Korrvu® Electronics Packaging uses a strong, highly resilient film to surround your products to protect them from shock and vibration. Use Retention Packaging Kits for products that need a limisted degree of protection. The design of this Electronics Packaging suspends your product in the airspace of the shipping container between two layers of resilient, low-slip film. Korrvu® Electronics Packaging ships knocked down. Additional inserts are sold separately.
