It can accurately adapt to the sizes of various gifts, avoiding loose storage, jamming and poor fitting problems.

　　In the structural forming quality inspection, key inspections are carried out on die-cutting accuracy, indentation technology and bonding assembly quality. The die-cut edges must be flat and smooth without burrs, damage or missing corners. The indentation lines are uniform in depth and accurate in position, without cracking, line bursting or offset indentation, ensuring smooth folding, regular edges and corners and square forming of the gift box. Full coverage inspection is implemented for bonding parts to eliminate glue opening, excess glue, virtual adhesion and wrinkles, with tight and flat fitting and no loose debonding under force. Special reinforcement quality inspection is carried out on the connection structure between the handle and the box body to check the uniformity of stitching spacing and the fitting degree of reinforced patches, eliminating virtual stitching, missing stitching and patch falling off. It ensures uniform stress on the handle, completely solving the common defects of handle falling off and loose structure of ordinary portable gift boxes, making the box structure stable and durable for long-term repeated use and long-distance transportation stacking scenarios.

　　Targeting the core attributes of portable gift boxes such as portable load-bearing, damage resistance and long-term durability, the portable carry handle gift packing box builds a full-scenario simulated performance quality inspection system to verify the practical quality of gift boxes through professional mechanical tests and environmental simulation tests, ensuring finished products adapt to diverse scenarios including daily carrying, logistics transportation, long-term display and temperature difference changes. Firstly, the load-bearing fatigue test is carried out. According to the rated load weight of the gift box, static load standing test and dynamic repeated lifting test are conducted. Under the rated load state, the gift box has no collapse, deformation, handle looseness or falling off after standing for 24 hours. After hundreds of repeated opening, closing, lifting and placing tests, the box structure and handle parts have no damage or deformation, far exceeding the conventional industrial quality inspection standards.

　　Secondly, anti-damage and weather resistance performance tests include compression resistance, folding resistance, wear resistance, moisture resistance and temperature resistance tests. The compression test simulates logistics stacking and extrusion scenarios, and the gift box has no depression, crease or cracking after stacking and bearing pressure. The wear resistance test detects the wear resistance of the box film and printing layer through friction test, with no paint peeling, scratching or discoloration. In the moisture resistance test, the gift box is placed in a constant temperature and humidity damp environment for a long time without softening, deformation, mildew or glue opening, adapting to damp warehousing environments. Meanwhile, the high and low temperature resistance test verifies the stability of the gift box under temperature difference changes, avoiding brittle cracking at low temperature and soft deformation at high temperature, fully ensuring stable quality of the gift box in different regions, seasons and circulation scenarios, and thoroughly solving the shortcomings of ordinary gift boxes such as easy damage, poor moisture resistance and poor temperature adaptability.

　　The high-end texture of gift packaging relies on refined appearance and printing quality inspection standards. Tiny printing and appearance defects will directly reduce gift grade.
