Flat poly bags are a versatile choice for parts, hardware, literature, and kit packaging. Choose clear plastic bags when product visibility matters, or opaque styles when light protection or discretion is needed. Provide your target dimensions, thickness, and packing method; our team will confirm fit, recommend alternatives, and help you balance durability with cost.
Match bag width/length to product plus a small margin for a clean seal.
Pick bag styles that suit your sealing method and workflow.
Consider how cases will stack and dispense at the line.
For parcel shipments, poly mailers provide lightweight, tear‑resistant protection and help lower DIM weight. Self‑seal mailers can speed up packing without extra tape, while returnable and gusseted styles support exchanges or bulkier items. Tell us the items you ship most often, and we’ll suggest mailer sizes that minimize waste and reduce packing time.
Clarity and thickness influence presentation and protection. If appearance is important, specify high‑clarity film for a clean, professional look. For heavier or sharp‑edged contents, step up thickness to resist punctures. Not sure what you need? Share your use case and any failure points you’ve seen; we’ll recommend a practical spec and send samples for verification.
Whether you need a few cases or consistent replenishment, Seal‑tec can scale with your demand. We support poly bags wholesale orders, standing purchase plans, and usage‑based replenishment through Vendor‑Managed Inventory (VMI). Ask about blanket PO options and stock‑and‑release for predictable costs and ready availability.
