Ordinary bone bags, also called ‘blow-bone bags’ or ‘compact bags’ have an earlier origin, and the production process is relatively simple. The raw material blown film is directly blown out of a tube with a bone-shaped structure, which can be directly printed and cut. The printing process can only print relatively simple printing content, generally one or two colors are mostly, because there is a bone on the tube material, the roll material is not flat, and it is difficult to achieve multi-color registration. The printing process is usually flexographic, also called letterpress or offset.
To ensure the quality of packaging bags, Dongguan Bone Bag Factory should attach great importance to the aging of bone bags. For this reason, the competent authority of the national building materials industry once required that recycled materials and recycled materials are not allowed in the bag-making raw materials, and the amount of filling materials should be strictly limited to no more than 5%. At the same time, the laminating temperature must be strictly controlled to avoid process problems. Causes accelerated aging problems. Excessive addition of recycled materials is also one of the reasons that promote the aging of the bone bag.
Theoretically speaking, the raw materials of the bone bag after being extruded and drawn to be recycled belong to the scope of recycled materials, but like other products, it is impossible to produce scraps and waste in the production process. Generally speaking, the non-recycled material bone bag means that when the bone bag is produced, there is no external purchase of waste recycled materials, and the flat yarn and waste wire in the production are added to the new material in proportion to reuse, which is "the non-recycled material bone bag" . In order to reduce costs, some bone bag manufacturers use recycled materials (edge wire or waste wire) in excess of the prescribed ratio, and the bone bag will have unqualified strength problems. Attention should be paid to this aspect. In addition, the excessive amount of titanium dioxide is mixed in the ingredients, which increases the dust of the produced bone bag and also affects the strength of the transparent bone bag.
Therefore, the relative breaking force of bone bags containing recycled materials is significantly reduced. If the secondary material is added, the relative breaking force of 0.32N/tex cannot be guaranteed. The elongation at break is unstable, and the breaking rate decreases depending on how much recycled material is added. The brittleness of the recycled material bone bag is obviously increased, especially the low temperature brittleness is worse, the impact resistance is reduced, the electrical insulation is reduced, the aging degree is increased, and the speed is accelerated.
