E-commerce & Logistics

Yun Sealoong provides custom e-commerce and logistics packaging for brands, retailers, and fulfillment-focused buyers. This collection includes poly mailers, bubble mailers, kraft paper mailers, courier bags, shipping boxes, and protective cushioning, designed to keep products safe, present your brand, and control shipping costs.
Our mailing bags use durable LDPE and co-extruded films with padded bubble or kraft structures, plus options for waterproof, tear-resistant, and tamper-evident double adhesive strips, and opaque security finishes. Corrugated mailer boxes and insulated cold-chain liners are available for heavier or temperature-sensitive shipments.
Everything is customizable: your logo and full-color printing, custom sizes from small apparel mailers to large bulky-item bags, colored and metallic films, and eco options including recycled-content and compostable mailers. We support OEM/ODM projects from small brand runs to high-volume wholesale supply.
Backed by our own factory established in 2012, we control printing, lamination, and bag-making in-house under IQC, IPQC, and FQC inspections. The factory is ISO certified, food-contact materials are FDA-compliant, products hold CE certification, and material performance is verified through SGS testing.
MOQ is flexible depending on size, material, and print. Share your product type, weight, and shipping channel, and we will recommend a mailer structure and provide a quotation. Browse the products below or contact us to start.
