Advantages of Square Bottom Pouch
Less Film
Square bottom pouches work as well as other types of packaging that stand up on their own. These pouches use less film, but they hold a lot more. Packaging that uses less material is always beneficial for a business because it requires fewer resources and money, meaning you get more bang for your buck. Compared to other packaging options, the square bottom pouch uses 12 percent less film and takes less energy to make. Their lightweight feel is another plus for distribution. It takes up less space when it comes time for transportation.
More Stability
The less film and a lighter feel might give the impression that this choice of packaging is not stable, but that’s not true. square bottom pouches offer more stability for the products inside. These boxes consist of three layers that keep the products firmly inside. The additional layers don’t add extra weight, either. The flat bottom ensures they stand up on their own, making it easier to store and stock the boxes on shelves inside stores.
Better Creativity
If you need a packaging option that gives you more options for promoting your brand, look no further. Square bottom pouch pouches have five graphic panels for you to use to increase your branding. The side gussets offer more room for printing. Use the extra space to put pictures of the product, the company logo, and special characteristics that the competition doesn’t offer. Customize them to display the appropriate image or message to your customers.
Guaranteed Freshness
After customers buy your products and go home, do you know how long the freshness of that product lasts? If it’s in the standard bag that doesn’t reseal after opening, then probably not very long. Square bottom pouch pouches come with a resealable zip lock, helping you maintain product freshness. Consumers probably won’t use the entire product in one sitting. Keeping freshness is important so they can enjoy the product for a couple more days. Plus, the sealing is strong, so you don’t need to worry about anything seeping through. This is especially essential for food items.
