Bioplastics for food packaging: applications, advantages and what to consider

Bioplastics are transforming food packaging, combining functionality with a reduced environmental impact. Discover their applications, the differences between biodegradable and compostable materials, and the keys to developing compostable packaging.

Bioplastics for Food Packaging The food sector is seeking packaging solutions that combine functionality, safety, and reduced environmental impact. Bioplastics and compostable materials offer new alternatives for developing more sustainable packaging. It is important to differentiate between bioplastics, biodegradable materials, and compostable materials, as they do not all have the same characteristics. The choice of material will depend on the application, its properties, and the technical and regulatory requirements. Applications Compostable materials can be used in different packaging solutions: - Single-serving packets: for oils, sauces, dressings, and other products in individual formats. - Trays: for fruits, vegetables, and other foods that require protection and presentation. - Other solutions: materials adapted to the specific needs of each project. Regulations and Food Contact The development of compostable packaging must consider applicable regulations. In Spain, Royal Decree 1055/2022 establishes the framework for packaging and packaging waste. For food contact materials, Regulation (EC) 1935/2004 and Regulation (EU) 10/2011 for plastic materials must also be considered. For fruits and vegetables, the regulations include certain exceptions to bulk sales, such as products packaged in batches of 1.5 kg or more. Key Material Factors: Developing compostable packaging requires analyzing its application, strength, flexibility, processability, compatibility with manufacturing processes, food contact properties, and compostability. At Prime Biopolymers, we develop biodegradable and compostable materials for food packaging, single-dose containers, and other applications, tailored to the needs of each project.
