Plug cases – folding folders with tuck closure for product protection and packaging

Plug cases are a type of folding carton packaging that does not require gluing.

They are a simple, practical, and cost-effective solution, consisting of four flaps (two shorter and two longer ones) that allow quick assembly.

Closing is easy – first the shorter flaps are folded, then the slotted flap is closed by inserting the locking tab, creating a compact and sturdy folder.

Plug cases are ideal for packaging documents (catalogs, presentations, flyers), promotional materials, samples, and thin products.

The packaging offers a large printable surface, allowing fully customized branding. It can be printed on one or both sides.

Printing is done using advanced HP Indigo digital technology, ensuring high-quality and precise results even in small runs.

A range of 20 different sizes is available, covering a wide variety of applications.

High-quality carton materials ensure stability and product protection.

For added durability, you can choose coating or lamination, while 3D UV spot coating can be used to highlight key elements and create a tactile effect.

Plug cases are ideal for B2B presentations, document shipping, promotional kits, and material organization, where both protection and a professional appearance are important.

For a more flexible packaging solution, see also flat bags.

Remember – packaging is often the first interaction between your product and the customer. A well-designed solution strengthens brand recognition.

Choose your size, customize your design, and order plug cases that protect and professionally present your product.
