Look closely and it’s easy to see opportunities for backside printing everywhere — not just inside boxes, but under bottle caps, on the inside of snack bags, under the lids of yogurt containers, and more. In many markets, however, less than 1% of all food products are capitalizing on these typically blank areas by using what the industry calls “backside” or “inside” printing. The few that do — including household names like General Mills, Nestlé and others — have demonstrated its ability to boost customer engagement with their brands.
So why isn’t more of this valuable interior packaging space being used?
The simple answer is many food packaging printers don’t know just how easy backside printing can be, or that compliant ink products even exist. With a little coaching, your brand can help them overcome some basic misconceptions — and start taking advantage of one of the fastest-growing ways to build stronger relationships with consumers.
Why use backside printing?
Today’s customers are more involved in the products they buy, and deal with brands more intimately than in the past. They’re more likely to remember your brand — especially if it responds to their engagement — which can massively increase customer loyalty.
Backside printing has the power to take your brand from ordinary packaging to memorable, unique, or even “screaming” packaging. It does this by creating additional branding opportunities that aren’t apparent on the outside. Interior space can be used to boost brand awareness, cross-promote other products, introduce new offerings, or recognize things that are important to the brand or its customers (for example, a tie-in with November for mental health, or October for breast cancer).
Another benefit of backside printing is its ability to stimulate engagement through curiosity. Once your customers know there’s something more in the package, they’ll be encouraged to look inside for other messages the next time they purchase one of your products. It increases engagement with your product.
Inside printing isn’t rocket science
Printers who aren’t experienced with inside packaging techniques often worry that it will make their job significantly more complicated. Common misconceptions include:
- Fears of cross-contamination.
- Lack of knowledge that food safe inks for direct food contact are available, and the thought they must use lamination or overwrapping in some way.
- Belief that special equipment will be required.
Inside Printing Inks
In fact, any experienced press operator can use food-safe inks to add backside printing almost as easily as using conventional printing inks. No special equipment or additional skills are required.
For example, in flexographic, or “flexo” printing jobs, all that is needed are additional units for each of the inside printing inks, plus a turn bar and any corresponding dryer units. Traditional offset presses can get the job done with perfector unit or can run a second pass through the press to apply food contact inks on the back side of the packaging.
Compliant inks also have the advantage of keeping your product sustainable. Since additional lamination isn’t required, paper materials can be deinked after use and recycled into new products.
Many printers are under the mistaken impression that no ink can come into direct contact with food or other products. In fact, there are compliant inks for food and other direct contact applications. That said, backside print applications need to conform to all corresponding regulations set down by FDA or EU standards.
