Proven by data, based on quality——as a professional manufacturer of vacuum tin boxes, we use solid data to interpret the excellent quality and production strength of vacuum tin boxes, breaking the perception that "quality cannot be quantified". From raw materials and craftsmanship to finished products, every core indicator is supported by accurate data, making the quality of each vacuum tin box traceable and verifiable. We empower product competitiveness with data and become a trustworthy partner for vacuum tin box manufacturing.

　　Raw material selection is strictly controlled by data. High-quality food-grade tin materials are selected. After authoritative testing, the heavy metal residue is ≤0.001mg/kg, which is far lower than the national standard for metal materials for food contact (≤0.01mg/kg). It is odorless and free of harmful coatings, with full safety factor; the thickness of the tin material is accurately controlled at 0.23-0.28mm, which not only ensures the toughness of the box body, but also takes into account light weight. The compressive strength can reach 1200N, which can withstand 50kg stacking pressure without deformation, and the wear resistance times are ≥10000 times, still as clean as new after long-term use.

　　The data of vacuum technology highlights strength. Adopting automatic vacuum packaging technology, the vacuum degree is accurately controlled at -0.092~-0.098MPa, and the packaging error is ≤0.1mm, ensuring that the tin box is completely sealed, with an air leakage rate of ≤0.01%. It can effectively isolate air, moisture and dust, extending the shelf life of internal items by 3-5 times——tea can be kept fresh for more than 18 months, nuts and dried goods can be moisture-proof and insect-proof for 6 months, and candies can maintain their taste for 9 months. Production strength is also supported by data. It has 12 automatic production lines, with a daily output of 8000-10000 pieces. The delivery cycle of customized orders is ≤7 days, and the sampling qualification rate is ≥99.8%. Each batch of products undergoes 32 indicators of full inspection, guarding the quality of each product with accurate data, and meeting the bulk purchase and customization needs of customers with core strength.
