Design a new strategy for evaluating biodegradation mechanisms between plant tape and industrial tapes
AI summary Read the abstract
Researchers compared the biodegradation mechanisms and mechanical properties of conventional polypropylene-based packaging tapes (BOPP and BOPP/CaCO3) with a plant-based tape using laboratory testing. The plant-based tape showed superior degradability and breaking strength, with the study elucidating possible degradation mechanisms for each tape type.
Abstract China’s express delivery industry is developing rapidly, but the degradation and non-degradability of packaging tapes have been tremendously controversial and the degradation mechanism is not clear. In this work, the biodegradation behavior/mechanism and mechanical property of the polypropylene-based tape (BOPP tape), polypropylene doped with calcium carbonate (BOPP/CaCO 3 tape), and Plant-based tape (Plant tape) are discussed. It is found that the degradability ability and breaking strength of Plant tape are better than BOPP and BOPP/CaCO 3 tapes. Simultaneously, the possible degradation mechanisms of three tapes under three degradation ways were presented, providing a theoretical basis for developing their potential uses in the green packaging, express, and electronic industries.

Sustainable Biodegradable Biocomposites Reinforced With Natural Fibers: A Review on Processing, Properties, and Degradation
AI summary Read the abstract
As concern grows about plastic waste and microplastic pollution from synthetic polymers, this review examines biodegradable biocomposites reinforced with natural plant fibers as a more sustainable alternative. The authors find that these materials can match or exceed the mechanical performance of conventional plastics while actually degrading in the environment — but note a critical gap: lab biodegradation tests often do not reflect real-world conditions, creating uncertainty about how quickly these materials actually break down. Better standardized testing and lifecycle analysis are needed to confirm whether natural fiber biocomposites can genuinely replace conventional plastics at industrial scale.
Recent developments in bio-based polyethylene: Degradation studies, waste management and recycling
AI summary Read the abstract
Researchers reviewed the current state of bio-based polyethylene — plastics made from plants instead of oil — examining how well they degrade, how they can be recycled, and what still needs to improve before they can genuinely replace conventional plastics, noting that weight loss from degradation ranged widely from 1 to 47% depending on conditions.

Researchers reviewed the development of biodegradable packaging from starch films to bio-nanocomposites, examining how incorporating agricultural and textile waste fibers — cotton, jute, and hemp — improves mechanical strength and circularity as alternatives to petroleum-based plastic packaging.
Product Development with Accelerated Biodegradability: an Application in a Manufacturing Plastic Bags
AI summary Read the abstract
Researchers investigated the development of plastic bags with accelerated biodegradability as a strategy to reduce the environmental persistence of conventional plastic packaging. The study applied pro-degradant additives to plastic bag formulations in a manufacturing context and evaluated the resulting degradation rates and material performance characteristics.
A Review of Potency of Cassava Peel Waste and Seaweed Carrageenan as Environmentally Friendly Bioplastic
AI summary Read the abstract
This Indonesian review examines the potential of cassava peel waste and seaweed carrageenan as raw materials for making biodegradable bioplastics. Replacing conventional plastic packaging with plant-based alternatives could reduce the microplastic particles that accumulate in soil and water from degrading conventional plastics.
