The drop resistance of flat bottom pouches (e.g. 8-side seal pouches) is closely linked to both the packaging material strength and the physical properties of the contents. The following two content characteristics most significantly affect drop resistance:

Seal failure occurs when certain factors prevent the areas that should have been joined through heat sealing from properly bonding. The common causes of seal failure are as follows:

Environmental Trend: With increasing awareness and concern for the environment, recyclable packaging has become a crucial means to reduce plastic pollution and promote the recycling of resources.

Bag-in-Box (BIB) is a modern liquid packaging solution that combines a multi-layer inner pouch with an outer cardboard box. It features a sealed spout, inner pouch, and box, and is widely used in beverages, food, and chemicals. Compared to glass bottles or plastic drums, BIB is lighter, more functional, and more eco-friendly.

Retort pouches are flexible packaging designed for high-temperature sterilization (121℃–135℃). They are widely used in food, pet food, condiments, and medical products. The pouch extends shelf life through heat treatment and offers good barrier, puncture resistance, and sealing properties.

During the manufacturing process of retort pouches, several common issues may arise. To effectively resolve these challenges, we will conduct a detailed analysis from multiple dimensions. This approach will ensure that the final retort pouches meet higher quality standards and performance requirements.

Optimizing the process cost of laminated packaging is closely linked to ink application volume during printing. Precise control of ink volume ensures high-quality printing on flat-bottom pouches and enhances printing speed. Controlling the ink volume is key to scientifically and reasonably reducing the cost of flat-bottom pouches. The basic principles of ink application are as follows:
