How to choose plastic steel strapping?

Plastic steel strapping is a kind of polyester packing tape which is mainly used for extrusion and single-phase drawing. It is the most popular new environmentally friendly packaging material for replacing steel strip and steel wire. Since 2002, domestic demand for PET strapping has grown five times in the past, for all walks of life. With the strength of the country, the company has developed well and promoted the development of this industry. Due to the widespread use of plastic steel strapping, there are many users who choose to buy, and the plastic strapping is superior to other strapping.

Good steel strapping

Plastic steel strapping is an important product. The main reason why it is used in large quantities is that it has the following five characteristics:

(1) It has strong tensile strength, and it has the tensile strength like steel belt and the ductility which can resist impact, and it can ensure the safety of transportation of products.

(2) The elongation is small, and the elongation is only one-sixth of that of the polypropylene tape, and the tension can be maintained for a long time.

(3) The temperature resistance is strong, the melting point is 260 degrees, and the use is not deformed below 120 degrees.

(4) The safety is good, and there is no steel belt rust to pollute the bundled object, and the color is bright.

(5) Good economic benefits. The length of 1 ton PET strapping is equivalent to the length of 6 tons of steel strip of the same specification. The unit price per meter is 40% lower than that of steel strip, which can reduce the packaging cost.

Good steel strapping

Many users have some quality problems when purchasing plastic strapping, which leads to quality problems for the products that are bought. How to choose a good steel strapping when purchasing plastic strapping, mainly includes the following six aspects:

(1) Tensile strength test: the same specification of plastic steel PET strapping, the higher the purity, the stronger the tensile strength;

(2) Color observation: Today's plastic steel strapping has been produced into a variety of colors. It is of course difficult to identify the color by visual inspection. We mainly observe the purity of the color. The more transparent the color, the higher the purity of the added raw materials. The quality of such plastic steel strapping is better;

(3) Gloss contrast: Gloss is better than no gloss, and gloss is presented by the material itself;

(4) Combustion experiment: Ignite with a lighter, blow it off after 3 seconds, draw with iron objects, observe whether the formation of the wire is uniform, uniform is good. After several times of pulling, the wires are overlapped and pulled apart again to see if it has elasticity. Can it be pulled again and continuously, and it is good to break after breaking or opening a distance. At the same time, it can also smell its smoke, compare its taste difference with ordinary packaging belt after burning. If these two methods are not confirmed, the state of the packaged belt after burning can be observed. If the black smoke or the melt quickly drops during the burning process, it is not a good packing belt.

(5) Section of the incision: the section is rough and not shiny, indicating that the material quality is poor, and it is not a good plastic steel strap;

(6) Straightness test: The better the quality of the PET plastic strip, the better the straightness, but some workmanship, the belt will be twisted and the width is not uniform.

Therefore, everyone should choose carefully when choosing plastic steel strapping . According to the above introduction, choose high-quality packing belt. If you choose a bad quality packing belt, it may cause unnecessary loss to your later packaging.
