OPP cellophane bag

An OPP bag (often called a cello or cellophane bag) is a bag made from oriented polypropylene film. Stretching the film during production makes it thin, stiff and exceptionally clear, so the packed product is shown with almost no haze.

Typical uses

OPP bags are popular for individually packed garments, socks and baby items, jewellery and accessories on hang displays, greeting cards and stationery, gift items, and as inner protection for e-commerce goods. Most are made from BOPP film, usually in the 25–50 micron range.

OPP vs PE bags

• Clarity: OPP is glossy and glass-clear; PE tends to look slightly milky.
• Feel: OPP is crisp, holds its shape and crinkles audibly; PE is soft, quiet and conforms to the product.
• Toughness: PE stretches and tolerates sharp or heavy items better; OPP does not stretch and tears easily once nicked.

OPP bags come plain, with a resealable adhesive strip, with a permanent shipping seal, or with a hang hole. Not every OPP bag is suitable for food; if you pack food, ask for a declaration of compliance covering the film and any print or adhesive.
