The Void seal is a product protection system in the form of an adhesive seal label. When the void sticker is violated, the word VOID will appear written both on the sealed surface and on the seal itself in most models. Normally used directly on the products to protect them from undue openings during the warranty period. When placing it in the package instead of the product, another seal is used in this case: destructible seal. The lacre void label is sold with the following options: plain without printing or personalized with printing at the customer's discretion.
