Three-Side Seal Series: A High-Efficiency Protection Solution Under Minimalism
The three-side seal series, with its simplified design philosophy, defines the "gold standard" in the packaging industry. As the most regular and securely sealed bag type, it achieves near-100% sealing redundancy through a three-sided heat-sealing and one-sided open filling logic, making it the optimal carrier for vacuum preservation and long-term barrier. Its flat physical structure not only significantly reduces the marginal costs of transportation and warehousing but also gives products excellent fit, making it the preferred solution for retail single packs, trial packs, and affordable high-quality products. Relying on mature automated adaptation technology, three-side seal packaging performs exceptionally well on high-speed filling production lines. Combined with tear-resistant U-shaped notches and diverse composite film materials, it ensures the freshness and stability of food while achieving a balance between commercial efficiency and packaging aesthetics with minimal packaging material consumption.
