Packaging straps and buckles

　　Packaging straps (bundling straps) are mainly made of polyethylene and polypropylene resin as raw materials, and those made of nylon and polyester as raw materials are also available. The straps are made by extruding and uniaxial tension of the raw materials. In addition to sealing packaged corrugated cartons, the straps are also used for bundling bulk parts and securing large packages.
