Resumen de: WO2025227027A1
The disclosure relates to ionizable polyesters containing repeat units having polymeric or oligomeric polyester segments or residues and linkers between the polyester segments having ionizable groups such as carboxylic acid groups and their related salts, for example ammonium salts. The ionizable polyesters can further include repeat units with functional groups other than polyesters to impart additional barrier properties, pH-responsive properties, and/or reactive properties. The ionizable polyesters can be used as water- and oil-resistant barrier coatings on cellulosic substrates such as paper, providing good barrier properties while also providing coatings and coated articles that are biodegradable, compostable, recyclable, and/or repulpable. The ionizable polyesters can be provided in an aqueous emulsion containing a salt form of the ionizable polyesters, which is a particularly suitable form for applying a coating of the ionizable polyesters onto a substrate such as paper.

The present invention relates to a polylactic acid (PLA)-based composite plastic and a use thereof. In order to reduce the inherent brittleness of a PLA material, the present invention can provide a PLA-based composite plastic in which a reinforcing material is mixed, the reinforcing material is dispersed and composited in a biodegradable polymer matrix containing PLA so as to prepare a composite filler, the composite filler is mixed with a pure PLA material and molded so that mechanical integrity satisfying both tensile strength and toughness is ensured while the amount of the reinforcing material is lowered to be less than the total weight of PLA, and transparency equivalent to that of the inherent physical property of PLA is implemented. Provided is the PLA-based transparent film, which can be applied to industrial packaging containers, food containers and food packaging applications that require the physical property.

The present application provides an aliphatic-aromatic copolyester, a preparation method therefor, and an application thereof. The aliphatic-aromatic copolyester comprises the following components: a component A, comprising the following acid components: a1) 63-69 mol% of terephthalic acid, or a derivative thereof, or a mixture thereof, based on the total moles of a1) and a2); a2) 31-37 mol% of adipic acid, or a derivative thereof, or a mixture thereof, based on the total moles of a1) and a2); and component B: 1,4-butanediol, in an amount at least equimolar to component A. The aliphatic-aromatic copolyester has a crystallization enthalpy of -20 to -46 J/g. The aliphatic-aromatic copolyester of the present application is used for preparing packaging film, which has a high heat-sealing strength even after prolonged storage, and the impact on the degradation performance of the packaging film is minor.

The resealable bag has a main body including a resealing layer. The resealable bag is selectively positionable between an open, unsealed position and a closed, sealed position. When the resealable bag is in the closed, sealed position, the resealing layer is in a deformed shape. Advantageously, the resealable bag can be repeatedly rolled and sealed, and unrolled and unsealed, as desired without the use of additional integrated or non-integrated sealing mechanisms.

A 100% biodegradable, food-safe, UV-curable, and self-renewing adhesive composition is disclosed, formulated as a one-part system requiring no premixing. The composition comprises about 30-40% nanomaterial reinforcement agents, 20-25% biopolymer matrix components, 13-20% crosslinking and curing agents, 15-20% additives and enhancers, and approximately 0.98% natural antioxidants. Through controlled UV exposure, it achieves adjustable tensile strengths from ̃15 psi to 21,525.9 psi, exhibits antimicrobial properties, and remains wash-reactivatable retaining effectiveness after ̃300-350 wash cycles. It tolerates temperatures from ̃40° C. to 220° C., meets FDA/EFSA standards, and is hypoallergenic for prolonged skin contact. By enhancing knot security in shoelaces, offering reusable performance for food packaging, enabling layered tape solutions for automotive and aerospace, and providing biodegradable bonding for medical devices and other consumer goods, this advanced adhesive addresses multiple industries that require long-term, environmentally friendly adhesion without performance loss.
