Plastic security seals have been proven to be the most affordable and efficient security application for retailers and warehousing solutions. Plastic seals fall into three categories: adjustable length, fixed length or plastic padlock. Plastic seals are often referred to as indicative seals as they “indicate tampering”. These seals are designed to show evidence of tampering and are not a security device, but rather a visual indicator of tampering and thereby can be a theft deterrent. All plastic security seals can be branded, numbered and /or bar coded for extra security.
