DESCRIPTION
The 18 x 30 cm Silver Bubble Mailers – #1 provide durable and stylish protection for your shipments. Made from metallized polyester film, they offer excellent resistance to moisture, tearing, and wear, while maintaining a professional metallic finish. With a 5 mm bubble lining, these envelopes effectively cushion contents against shocks and impacts during transit. A permanent self-adhesive flap ensures a secure, tamper-proof seal, keeping items safe from pickup to delivery. Ideal for shipping delicate products, electronics, jewelry, or important documents, these mailers combine strength, protection, and a premium look.

HOW TO USE

Select the appropriate mailer size, leaving enough space for secure sealing.
Place the item inside, ensuring it is centered and cushioned by the bubble lining.
Peel off the adhesive strip and press the flap down firmly to seal.
Clearly label the envelope with the recipient’s details before handing it to your courier.

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.
