The PLA plastics used in this paper were IngeoTM 2003D (NatureWorks © LLC, Minnetonka, MN, United States) and Futerro PLA was provided by Futerro S.A. (Escanaffles, Belgium). These bioplastics were originally in granulated form. Prior to all experimental work, the PLA bioplastics were processed to transform the granules into powder (Choe et al., 2022 (link); García-Depraect et al., 2022 (link)). PLA granules (100 g) were ground together with alternate layers of dry ice (200 g, IJsfabriek, Belgium) using a commercial blender (Krups Blender, Prep Expert S7000; 1,000-W). A total of 15 grinding cycles (5 min grind; 3 min rest) was used to avoid overheating of the appliance and reduce sublimation.
The grounded PLA powder was dried overnight at room temperature. Finally, manual sieving using stainless steel sieves of 100, 125, 150, and 250 µm (Test Sieve ISO 3310/1, Fisherbrand) was conducted to classify the powders based on particle size. The particle size used was from 125 to 250 µm as recommended by ISO 14 852 for aerobic aqueous conditions. These particles were sterilized with 70% ethyl alcohol prior to working under aseptic conditions.

A commercial grade of PLA designed for packaging applications, the IngeoTM 2003D, was purchased from NatureWorks (Minnetonka, MN, USA). This grade presents a specific viscosity of 1.24 and a melt-flow rate of 6 g/10 min (210 °C, 2.16 kg). The yerba mate (Ilex paraguariensis) residues were collected after consumption of a yerba mate infusion in our laboratory. Bombyx mori cocoons were supplied by Instituto Murciano de Investigación y Desarrollo Agrario y Alimentario (IMIDA, Murcia, Spain). All chemicals and solvents were purchased from Merck (Madrid, Spain), were of analytical grade, and were used without further purification, unless otherwise specified.

The first component of the blend was polylactide (PLA), IngeoTM 2003D (provided by NatureWorks LLC, Minnetonka, MN, USA) with a glass transition temperature of 328–333 K, peak melt temperature of 418–433 K and with a melt flow rate of 6 g/10 min (conditions: temperature 483 K, nominal load 2.16 kg). The density of this material amounts to 1.24 g/cm3. The second ingredient was polyhydroxybutyrate (PHB), which belongs to the polyhydroxyalkanoate group of polymers (PHA) and was obtained from Simag Holdings LTD (Hong Kong, China). This material, containing 12 mol% 4-hydroxybutyrate, is characterized by an average molecular weight of 520 kDa and a density of 1.25 g/cm3. The melt flow rate is 18 (conditions: temperature 443 K, nominal load 2.16 kg), and the moisture content is 0.05%.

Example 1
Demonstrating the adhesive strength of a three-layer sheet made of an acrylic outer layer over an inner layer of biopolymer/acrylic alloy over an acrylonitrile-butadiene-styrene (ABS) substrate.
Several multilayer sheets were made by coextrusion of an outer layer of an impact modified acrylic (Solarkote® A) over a polylactic acid/acrylic modified with an acrylic impact modifier (PLA/PMMA-IM) inner layer over an ABS substrate layer. The PLA/PMMA-IM layer contained 33% acrylic core-shell impact modifier and PLA content was varied from 30 to 50%. (PLA used was Natureworks INGEO® 2003D)
All multilayer sheets showed excellent adhesion between both the Solarkote® A layer and the PLA/PMMA-IM layers and between PLA/PMMA-IM layers and the ABS layer. The layers could not be manually separated.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
