Applicability of biaxially oriented poly(trimethylene terephthalate) films using bio‐based 1,3‐propanediol in retort pouches

Abstract: Poly(trimethylene terephthalate) (PTT) is a material that has intermediate properties between poly(ethylene terephthalate) (PET) and nylon, and produced by polymerizing bio‐based 1,3‐propanediol and terephthalic acid. In this study, the possibility of replacing existing biaxially oriented PET (OPET) and nylon 6 (ONylon) film with biaxially oriented PTT (OPTT) film is investigated to develop a more environmentally friendly retort pouch. In order to define actual problems in the retort pouch manufacturing proces… Show more

“…Since PTT exhibits the transparency and heat resistance of PET but a flexibility and elasticity comparable to that of nylon, the polymer has been investigated to replace both layers in retort pouches. [237,239] Recently, filaments for extrusion-based 3D printing were produced from PTT blended with biocarbon. [240] Figure 20.…”

“…It is noteworthy that ethylenediamine and ethanolamine, as nucleophilic reagents, could efficiently depolymerize pre-activated PET to produce the corresponding amides 5h and 5i, in which exposed hydroxyl and amino groups could serve as monomers for polyurethane. [24] Polytrimethylene terephthalate (PTT), [25,26] polybutylene terephthalate (PBT), [27] and polyethylene naphthalate (PEN) are polymerized from different aryl dicarboxylic acids and diols, broadening the application of polyesters, [28] along with the challenge for dismantling the compact structure of polyester plastics. Fortunately, efficient hydrolysis of pre-activated polyesters was realized at room temperature with the recovery rates of the corresponding products exceeding 95%, along with almost quantitative recovery of diols.…”

“…The motivation lies in the fact that 1,3-PD is one of the most important organic chemical materials which is being extensively applied in a range of industrial applications. For instance, it is used for synthesis of a biodegradable polymer known as polytrimethylene terephthalate (PTT) as well as production of detergents, cosmetics, composites and lubricants [ 23 , 68 , 69 , 70 , 71 ]. However, fermentation broths of 1,3-PD are complex media which, apart from the desired product, contain water, microbial cells, residual carbon source (e.g., glycerol) and various by-products (e.g., acetic acid, lactic acid, ethanol and 2,3-butanediol) [ 72 ].…”
