Abstract Aiming to achieve different characteristics with polypropylene copolymer, especially in relation to transparency similar to glass packaging, the effect of the addition of a clarifying agent derived from sorbitol to the polypropylene copolymer was studied. A specific cup shape packaging used for Brazilian cream cheese was applied. The samples were produced with different amounts of clarifying agent and were injected in industrial equipment. Further, the samples were characterized in regard to opti‑ cal, mechanical and thermal properties. The results confirmed that the addition of clarifying agent, besides improving the transparency of the polypropylene copoly‑ mer, also increases the tensile strength. Moreover, from the view of applicability, the clarifying agent was demonstrated to be advantageous for the polypropylene copoly‑ mer production of Brazilian cream cheese packaging.

Introduction Packing is a key activity in industry, since it comprises different steps and areas throughout the supply chain. The main role of a package goes beyond the pres‑ ervation and protection of products against damages; it not only facilitates the transport but also identifies the product, differentiating it from competitors’ items and providing useful information to consumers [1]. In this way, packaging tech‑ nology assumes a strategical role for a company, especially if we consider the food industry; in this sector, packaging can represent a huge competitive advan‑ tage. The advantages come from various factors, such as opening up opportuni‑ ties for new distribution channels, providing a better visual presentation quality, allowing lower costs, increasing profit margins, differentiating and highlighting the product and brand, and improving the logistics service for customers [2]. Traditionally, it is well known that the main purpose of packaging is to pro‑ tect and preserve
