Tengen reimagines document security with packing list envelopes that merge industrial durability and sustainability. Made from 100% recycled materials or biodegradable options, our envelopes minimize environmental impact without sacrificing tear strength (20N/25mm+). Anti-static coatings, pre-perforated edges, and branded printing cater to automotive, retail, and 3PL sectors. Leverage Tengen’s rapid prototyping and global warehousing network to deploy compliant, cost-effective solutions tailored to your supply chain’s unique demands.
Document tampering costs billions. Tengen’s packing list envelopes incorporate holographic foils, blockchain-linked QR codes, and tear-resistant patterns to deter fraud in luxury and pharma sectors. Meet TSA, FDA, and IATA mandates while building end-user trust through unbreachable security.
Standard envelopes fail under harsh conditions. Tengen’s packing list envelopes solve this with Tyvek®-reinforced seams and adhesives rated for -30°C to 120°C. Automotive and pharma clients report 40% fewer document-related delays, ensuring customs compliance and on-time deliveries. For enterprises, Tengen means reliability in every shipment.
Tianzhiyuan offers robust packing list envelopes to protect invoices, shipping documents, and customs forms. With high clarity and strong adhesive, these envelopes stay securely attached throughout transit. B2B clients in logistics, warehousing, and e-commerce rely on our solutions for consistent document visibility and professional packaging.
One-size-fits-all risks compliance breaches. Tengen crafts packing list envelopes in bespoke sizes, coatings, and layouts—from freezer-grade options for perishables to EMI-shielded designs for electronics. Modular production ensures rapid prototyping, empowering agile responses to regulatory shifts.
