## Long description

The NC Koperty B4 cardboard expansion envelope is a robust mailing solution designed to provide secure transport for documents, catalogs, and various flat items. With a generous 5 cm gusset, this brown envelope offers significant extra capacity, allowing it to accommodate bulkier contents that standard flat envelopes cannot handle. Constructed from high-quality, durable cardboard, it provides reliable protection against bending and minor impacts, ensuring that your materials arrive at their destination in excellent condition.
Advantages
The primary benefit of this expansion envelope is its structural integrity combined with its flexible capacity. The reinforced cardboard material offers a professional appearance while maintaining high resistance to tearing and wear during the shipping process. The gusseted design allows the envelope to expand to fit thicker stacks of paper or small items, making it a versatile choice for businesses that require a dependable mailing option for diverse contents. Its standardized B4 size ensures compatibility with common shipping requirements and document formats.
Suitable for
Shipping thick catalogs and brochures
Mailing multi-page documents and reports
Transporting flat office supplies and stationery
Sending small, non-fragile commercial items
When it may not be suitable
This envelope is not intended for shipping highly fragile or delicate items that require shock absorption or cushioning, as it lacks internal padding. It is also not suitable for items that exceed the 25x36 cm dimensions or require protection against moisture, as the cardboard is not waterproof.
Key specifications
Dimensions: 25 cm x 36 cm
Gusset width: 5 cm
Material: Durable cardboard
Color: Brown
Quantity: 100 envelopes per pack
How to use
To use the envelope, simply insert your documents or items into the main compartment. Ensure the contents are centered to allow the gusset to expand evenly. Once the items are placed inside, fold the flap over and secure it firmly using the integrated adhesive strip or your preferred shipping tape. Ensure the surface is clean and dry before applying any shipping labels to guarantee proper adhesion.
What to consider before purchase
Verify that your items fit within the 25x36 cm footprint
Assess if the 5 cm expansion is sufficient for your specific document thickness
Consider the weight of your contents to ensure the cardboard provides adequate support
Usage recommendations
For optimal results, avoid overstuffing the envelope beyond its 5 cm capacity, as this may strain the seams. When shipping important documents, consider adding a rigid insert if extra protection against bending is required.
