As a family business with over 75 years of experience in the cartonboard trade, we at Engelkarton not only know the materials, but also the needs of our customers. Thanks to our established network in the industry, we are able to develop special solutions that go far beyond the standard range - by bringing together partners with the right expertise.

One particularly exciting project was our collaboration with Ultimate Guard, a leading provider of high-quality accessories for storing and protecting trading cards and comics. The challenge: a special cardboard box for so-called comic backing boards. These are inserted behind individual comic books to give them stability and protect them from creases, waves or other damage - a particularly important requirement for valuable graded comics that are professionally evaluated and often decades old.

Conventional cardboard materials quickly reach their limits here. Many contain acidic components or chemical residues that can damage the sensitive surface of the comic covers or even the booklet itself in the long term. Ultimate Guard was therefore looking for a partner who was able to develop an acid-free, age-resistant and chemically neutral cardboard - robust enough for everyday use and yet completely suitable for archiving.

Together with two specialized partners from our network - a manufacturer of acid-free cardboard raw materials and an expert in protective surface coatings - we were able to deliver the perfect solution after intensive development work: a high-quality special cardboard that is precisely tailored to the needs of Ultimate Guard and its customers.

Today, these comic backing boards are a real bestseller - and are already helping tens of thousands of collectors worldwide to protect their favorite pieces.

For us at Engelkarton, this is a great example of how much is possible when you network expertise - and work passionately on individual solutions.

We look forward to your inquiry!
