ColomPac shipping packaging White DIN B5 self-adhesive closure CP 037.52

ColomPac shipping packaging White DIN B5 self-adhesive closure CP 037.52 is a white mailer sized to fit B5 documents and small items. The mailer features a peel-and-seal self-adhesive flap that creates a secure, tamper-evident closure for postal and courier handling. Constructed from lightweight but durable material, the packaging protects contents from bending and light moisture while keeping packing fast and consistent for regular dispatch operations.

Advantages

The self-adhesive closure enables quick sealing without additional tape or glue, reducing packing time and material waste. The B5 format matches common document and small-item dimensions, providing a snug fit that limits movement inside the mailer. The plain white surface offers a neutral appearance suitable for business correspondence and can accept labels and stamps cleanly. The mailer's construction balances light weight for reduced shipping cost with sufficient rigidity to protect thin or flat items.

Suitable for

• Dispatch of B5 letters, brochures, and catalogs
• Sending small flat products such as passports, thin booklets, or printed media
• E-commerce shipments of compact items that require lightweight protection
• Mailing documents that need a tamper-evident seal for postal services

Key specifications

• Format: DIN B5 size suitable for B5 documents and items
• Color: white surface compatible with labels and stamps
• Closure type: peel-and-seal self-adhesive flap for tamper-evident sealing
• Material: lightweight, tear-resistant packaging material for basic protection
• Protective properties: resists bending and light moisture during transit

How to use

Insert the document or item flat into the mailer so it sits evenly without excessive folding. Remove the protective strip from the adhesive flap, fold the flap down and press firmly along the edge to form a secure seal. For additional security or when sending heavier contents, reinforce the closure with clear tape along the flap edge. Addressing can be done directly on the surface with a label or stamp; ensure the writing area is clean and dry before application.

Usage recommendations

Store the mailers in a dry environment away from direct sunlight to maintain adhesive performance. Choose the B5 mailer when contents match the flat dimensions to avoid unnecessary movement; consider adding a stiffening insert if shipping fragile thin items. Comply with postal service guidelines for dimension and weight limits to ensure proper processing.
