Overview

The 4-seal bag is the preferred packaging format for cat litter and pet care products. Its four-side sealed structure provides complete protection against moisture, dust, and odor—critical for maintaining the performance of clumping litter.

With a top-mounted handle, it allows easy carrying and stacking on shelves or in homes. The stand-up design keeps the bag upright when filled, improving visibility and accessibility.

Perfect for pet stores, supermarkets, and e-commerce platforms, this bag combines durability, functionality, and cost-efficiency.
