- Measurement Method
- The size of the self-sealing bag is measured as W*L (full length of the bag), where L = total length, L1 = mouth length, and L2 = usable length. The mouth length varies depending on the size of the bag, Approx. as follows: 1.5 × 2.5 cm to 5 × 7 cm, L1 = 0.5 cm; 6 × 8 cm to 10 × 15 cm, L1 = 0.5-1 cm; 11 × 16 cm to 17 × 25 cm, L1 = 1-1.5 cm; 18 × 26 cm to 28 × 40 cm, L1 = 1.5-2.5 cm.
- Product Application
- Suitable for snacks, dried fruits (moisture and odor-proof), valuable jewelry (moisture and oxidation-proof), batteries, ethanol, medical supplies, metal products (to prevent mutual interference affecting medical effects and rust affecting usage), grains, and miscellaneous grains (to prevent odor mixing and maintain high transparency).
- Material
- Food-grade PE self-sealing bag made of thick, durable, and environmentally friendly material. Thickness measurement may have a ±0.01 mm error, which is within the normal range.
