Security Seals for Parcels Avery Zweckform 78 x 38 mm, 100 labels, red-white

Avery Zweckform security seals for parcels, 78 x 38 mm, pack of 100 labels in red and white provide a simple visual tamper-evidence solution for shipments and envelopes. The adhesive labels are designed to adhere securely to packaging surfaces and show clear signs of attempted opening, helping couriers, retailers and logistics teams identify compromised parcels at a glance.

Advantages

These parcel security seals combine a compact size with high-contrast red-and-white marking to increase visibility on boxes and envelopes. The self-adhesive backing ensures reliable attachment to paper, cardboard and many coated surfaces, while the construction is intended to reveal tampering through adhesive disruption or visible residue when removed. Supplied in a pack of 100, they are suitable for regular use in shipping workflows and returns handling without requiring tools or special dispensers.

Suitable for

• Courier and postal parcels requiring tamper evidence
• Retail returns and exchange shipments
• Internal logistics and stock transfers
• Sealing envelopes with sensitive documents

Key specifications

• Label size: 78 x 38 mm
• Pack quantity: 100 labels
• Colour: red and white
• Adhesive type: peel-and-stick tamper-evident adhesive
• Material: pressure-sensitive label material designed to show tampering

How to use

Clean and dry the surface where the seal will be applied. Peel a single label from the backing and press it firmly onto the package or envelope, smoothing from the centre outward to ensure full contact. Apply seals over package seams, closures or envelope flaps so that any attempt to open the item disturbs the label. If removal is attempted, the label is designed to leave visible evidence of tampering, such as adhesive residue or surface disruption, alerting handlers to possible compromise.

Usage recommendations

For best performance, store labels in a cool, dry place and use within the manufacturer’s recommended storage period. Test adhesion on a small area if applying to non-standard or highly textured surfaces. Use seals together with shipping documentation and tracking procedures to maintain clear chain-of-custody records.
