Brand Owners Standardize Mixed-Material Packaging Specifications
Major brand owners have begun standardizing packaging specifications that combine fiber-based and bioplastic components within the same product line, rather than committing exclusively to one material family, as they seek barrier performance from bioplastic coatings alongside the recyclability and compostability brand teams associate with fiber substrates. This is pulling fiber converters and bioplastic resin producers into closer co-development relationships than the two industries previously maintained, since a mixed-material specification requires both suppliers to coordinate performance testing jointly. Brand owners that completed this standardization are citing it directly in sustainability reporting, pushing additional categories toward similar mixed-material specifications. This dynamic also shapes the biodegradable water bottles market, valued by MMA at USD 3.8 billion in 2025 and expected to reach USD 11.4 billion by 2036.
