Resins: An Integral Component in the Packaging Sector

Packaging resin is a type of polymer material that can shape, extrude, or solidify into various forms and types by enabling the production of packaging items like containers, bottles, films, and similar products. These resins are distinguished by their molecular structure, physical properties, and chemical composition, all thoroughly designed to suit the specific requirements of different applications. 

Packaging resin plays an important role across various industries, serving as a fundamental element in the manufacturing of multiple packaging materials. It involves a diverse range of polymers that significantly contribute to the production of packaging options. These resins are selected based on their durability, ability to cater to the diverse needs of distinct industries, and versatility.  

In the food and beverage sector, packaging resins are essential for making beverage bottles, flexible packaging films, and meal containers. These resins possess different levels of barrier properties against gases, moisture, and other external elements. In the healthcare sector, they are used as medical-grade materials to protect medical devices and medicines.

The report published by Allied Market Research on the packaging resins market indicates that the industry is anticipated to experience the fastest growth with 7.4% CAGR by 2032. Based on country, China is expected to hit 8.4% CAGR during the forecast period. Italy, on the other hand, is projected to rank second with 8.3% CAGR throughout the forecast timeframe. By type, the polystyrene (PS) segment would manifest a notable CAGR of 8.2% by 2032. Simultaneously, in terms of application, the healthcare segment is anticipated to showcase a noteworthy CAGR of 8.0% from 2023 to 2032. The construction segment, at the same time, is estimated to dominate the market during the forecast period. 

Eco-friendly packaging: An emerging trend for a sustainable future 

The surge in demand for eco-friendly packaging polymers drives the adoption of sustainable packaging materials. These resins are crucial in manufacturing items like plastic containers and bottles. Conventional resins derived from fossil fuels have a detrimental environmental impact, whereas eco-friendly alternatives are either compostable, sourced from renewable materials like corn starch, or biodegradable.  

Bioplastics, extracted from sources such as sugarcane, offer an eco-friendly substitute for common plastics. Stringent regulations targeting single-use plastics and increasing consumer demand for sustainable products are driving this transition. Consequently, companies are actively seeking alternative options. Innovations such as plant-based materials are helping manufacturers in reducing their environmental footprint. 

Seaweed-based packaging resin secured federal funding on 18th October 2023 

A company specializing in bio-based materials for packaging, Sway, has disclosed its receipt of a SBIR (Small Business Innovation and Research) grant from the NSF (National Science Foundation). Sway intends to diversify its feedstock portfolio by incorporating elements such as unrefined seaweed, processing byproducts, and invasive macroalgae. 

Sway has stated that their Thermoplastic Seaweed Resin (TPSea) holds the potential for converting seaweed into adaptable packaging solutions, such as retail bags, polybags, mailers, food packaging, and pouches. The material is compatible with the current plastic processing infrastructure for ease of use. The funding is utilized to expand the production of the company's next-generation biodegradable product, predominantly made from seaweed and capable of undergoing a melting process. 

To conclude, the global packaging resin industry is gaining momentum and is expected to expand even more in the future.
