As a family run 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 can 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 cartonboard 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 damages - a particularly important requirement for valuable graded comics that are professionally valued and often decades old.

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

Together with two specialized partners from our network - a manufacturer of acid-free cartonboard 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 cartonboard 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 items.

For us at ENGELKARTON, this is a great example of how much is possible when you combine expertise - and work passionately on customized solutions.

We look forward to your inquiry!
