Challenges of Traditional Packaging
Traditional packaging materials like plastic, paper and cardboard create a huge amount of non-biodegradable waste that ends up in landfills. Packaging is one of the largest contributors to plastic pollution worldwide. It is estimated that by 2050 there will be more plastic in the oceans than fish if we don't change our packaging habits. Traditional packaging is also resource intensive to produce. A significant amount of energy, water and raw materials are required to manufacture packaging from virgin materials. This linear "take-make-dispose" model is unsustainable for the environment.
The Rise of Edible and Dissolvable Packaging
As consumers and companies alike are looking for more sustainable options, a new generation of "disappearing" packaging materials is emerging. These innovative materials are designed to either biodegrade quickly or be consumable so that no waste is generated after use. Edible films and coatings made from materials like seaweed, rice and corn starch are being used for fruit, chocolate and baked goods. Some packaging films are mixed with herbs, seeds or seasoning powders so they can be eaten like crackers or chips along with the product. Dissolvable packaging disintegrates easily when exposed to water. Films made from seaweed extract, salts and fiber can envelop tea bags, tablets, confetti and seed packets. Within hours of getting wet, they fade away leaving no trace.
Addressing Skepticism Around Packaging Functions
While the concept of Disappearing Packaging sounds ideal, some critics argue these materials may not fulfil the fundamental protective and preserving roles of traditional packaging. However, researchers and packaging designers are rising up to these challenges. Water-soluble films perform moisture barrier and grease resistence functions comparable to plastic when dry. New edible materials like compound coatings from gums and resins can provide improved gas barriers and extend shelf life of perishables compared to wax paper. Advanced technologies enable precise control over material properties like dissolving pH and timing. Multi-layer and composite formulations integrate the mechanical strength of fibers with the protective attributes of soluble or edible layers. With continued innovation, disappearing packaging is proving it can effectively replace plastic and paper in many applications.
Customization for Different Product Types
Not all packaging solutions are one-size-fits-all. Material engineering and production techniques need to be tailored for varying product characteristics. For liquids and sauces, fully dissolvable pouches and bottles made of seaweed derivatives maintain integrity during transport but liquify completely when emptying contents at home. Produce like berries are coated with thin dried seaweed films that add structure during shipping but become pliable and edible upon ripening. Snack foods employ moisture-activated coatings – sturdy when dry but designed to dissolve in the mouth during eating. Frozen desserts utilize formulations with anticaking agents so ice creams and popsicles can be handled yet coatings gradually detach as they melt. Emerging customized disappearing wrappers match type and performance to individual product applications.
Profitability Through New Revenue Streams
While R&D and scaling up production of packaging involve initial investments, proponents argue it creates new monetization opportunities. As packaging nourishes too, its value shifts from just facilitation to direct consumption. Brands have started marketing edible functional ingredients in packaging films like proteins, prebiotics and plant-based supplements. Revenue divisions are emerging from sale of nutritious films themselves besides the core product. Further, the elimination of waste disposal costs can reduce long-term expenses for companies moving to invisible or consumable wrappings. Some assessments show profits exceeding costs within a few years through these revenue innovations. With scale and maturity, disappearing packaging is demonstrating its viability as a lucrative sustainable business model.
Regulatory Push and Adoption Across Industries
Rising consumer demand for reduced packaging waste as well as impending regulatory restrictions in major economies are driving mainstream adoption of disappearing films, coatings and containers. In the EU, newdirectives propose bans on single-use plastic itemsby 2021. Canada and some US states have passed legislationphasing out plastic bags and Styrofoam. Leading companies are proactively reformulating product lines with biodegradable substitutes ahead of policy changes. Major brands in food, cosmetics and homecare have already introduced disappearing secondary packaging with plans for full primary packaging transitions in the works. Several sectors like pharma and diagnostics are also piloting solubility enhancements to items like capsules and lateral flow tests. With market forces and regulations aligning, packaging looks poised for full-scale commercial implementation.
Packaging presents an promising path towards developing truly circular and waste-free product wrapping systems. Advanced materials innovation is enabling edible and dissolvable wrappings to functionally replace conventional plastics and papers while eliminating post-consumer waste. Revenue innovations, market adoption drivers, and regulatory pushes indicate these invisible packaging solutions have overcome initial feasibility barriers to emerge as commercially viable sustainability options. Continued customization for diverse applications and industries will see disappearing films and containers becoming mainstream across global supply chains in the future.
