Key Features
1.Complete and Aesthetically Pleasing Front Design: The seal of the back-seal bag is hidden on the back, with no obstructions on the front, maximizing the integrity of the front design. The design allows for a unified front image, maintaining continuity, resulting in a refined, aesthetically pleasing, and distinctive appearance.
2.Significant Cost Advantage: For packaging bags of the same size, the back-seal method minimizes the total seal length and reduces material consumption. Without affecting production speed, it can reduce packaging material usage by approximately 40%, resulting in a significant cost advantage.
3.High Production Efficiency: The back-seal bag manufacturing process is mature and suitable for high-volume, rapid production. Automated packaging equipment can switch between back-seal and three-side-seal bags through modular design, meeting the packaging needs of all channels.
4.Strength and Protection: The bags have stronger pressure resistance on both sides, greatly reducing the possibility of packaging damage. They also offer advantages such as moisture and water resistance, insect and pest protection, and prevention of product spillage.
5. Excellent display effect: The back-sealed bag has a full shape after packaging, which is especially suitable for inflatable packaging (such as nitrogen-filled potato chips), with outstanding visual effect and strong shelf appeal.
