Our disposable plastic snap locks provide an essential tamper-evident fastening solution for medical healthcare identification, event admission wristbands, and retail fraud prevention. Composed of an independent male stud with a barbed ribbed shank and a precision female locking socket, these disposable plastic snap locks create an irreversible mechanical bond that cannot be pried apart or reused without visible destruction of the plastic components.
Unlike single-piece molded snaps with fixed grip ranges, the SBF-LK-2P03 modular two-part system is manufactured across an extensive range of cap diameters, head shapes (round, square, and oval), and post shank lengths. This multi-size versatility allows factories and brands to secure thin synthetic Tyvek sheets, multi-layer vinyl hospital bands, dense woven polyester ribbons, or thick retail merchandise security tags with equal holding power.
Key Features & Factory Advantages
-
Irreversible Barbed Pin Geometry: Engineered with sharp, conical retaining ribs along the male pin that expand inside the female socket during assembly and lock against internal retaining lips to eliminate non-destructive removal.
-
Multi-Thickness Pin Versatility: Available in multiple shank lengths ranging from 4 mm (ultra-thin paper and Tyvek bands) up to 12 mm (thick cardstock hang tags and multi-ply fabric assemblies).
-
Medical-Grade & Hypoallergenic Safety: Molded from non-toxic, virgin POM and PP resins that are free of phthalates, BPA, and heavy metals. Safe for newborn infant tracking bands and continuous multi-day patient monitoring.
-
E-Commerce Return-Fraud Prevention: Ideal for apparel brands and designer goods requiring tamper-evident anti-wardrobing tags (Please Do Not Remove It security seals) to prevent buyers from wearing and returning garments.
-
100% Waterproof & Laundering Resistant: Immune to degradation from water immersion, hospital sanitizers, saline solution, perspiration, and chlorinated pools.
-
Fast, Tool-Free Manual Insertion: Precision guide points allow clinical nursing staff, venue gate operators, and warehouse packers to press and lock the snaps by hand in less than two seconds.
