OPP Bag

OPP bag (Oriented Polypropylene Bag) is a transparent packaging bag made from OPP film. In foreign trade, OPP bags are commonly used for packaging small items such as stationery, accessories, socks, and towels. They are popular for their high transparency, good gloss, dust and moisture resistance, and low cost. Usage scenarios include: as inner packaging in direct contact with the product, or as outer packaging with paper cards or header cards for display. Precautions: OPP bags are not self-adhesive and require tape or self-adhesive strips for sealing; the material is brittle and tears easily, so it is not suitable for heavy or sharp items; for exports to the EU, environmental requirements must be considered—OPP bags are recyclable but not biodegradable, and some countries may impose a plastic tax. Differences from other terms: PE bags (polyethylene bags) are softer and tougher, often used for garment packaging; PP bags (polypropylene bags) are unstretched and have lower transparency; OPP bags are biaxially oriented polypropylene, with high transparency and stiffness, but poor heat-sealing properties, usually requiring coating or special sealing. In foreign trade operations, thickness (e.g., 30 microns), dimensions, printing requirements, and whether self-adhesive are required must be specified.
