“…In the same way, the researchers Filippova and Ivanova, showed the possibility of autoclaving PLA films for corneal implants. Although the autoclaving process increased the hydrophilicity and the internal surface roughness by up to five times [ 24 ], no inflammatory reactions or increased eye pressure were observed [ 25 ] in animal models.…”

How sterilization techniques accurately affect the properties of biopolymers continues to be an issue of discussion in the field of biomedical engineering, particularly now with the development of 3D-printed devices. One of the most widely used biopolymers in the manufacture of biomedical devices is the polylactic acid (PLA). Despite the large number of studies found in the literature on PLA devices, relatively few papers focus on the effects of sterilization treatments on its properties. It is well documented in the literature that conventional sterilization techniques, such as heat, gamma irradiation and ethylene oxide, can induced damages, alterations or toxic products release, due to the thermal and hydrolytical sensitivity of PLA. The purposes of this paper are, therefore, to review the published data on the most common techniques used to sterilize PLA medical devices and to analyse how they are affecting their physicochemical and biocompatible properties. Emerging and alternative sterilization methods for sensitive biomaterials are also presented.

Petrochemical-based plastics are prevalent in the packaging industry. However, given their detrimental impact on the environment, alternatives for future packaging materials are necessary. In this work, the inspiration for creating new types of packaging materials was taken from plant cuticle structures in nature. Potential eco-friendly solutions could be derived from plants. We fabricated cuticle-like materials using molecules found in natural cutins. A cross-linked material was developed through the melt polycondensation of hexadecanedioic acid and glycerol and with the addition of hydroxy-hexadecanoic acid, a noncross-linked terpolyester was obtained. Both compression molding and casting techniques resulted in flexible and transparent/translucent films. Both polyester films showed very low direct UV transmittance, but noticeable total UV transmittance. These semicrystalline materials exhibited water vapor transmission rates that were comparable or superior to other polyesters, such as polylactide and polycaprolactone. An intriguing characteristic was the rough surface exhibited by the copolyester following compression molding, which closely resembled the wax layer structure seen in many natural peels.
