Why Is Canadian Money Made of Plastic?

Canadian banknotes present a distinct appearance compared to currency in many other nations, notably due to their composition. Unlike traditional cotton-based paper, Canadian money is crafted from a polymer material. This noticeable difference often sparks curiosity, as the shift to polymer has significantly altered the tactile experience and visual characteristics of Canadian cash.

The Rationale for Polymer

The decision to transition to polymer banknotes was driven by compelling challenges with older currency. A significant concern was the increasing prevalence of counterfeiting, which posed a threat to the financial system’s integrity. By 2004, the counterfeit ratio for Canadian currency had escalated, causing some retailers to refuse higher denominations. This situation necessitated a more secure currency to deter illicit reproduction.

Another primary motivation was the relatively short lifespan of traditional paper currency. Cotton-based notes were susceptible to wear and tear, including tearing, creasing, and damage from moisture, leading to frequent replacements. The average paper note lasted approximately one year before needing to be withdrawn from circulation. This constant need for replacement resulted in high production costs for the Bank of Canada.

Physical Characteristics of Polymer Notes

Canadian polymer banknotes possess distinct physical attributes. They are manufactured from biaxially-oriented polypropylene (BOPP) plastic, giving them a smooth and slightly waxy texture. This material provides a different tactile experience, as it is less porous than paper and does not absorb liquids or oils, contributing to a cleaner feel over time.

A notable feature is the inclusion of transparent areas, integral to both their design and security. These clear windows are a direct result of the polymer’s properties, allowing for innovative visual elements. The polymer notes are slightly thinner and lighter than paper notes, weighing approximately 0.93 grams compared to 1.02 grams for paper notes. The inherent characteristics of the polymer material contribute to the notes’ enhanced durability and unique appearance.

Advanced Security Elements

The polymer material facilitates the integration of advanced security features, making them significantly more difficult to counterfeit than their paper predecessors. Transparent areas within the notes incorporate metallic images and holographic elements visible from both sides. These intricate details are challenging to replicate and serve as a primary visual cue for authenticity.

The notes also feature raised ink on specific elements, such as the large portrait and denomination number. This tactile feature allows individuals to feel texture differences, providing another layer of verification. Some denominations include hidden numbers visible under ultraviolet (UV) light, along with color-shifting images. These sophisticated anti-counterfeiting measures are enhanced by the polymer substrate.

Longevity and Economic Advantages

The enhanced durability of Canadian polymer banknotes offers significant longevity and economic advantages compared to older cotton-paper notes. Polymer notes are notably more resistant to tearing, creasing, and moisture, which extends their lifespan considerably. While paper notes typically lasted about one year, polymer notes are expected to endure at least 2.5 times longer, with some estimates suggesting they can last between two and five years longer.

This extended durability directly translates into substantial cost savings for the Bank of Canada. Although the initial production cost of a polymer note is higher, their prolonged circulation life means fewer notes need to be printed and distributed over time. The Bank of Canada anticipated saving approximately 25% on production costs by switching to polymer notes due to reduced replacement expenses. This increased longevity also contributes to a reduced environmental impact.
