Blockout Masking Labels

CILS International’s blockout (cover-up) labels are essential for when confidentiality or correction is key.

Designed to obscure information beneath them, they are pivotal in labs and pharmaceutical environments where patient data, ingredient lists, or outdated information must remain hidden.

They are used for the purpose of blind or double-blind studies and can also provide a quick fix for pre-labeled products with typos or inaccuracies. Featuring a high-opacity adhesive, these labels act as a steadfast veil over unwanted text or images, ensuring the information remains blocked even under scrutiny.
