SealSafe™ Tamper Evident Paper Bags

A paper delivery bag with the tamper evident closure built into the bag, so packing is one action instead of two.

Most tamper evident delivery packaging is assembled on the bench: a standard bag, then a label, a strip of tape or a staple to close it. That works when it is done consistently, and it is rarely done consistently at volume — seals land in different places, get missed on busy shifts, or are applied where a bag can still be opened elsewhere.

SealSafe™ puts a peel-and-seal tamper evident closure into the bag itself. Staff pack the order, fold the flap and press it down. If the bag is opened after that, the closure shows it at handover. It does not stop anyone opening a bag — it makes an opened bag obvious to the person receiving it.

What the bag has to reveal

Sealed, or opened since packing

The person taking the handover has a few seconds and no knowledge of what happened upstream. The only useful question a bag can answer in that moment is whether it has been opened since it was packed. SealSafe™ is built to answer that question and nothing more.

Built in. The tamper evident closure runs across the mouth of the bag as part of the bag, with the release liner still in place. Nothing separate is fetched, aligned or applied at the bench.

Sealed. The liner is peeled and the flap pressed down at pack-out. One action, in the same place on every order, by whoever is packing.

What it does not do: it is not a lock, and it does not prevent access. It does not track the bag, identify who opened it, or authenticate the goods inside. It gives you a defensible point in the journey — sealed at pack-out, checked at handover — and evidence when something happened in between.

Why an integrated bag

One bag instead of a bag plus a seal

Bag plus separate seal

Two components and a decision at every pack. Sealing quality varies between staff and between shifts, extra materials sit on the bench, and a label applied to the wrong part of the bag can be worked around without touching it.

SealSafe™

The closure is part of the bag, in the place the bag actually opens. There is one action to train, nothing to run out of separately, and the same seal position on every order that leaves the site.

Paper construction

The commercial case

What an integrated packing format changes

SealSafe™ is bought as packaging, not as a security consumable. The difference shows up in three places: what sits on the bench, how long a pack-out takes, and whether the evidence is actually there when someone looks for it.

01

Fewer components

One line to order, store, count and replenish instead of a bag plus a separate seal, tape roll or stapler. Nothing runs out independently mid-shift, and there is no second item to specify, price or keep in stock at every site.

02

Faster pack-out

Fold and press. There is no reaching for a seal, peeling a liner off a small label or squaring it up on the bag, which is where time and inconsistency go when volume is high and staff turnover is normal.

03

Evidence that is where it should be

Because the closure is part of the bag, the seal is always across the opening rather than wherever it happened to be applied. The check at the far end becomes one glance at one place on every order.

04

No separate release liner

A separately applied security label leaves a silicone release liner behind at every pack. An integrated closure does not create that waste stream at the sealing step, so there is one fewer thing to peel, hold and put somewhere.

No separate label. No loose release liner.

Because the tamper evident closure is part of the bag, the packing process does not produce the loose silicone liner that comes with a separately applied security label. At volume that means fewer components to handle, less liner waste collecting around the packing area, and a simpler process to train and repeat — with the closure always in the same position at the bag opening.

This is a housekeeping and workflow point, not a safety claim. We are not going to tell you it prevents accidents; we will tell you it removes a component and a waste stream from the sealing step.

Where it does not help

If your packing is low volume, or the bag has to be a specific existing format you already buy, applying a separate paper label or tape to that bag will do the same job for less change. The integrated format earns its place at volume, across multiple sites, or where sealing consistency is the thing going wrong.

We would rather tell you that than sell you a bag. Send us the pack and the workflow and we will say which is the sensible route.

How it is made

Built with Euro Packaging

SealSafe™ is a joint development: Euro Packaging manufactures the paper bag, TamperTech supplies the tamper evident closure technology. That combination is the point — a bag made by a bag manufacturer, with a seal designed by people who do nothing else, rather than a security feature retrofitted to whatever bag was already in stock.

Euro Packaging publish their own account of the product: SealSafe at Euro Packaging.

Practically, it means the bag can be specified as packaging first — size, paper weight, handle format, print — with the security closure treated as part of the construction rather than a consumable bolted on afterwards.

Where it is used

Handovers that leave your control

SealSafe™ is designed for the point where an order passes to a driver, a collection shelf or a customer — where nobody in the chain can vouch for what happened between packing and arrival.

01

Food delivery and takeaway

Kitchen to packing bench to driver to door. A sealed bag lets the customer see the order has not been opened on the way. Related: fast food security.

02

Grocery and rapid delivery

Multi-item orders with chilled and high-value lines, picked by one team and delivered by another. Related: food and beverage.

03

Pharmacy and prescription bags

Dispensed items held for collection or delivered to a patient, where a disturbed bag needs to be spotted before it is handed over. Related: healthcare.

04

Click and collect

Orders sitting on a collection rack in a public-facing area, sometimes for days. Related: in-store collection.

05

Hospitality and events

Packed meals, amenity packs and guest items moved by venue staff and contractors across a site.

06

Meal kits and recipe boxes

Prepared components packed centrally and handled by carriers. Related: recipe kit security.

Application and integration

Fitting it into pack-out and handover

Packing

Pack the order, fold the flap over, press along the closure. There is no separate seal to fetch, align or run out of, which is what keeps sealing consistent when the site is busy.

The check at the other end

The seal is only worth having if someone looks at it. Give drivers, collection staff or the customer one instruction: if the closure is disturbed or the void message is showing, do not accept it as delivered — log it. Without that step you have evidence nobody reads.

Print, branding and numbering

Bags can carry your own print, and the seal area can carry wording that tells the recipient what to check. Where you need order-level traceability instead of a visual check, sequential numbers and barcodes are normally handled on a custom label applied alongside the bag; tell us which you need and we will say which route fits.

Sizes and volumes

Bag dimensions, paper weight, handle format and quantities are specified per operation. Send the pack you use today and the daily volume rather than asking for a code from a list — the size and the way it is filled drive the specification.

Recyclability

The bag and closure are paper-based, for operations reducing plastic in delivery packaging. Local collection rules vary, so we describe the construction rather than making a disposal claim on your behalf.
