With the rapid development of the e-commerce logistics industry, the demand for packaging materials is increasing. Grey plastic postage bags have become an important packaging tool for cross-border e-commerce, domestic express delivery, and warehousing logistics due to their strong light-shielding properties, waterproof and tear-proof properties, firm sealing, and affordable prices. As a professional plastic packaging bag production factory, we have long provided customers with high-quality mailing bags, factory direct supply, support for multi-specification customization, quality assurance, and stable delivery.
Grey plastic postage bags are made of LDPE or recycled PE co-extruded film material, with a smooth surface, flexible feel, standard gray or dark gray color, and good light-shielding and privacy protection functions. The bag mouth comes with a high-strength self-adhesive seal, which cannot be opened again once sealed, and has good anti-theft and anti-tampering properties.
