In the United States, a huge regulatory transformation is underway in consumer goods. Multi-layer packaging has been a main component of the retail sector since decades ago, protecting, transporting, and displaying products. When the plastic linings, metallic foils and paperboard substrates are combined, it would be a simple matter for manufacturers to develop containers that were both durable and attractive. This complexity with materials has posed a huge challenge to the recycling ecosystem, however.
Most of the multi-material packaging waste in the U.S. is sent directly to landfills since it is not easily separated by typical municipal sorting equipment. In response, some states have passed aggressive Extended Producer Responsibility (EPR) laws, such as California, Oregon, Colorado, Minnesota and Maryland. These tough regulations shift the packaging waste burden back to commercial brands and make packaging waste recycling more expensive. In order to steer clear of high fines for non-compliance and to lure eco-friendly consumers, contemporary businesses are turning to a pioneering approach – mono-material design.
What does Mono-Material Packaging Design mean?
The basic idea behind mono-material engineering is to create a full product using a single, homogenous material base. A mono-material container is a paper container with a clear plastic window, or a paper container that is accented with a metallic foil that does not affect the paper recycling stream.
100% Curbside Compatible – The container can be dropped off in the standard residential blue bins because it is made from a single material type (such as 100% natural Kraft paperboard or 100% corrugated fiber) and so does not require the consumer to separate the components.
These single-substrate pieces can be automated sorted by optical sorting systems at the Material Recovery Facilities (MRFs) as they arrive at the facility, making them extremely efficient to process. This significantly increases processing speeds and results in a much better quality recycled raw pulp.
Engineering Challenge: Reimagining the Box Structure
The switch from a traditional composite box to a clean mono-material box needs a careful structural planning. Brands can’t just strip away the protection without coming up with some ingenious strategies for mimicking the effect. The challenge is to make one material do three things: to shield the product, to act as a partition of the product and to be the main marketing canvas in the same moment.
Industries such as those manufacturing moisture-sensitive and delicate personal care products require careful handling in this structural shift. Reflect on the natural skin care and artisanal personal care sector within the U.S. where items are often subject to moisture throughout the transportation and storage process. In contrast to the conventional plastic films and thick chemical coatings used to preserve a product, leading brands are moving towards high-density paper fibers without bleaching.
Specialized and structurally sound custom soap boxes logo elements enable these eco-conscious companies to completely get rid of the plastic. The whole pack is extremely organic with the use of advanced structural locking tabs, folding paper dividers and soy-based inks. The box preserves all natural oils of the product, showcases the brand’s high-end positioning to perfection and becomes completely invisible in normal household recycling containers, without leaving behind any trace of micro-plastics.
Navigating Stricter US Recyclability and Truth-in-Labeling Laws
This is no longer enough: when a brand is marketing products in the U.S. marketplace, it must be clear that an item is “eco-friendly” or “recyclable” if it’s a digital storefront or on a printed package. Brands are banned from using the famous chasing arrows logo or general recycling claims unless the material matches the tough real-world collection standards set by the Federal Trade Commission (FTC) in its Green Guides or by state regulations brought about by the aggressive SB 343 Truth in Labeling compliance rules enforced in California.
In order to be considered ‘widespread recycling’ it will be accepted by the municipal recycling facilities which serve at least 60% of the population, sorted by local facilities and used as a regular source of raw material for new products. An unlamented, mono-material paper box aces these real-world tests in infrastructure. When you use chemical-free glue, non-separable plastic windows and metal foils are eliminated, your packaging is eligible for clear recycling markings and you won’t have to worry about expensive consumer greenwashing litigation.
Benefits of simplicity are available for capitalization
Environmental compliance is the main incentive for adopting mono-material, but the logistic and economic benefits are tremendous for expanding companies.
Having to purchase the pieces of the packaging the outer box, the plastic inner tray, and the acetate window sticker separately means having to manage multiple vendors, facing unpredictable lead times, and having to pay multiple shipping invoices. The transition to a single, combined box with a single material helps you reduce your supplier base to one.
Fewer Manufacturing Steps: Your overall production steps are significantly reduced with single-substrate production runs which will help to lower your unit costs and tooling fees.
Mono-material paper layouts are naturally lightweight, fold completely flat, and enable brands to pack more units into one shipping pallet, while also greatly lowering domestic freight costs.
A True Circular Economy: Design
For retailers in America, tomorrow’s business is about companies that are integrating circularity into their product life cycles from the ground up. One of the traditional “take, make, waste” approaches is gradually coming to an end because consumers now have higher expectations and stricter state-level environmental regulations.
Sticking with a mono-material approach can help your business avoid expensive eco-modulated fines, reduce supply chain waste at the point of operation, and create a strong consumer loyalty and trust relationship between your company and your highly selective customers. Simplifying packaging material is more about the purity of the material and less about the packaging container, which helps to save your bottom line, while keeping your packaging to pass through every component of the US curbside sorting system.
