Paper Sos Bags

Over 20 Years of Packaging Experience

We are located in Longgang, Wenzhou. Our factory covers 5,000 square meters with 60 skilled employees. We operate 6 Heidelberg printing presses and 12 finishing machines. Since 2000, we have specialized in packaging production and provide both OEM and ODM services.

Each Paper SOS Bag undergoes strict quality inspection. Our team checks the bottom and side strength, tests the self-opening function by shaking, and carefully reviews printing quality to ensure consistent performance.

Shake It, and It Opens Automatically

SOS stands for "Self-Opening Sack." When the bag is shaken, it opens automatically, saving time during packing and improving efficiency for your staff.

The square bottom design allows the bag to stand upright, making it convenient for both storage and use. It is widely used in takeaway food packaging, such as fried chicken, fries, bread, and burgers.

Made from recycled materials, this bag is 100% recyclable and environmentally friendly, helping your business reduce waste while maintaining practicality and efficiency.

Simple Samples and Fast Customization

We provide free existing samples (shipping cost covered by customer). Custom samples can be produced within about one week, and the sample fee is refundable upon bulk order confirmation.

During production, we provide photo and video updates. Each bag is carefully inspected, flattened, and packed into strong corrugated cartons for safe shipping. After your order, we maintain close communication and offer dedicated pre-sales consultation and after-sales support. We stand behind every product we make.
