tear strip boxes

tear strip boxes are mailing boxes fitted with a built in perforated strip that the customer pulls to open the parcel along a neat line, with no knife, scissors or torn cardboard. The same style can carry a second adhesive strip so the box can be resealed and used for a return, which makes it a favourite for clothing, footwear and subscription brands. Custom Postal Boxes makes tear strip boxes to order in the UK, with custom sizes, free design support and free UK delivery.

How tear strip boxes work in practice

The strip is a narrow band of material set into the board during manufacture, running across the panel that needs to open. A small tab is left accessible at one edge. When the customer pulls the tab, the board separates along a controlled perforated line and the lid is released in one movement. Because the opening is guided, the box stays intact rather than being ripped apart, and nothing sharp goes anywhere near the products inside.

Why easy opening matters more than it sounds

Opening a parcel is the first physical interaction a customer has with an online order. Struggling with tape, cutting into a box or damaging the packaging to get inside colours everything that follows, and a blade slipped through tape can mark the product itself. A clean single pull feels considered, keeps the contents and the box undamaged, and leaves the customer with packaging that is still presentable if the item needs to go back.

Tamper evidence as a useful side effect

A box sealed with an adhesive strip and opened by a tear strip shows clearly if it has already been opened, because the perforated line cannot be restored once pulled. That visible evidence reassures customers that their order has arrived untouched, and it helps your team spot interference quickly when a parcel is returned.

Returns, sealing and tear strip boxes for repeat orders

The most valuable version of this style carries two adhesive strips as well as the tear strip. The first adhesive strip seals the box when you pack it. The customer opens the parcel with the tear strip, and if they need to return something they fold the lid back down and seal it with the second adhesive strip, which has been protected by a removable cover until that moment. The box makes the full round trip without the customer hunting for tape.

Board, sizing and postage considerations

Tear strip boxes are usually made from single wall corrugated board, with the perforation depth set for the specific board so the strip pulls cleanly without weakening the panel in transit. Sizing still matters for postage, and the Royal Mail size and weight guide gives a Small Parcel limit of 45cm by 35cm by 16cm and 2kg for typical ecommerce orders. Our tear strip mailer boxes and self seal mailer boxes show the format in use.

Print and ordering tear strip boxes

The strip itself can be printed with a short instruction or left discreet, and the rest of the box can carry your full branding inside and out. Many brands print a brief returns explanation inside the lid, right where the customer will see it while deciding what to do, and add the second seal position clearly so the returns process needs no leaflet. Compare related styles in our cardboard mailer boxes range.

• Decide whether you need a single seal or a second strip for returns.
• Print a short opening instruction beside the pull tab.
• Test the strip on a packed sample to confirm a clean pull.
• Check that the opened box still closes squarely for its return journey.

Pricing depends on size, board, print and quantity, and on whether the returns strip is included, so every specification is quoted individually. Low minimum order quantities let growing brands trial the format on one product line first. Send your product sizes through our contact page for a quote and say whether returns are a priority, so the right strip configuration is specified.

tear strip boxes FAQs

What is a tear strip on a box?

A tear strip is a narrow perforated band built into the board of the box during manufacture. The customer pulls a small tab and the board separates along that line, opening the parcel neatly without scissors, a knife or torn cardboard.

Can a tear strip box be reused for returns?

Yes, if it is specified with a second adhesive strip. The first strip seals the box for the outward journey, the tear strip opens it, and the second strip lets the customer reseal the same box and send the item back without needing tape.

Will the tear strip come open during delivery?

It should not, provided the perforation depth is set correctly for the board being used. That is why a packed sample test matters, since a strip cut too deeply can separate in transit and one cut too shallowly will not pull cleanly.

Does a tear strip weaken the box?

Only along the intended opening line, and only once it is pulled. The rest of the panel keeps its strength, and the box remains usable afterwards, which is exactly what makes it suitable for return journeys.

What products suit tear strip boxes?

They suit products that are ordered online and may be returned, especially clothing, footwear, accessories and subscription goods. Any brand that wants a tidy opening and a simpler returns experience can benefit from the format.
