Bubble Envelopes - K/7 - 350mm x 470mm

The K/7 bubble envelope is designed to provide practical protection for medium-sized items during transit. With internal dimensions of 350mm x 470mm, it is ideal for posting items such as brochures, textiles, documents, or boxed products that require a lightweight yet durable mailing option.

Sturdy Kraft Paper Outer Layer

Constructed from 90gsm uncoated white kraft paper, the envelope offers strong resistance against punctures and tearing. The smooth exterior is ideal for clear labelling and barcode readability, making it suitable for e-commerce, postal services, and business dispatches.

Cushioned Interior for Damage Protection

Inside, the envelope is lined with bubble film that cushions contents against bumps, compression, or handling during shipping. The internal surface is smooth for hassle-free loading and protects delicate items such as electronics or small parts from friction damage.

Peel-and-Seal Adhesive Closure

Each envelope includes a self-adhesive sealing strip, allowing for fast and reliable closure without the need for additional tape. Once sealed, it forms a tamper-evident finish that keeps items secure until delivery.

Practical and Efficient

Supplied in packs of 50, these envelopes are an efficient packaging option for businesses handling frequent shipments. Their balance of low weight and protective quality helps reduce postage costs while maintaining product safety.
