Why we do not publish a price or a fixed MOQ here. This is priced by material and by run length rather than per piece, and both move with the resin index. A minimum order is set by the economics of a single production run, not by a policy. We state it against your actual specification rather than as a number that rots.

What it is

Two separate webs sealed on all four edges. Unlike the three-side-seal there is no fold, so front and back can be entirely different materials or artworks (e.g. printed foil face + clear back). Fully hermetic and dimensionally stable; used where seal integrity matters more than shelf presence.

Variants

• Vacuum four-side-seal
• Foil face / clear back sample pouch
• With peel-open seal (剥离封)
• With chevron seal for aseptic presentation
• Double-web with different laminate each side

Typically used for

Sterile medical device and syringe packs · Vacuum-packed sliced meats and cheese · Pharmaceutical and diagnostic reagent packs · Premium sample and trial sachets · Electronic component packs
