handling, transport and storage process has been maintained rigid load strapping tension, polyester strapping is an excellent tying material. Is commonly used for high tensile strength, high tensile and elongation of occasions continued, in many occasions, its performance is similar to the specifications of the light steel strapping.
