Adhesive Envelopes

What Are Adhesive Envelopes?

Adhesive envelopes — also known as document enclosed envelopes, packing list pouches, shipping label pouches, or packing slip envelopes — are self-stick plastic pockets that attach directly to the outside of a carton or parcel to carry the invoice, packing slip, delivery docket, customs paperwork, or any other shipping documents that need to travel with the goods.

The peel-and-stick adhesive backing means no extra tape, glue, staples, or labels needed — peel off the backing paper, press the envelope onto the carton, slide your documents inside, and the parcel is dispatch-ready. The clear front (or clear pocket window) lets the recipient and couriers see the documents through the envelope without opening it.

QIS stocks 2 sizes/styles, both in bulk cartons of 1,000:

• Clear plain pouches — fully transparent, no printing
• 'Invoice Enclosed' pouches — white with bold pre-printed "Invoice Enclosed" text, perfect for visibility

Stock items, same-day dispatch on orders before 12pm.

Why Choose QIS Adhesive Envelopes?

The strong adhesive is the genuine selling point — these envelopes hold securely through the rough handling, vibration, and weather exposure of typical freight transit. No documents falling off mid-journey, no missing paperwork at the delivery end, no claims-and-disputes about whether the invoice was sent.

Both sizes fit a standard A4 sheet folded into thirds (the typical invoice/packing list format) — no need to redesign your paperwork or use smaller-than-standard documents. The 1,000-piece bulk cartons match the typical dispatch volume of small-to-medium e-commerce, manufacturing, or distribution operations, with strong per-piece economy compared to small packs. Backed by QIS's 5% price-beat guarantee.

'Invoice Enclosed' Printed vs Clear — Which Should You Use?

Both serve the same job (attaching documents to a parcel) but with different visual styles:

• 'Invoice Enclosed' pouches (white printed) — make the documents inside immediately recognisable to couriers, receivers, and customs officers at a glance. Reduces the chance of the documents being missed or ignored, and increases the perception of professional dispatch. Best for invoices, packing slips, customs paperwork on international shipments, and any document that the recipient absolutely needs to find.
• Clear plain pouches — fully transparent so the document inside is visible through the envelope without needing any pre-printed labelling. More flexible — you can use them for any document type (not just invoices), and the document itself communicates what it is. Best for varied documents, branded packing slips, and when you don't want the standardised "Invoice Enclosed" look.

Many businesses stock both — the printed version for invoices and the clear version for everything else.

How to Use Adhesive Envelopes

The process takes about 5 seconds per parcel:

1. Peel the backing paper off the adhesive side
2. Press the envelope firmly onto a flat surface of the carton (top is most common — visible to handlers and recipient)
3. Slide the document(s) into the envelope through the opening
4. Done — the documents travel securely with the parcel

For high-value or sensitive documents, fold the document so any private information faces inward. The transparent front means anything facing outward is visible to anyone handling the parcel.

What Documents Go in Adhesive Envelopes?

The standard contents include:

• Invoices — the most common use, especially for B2B shipments
• Packing lists / packing slips — itemised contents lists for the recipient
• Delivery dockets — proof-of-delivery paperwork
• Customs paperwork — declarations, commercial invoices, certificates of origin for international shipments
• Return instructions — pre-printed return shipping labels and forms
• Care/handling instructions — for fragile or temperature-sensitive items
• Marketing inserts — thank-you notes, discount cards, promotional flyers (though many businesses prefer to include these inside the carton with the product)
