Material options

With a gorgeous matte finish, our classic white custom cardboard boxes are our most popular option. It takes well to any color especially bright, vibrant hues.

Brown inside and out, our natural kraft cardboard is as eye-catching as it is rugged. It works well with deep colors, giving an unmistakable warm and muted finish to your design.

When you're ready to get fancy, Dreamcoat is the obvious choice. It's our premium material with a satin finish. You'll notice a glossy surface on printed, high-saturated areas that creates a striking contrast with unprinted areas.

    Super easy to use website and I love that I was able to create my own sizing. The design was exactly how I wanted it; and even though there were no instructions, it was very easy to assemble my boxes when they came. They even came a week earlier than planned! I hope all my future experiences with this company will be as good as this first one.

    Packlane has been great to work with. Small minimum order size provides a great value to those looking to iterate their packaging design or pitch to investors and buyers prior to doing a large packaging run. Staff was also easy to work with and ensured that my packaging came out great. Graphics were also easy to upload and see a demo of the packaging in real time.

    Truly I don't do customer reviews often if ever (I should but I don't) but WOW. Blown away with the amazing service I just received from Packlane on their website chat with Mills. Cannot appreciate this enough and I know all small business owners understand when I say you CANNOT beat a company like this that takes the time to help out every question along the way. Incredible. 15/10- cannot recommend enough!!!!! thank you packlane!
