Tamper-Evident Packaging: Induction Seals, Security Seals and Heat Seals for Small Producers
Quick answer: Tamper-evident packaging shows the buyer if a pack has been opened. Small producers usually use induction seal liners under bottle caps (applied with an induction sealer), tamper-evident security seals over caps and lids, or heat-sealed pouches that must be torn to open. Security seals start from KSh 15,000 and induction sealing machines from KSh 260,000.
