How Do Not Bend Envelopes Help Businesses Cut Replacement Costs

Quality do not bend envelopes prevent damage that costs far more than the envelope itself.

3 min readUpdated April 2025

The cost of damage

When a document, certificate, or print arrives bent or creased, the costs multiply. The item must be reprinted or replaced. A new envelope and postage are needed. Customer service time is consumed handling the complaint. And customer trust takes a hit that may cost future sales.

Replacement print/document: £2-50+ depending on the item
Reshipping cost: £1-5 for postage and new envelope
Customer service time: 10-15 minutes per complaint at staff cost
Reputation damage: negative reviews and lost repeat business

Quick answer

A quality board-backed envelope costing 30-80p prevents damage claims costing £5-50+ each. For businesses sending prints, certificates, or important documents, even a 5% damage rate on cheap envelopes costs far more than the premium for quality do not bend envelopes. Track your damage rate to calculate the exact ROI.

How envelopes prevent damage

The board insert prevents the envelope from flexing during handling.

Right-sized envelopes hold contents securely without room to shift.

DO NOT BEND markings prompt careful handling by postal workers.

ROI calculation

If you send 500 items per month in cheap envelopes with a 5% damage rate, that is 25 damaged items. At £10 average replacement cost, that is £250/month in damage. Upgrading to quality board-backed envelopes at 40p more each costs £200/month but reduces damage to under 1% (5 items, £50). Net monthly saving: £200.

Where to invest

Board weight: minimum 400gsm for documents, 600gsm for prints
Right sizing: match envelope to content for snug fit
Peel-and-seal closure: secure, consistent, tamper-evident
