Litter can be packed in pouches, but that’s not the only cat product that comes in standup bags. Cats are generally fed using cat food pouches. They are high quality bags designed to keep the food safe from dust and air.
Coming back to cat litter, the most important feature of its pouch is that it should not let the moisture in, since the litter can become clumpy if it gets wet. This is why zippers are mostly added to these bags. The zipper also helps to reuse the pouch once it is empty.
Unlike a simple plastic pouch, a cat litter pouch is made from laminated layers that do not let sunlight and moisture pass. This prevents the formation of lumps that can be difficult to remove. The broad panels of the pouch provide enough space for the manufacturer to print their logo and product information.
