The technical performance of strapping material

Banding is to use flexible strapping material ( Or other accessories) Packing will be more than or packing of goods tied together, a collection of cargo, the effect of retaining the goods and packaging container. Can prevent the goods movement, collision, overturned, or collapse crib, still can have anti-theft, decorative role. Goods after strapping, strapping tape will be regulated by the effect of tensile force, and by the circulation of temperature and humidity and other environmental factors by the influence of the home, in order to ensure the effectiveness of the cargo hold firm. You should understand the physical and mechanical properties of the strapping material, in order to properly apply correctly. ( 1) Strength banding material tensile deformation resistance is used to represent the tensile strength and tensile strength. ( 2) Elongation elongation elongation at break, refers to the total length of strapping material after stretching the difference with the original long and length ratio, measured as a percentage. Elongation characterization of the size of the plastic deformation, the smaller the elongation. Is tied with the material of package is not easy to loose respect. ( 3) Stretch recovery it refers to the amount of tension after removing, strapping tape back extension of rice, unit cm ( cm) 。 It represents the strapping material elastic resilience of PE bottle. ( 4) Tensile stress and tensile stress attenuation after strapping material by the tensile stress is called the tensile stress produced within it. If the material under the action of tension, keep a certain time, the stress will decay, the stress is called the tensile stress decay.
