Introduction Polyurethane is an important class of polymer with many advantageous properties, its chain structure is composed of alternating sequences of hard and soft segment.
Results and discussion According to the principle of polymer chemistry, the reaction of diisocyanate and diol is a kind of step-type polymerization.

Commercial plastics for food packaging include simple homopolymers polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), aluminum sheet (Surlyn), ethylene vinyl alcohol copolymer (EVOH), and others or copolymers such as low-density polyethylene (LDPE), medium-density polyethylene (MDPE), high-density Among the plastic materials, polyethylene (PE) and polypropylene (PP) (homo- and copolymer) are mostly used in package design preferred for contact with the product both in monolayer and laminated or coextruded structures because of their good chemical resistance and inertness to most foods, good barrier properties to water, and thermosealability.

Fig. 6 Visualization of 3D corset with support structures In the AM process of a “2D” model of the orthopedic corset was chosen the same biomaterial (PLA bioplastic) and AM method (FDM).
This is due to the simple flat shape of the “2D” model and the associated pointless of the supporting structures.
The 3D model of the corset is made in the final shape using the support structures which extends the production time, increases the PLA material consumption and consequently increases the cost of corset production itself.

Valldor by partial substitution of Y3+ with low valence Ca2+ cations in perovskite structure [11].
Previous studies have demonstrated a correlation between the compound structure and his properties, especially due to the variable cobalt ions valence and it was found that oxygen adsorption properties can be modified greatly by Y3+ ions substitution in the original structure of YBaCo4O7.
