Problems solved by technology

Generally, there are disadvantages of low tensile strength, easy deformation and short service life.
When the packing box is packed with this kind of packing belt, the packing box will be deformed due to external force, which will make the packing belt loose due to its own expansion and contraction, and the goods will be damaged by loose packages, which will bring a lot of trouble to the transportation and handling of goods. question

Embodiment 1

[0025] The compound comprises 99%-100% by weight of polypropylene, 0-10% by weight of antioxidant and 0-10% by weight of anti-ultraviolet agent. Of course, the mixture may also include polyethylene in an amount of 0-20% by weight. Specifically, it includes 99% by weight of polypropylene, 5% by weight of antioxidant and 5% by weight of anti-ultraviolet agent. Of course, the fiber filaments can also be twisted.

Embodiment 2

[0027] In the composite strapping belt of the present invention, the compound comprises 40% to 98% by weight of polypropylene, 0 to 20% by weight of polyethylene, and 1 to 40% by weight of polyolefin elastomer , 0-10‰ antioxidant and 0-10‰ anti-ultraviolet agent. Specifically, it includes 69% by weight of polypropylene, 10% by weight of polyethylene, 20% by weight of polyolefin elastomer, 5% by weight of antioxidant and 5% by weight of antioxidant. 5‰ anti-ultraviolet agent. Of course, the fiber filaments can also be twisted.

[0028] Such as figure 1 Shown, the production technology of composite packing belt of the present invention may further comprise the steps:

[0029] 1). Add the mixture to the extruder 1 to melt, and at the same time pass the fiber filament 2 through the mold 3;

[0030] 2). Extrude the melted mixture in the extruder 1 and the fiber filament 2 through the mold 3 to form a composite packing belt 4;

[0031] 3). The composite packing belt 4 is cooled...

Abstract

The invention relates to a compound packing strap, comprising fiber yarns and a mixed material covering the fiber yarns, wherein the mixed material contains polypropylene accounting for 99% to 100% by weight percent, antioxidant accounting for 0 to 10per mill by weight percent and anti-ultraviolet agent accounting for 0 to 10per mill by weight percent. The compound packing strap has the characteristics of high strength, non-deformability and long service life, is strong after packing, and prevents goods from being damaged by pack collapse since a packing box is deformed and becomes loose under the external force, thereby solving the problems the usage of the current packing straps brings to goods transportation and carrying.

Description

technical field [0001] The invention relates to a composite packing belt and a production process. [0002] Background technique [0003] At present, the packing tape widely used in product packaging is plastic packing tape (including polypropylene and polyethylene packing tape). After many years of use, this kind of packing tape obviously has many shortcomings. Generally, there are disadvantages of low tensile strength, easy deformation, and short service life. When the packing box is packed with this packing belt, the packing box will be deformed due to external force, making the packing belt loose due to its own expansion and contraction, and the goods will be damaged by loose packages, which will bring great difficulties to the transportation and handling of goods. question. [0004] Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a composite packing belt with high strength, no deformation, firm packing a...
