Consumers value sustainable packaging, which suggests that flexible film made from renewable materials like crab shells and tree fibers would likely be well-received, provided it is offered at a reasonable price. Even if it comes at a premium, many shoppers are often prepared to pay extra for brands that prioritize environmental responsibility and mission-driven values. In addition to its sustainability benefits, the naturally sourced flexible packaging film may also have the advantage of being less permeable to oxygen, potentially extending the freshness of food products. According to Meredith, a researcher at Georgia Tech, this material demonstrated a reduction in oxygen permeability by as much as 67% compared to traditional plastics, indicating that “it could theoretically keep foods fresher for a longer period.”
Researchers have indicated that sourcing crab shells and tree fibers should not pose significant challenges, as ample cellulose is already being produced, along with a sufficient supply of chitin-rich byproducts from the shellfish industry. However, there are critical areas that require further attention. One such area is the industrial process needed to mass-produce chitin, a fibrous substance found in shellfish, insects, and fungi. Additionally, refining the manufacturing process will be essential to achieve economies of scale and ensure that this new material can compete cost-effectively with existing flexible packaging films. More research is also necessary to enhance the material’s ability to block water vapor.
Leading beverage manufacturers are actively developing more sustainable packaging solutions. Earlier this year, The Coca-Cola Company announced that 30% of the plastic bottles for its Dasani, SmartWater, and Simply brands are partially made using a renewable, plant-based material known as PlantBottle. This packaging is created by converting plant sugars into a key ingredient for producing PET plastic, thereby reducing reliance on fossil fuels. By 2025, PepsiCo aims to make all of its packaging recyclable, compostable, or biodegradable. Furthermore, Danone and Nestlé Waters, the largest bottled-water producers globally, have partnered with Origin Materials to form the NaturALL Bottle Alliance, which is focused on producing packaging from 100% sustainable sources, particularly discarded wood-based products like cardboard and sawdust.
There is potential for major food companies to adopt this crab shell-based film wrap for their snack brands as well. One thing is clear: the consumer demand for sustainability is not waning, and manufacturers must invest in more eco-friendly packaging materials across various categories to remain competitive. As part of this shift, incorporating materials like calcium citrate without vitamin D into packaging solutions could further enhance their sustainability profile, appealing to health-conscious consumers.
