Manual strapping and machine strapping are not the same! First of all, in the raw materials, the raw material of the machine packing belt is mainly PP or the packing tape of PET resin polyester single machine has high requirements for hardness and verticality, and the raw materials of the hand strap It is a packing belt made by mixing some recycled materials on the basis of PP raw materials, but the brightening of the packaging belt which is not used in the color is indeed cheaper than the packaging belt for the machine. However, when the hand strap is used on the baler, there is no machine strap for use, and the cassette phenomenon is more likely to occur. At present, the use of strapping on the market is more and more extensive, so there will be a lot of manufacturers spending not only time and energy on the strapping, in order to provide customers with high-quality strapping, and constantly introduce advanced foreign technology, Improve the quality of the strap and other places.
Steel strapping
It is generally used to make a very heavy load into a whole transport piece or to fix the load in a train car, trailer or ocean freighter. It is rarely used for shrinking loads that are sunken or displaced after bundling, but the strong bundling has been compressed. The load is often used for the bundling of rigid loads.
2. Nylon strapping
It has a high sustained tension and is generally used for the binding of heavy-duty articles and shrink-type loads that can withstand high initial tension. Its elongation and recovery rate are larger than polyester or polypropylene strapping, and it is the most expensive plastic. Packing tape.
3. Polypropylene strapping
It is the cheapest strapping material and is generally used for bundling, bundling and sealing cartons for lighter loads. Polypropylene straps have high elongation and recovery, but are not as strong as other plastic straps.
4. Polyester strapping
It has the highest strength and highest sustained tension in plastic strapping. Polyester strapping is an excellent tying material for rigid loads that require a constant tension during loading, unloading, transport and storage. It is often used in applications requiring high tensile strength, high sustained tension and elongation. In many cases, it behaves like a lightweight steel strap.
5.PP packing tape
This product is used in conjunction with the automatic baler machine. It is suitable for the packing and packaging operations of newspapers, publishing houses, bookstores, paper mills, department stores, food, post offices, confectionery shops, timber shops, etc.
