The Cost Difference Between Paper and Plastic Mailers Explained
The true cost of paper vs plastic mailers: beyond the per-unit price.
Unit cost comparison
Quick answer
Paper bags cost 5-15p more per unit, but the total cost difference narrows significantly when you factor in Plastic Packaging Tax (saved), branded label elimination (saved), and customer lifetime value (increased). For many businesses, paper is cost-neutral or cheaper when all factors are included. The per-unit price comparison alone is misleading.

Tax implications
The Plastic Packaging Tax adds approximately 1-3p per poly mailer. Paper bags are exempt. This narrows the unit cost gap significantly. As the tax rate increases over time, the economics will increasingly favour paper.
