About Our Products

How do I know what box size is perfect for my product?

1. Measure the product (length, width, height) with enough space for padding or protection.

2. Search our catalog for the box with suitable internal dimensions.

3. If you need advice, our Sales team can guide you.

Can I make a box with the exact measurements I need?

Yes. We carry plain corrugated boxes in most categories (white, regular, and tabbed). For custom sizes, please contact us to review minimum availability and production times.

Do you have eco-friendly products?

Yes, we're constantly adding more sustainable options. Visit our Eco-Friendly Packaging Collection to see environmentally friendly boxes and materials.

What is the difference between bubble envelopes and rigid envelopes?

• Bubble Mailers: These have an inner layer of bubble wrap that protects fragile and lightweight items. Ideal for electronics or small fragile items.

• Rigid Envelopes: Made with cardboard or a hard material that prevents bending. Perfect for documents or items that don't need to be folded.

What is the difference between regular kraft boxes and white boxes in terms of strength?

White and regular kraft boxes have the same strength if they share the same gauge (single corrugated). The choice is usually more about aesthetics or presentation. White boxes tend to give a cleaner or more premium appearance, while kraft boxes offer a natural, rustic look.
