Can You Brand Your Window Sample Bags?
What We do for your brand
A branded sample bag isn’t just a carrier, it’s a walking billboard. In the time your bags spend being handled, transported, and presented, they catch the eye of customers, colleagues, and onlookers alike. It’s a subtle but powerful touchpoint for brand visibility and recognition.
At PottertonPacs, we blend your branding with functionality. Whether it’s a logo printed on the exterior for instant recognition or clear usage instructions printed inside, our graphics enhance not just the safety of your window samples but also how your brand is perceived. From vibrant, full colour imagery to thoughtful in-bag messaging, we design for impact and clarity.
