Buried metal construction provides double protection against static discharge. Amine/amide-free interior will not corrode polycarbonate surfaces and produces no outgassing. The semi-transparent material allows for easy identification of contents. Because these bags are fully heat sealable the contents are effectively protected from moisture and foreign matter. The 3/8 MIL-Spec seal ensures packaging integrity during storage and handling. Elkay's focus on defect prevention versus defect detection builds quality into every bag.
