Why Glue-Free Packaging?
You might be wondering: why would you want to make packaging without glue? Especially for paper products, some adhesives can stick to paper-making equipment which might impact recycling. Some adhesives are suitable for recycling, but designing packaging with its ability to be recycled in mind is important for the packaging design process. Enter: glue-free packaging!
Many corrugated boxes that we offer are glue-free while still offering the structure and protection that the material is known for. For example, our corrugated mailer boxes are a secure packaging option for sending items through the postal system; and they don’t use any adhesives in their construction!
So… How do they do it? While it might seem like magic, it’s much more simple! By using die cut holes and tabs to hold the sides in place, these boxes stay together. The sides with the tabs fold up and over, and sandwich the two short square flaps to form the short sides of the box. This creates a double wall of paper material for stability and also creates a place for the tabs on the lid of the box to slide into!
Our pizza boxes have a similar structure to the mailer boxes. But why don’t we use glue for food packaging? Isn’t it more secure? While food-safe adhesives are available, heat from food could loosen their hold. Enter: the corrugated pizza box!
The main difference between our pizza boxes and the mailer boxes is the die-cut vent holes! These holes help release steam so the corrugated paper material doesn’t become soggy as your pizza is in transit.
Folding Carton Boxes
You can make a number of folding carton styles without using glue! Similar to the way that corrugated boxes fold over to form the walls of the box, folding cartons do the same. Though the concept is the same, some of the construction is a little bit different!
Since the folding carton’s paperboard material isn’t as rigid as the corrugated material is, the small flaps that get tucked in have to be doubled up. How does this work? The flaps come with a perforated line for easy folding, so they can provide more support and structure.
The additional tabs on the shorter ends of the box secure the diagonally folded tabs to create a sturdy folding carton. By using the double-wall method, the paperboard gets more structure, without using any additional materials or adhesives.
While our custom cake boxes are also folding cartons, they are constructed differently! Rather than using the double-wall method, our custom cake boxes use die cut holes to hold everything together.
Cake boxes arrive flat, with a die-cut handle on two sides, and die-cut holes on the others. When folding the box, the handles come together and the holes hold them in place. This creates a secure and convenient way for you to transport your baked goods without using any adhesives.
