An Earphone Blister is typically made of transparent plastic, such as PVC (polyvinyl chloride) or PET (polyethylene terephthalate). This material allows customers to see the earphones inside the packaging while protecting from damage and tampering. The blister is formed into a cavity that securely holds the earphones in place. The earphones are often placed inside the blister cavity, and a transparent plastic film is applied over the blister to seal and protect the earphones. Earphone Blister may include tamper-evident features, such as perforated tear strips or security seals, to indicate if the package has been opened or tampered with before purchase.
