Yambao Solutions develops patented linerless self seal technology for corrugated boxes and mailers. It is a tape free packaging solution built for modern e commerce and fulfillment operations. The cohesive self seal system bonds only to itself when pressure is applied, while remaining non tacky during storage and handling. This eliminates plastic tape and silicone release liners, reduces packaging waste, improves pack out speed, and simplifies automation ready corrugated sealing. The result is a cleaner, more efficient, and more sustainable approach to shipping packaging.
