In order to ensure the quality of the packaging bags, we should pay attention to the aging of the adhesive bags. For this reason, the national building materials industry department requires that the bag-making raw materials should not contain recycled materials and recycled materials, the amount of filler should be strictly controlled within 5%, and the lamination temperature should be strictly controlled to avoid accelerated aging due to process problems . Excessive addition of recycled materials is also one of the reasons for the aging of the bone bag.

Theoretically speaking, the raw materials of the bone bag can be recycled after being squeezed and stretched, but like other products, it is impossible to be without waste and leftovers in the production process. Generally speaking, non-recycled bone-attached bags refer to the production of bone-attached bags without the use of outsourced waste recyclables. The flat yarns and waste filaments in the production are added to new materials in proportion to reuse, that is, "no recycling Material of the bone bag". In order to reduce costs, some bone-fitting bag manufacturers use recycled materials (edge ​​wire or waste wire) exceeding the prescribed proportion. The strength of the bone-fitting bag will be unqualified. This aspect should be paid attention to. In addition, an excessive amount of titanium dioxide is added during the batching process, which increases the dust of the sticky bone bag and affects the strength of the sticky bone bag.

Therefore, the relative tensile force of the bone adhesive bag containing recycled materials is significantly reduced. If secondary recycled materials are added, it is difficult to guarantee the index of 0.32N/tex. The elongation at break is unstable, and the breaking rate decreases according to the amount of recycled material added. The brittleness of recycled materials with bone bags has increased significantly, especially the low-temperature brittleness is poor, the impact resistance is reduced, the electrical insulation is reduced, the aging degree is increased, and the speed is accelerated.
