Packhelp supplies a complete selection of envelopes designed for business shipping and correspondence. The range provides solutions for sending flat documents that must remain rigid, as well as for protecting small items that require cushioning during transit. All envelopes come in various standard sizes to accommodate items from A5 to A4 and larger, ensuring compatibility with courier and Royal Mail services. They feature secure peel-and-seal adhesive strips for fast and efficient packing, speeding up the fulfilment process. For further operational efficiency, the Adhesive Shipping Label Pouch is a transparent, self-adhesive wallet that securely attaches shipping documents to the outside of any package. With low minimum order quantities, businesses of all sizes can source the postal packaging they need.

Durable cardboard envelopes for documents

For shipping items that must not be bent, such as contracts, certificates, photographs, or art prints, rigid cardboard mailers are the standard. The range includes several types of sturdy postal envelopes to meet different needs. Board-back envelopes combine a flexible paper front with a rigid greyboard backing for protection against creasing. For even greater stiffness and protection on both sides, corrugated mailers are an excellent choice. Products like the Custom Corrugated Envelope use a lightweight but strong E-flute board construction. These mailers also come plain, such as the Plain Cardboard Envelope, or with full-colour custom printing applied to the front surface. Explore the full collection of cardboard envelopes to find the right size and specification for your documents.

Secure padded envelopes for small products

When shipping small, delicate, or irregularly shaped goods like jewellery, cosmetics, books, or electronic components, padded mailers provide essential cushioning. These mailing envelopes feature a durable kraft paper outer, available in white or brown, and an interior lining of air-filled bubbles that absorbs impacts during transit. The Custom Bubble Envelope carries your logo, while the Plain Bubble Envelope is ideal for unbranded shipments. A variety of sizes ensures a snug fit for different products, and the entire range of padded envelopes comes with a strong self-adhesive closure.

Customisation for postal envelopes

You can personalise many envelopes in the range with a full-colour design, allowing businesses to add their logo and branding directly onto their mailers. For items requiring more substantial protection than an envelope can provide, consider a product like the Plain Mailer Box with Custom Sleeve as a sturdy alternative.
