Plain zipper bag

Standard zip-lock bags are typically larger in size and made from woven fabric, transparent PE, or OPP plastic film. They feature a standard plastic zipper and are commonly used to package bulky items, such as outer packaging for quilts or large, lightweight luggage bags.

Document zipper bag

File zip-lock bags are also known as slider zip-lock bags.
The file zip‑lock bag can hold numerous documents, pens, and small items. It’s made from a unique cold‑resistant double‑layer PVC material that offers excellent flexibility. Waterproof and moisture‑proof, it’s ideal for studying, everyday use, and travel.

Hidden zipper bag

Invisible zipper bags, also known as bone‑tight zipper bags, are typically composite flexible packaging made from materials such as polypropylene (OPP), polyester (PET), nylon, matte film, aluminum foil, cast polypropylene, polyethylene, kraft paper, or even woven fabric—usually in 2 to 4 layers.

Invisible zipper bags are widely used in industrial packaging, daily chemical packaging, food packaging, pharmaceuticals, hygiene products, electronics, aerospace, technology, and the defense industry, among other fields.

Invisible-zipper pouches are typically aluminum‑plastic composite bags, a packaging solution that combines the advantages of various packaging types. They offer low cost and high‑quality printing. These pouches feature anti‑static properties, UV protection, moisture resistance, oxygen barrier performance, light shielding, as well as excellent cold‑ and oil‑resistance, high‑temperature tolerance, and strong sealing capabilities.
