Polyolefin Flat Bags

Polyolefin Flat Bags are plain-open polyolefin pouches engineered to combine the toughness of PE with the stiffness of PP, so the film stretches without tearing yet still holds a flat, wrinkle-free form on the roll or stack. Heat-seal strength is specified at 15 N per 15 mm, giving a reliable closure that opens cleanly without film tear at the seam. Bags run from 5x8 cm to 60x80 cm at gauges of 0.05-0.2 mm and are decorated by offset printing, which delivers sharp, uniform graphics across a flat bag surface. Material meets food-contact GB 4806.7 and GB/T 21665-2009, and an optional 80 percent recycled PO blend is available. The product is a general-purpose flat packaging pouch where clarity, stiffness and a strong heat seal matter more than structural features like zippers or gussets, and where the bag must feed predictably on high-volume packaging equipment.

For a flat polyolefin bag, buyers run into two consistency problems: film that is either too soft to feed straight or too brittle to heat-seal cleanly. Our standardization balances PE toughness and PP stiffness in the same film formulation so every bag in a run feeds flat, lies wrinkle-free, and reaches the same 15 N/15 mm heat-seal strength. Because blown film and offset printing are integrated, the flat, dimensionally stable surface that offset printing needs is produced in-line, which keeps registration tight on large orders rather than drifting as softer film warps on the press. For a brand or packer buying flat pouches by the million, the value is a standardized polyolefin bag that runs predictably on filling and packaging equipment, seals reliably at 15 N/15 mm, and carries offset graphics that stay identical from the first pallet to the last.

Sizing from 5x8 to 60x80 cm, gauge 0.05-0.2 mm, PE/PP toughness balance, offset printed artwork, optional 80% recycled PO blend, and production from customer drawings or samples are offered. OEM and mixed specs within one MOQ are supported.

Bags are packed in export carton boxes. Trade terms are negotiable; transit-damaged items are replaced, and third-party inspection is accepted.
