Widely applicable: two sizes to meet different needs

Rugged: Protect your goods
The black and white courier bag made of high-strength polyethylene film has excellent physical properties, is not easy to break and is resistant to abrasion. In the process of handling, even if there is a sharp object piercing or heavy pressure, it is still intact. At the same time, this material also has a moisture-proof and waterproof function, which can preserve the internal materials for a long time in a humid environment without damage. This makes it an indispensable and important tool in long-distance transportation.
Each black or white surface is smooth and flat, which not only increases the beauty, but also makes it easier to write content such as marking address information. And because of its moderate thickness, it will not appear too thin when filling items, giving people a sense of security. This design fully takes into account the actual needs of users, so that every consignment becomes more assured.

Environmental protection concept: green packaging helps sustainable development
With the increasing awareness of environmental protection, more and more enterprises begin to pay attention to the selection of green products. Our black-and-white express bags are made of degradable materials, which can be quickly decomposed into harmless substances in nature and return to Mother Earth after completing their mission. In addition, the entire production process follows strict energy-saving and emission-reduction standards, reducing carbon emissions and other pollutant releases, and truly achieving a win-win situation for economic and ecological benefits.
The company has been adhering to the business philosophy of "innovation leads the future", actively exploring the development and application of new materials, and actively promoting the circular economy model. I hope that through my own efforts, more colleagues will participate in this great change and work together to create a better tomorrow!
