Cardboard Envelopes

Cardboard envelopes provide robust protection for items that must remain flat and uncreased during shipping. Their rigid construction prevents bending and damage, making them a reliable choice for sending important documents, photographs, art prints, and certificates. All variants feature a simple peel-and-seal adhesive strip for quick and secure closure, streamlining the packing process. The range includes multiple sizes designed to fit standard paper dimensions and accommodate various flat products.

Types of cardboard envelopes

The collection includes two primary constructions: solid board and corrugated cardboard. Solid board mailers, like the Plain Cardboard Envelope, offer a stiff, slim profile ideal for letters and thin documents. For items requiring more substantial protection from impact, corrugated options provide an extra layer of cushioning. These mailers use fluted cardboard, which absorbs shocks and resists crushing. Unlike flexible padded envelopes that cushion against bumps, rigid envelopes focus entirely on preventing bending. This makes them the designated solution for shipping items where flatness is the top priority. Both types come in a variety of standard sizes to suit different courier and postal service requirements, ensuring a secure fit for contents.

Corrugated envelopes and board back envelopes

For enhanced structural integrity, both corrugated envelopes and board back envelopes deliver superior stiffness. Board back envelopes feature a strong greyboard backing with a paper front, excellent for items that need support but also a surface for clear labelling. Fully corrugated envelopes, such as the Plain Corrugated Envelope, enclose the product completely in protective fluted board.

Personalising rigid cardboard envelopes

Beyond plain stock, Packhelp provides options to personalise rigid envelopes with custom branding. You can print a full-colour design directly onto the surface of the mailer, turning a functional shipping item into a marketing tool. You can add this to products like the Custom Cardboard Envelope and also for the durable Custom Corrugated Envelope, allowing for consistent branding across different packaging types. The printing process accommodates detailed logos, text, and graphics. Businesses can order custom-printed cardboard envelopes in quantities that suit their needs, with low minimums available for all types.
