Embodiment Construction

[0022] The technical process of the present invention is described in detail below again:

[0023] 1. The process of dehumidifying and drying polyester raw materials (including chips, bottle flakes and bottle flake reclaimed materials):

[0024] Molecular sieve dehumidification is adopted, and the hot air system is used for drying. The method is: filling drying. The entire drying system is a sealed system, and the dried polyester raw materials (including slices, bottle flakes and bottle flake reclaimed materials) cannot be in contact with external humid air. The water content of polyester raw materials (including chips, bottle flakes and regenerated bottle flakes) entering the extruder is controlled at less than 0.02%, the temperature of the hot air is 160-180°C, and the drying time is 6 hours. When the water content in polyester raw materials (including chips, bottle flakes and bottle flake reclaimed materials) is high, the polymer will be severely degraded under the action ...

Abstract

The invention relates to the technology field of a packing strap, in particular to a polyester strap and the processing technic. The invention solves the problems of easy deformation, poor intensity and short service life of the common plastic packing strap including the polypropylene and polyethylene packing straps. The packing strap utilizes the PET thermoplastic polyester as the raw materials, which is made through fused blending molding by an extruder, through at least twice stretching and tempering process and then through shaping. The packing strap has width of 9.5mm to 32mm, thickness of 0.55mm to 1.3mm and tensile strength of 400MPa to 550MPa. The processing procedure includes dehumidification drying the polyester raw materials such as slice, bottle flakes and reworked materials of the bottle flakes; extruding thick slice; stretching and heating the thick slice at least twice; embossing; tempering thermoforming; cooling forming and rolling, and the processing procedure above can be finished by arranged devices on each parts capable of realizing the processing procedure in turns.

Description

technical field [0001] The invention relates to the technical field of packing tape, in particular to a polyester packing tape and a processing technology thereof. Background technique [0002] At present, the packing tape widely used in product packaging is plastic packing tape (including polypropylene and polyethylene packing tape). After years of use, this kind of packing tape obviously has many disadvantages: easy deformation, poor strength, and long service life. short. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new packing belt to overcome the defects of easy deformation, poor strength and short service life of existing plastic packing belts (including polypropylene and polyethylene packing belts). [0004] The technical solution adopted by the present invention to solve the technical problem is: a polyester packing belt, using PET thermoplastic polyester as a raw material, melted and mixed by an ex...
