Resumo
Neste trabalho será desenvolvida uma análise das aplicações de embalagens
biodegradáveis em âmbito industrial, levando-se em conta fatores como ampliação de escala,
propriedades físicas e de barreira requisitadas, e maquinabilidade do processo de produção, com
uma abordagem voltada para a Indústria Alimentícia. Hoje, as embalagens mais utilizadas são
formadas por filmes de polipropileno e polietileno (resinas poliolefínicas), que apresentam
excelente barreira à umidade, mas que geralmente necessitam do revestimento de polímeros
sintéticos para a barreira à gases, acarretando em aumento no custo de produção e não
reciclabilidade do material. A substituição destes revestimentos sintéticos por polímeros
naturais capazes de formar filmes com barreira efetiva a oxigênio une o conceito de polímero
verde a uma alternativa mercadológica e sustentável, transformando a embalagem em um
produto menos danoso ao meio ambiente, de vida circular e com menor pegada de carbono.
Uma visão expositiva das opções mais conhecidas de biopolímeros é realizada, avaliando o
processo produtivo de embalagens com um estudo de caso sobre o PLA (Polilático Ácido) e,
ao final do trabalho, são levantadas as principais inovações presentes no mercado atual com
uma discussão a respeito dos desafios mercadológicos encontrados. Propostas alternativas para
um aumento na produção de embalagens biodegradáveis são debatidas, ressaltando que o
cenário ideal formado por polímeros de fontes renováveis e biodegradáveis trazem desafios
como: a disponibilidade de biomassa e sua competitividade de território com o mercado
alimentício, a substituição das propriedades físicas necessárias para uma boa performance de
barreira e o descarte adequado dos resíduos das embalagens que requerem uma destinação
correta para gerar um impacto positivo no meio-ambiente.
In this paper, an analysis of the applications of biodegradable packaging in the industrial scope will be developed, taking into account factors such as scale expansion, required physical and barrier properties, and machinability of the production process, with an approach focused on the Food Industry. Today, the most used packages are made of polypropylene (PP) and polyethylene (PE) films (polyolefinic resins), which present an excellent barrier to moisture, but which generally require the coating of synthetic polymers for the gas barrier, resulting in an increase in production cost and not material recyclability. The replacement of these synthetic coatings by natural polymers capable of forming films with an effective barrier to oxygen unites the concept of green polymer to a marketing and sustainable alternative, transforming the packaging into a product that is less harmful to the environment, with a circular life and with a smaller footprint. carbon. An expository view of the best-known biopolymer options is carried out, evaluating the packaging production process with a case study on PLA (Polylactic Acid) and, at the end of the work, the main innovations present in the current market are considered with a discussion regarding the market challenges encountered. Alternative proposals for an increase in the production of biodegradable packaging are debated, emphasizing that the ideal scenario formed by polymers from renewable and biodegradable sources brings challenges such as: the availability of biomass and its territory competition with the food market, the replacement of the physical properties necessary for a good barrier performance and the proper disposal of packaging waste that provide a correct destination to generate a positive impact on the environment.
