SGL Packaging offers premium quad seal coffee bags designed to keep your coffee fresh, safe, and stylish. These bags have four sealed corners and two strong side gussets, helping them stand upright and hold their shape when filled. Perfect for coffee beans, ground coffee, tea, and other dry goods, they combine high-quality protection with custom branding to make your products stand out.
The Quad or Four Corner Seal bags are pillow-shaped and do not have a central closure at the back. They have two side gussets, providing greater reinforcement to help the bag maintain its shape when filled and on display.
These bags have several layers that allow sealing, blocking of light and contaminants, and custom printing.
They also come with DEGASSING VALVES and PEEL-AND-STICK TIN TIES that conveniently allow you to reclose the side gusseted bags.
At SGL Packaging, we have created an easy, fast, and safe way to receive your signature coffee packaging without having to leave your home or coffee shop. You just need to select the product within the packaging category, choose the specifications, send your design file to us, make the payment, and within a few days, your customized coffee bags will be delivered to your door.
