Custom Three Side Seal Bags

China LIJIE Factory Wholesale

Three-side seal bags, also known as flat bags, typically feature three sealed sides with one open side. Regular three-side seal bags do not stand on their own, but adding a bottom insert transforms them into stand-up bags. LIJIE in China offers wholesale custom services for three-side seal bags, and we welcome your inquiries.

Three-side seal (stand-up) bags are among the most commonly used soft packaging types. They provide excellent freshness preservation and sealing, offer high cost-performance, and are easy to produce, making them an ideal choice for brands and retailers.

Target Markets

These bags are suitable for a wide range of industries, including daily necessities, food, and medical fields. Common products include face masks, plasters, snacks, eye masks, surgical masks, tea bags, cosmetics, storage bags, and more.

How to Customize Three-Side Seal Bags

There are many parameters for custom packaging bags, such as bag type, size, material, quantity, and thickness. All these parameters are essential. If only one or two parameters are provided for an inquiry, we cannot offer a comprehensive quote. For fast orders, customers should provide all of these details to our customer service.
