【Partner Company Bag Case】Successfully solved the customer's problem with 【Seal Reinforcement】! - Addressed the weaknesses of lamination processing by strengthening the sides with seal reinforcement -

The lamination process involves bonding OPP film and CPP film together. Typically, OPP film, which has good ink adhesion and high moisture resistance, is used on the outside, while CPP film, known for its excellent heat sealability and abrasion resistance, is used on the inside.
This time, our customer requested OPCP laminated bags. However, we heard that when they previously had bags made, the seal strength was weak, and the sides of the bag's opening were very prone to tearing.
The reason for this is that during the lamination process, slight differences in the tension applied by the machine when bonding the films and the adhesion of the adhesive can lead to variations in how well the films stick together. This can result in the edges opening up when the film is placed on the bag-making machine, causing issues with proper sealing on the sides.
To address this problem, we utilized a "reinforcement seal." When applying the reinforcement seal, we made sure to:
- Be cautious about the temperature being too high to avoid deforming the bag.
- Minimize any residual marks from the reinforcement on the bag.
To ensure these two points were considered, we consistently managed the temperature during the process. The issue was successfully resolved, and the customer was satisfied!
