Hũ thủy tinh kín 2L

Ưu điểm cốt lõi của sản phẩm

1. ​​Double sealing technology​
   It uses a combination of spring clips and food-grade silicone rings (thickness 3.5mm), which has been verified by negative pressure testing (-80kPa) to maintain the freshness of food for more than 12 months. The 140mm wide mouth design is suitable for quick storage and access of granular foods such as coffee beans and nuts, and the opening and closing life is up to 5,000 times.
2. ​​Vật liệu thủy tinh soda-vôi​
   It complies with GB 4806.5-2016 food contact material standards, and the lead migration amount is less than 0.005mg/L. The tank body is 4mm thick, the impact strength is 1.2MPa, and the transportation damage rate is controlled within 0.8% (based on the 2024 quality inspection report of the Zibo factory).
3. ​​Storage efficiency optimization​
   The cylindrical structure (diameter 140mm×height 230mm) is suitable for standard storage shelves, supports four-layer stacking, and the single pallet loading capacity reaches 432 pieces, which increases the warehouse space utilization rate by 18%.

Nắp đậy kín khí hoạt động như thế nào?

Cơ chế kẹp nắp được thiết kế để tạo ra một lớp niêm phong chặt chẽ, ngăn không cho không khí vào hoặc ra. Điều này đảm bảo thực phẩm tươi lâu hơn và tránh bị ô nhiễm. Không giống như nắp vặn, nắp kẹp đáng tin cậy hơn trong việc duy trì bảo quản kín khí.
