Size: No.20 (350 x 470 mm)
Type: Corrugated cardboard protective mailer
When shipping fragile, valuable, or important documents and products, a standard paper envelope often falls short. The No.20 Padded Corrugated Cardboard Envelope is designed to provide top-tier protection without the need for additional packaging materials like bubble wrap.
This envelope is made from heavy-duty outer cardboard and features an inner single-layer corrugated (wavy) insert. This construction acts as a shock absorber:
Despite being a paper-based product, it is adapted for real-world logistics. The outer surface is coated with a special 5g/m2 PE layer, creating a barrier against moisture, rain, or snow. Your shipment will stay dry even in unfavorable weather conditions.
The packing process is simplified by the integrated peel-and-seal adhesive strip. You won't need extra tape or glue – the envelope seals instantly, ensuring the contents are securely locked inside.
In modern business, sustainability is a priority. This shipping mailer is an excellent alternative to plastic bubble envelopes. The manufacturer states that the envelope is easily recyclable with other paper waste, making it a responsible choice for the environment.
The No.20 Corrugated Cardboard Envelope is an indispensable packaging solution for e-commerce, photographers, or office needs. Its large format makes it ideal for sending large document folders, flat electronic devices, or textile products, providing a professional look and guaranteed security.
Yes, due to its size and durability, it is perfect for all parcel locker networks. Just ensure the contents fit within the specific locker compartment height.
No, the envelope features a very strong adhesive strip that is fully sufficient for secure sealing.
Corrugated cardboard provides significantly more rigidity than standard paper, but it is not a completely rigid box. For items extremely sensitive to bending, we recommend adding an extra sheet of cardboard inside.
