Tamper evident bags have become a common security measure in many food and beverage products to prevent contamination and spillage and maintain the integrity of the finished product. Tamper-resistant seals, rings and pouches ensure the quality and freshness of the product, and provide manufacturers with a degree of security. The complete tampering technology in the tamper evident bag conveys the safety and reliability of the finished product, but production errors may occur during the final sealing stage of the primary packaging, affecting the safety seal. http://www.fqpackaging.com/products/tamper-evident-bags/
